Pennsylvania Child Abuse Recognition and Reporting

Introduction   

For healthcare professionals who work with children in any capacity, there almost always comes a time when the very troubling issue of child abuse is encountered. Though disturbing, abusive situations for children are the reality for nearly 380,494 children nationally each year (7). Child abuse may encompass physical or sexual abuse, neglect, exposure to violence or drug use, or any other physically or psychologically harmful situation. The effects of child abuse can last long into adulthood, and children who are abused grow up to have higher rates of depression, anxiety, addiction, eating disorders, post-traumatic stress disorder (PTSD), and many other psychological and medical problems (10). 

Child Welfare in the State of Pennsylvania 

The Pennsylvania Child Protective Services Law (CSPL) (23 Pa.C.S. Chapter 63, Child Protective Services) (Pennsylvania General Assembly, 2021) was enacted in 1975 to protect children and provide a framework for law enforcement and persons identified as mandated reporters to take the appropriate action to ensure the safety and stability of the family. 

In order for abusive situations to be reported accurately and handled most effectively, it is first important to understand how the Child Welfare System works, specifically for this course, in the state of Pennsylvania. The state supervises and provides funding for each of the 67 counties which administer child welfare services. One of the roles of each county is to handle reports from both Child Protective Services (CPS) and General Protective Services (GPS). 

In the Commonwealth of Pennsylvania, child welfare is state-supervised and county-administered. When a case is reported, trained professionals categorize the report either as a CPS case, GPS case, or not needing further processing. Cases identified as CPS require abuse investigations because the alleged act or failure to act has been identified as one of the ten categories of abuse in the CPSL. 

Child Protective Services Cases 

Child Protective Services (CPS): The services and activities provided by the department and each county agency for child abuse cases.  

CPS handles reports that there is a reasonable suspicion a child is the victim of non-accidental physical injury, sexual abuse or exploitation, or injury resulting from neglect or omission of care by a parent or caregiver. These reports require an investigation (6).  

Examples of CPS cases:   

  • Causing bodily injury to a child through any recent act or failure to act. 
  • Fabricating, feigning, or intentionally exaggerating or inducing medical symptoms or disease results in potentially harmful medical evaluation or treatment to the child through any recent act. 
  • Causing or substantially contributing to serious mental injury to a child through any act or failure to act or a serious of such acts or failures to act. 
  • Causing sexual abuse or exploitation of a child through any act or failure to act. 
  • Creating a reasonable likelihood of bodily injury to a child through a recent act or failure to act. 
  • Creating a likelihood of sexual abuse or exploitation of a child through any recent act or failure to act. 
  • Causing serious neglect of a child. 
  • Engaging in the following recent per se acts. 
  • Causing the death of the child through any act or failure to act. 
  • Engaging a child in a severe form of trafficking in persons or sex trafficking, as those term are defined under section 103 of the Trafficking Victims Protection Act of 2000. 
General Protective Services Cases 

General Protective Services (GPS): Those services and activities provided by each county agency for cases requiring protective services. As defined by the department in regulations.  

GPS responds to reports that do not quite reach the level of abuse or neglect but require intervention to prevent serious harm from occurring. These incidents include issues like improper shelter or hygiene, school truancy, inappropriate discipline, and being left without a parent or guardian for longer than is age-appropriate or abandoned altogether. These allegations are less severe and do not require a full investigation, mostly offering an opportunity for parents or caregivers to receive education on how to improve conditions to best support a child’s health and development (3). In these cases, the act or failure to act is detrimental to a child but does not fall under the 10 categories of child abuse as per the CPSL. These services can assist parents in being able to recognize and correct the conditions that are harmful to their children.   

Cases identified as GPS require an assessment for services and support. In these cases, the act or failure to act is detrimental to a child but does not fall under the ten categories of child abuse as per the CPSL. These services can assist parents in being able to recognize and correct conditions that are harmful to their children.  

Examples of GPS (Services to prevent the potential for harm to a child who meets one of the following conditions):  

  • Is without proper parental care or control, subsistence, education as required by law, or other care or control necessary for his physical, mental, or emotional health or morals.  
  • Has been placed for care or adoption in violation of the law.  
  • Has been abandoned by his parents, guardian, or other custodian.  
  • Is without a parent, guardian, or legal custodian.  
  • Is habitually and without justification truant from school while subject to compulsory school attendance.  
  • Has committed a specific act of habitual disobedience of the reasonable and lawful commands of his parent, guardian, or other custodian and who is ungovernable and found to be in need of care, treatment, or supervision.  
  • Is under ten years of age and has committed a delinquent act.  
  • Has been formally adjudicated dependent under section 6341 of the Juvenile Act (relating to adjudication), and is under the jurisdiction of the court, subject to its conditions or placements and who commits an act which is defined as ungovernable in subparagraph (VI).  
  • Has been referred to under section 6323 of the Juvenile Act (relating to informal adjustment), and who commits an act which is defined as ungovernable in subparagraph (VI). 

It should be noted that the person filing the report may list their claim as suspected child abuse, but it is ultimately up to the person conducting the investigation to determine if abuse or maltreatment has occurred and if the suspicion qualifies for filing through CPS or GPS. The child abuse investigator for the county is responsible for conducting the investigation and officially classifying the reports; mandated reporters should not attempt to investigate the situation or gather further information than what first prompted their report (6).  Discuss in framework of duties of the mandated reporter and reasonable suspicion of abuse. 

Case Study  

Case Study No. 1- please read the scenario and reflect on the type of abuse that is occurring. 

A mother of two small children aged six and nine is planning to go on a three-day weekend trip with her new boyfriend. She is unable to find adequate childcare for the children and does not want to take them along on the trip, so she decides she will leave her children alone for three days. She figures there is enough food and water to keep them satisfied for three days. She gives them strict instructions not to answer the door or the phone to anyone and to not make loud noises. The neighbors notice some strange noises coming from the house and go by to check in. They discover the children are alone at home. They tell the neighbors they are hungry and fear being in the house by themselves, when asked where their mother is, the children say she went on a trip the day before. The neighbors take the children to their home and call law enforcement. 

Are children aged six and nine competent enough to care for themselves for an extended period without adult supervision? 

Current Patterns of Abuse 

Though anyone under the age of 18 can be a victim of child abuse, not all children are at equal risk of maltreatment. Pennsylvania statutes §6303 defines a child is an individual under 18 years of age. Young children are at the greatest risk, largely because they have limited verbal abilities to ask for help or tell someone what is going on. Children under 12 months of age are at the highest risk, with 45.6% being the victim of some form of abuse or neglect.  

Abuse can take many forms as well, with neglect being the most common form of child abuse nationally at 76% of affected children. Physical abuse accounts of 16% of cases, sexual abuse is 10.1%, and psychological/emotional is 6.4% (1). Many children also experience more than one type of abuse.  

Tragically, abuse and neglect are sometimes lethal, with nearly 1,820 children dying from maltreatment in 2021. A staggering 66.2% of those children were under the age of 3 (1).  

Child abuse occurs in homes of all races, socioeconomic statuses, educational levels, and religions. Being a victim of abuse has the potential for lifelong consequences for children, increasing their risk of teen pregnancy, drug and alcohol abuse, criminal activity, and even incarceration as an adult. About 30% of the time, abused children enter a cycle of abuse and grow up to abuse their own children as well (1).  

Understanding who is most at risk can help healthcare professionals identify potential victims of abuse within the populations they serve. Early and accurate detection of maltreatment can not only remove a child from a dangerous situation, but it can also set them on a better trajectory for their future and even quite literally save their life.  

 

 

 

 

Child Welfare in the State of Pennsylvania 

In addition to understanding when and how to report abuse, healthcare professionals must be able to recognize when abuse might be occurring. The common signs vary by type of abuse and no two situations are likely to be the same, but there are common indicators that should be used to alert healthcare providers to potentially ominous situations.  

Definition of Child Abuse

Components, Categories, and Exclusionary Criteria of Child Abuse 

A clear understanding of who is involved in an abuse or neglect situation and what actions (or inactions) specifically qualify as abuse is necessary for mandated reporters like healthcare professionals.  

When considering a child abuse scenario, a child is anyone under the age of 18.  

A perpetrator is someone “who has committed child abuse as defined in this section.” 

The term includes only the following: 

  • A parent of the child. 
  • A spouse or former spouse of the child’s parent. 
  • A paramour or former paramour of the child’s parent. 
  • A person 14 years of age or older and responsible for the child’s welfare or having direct contact with children as an employee of a childcare services, a school, or through a program, activity, or service. 
  • An individual 14 years of age or older who resides in the same home as the child. 
  • An individual 18 years of age or older who do not reside in the same home as the child but is related within the third degree of consanguinity or affinity by birth or adoption to the child.  
  • An individual 18 years of age or older who engages a child in severe forms of trafficking in persons or sex trafficking, as those terms are defined under section 103 of the Trafficking Victims Protection Act of 2000. 

 

Only the following may be considered a perpetrator for failing to act, as provided in this section:  

  • A parent of the child. 
  • A spouse or former spouse of the child’s parent. 
  • A paramour or former paramour of the child’s parent. 
  • A person 18 years of age or older and responsible for the child’s welfare. 
  • A person 18 years of age or older who resides in the same home as the child. 

Please Note: 

  • Nothing under the PA CPSL requires a person who has reasonable cause to suspect a child is a victim of child abuse to identify the person responsible for the child abuse in order to make a report of suspected child abuse. 

The CPSL allows for school employees to be considered perpetrators under the definition provided for “person responsible for the child’s welfare” or person “having direct contact with children.”       

 

School employee: An individual who is employed by a school or who provides a program, activity, or service sponsored by a school. The term does not apply to administrative or other support personnel unless the administrative or other support personnel have direct contact with the children.  

Person responsible for the child’s welfare: A person who provides permanent or temporary care, supervision, mental health diagnosis or treatment, training or control of a child in lieu of parental care, supervision, and control. 

Direct contact: The care, supervision, guidance or control of children OR routine interaction with children.  

As mentioned previously, child abuse falls into four main categories: neglect, physical abuse, sexual abuse, and serious mental injury. Many different acts fall into each category, but in general, intentionally causing harm to a child in any of these ways or failing to care for a child in a way that prevents harm from occurring is considered abuse (2).  

Case Study 

Case study No. 2 – Please read the scenario below and take a moment to reflect and examine how this untimely tragedy could have been prevented. 

One of the most extreme cases of child abuse occurred in Indiana in 1965 to a child named Sylvia Likens. The child was 16 years old when she was placed in the care of a neighborhood woman named Gertrude due to her family experiencing financial instability at the time. During her time at Gertrude’s house, Sylvia suffered all sorts of abuse daily at her hand. She was beaten, humiliated, deprived of basic life necessities and even forced to undress in front of a group of neighborhood boys on one occasion. Gertrude eventually had Sylvia stop going to school. Throughout her experience, neighborhood children and some adults witnessed her abuse and never reported it to the authorities. School officials at the time failed to recognize the common indicators of abuse and sadly Sylvia eventually died, succumbing to injuries and serious physical neglect. Although extremely tragic, her case led to Indiana’s Mandated Reporter Law, with the aim of preventing such atrocities as what Sylvia had to experience from ever happening again. 

Were there opportunities for someone to report this abuse to the authorities? What types of abuse did Sylvia endure? 

Exclusions of Child Abuse  

An exclusion is determined when substantiating a report, not when making a report.  

Pennsylvania Child Protective Services Law states:  

Definitions (23 Pa.C.S. § 6303): 

  • Restatement of culpability – Conduct that causes injury or harm to a child or creates a risk of injury or harm to a child shall not be considered child abuse if there is no evidence that the person acted intentionally, knowingly or recklessly when causing the injury or harm to the child or creating a risk of injury or harm to the child. 
  • Child abuse exclusions — The term “child abuse” does not include any conduct for which an exclusion is provided in section 6304 of the PA CPSL (relating to exclusions from child abuse). 

Please Note: 

  • Nothing in the PA CPSL requires a person who has reasonable cause to suspect a child is a victim of child abuse to consider the exclusions from child abuse before making a report of suspected child abuse. 
  • Exclusions from child abuse are considered/determined by DHS or the investigating agency after receipt of a referral/report. 

Such exclusions under Pennsylvania Child Protective Services Law include:    

Environment Factors 

Environmental factors that may cause harm but are out of a caretaker’s control, like inadequate shelter, clothing, medical care, or financial instability that are beyond the control of the parent or person responsible for the child’s welfare with whom the child resides. This shall not apply to any childcare services as defined in this chapter, excluding an adoptive parent. 

Practice of Religious Beliefs (23 Pa.C.S. § 6304) 

“If, upon investigation, the county agency determines that a child has not been provided needed medical or surgical care because of sincerely held religious beliefs of the child’s parents or relative within the third degree of consanguinity and with whom the child resides – which beliefs are consistent with those of a bona fide religion” –  

  • The county agency shall closely monitor the child and the child’s family and shall seek court-ordered medical intervention when the lack of medical or surgical care threatens the child’s life or long-term health.  
  • All correspondence with the subject of the report and the records of the Department and the county agency shall not reference child abuse and shall acknowledge the religious basis for the child’s condition.  
  • The family shall be referred for GPS, if appropriate. 
  • This subsection shall not apply if the failure to provide needed medical or surgical care causes the death of the child.  
  • This subsection shall not apply to any childcare service as defined in this chapter, excluding an adoptive parent.  

Use of force for supervision, control, and safety purposes 

Subject to rights of parents. 

The use of reasonable force on or against a child by the child’s own parent or person responsible for the child’s welfare shall not be considered child abuse if any of the following conditions apply:  

  • The use of reasonable force constitutes incidental, minor, or reasonable physical contact with the child or other actions that are designed to maintain order and control.  
  • The use of reasonable force is necessary: 
  • to quell a disturbance or remove the child from the scene of a disturbance that threatens physical injury to persons or damage to property;  
  • to prevent the child from self-inflicted physical harm; 
  • for self-defense or the defense of another individual; or 
  • to obtain possession of weapons or other dangerous objects or controlled substances or paraphernalia that are on the child or within the control of the child. 

Rights of Parents 

Rights of parents – Nothing in the PA CPSL shall be construed to restrict the generally recognized existing rights of parents to use reasonable force on or against their children for the purposes of supervision, control, and discipline of their children. Such reasonable force shall not constitute child abuse. 

Participation in events that involve physical contact with child –  (23 Pa.C.S. § 6304) 

An individual participating in a practice or competition in an interscholastic sport, physical education, a recreational activity, or an extracurricular activity that involves physical contact with a child does not, in itself, constitute contact that is subject to the reporting requirements of the PA CPSL.” 

Child-on-child contact –(23 Pa.C.S. § 6304) 

“Harm or injury to a child that results from the act of another child shall not constitute child abuse unless the child who caused the harm or injury is a perpetrator as defined by the CPSL.” 

Notwithstanding the above, the following shall apply: 

  • Acts constituting any of the following crimes against a child shall be subject to the reporting requirements of the PA CPSL:  
  • Rape as defined in 18 Pa.C.S.§3121B.Involuntary deviate sexual intercourse as defined   in 18 Pa.C.S. §3123C. 
  • Sexual assault as defined in 18 Pa.C.S.§3124.1D. 
  • Aggravated indecent assault as defined in 18 Pa.C.S.§3125E. 
  • Indecent assault as defined in 18 Pa.C.S.§3126F. 
  • Indecent exposure as defined in 18 Pa.C.S.§3127. 
  • No child shall be deemed to be a perpetrator of child abuse based solely on physical or mental injuries caused to another child in the course of a dispute, fight, or scuffle entered into by mutual consent. 
  • A law enforcement official who receives a report of suspected child abuse is not required to make a report to DHS if the person allegedly responsible for the child abuse is a non-perpetrator child. 

Defensive Force 

Defensive force: Reasonable force for self-defense or the defense of another individual (relating to the use of force in self-protection) and (relating to the use of force for the protection of other persons), shall not be considered child abuse. 

Case Study 

Case Study No. 3 – please read the following scenario and answer the questions below: 

A three-year-old child is brought to the emergency department (ED) with fever, rash, sore throat, and worsening lethargy for six days. Upon arrival to the ED, she is limp and unresponsive, and the mother reports it has been nearly 24 hours since she was last awake. The family decided to take her to the hospital when she had a seizure at home an hour before. A history reveals that the family are Christian Scientists, and the child is unvaccinated and does not receive regular medical care as the family does not believe modern medicine is necessary or beneficial. The child is diagnosed with measles encephalitis and transferred to the pediatric intensive care unit (PICU), where she later dies. The PICU physician files a report with CPS.  

  • Do the religious beliefs of the parents exclude them from potential child abuse allegations? Yes/No 

Correct Answer  

No – in this case there has been serious physical neglect caused by the delay from seeking medical attention which has caused the death of the child. 

 

  • Is it the mandated reporter’s responsibility to determine if child abuse has occurred? Yes/No 

Correct Answer  

No – the mandated reporter only has a duty to report when they have reasonable belief that abuse may have occurred. The determination of whether child abuse has occurred will be made by CPS. 

Provision and Responsibilities for Reporting Suspected Child Abuse 

Persons Encouraged to Report 

Persons encouraged to report (23 Pa.C.S.§6312) 

While reporting suspected or known abuse should be a compulsion of anyone who encounters it, many people are considered persons encouraged to report and are encouraged to make reports when necessary, but not required by law. Persons encouraged to report may make an oral or written report of suspected child abuse or cause a report of suspected child abuse to be made to the Department, county agency, or law enforcement, if that person has reasonable cause to suspect that a child is a victim of abuse. Written reports must be submitted electronically. 

Hotline Number: 1-800-932-0313 

Child Welfare Portal 

Persons Required to Report: Healthcare Professionals 

Persons Required to Report (23 Pa.C.S.§6311) 

As a healthcare professional, you are considered a mandated reporter, meaning there are certain situations where you are required by law to make a report of suspected or confirmed abuse. 

  • “Reasonable cause to suspect” may be a determination you make based on your training/experience and all known circumstances – to include “who”, “what”, “when”, and “how””, observations (e.g., indicators of abuse or “red flags”, behavior/demeanor of the child(ren), behavior/demeanor of the adult(s), etc.), as well as familiarity with the individuals (e.g., family situation and relevant history or similar prior incidents, etc.). It is also important to recognize how your feelings and personal biases may influence your conclusions and actions. 
  • Some indicators may be more apparent than others depending on the type of abuse and/or depending on the child’s health, development, and well-being, as well as may be physically visible on the child’s body while other indicators may be present in the child’s behaviors. It is also worth acknowledging that some indicators may overlap and suggest a child is a victim of more than one type of child abuse.

Privileged/Confidential Communications 

Privileged/Confidential Communications (23 Pa.C.S. § 6311.1) 

Mandated reporters may encounter situations where they have a reasonable suspicion of abuse through several different circumstances; including contact with the child through their job, direct involvement in the supervision or caretaking of the child, another person discloses the knowledge of abuse that is occurring to the child, or another person discloses that they themselves have abused the child. The child is not required to make a claim of abuse or even talk to the mandated reporter about it. Situations that reveal potential abuse must be reported even if the information is disclosed within a confidential relationship and reporting such incidents does not violate confidentiality laws (9).  

*Confidential communications apply to member of clergy as well as communications made to an attorney.  

Case Study 

Case Study No. 4 – read the following scenario and answer the questions below: 

A four-month-old child is brought to the pediatric clinic for a diaper rash. Upon measuring his length and weight, the nurse notes that the child has grown in length since his last visit two months ago but has only gained 3 oz, dropping from the 40th percentile to 5th percentile, and is now considered “Failure to Thrive.” Other than the diaper rash, the child is clean, though thin, and the mother shows appropriate affection for him in the office. When the nurse comments on his lack of growth, the mother admits she is having a hard time affording formula and has been diluting it to make it last longer. The nurse provides education about properly mixing formulas and information for the local Women Infants and Children (W.I.C.) program so that she can receive supplemental formula. Then, as a mandated reporter, the nurse contacts the Department of Human Services (DHS) for the county to report the situation.  

  • Is there reasonable cause to suspect child abuse? Yes/No 

Correct Answer:  

Yes – failure to provide a child with the necessities of life can be considered neglect. Even though it is due to reported financial instability, the mandated reporter has a responsibility to report, and DHS will investigate further and make the determination if there is an exclusion or not. 

  • Is this a scenario which has a basis to report in which the nurse must report as a mandated reporter? Yes/No 

Correct Answer:  

Yes – nurses are considered mandated reporters. The nurse has encountered the child through the practice of their profession.  

  • Which of the following entities must the nurse notify of the suspected abuse? 
    • The child’s mother 
    • Supervisor of the pediatric clinic 
    • Law enforcement 
    • Department of Human Services 

Correct Answer: 

B and D – the nurse must notify DHS via the statewide toll-free telephone number and notify their supervisor or other designated person in the clinic in charge of following up with such cases. 

Human Trafficking 

Examples of severe forms of human trafficking include: 

Labor Trafficking 

Labor Trafficking is labor obtained by use of threat of serious harm, physical restraint, or abuse of legal process. An example of human trafficking is being forced to work for little or no pay in such a climate as a farm or a factory; domestic servitude in providing services within a household from 10-16 hours per day performing duties such as childcare, cooking, cleaning, yard work, and gardening.  

Another example would be the recruitment, harboring, transportation, provision, or obtaining a person for labor of services through force, fraud, or coercion for the subjection of involuntary servitude.  

  • Peonage: paying off debt through work 
  • Debt Bondage: debt slavery, bonded labor, or services for a debt or other obligation 
  • Slavery: a condition compared to that of a slave in respect of exhausting labor or restricted freedom 
Sex Trafficking 

Sex trafficking is another form of severe human trafficking. It occurs when a commercial sexual act is induced by force, fraud, or coercion, or in which the person induced to perform such an act is not 18 years of age.  

Defined, Sex trafficking: the recruitment, harboring, transportation, provision, obtaining, patronizing, or soliciting of a person for the purpose of a commercial sex act. 

A commercial sex act is defined as any sex act on account of anything of value is given to or received by any person.

  • In the foster care system 
  • Who identify as LGBTQ 
  • Who are homeless or runaway 
  • With disabilities 
  • With mental health and/or substance abuse disorders 
  • With a history of sexual abuse 
  • With a history of being involved in the welfare system 
  • Who identify as native or aboriginal 
  • With family dysfunction 

Victim identification or warning signs to look out for in these populations include, but not limited to:  

  • A youth that has been verified to be under 18 and is in any way involved in the commercial sex industry or has a record of prior arrest for prostitution or related charges. 
  • Has an explicitly sexual online profile. 
  • Excessive frequenting of internet chat rooms or classified sites. 
  • Depicts elements of sexual exploitation in drawing, poetry, or other modes of creative expression. 
  • Frequent or multiple sexually transmitted diseases or pregnancies.

  • Being in a controlling or dominating relationship. 
  • Not having control of own finances. 
  • Exhibit hyper-vigilance or paranoid behaviors. 
  • Express interest in or in relationships with adults or much older men/women. 

Substance Exposed Infants and Plans of Safe Care 

Notification of Substance Exposed Infants by Healthcare Providers and Plans of Safe Care 

According to Act 54, a healthcare provider shall immediately give notice to the department if the provider is involved in the delivery or care of a child under one year of age and the healthcare provider has determined based on professional practice that the child was born affected by substance use or withdrawal symptoms resulting from prenatal drug exposure or a fetal alcohol disorder.  

A health care provider is defined as: A licensed hospital or health care facility or person who is licensed, certified, or otherwise regulated to provide health care services under the laws of Pennsylvania, including a physician, podiatrist, optometrist, psychologist, physical therapist, certified nurse practitioner, registered nurse, nurse midwife, physician’s assistant, chiropractor, dentist, pharmacist, or an individual accredited or certified to provide behavioral health services. 

Notification to the department can be made to ChildLine electronically through the Child Welfare Portal or at 1-800-932-0313. 

This notification is for the purpose of assessing a child and the child’s family for a plan of safe care and may not constitute a child abuse report.  

After notification of a child born affected by substance use or withdrawal symptoms resulting from prenatal drug exposure or a fetal alcohol spectrum disorder: 

  • A multidisciplinary team meeting must be held prior to the child’s discharge from the healthcare facility. 
  • The meeting will inform an assessment of the needs of the child and the child’s parents and immediate caregivers to determine the most appropriate lead agency for developing, implementing, and monitoring a plan of safe care. 
  • The child’s parents and immediate caregivers must be engaged to identify the need for access to treatment for any substance use disorder or other physical or behavioral health condition that may impact the safety, early childhood development and well-being of the child. 
  • Depending upon the needs of the child and parent(s)/caregiver(s), ongoing involvement of the county agency may not be required. 

Reporting Process    

All reports, whether mandated or not, should be made immediately by contacting the Pennsylvania Department of Human Services through the ChildLine hotline.

  • Any other information required by Federal law or regulation. 
  • Any other information that DHS requires by regulation. 

Reporting procedure (23 Pa.C.S. § 6313) section (e) 

(e) Applicability of Mental Health Procedures Act Notwithstanding any other provision of law, a mandated reporter who makes a report of suspected child abuse or who makes a report of a crime against a child to law enforcement officials shall not be in violation of the act of July 9, 1976 (P.L.817, No.143), known as the Mental Health Procedures Act, by releasing information necessary to complete the report. 

Release of Confidential Information 

Release of information in confidential reports (23 Pa.C.S. § 6340) section (c) 

(c) Protecting identity – Except for reports under section 6340(a)(9) and (10) of the PA CPSL and in response to a law enforcement official investigating allegations of false reports under 18 Pa.C.S. § 4906.1 (relating to false reports of child abuse), the release of data by DHS, county, institution, school, facility, or agency or designated agent of the person in charge that would identify the person who made a report of suspected child abuse or who cooperated in a subsequent investigation is prohibited. Law enforcement officials shall treat all reporting sources as confidential informants. 

Confidentiality of reports (23 Pa.C.S. § 6339)  

Except as otherwise provided in subchapter C of the PA CPSL (relating to powers and duties of department) or by the Pennsylvania Rules of Juvenile Court Procedure, reports made pursuant to the PA CPSL, including, but not limited to, report summaries of child abuse and reports made pursuant to section 6313 (relating to reporting procedure) as well as any other information obtained, reports written, or photographs or X-rays taken concerning alleged instances of child abuse in the possession of DHS or a county agency shall be confidential. 

ChildLine receives the report and determines who is to respond dependent upon the information reported, such as the identity, if known, of the person who allegedly acted to abuse or harm a child.  

ChildLine will immediately transmit oral or electronic reports that they receive to the appropriate county agency and or law enforcement official: 

  • If a person identified falls under the definition of perpetrator, ChildLine would refer the report to the appropriate county agency for an investigation. 
  • If the person identified is not a perpetrator and the behavior reported includes a violation of a crime, ChildLine will refer the report to law enforcement officials. 
  • If a person identified falls under the definition of perpetrator and the behavior reported includes a criminal violation, ChildLine will refer the report to the appropriate county agency and law enforcement officials. 

If a report indicates that a child may need other protective services, ChildLine will refer the report to the proper county agency to assess the needs of the child and provide services, when appropriate. 

If a report was made by a mandated reporter, the department will notify the mandated reporter who made the report of DHS’s receipt of the results of the investigation. 

A child abuse investigation must be determined within 30 days whether the report is: 

  • founded, indicated, unfounded or pending. 
  • Any services provided, arranged for or to be provided by the county agency to protect the child. 

An investigation may take up to 60 days if there is a valid reason, such as when waiting for results from a medical report or from another evaluation. 

While mandated reporters are not able to remain anonymous, they are offered certain protections from legal action as long as the report was made in good faith. Mandated reporters are immune from litigation involving photographs taken during an investigation, medical exams performed, or backlash from family members or perpetrators in situations where abuse was or was not actually found to be occurring. Their names are also kept confidential unless the situation evolves to one where the reporter’s identity must be revealed, such as testifying in court (4).    

Immunity From Liability 

Immunity from liability (23 Pa.C.S. § 6318) section (a) 

(a) General rule – A person, hospital, institution, school, facility, agency, or agency employee acting in good faith shall have immunity from civil and criminal liability that might otherwise result from any of the following: 

  • Making a report of suspected child abuse or making a referral for general protective services, regardless of whether the report is required to be made under the PA CPSL. 
  • Cooperating or consulting with an investigation under the PA CPSL, including providing information to a child fatality or near-fatality review team. 
  • Testifying in a proceeding arising out of an instance of suspected child abuse or general protective services.

Immunity from liability (23 Pa.C.S. § 6318) section (c) 

(c) Presumption of good faith – For the purpose of any civil or criminal proceeding, the good faith of a person required to report suspected child abuse and of any person required to make a referral to law enforcement officers under the PA CPSL shall be presumed. 

Protection From Employment Discrimination 

Protection from employment discrimination (23 Pa.C.S. § 6320) section (a) 

(a) Basis for relief – A person may commence an action for appropriate relief if all of the following apply: 

  • The person is required to report suspected child abuse or encouraged to report suspected child abuse. 
  • The person acted in good faith in making or causing the report of suspected child abuse to be made. 
  • As a result of making the report of suspected child abuse, the person is discharged from employment or is discriminated against with respect to compensation, hire, tenure, terms, conditions, or privileges of employment.

(d) Statute of limitations – The statute of limitations for an offense under this section shall be either the statute of limitations for the crime committed against the minor child or five years, whichever is greater. 

Case Study 

Case Study No. 5 – please read the following scenario and answer the questions below: 

A pediatric nurse is off duty and supervising her nine-year-old child and a few peers swimming in her backyard. She notices that one of the other children has a large fading bruise on his back. She is friends with this child’s mother, Katie, and asks her what happened when she comes to pick the child up. Katie gets very quiet and then admits that the child’s father sometimes is very rough when he gets angry and had grabbed the child by the arm a few nights ago and then hit him. Katie states not to worry, that the father has agreed to go to anger management, and she is hoping it won’t happen anymore.   

 

  • Is the nurse in this scenario required to report? Yes/No 

Correct answer: 

Yes – even if the nurse is off duty, “A person makes a specific disclosure to the mandated reporter that an identifiable child is the victim of child abuse. This statement does not require you to be “on the clock.” 

  • What category of child abuse is presented in this scenario? 
    • Neglect 
    • Physical  
    • Sexual 
    • Mental 

Correct answer: 

B – physical abuse includes corporal punishment that leaves bruises and has the potential to injure the child. 

Adverse Childhood Experiences 

Adverse Childhood Experiences or ACE is an umbrella term to describe events that had a potentially traumatic impact and that occurred before the individual turned 18 (2). 

The Centers for Disease Control and Prevention (CDC) reports that approximately 64% of adults in the United States have experienced an ACE (2). These experiences can have long lasting effects on health, overall wellbeing, access to higher education, and job opportunities. The impact reaches far beyond just the individual. It can affect their family dynamics and can have societal implications. This is why preventing childhood abuse and promoting family stability needs to be a community effort and not just the responsibility of a select few. 

Community Strategies to Prevent ACE: 

  • Increasing opportunities for families to have financial stability. 
  • Providing education on how to prevent violence and how to approach these situations as a person required to report or person encouraged to report. 
  • Community youth activities. 
  • Early intervention. 
  • Affordable access to high quality childcare. 

Conclusion

Obviously, even one child being abused is too many. However, as community advocates, teachers, healthcare professionals, and others working on correcting and eliminating the societal conditions that lead to child abuse in the first place, it is important for nurses and other healthcare professionals to continue working diligently to identify potential victims of abuse and activate the system in place to help them as quickly and efficiently as possible. By having an ability to identify who is at risk, an understanding of the reporting system, and knowledge on what being a mandated reporter entails, nurses can play an active role in curtailing the number of children seriously harmed by these situations. Children are one of our most vulnerable populations because of their dependency on others to meet their many needs. Advocacy for their safety is one of the most important roles a nurse can take on.

 

Pennsylvania Pain Management and Identification of Addiction

Introduction   

Pain can vary according to the source and intensity, as well as an individual’s age, gender, culture, and interpretation by the individual. Unfortunately, everyone will eventually experience pain. The nurse's role is crucial in providing comprehensive patient care by evaluating and treating pain effectively.  

Pennsylvania allows a licensed and authorized advanced practice nurse to prescribe and monitor medications, including narcotics for pain management. The state requires mandatory completion of a course on safe narcotic prescription and identification of potential substance use disorder, which is discussed in this course.  

Pennsylvania Laws Regarding Safe Controlled Substance Prescriptions  

Pennsylvania state and federal laws govern the prescribing and monitoring of controlled substances including all narcotics. The Controlled Substances Act (CSA), administered by the Drug Enforcement Administration (DEA), regulates all aspects of controlled substance manufacturing, distribution, dispensing, prescribing and distribution. The DEA regulations offer healthcare providers specific guidelines regarding prescribing practices, record keeping practices and monitoring (39).  

At the federal level any prescriber of narcotics or scheduled drugs must apply for and be approved to be a prescriber, which includes physicians, nurse practitioners, and physician assistants. It is within the scope of practice for a nurse practitioner in the state of Pennsylvania to prescribe narcotics with an approved advanced practice license and prescribing authority.  

Pennsylvania developed its own Controlled Substance, Drug Device and Cosmetic Act to outline regulations surrounding the production, distribution and dispensing of controlled substances within the state. This law mandates requirements such as prescription writing, dispensing, and record-keeping. Pennsylvania has a Prescription Drug Monitoring Program (PDMP) to track the prescribing and dispensing of controlled substances to patients. Healthcare providers must check this database prior to prescribing them to patients.  

The Pennsylvania Department of Health may issue additional regulations related to controlled substances, prescribing practices, and monitoring. Healthcare providers administering narcotics must abide by federal and state laws regarding prescription issuance for legitimate medical purposes while keeping accurate records and meeting PDMP requirements.  

Healthcare providers in Pennsylvania must remain up to date with both federal and state regulations to ensure safe prescribing practices, compliance, and ensure patient and colleague communication regarding controlled substances such as narcotics. Regular review is key.

  1. For patients with both chronic pain and substance use disorder, how can you collaborate with the interdisciplinary medical team to provide comprehensive care? 
  2. How can you help a patient with SUD with re-occurring and chronic pain? 
  3. How can the integration of complementary and alternative therapies enhance the effectiveness of pain management for patients with substance use disorders? 

Incidence And Prevalence of Substance Use Disorders 

By conducting a careful pain assessment, nurses can gain an understanding of a patient's subjective pain perceptions as well as its severity, causes, and symptoms. Nurses may implement both non-pharmacologic and pharmaceutical interventions to manage pain appropriately.  

The role of the nurse practitioner is to formally diagnose and order treatment, so a thorough understanding of pain management and identification of addiction risk factors is crucial. For DEA-registered practitioners, care should be given when choosing which pharmacological interventions to utilize, to minimize risks for substance abuse disorders and achieve maximum pain relief.  

Uncontrolled pain or the development of substance use disorders can disrupt functional living and complicate comorbidities. Collaboration among members of the health care team and patients themselves is also key, including setting realistic goals for managing pain effectively and actively participating in their plan of care. 

Pain, including abdominal, head, throat, and back pain, continues to be the top four most common patient complaints seen in primary care (1). In efforts to address and treat pain, both pharmacological approaches are given by nurse practitioners.  

Unfortunately, a result of prescribed pain medications is the possibility of substance use disorders, which is a continued important issue in the United States. The opioid epidemic continues to be a serious public health concern. Assessing, diagnosing, treating pain, and identifying risk factors for substance use disorder are important topics for every nurse practitioner.  

The most common substance use disorders in the United States are (2):  

  • Alcohol use disorder (29.5 million) 
  • Cannabis use disorder (16.3 million) 
  • Methamphetamine use disorder (1.6 million) 
  • Opioid Use disorder (5.0 million) 
  • Tobacco use disorder (16 million)

Types of Pain  

Pain can be an ordinary response to illness or injury and doesn't typically require medical intervention. Pain may be divided into various categories depending on its onset and duration, including acute, chronic or breakthrough (3).  

Acute pain is experienced from within minutes of an injury up to several months afterwards. Chronic pain is experienced beyond six months and usually due to a continuous medical issue or condition. Breakthrough pain occurs when pain that was controlled with medication begins to be felt beyond the pharmacological properties of the pain medication. Pain is divided further into neuropathic, nociceptive, and radicular (36). 

 

Type of Pain 

Definition 

Acute 

Short-term from minutes to less than 6 months 

Chronic 

Continues beyond 6 months 

Neuropathic 

Damage to nerves felt as sharp, stabbing, burning. 

Nociceptive 

Damage to body tissues felt as sharp, achy, or burning. 

Radicular

Pain Assessment 

Pain is considered the fifth vital sign and provides significant information about a patient’s lived experience.  

In 1995, it was proposed by a practicing physician James Campbell that pain should be considered the fifth vital sign, which was later supported by the American Pain Society as a standard practice guideline (6). In addition to blood pressure, heart rate, respiratory rate, temperature, and pulse oximetry, a pain assessment provides information necessary for holistic care.  

A regular pain assessment allows nurses to manage patient discomfort more effectively by creating personalized plans of action to effectively address pain management needs. Prior to ordering or administrating pain medications, nurses must perform an in-depth pain evaluation that includes gathering data from various sources, including the patient’s medical history, chief complaint, and a physical exam. A follow-up is important to evaluate any therapeutic results of prescribed medication.  

 

Components of a Pain Assessment 

A systematic pain assessment is key to correctly identifying all the components of pain (7). 

  1. Assess risks for pain. For example, advanced age, cancer, anxiety, recent surgery/invasive procedures increase the likelihood of experiencing pain and discomfort. 
  2. Assess pain using an approved pain scale to create a baseline for the current pain level (which will be discussed later). Remember pain is subjective and influenced by age, gender, and cultural factors.  
  3. Identifying the pain source such as nociceptive, neuropathic, referred, somatic, visceral, or phantom pain. 
  4. Assess the type of pain (acute or chronic) and contributory factors.  
  5. Evaluate their past response to pharmacological interventions and analgesics, including any adverse reactions they experience.  
  6. The assessment should include physical, behavioral, and emotional signs of pain including confusion, diaphoresis, moaning, decreased activity levels, irritability, guarding, clenched teeth, muscle tension, depression, insomnia, confusion, diaphoresis, moaning, and grimacing.  

 

Pain Assessment Mnemonics 

Nurses often use three mnemonics to remember standardized questions for conducting a comprehensive pain assessment: 

  • COLDSPA 
  • OLDCARTES 
  • PQRSTU 

Each letter presents important questions to ask the patient about their pain.  

Nurses may ask any number of questions to obtain information for each category. Examples of each of these mnemonics can help the practitioner remember to ask important questions relevant to pain.  

 

COLDSPA 

Questions to ask: 

C: Character 

What does the pain feel like? 

Does it feel like burning, stabbing, aching, dull, throbbing, etc.? 

O: Onset 

When did the pain start? 

What were you doing when the pain started? 

L: Location 

Where do you feel the pain?  

Does it move around or radiate elsewhere? 

Can you point to where it hurts? 

D: Duration 

How long has the pain lasted? 

Is the pain constant or does it come and go? 

If the pain is intermittent, when does it occur? 

S: Severity 

How would you rate your pain on a scale of 0 to 10, with “0” being no pain and “10” being the worst pain you’ve ever experienced? 

How much does it bother you? 

P: Pattern 

What makes your pain feel better? 

What makes your pain worse? 

Does the pain increase with movement, certain positions, activity, or eating? 

A: Associated Factors 

What do you think is causing the pain? 

What other symptoms occur with the pain? 

How does the pain affect you? 

 

The “OLDCARTES” mnemonic consists of the letter of each category of questions to ask. 

  • O: Onset 
  • L: Location 
  • D: Duration 
  • C: Characteristics 
  • A: Aggravating factors 
  • R: Radiating 
  • T: Treatment 
  • E: Effect 
  • S: Severity 

The “PQRSTU” mnemonic also helps the clinician to ask about components of pain.   

  • P: Provocative/Palliative 
  • Q: Quality/Quantity 
  • R: Region/Radiation 
  • S: Severity 
  • T: Timing/Treatment 
  • U: Understanding 

 

Regardless of the pain assessment framework utilized, it is critical that open-ended questions allow patients to describe the pain in their own words. Closed-ended questions result in either yes/no responses or fail to capture an accurate account of the patient’s pain.  

It is also vitally important for the nurse to follow-up on initial responses by asking clarifying questions so they can create and implement an individualized pain treatment plan to address all aspects of pain. In completing a pain assessment with patients, the nurse practitioner gains better trust with the patient, which can result in better patient adherence to prescribed treatment.  

 

Pain is Subjective 

Given that everyone responds differently, each person's experience of pain will vary widely, even for stimuli with similar properties. For instance, some may feel considerable discomfort after receiving injections while others experience none, which means consequently we must treat pain according to whatever the individual claims it to be.  

Due to this completely subjective nature of describing pain, the evaluation of the response to pain medication is also subjective. Clinicians must recognize the biological, psychological, and social factors that affect the perception of pain as shown in the following table.  

 

Biological Factors

Pain Scales 

At the core of any pain assessment is determining the intensity. As pain cannot be objectively tested to pinpoint an individual's sensations, providers use pain scales as tools for objectively understanding each patient's discomfort and setting realistic pain goals. Nurses have access to numerous standardized pain scales.  

A popular one is numerical, in which patients rate their discomfort between zero and 10, with zero being no pain and 10 being the worst pain ever experienced. While simple and user-friendly, numerical pain scale cannot be used by children or other populations who cannot accurately quantify pain, therefore alternative pain scales such as FACES scale, FLACC scale comfort behavioral scale or PAINAD scale may be used. 

The FACES scale is a visual assessment tool for children and other people who cannot use numeric scales. When using it with children or others who cannot describe numbers accurately, explain to the patient that each face represents either no pain, some discomfort, or intense distress. For instance: Face 0 doesn't hurt at all while Faces 2-6 hurts just slightly more, while Face 8 hurts even further before reaching 10, which represents extreme suffering. Ask the individual which of those depictions best represents their discomfort.

The FLACC scale is used to assess pain in children aged two months to seven years and those unable to verbalize. It comprises five criteria such as face, legs, activity, cry, and consolability. Care providers assign each criteria a score between zero and two upon observation of their patient and then combine all five scores together into an overall pain score between zero (no pain) and 10 (10 severe) (8).  

The Pain Assessment in Advanced Dementia (PAINAD) Scale is used to assess pain in patients with advanced dementia (9). This scale has five criteria including breathing independent of vocalization, negative vocalization, facial expression, body language, and consolability.  

Like the FLACC scale, each of the five criteria are assigned a score of 0, 1, or 2. The provider observes the patient, assigns a score for each criterion, and adds the scores. The total pain score will be between 0 and 10, with 0 being no pain and 10 being severe pain. Like FLACC, the PAINAD scale is simple, valid, and reliable, but it may not always result in the most accurate pain assessment, as it requires the nurse to calculate the score based upon observed patient behaviors rather than the patient’s subjective pain rating.

  2. What pain scales do you commonly use in assessing pain and are they appropriate for the age, gender, and verbal skills of the patient?  
  3. What other questions should you ask about a patient’s tolerance of pain and how they have handled pain in the past? 

Cultural Influence on Pain 

Culture plays an intricate role in how individuals express physical and emotional discomfort. Some cultures, such as those found in East Asia, place strong value on self-discipline and control and may choose not to show any emotions when in pain.  

Middle Eastern and Mediterranean societies emphasize open expressions of emotion and may easily express and verbalize their sensations of pain (10).  

Although culture may impact pain levels differently for each patient, nurses must understand its impact before creating an individual plan that best meets each person's specific needs. 

 

Pain Assessment on Special Populations 

The elderly, children, individuals who speak English as a second language, deaf, mute, limited English training, and people from different countries may require additional patience while completing a pain assessment.  

Chronic pain can be related to depression, anxiety, and sleep disturbances, which can complicate a clear report of pain. Using a multimodal approach for a pain assessment, a physical exam, and the pain scales identified above can be helpful.  

 

Reassessment After Intervention  

Pain must always be assessed again following implementation of an intervention to determine its effectiveness in relieving symptoms. Oral medications should be assessed within 1 hour while intravenous treatments within 15-30 minutes, and per facility protocol (40). 

For a primary care provider in an office clinic, reassessing pain should use the same pain scale used during initial assessment at the next visit. If their discomfort has not decreased to meet their established goal level, further interventions will be needed.  

Interventions may involve medications and/or nonpharmacological modalities like heat, ice, music therapy and repositioning to achieve the patient's ideal pain goal (41). Intervention and reassessments must continue until this goal has been attained. All reassessments and interventions must be documented in their medical record. 

 

Pain Management Care Plan  

In developing care plans for pain, nurse practitioners should provide a tailored approach to address each patient's unique pain management needs. Beginning with an in-depth evaluation, the nurse practitioner gathers information regarding medical history, current pain symptoms, functional status, psychosocial factors, and desired goals for treatment.  

Based on their evaluation, nurse practitioners collaborate with patients to set realistic expectations and goals for pain management care plans that integrate pharmaceutical interventions along with nonpharmacological interventions.  

Pharmacological interventions include using analgesic medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), opioids and any adjuvant medicines such as antidepressants or anticonvulsants as well as topical agents to relieve discomfort (42).  

Nurse practitioners carefully consider all risks and benefits when prescribing medications to their patients, tailoring individualized plans to optimize pain relief while mitigating adverse side effects as well as risks related to opioid misuse or addiction.  

Non-pharmacological interventions also play a vital part in pain management. These may include physical therapy, occupational therapy, acupuncture, and massage therapy as well as cognitive-behavioral therapy (CBT), relaxation techniques and mindfulness-based interventions.  

Nurse practitioners work collaboratively with other healthcare professionals such as physical therapists, psychologists, and pain specialists to coordinate and integrate interventions into a patient's care plan. Education and self-management strategies also play a pivotal role in pain management plans. Nurse practitioners provide patients with education about their pain condition, its causes, and possible solutions.  

Patients can become actively engaged in their care by learning self-management techniques such as pacing activities, maintaining proper posture, using heat or cold therapy, and practicing stress reduction methods.  

Additionally, patients receive guidance regarding medication adherence, potential side effects and the significance of regular follow up appointments to monitor progress. Furthermore, their pain management care plan incorporates strategies designed to address any psychosocial factors which might impact pain for an improved experience and treatment outcome. Screening may include depression, anxiety, sleep disturbances, substance use disorders and any additional coexisting conditions. 

Referrals may be made to mental health professionals, social workers, or support groups as a source of additional assistance and resources for the patient. Reassessment and monitoring should form integral parts of any pain management care plan. Nurse practitioners collaborate closely with patients to monitor pain levels, functional status, effectiveness of medication treatment plans and any adverse side effects. Treatment plans may be altered accordingly as needed based on response to therapy, changes to condition or evolving goals of care.

Pharmacological Pain Management 

Pain medications are divided into two main groups, including analgesics and adjuvants. Analgesics are used to prevent or treat pain and can further be classified as opioids or nonopioids; the classification is based on whether their original source is from poppy plants, known as opioids (42).  

Nonopioids include medications not classified as opioids while adjuvants contain medication with both independent analgesic properties as well as additive properties when taken together with opioids. 

When taking analgesics, it is wise to start with those having minimal side effects in a smaller dose and using minimally invasive approaches. 

Developed by the World Health Organization, the following graphic demonstrates the stair-step ladder approach to guide the advancement of pain medication.

Image Source: https://www.researchgate.net/figure/The-World-Health-Organization-WHO-pain-ladder-modified-for-Acute-Pain-Management-a_fig1_340312749 

 

Originally created to assist cancer patients, the pain ladder model can now be applied to all forms of discomfort. Nonopioids should generally be employed first in managing pain and if persistent or increasing discomfort continues then opioids or adjunct therapies should be added alongside nonopioids as appropriate (43).  

For severe, short-term pain that's expected to diminish gradually over time however, opioids, nonopioids and adjunct therapies might initially all be given before gradually withdrawing their presence so only nonopioids remain. 

Analgesic Medications  

Analgesic medications (nonopioids and opioids) are used to alleviate or manage pain. Nonopioids tend to work best at managing mild-to-moderate discomfort in most cases and are well tolerated by most users. Examples of such analgesics include acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDS).  

 

Acetaminophen 

Acetaminophen is a non-narcotic analgesic and fever reducer. It is available by prescription or over the counter (OTC). Acetaminophen (the active ingredient found in Tylenol) can help relieve mild pain in all age groups and is generally safe. As it can be administered orally, sublingually, or intravenously, it could also provide an ideal choice for people unable to take oral medications.  

The pharmacokinetics and mechanism of action of acetaminophen include the quick absorption from the gastrointestinal tract within 30-60 minutes. Delays of absorption to peak concentration in the circulatory system can be due to food in the stomach. It is then metabolized by the liver via the three main hepatic pathways including glucuronidation, sulfation, and CYP450 oxidation (44). The half-life is approximately 4 hours, however with hepatic injury or overdose the blood peak level can be accelerated to 2 hours.  

In patients suffering from liver failure, it should be used with caution as one potential adverse side effect could be hepatotoxicity. Therefore, it is crucial that daily dosage be closely monitored (12). Millions of people use over the counter (OTC) pain relievers every day to treat minor aches and pains.  

Usually, these medicines are safe and effective, but they can be dangerous and even deadly when they are not taken as directed (11). Acetaminophen, also called paracetamol in many other countries, is sold by many names including Tylenol, Panadol, Ofirmev, Acephn, and Mapap. 

It is used effectively for fever, muscle pain, neck pain, plantar fasciitis, sciatica and common body aches and pains.  It is abbreviated as APAP for acetyl-para-aminophenol, which is the chemical name and is known by 28 band names in the United States (12).  

It is very commonly used in combination drugs for pain as a nonnarcotic analgesic and known as Excedrin, Goody’s Body Pain, Saleto, Exaprin, Levacet, Painaid, Apadaz, Rhinocaps, Staflex, and included in over-the-counter medications for acute cold symptoms, respiratory conditions, and headaches (43) 

In addition, it is a component of some narcotic prescriptions. Acetaminophen can be used as a sole medication or as an active ingredient in many OTC and prescription medicines. Acetaminophen is generally safe at recommended doses, but if taken in larger dosages or frequency, it can cause serious and even fatal liver damage. In fact, acetaminophen poisoning is a leading cause of liver failure in this country (13). 

 

Safety guidelines include:  

  • Older adults: limit to no more than 3,200 mg in 24 hours.  
  • Healthy young adults: can take no more than 4,000 mg.  
  • Alcoholism: should limit themselves to no more than 2,000 mg daily.  

 

Add all sources of acetaminophen into daily totals, including amounts found in combination medicines such as Percocet 5/325, which contains 5mg Oxycodone and 325 mg Acetaminophen. One Percocet 325 mg tablet should count toward the total daily acetaminophen dosage and should be included when prescribing individual dosages to avoid too close an administration of multiple medicines at once.  

As an illustration, if 500 mg of acetaminophen is prescribed every four hours to combat fever while 5/325 Percocet is intended as pain reliever, both medications should not be given together within four hours as it would increase intake significantly and cause too much acetaminophen.   

 

NSAIDs 

Nonsteroidal anti-inflammatories (NSAIDs) are nonprescription medicines prescribed to relieve mild to moderate discomfort and may also be combined with opioids for treating severe pain. The pharmacokinetics of NSAIDS is based on the absorption, distribution, metabolism, and elimination of the drug as all oral medications. NSAIDS inhibit both COX-1 and COX-2 enzymes and play a role in prostaglandin mediated pain from inflammation (45).  

Although they offer more gastrointestinal protection than aspirin, they do have cardio-nephrotoxic adverse effects. Due to the inhibition of prostaglandins and thromboxane, the desired actions are anti-inflammatory, antipyretic, and analgesic.  

Common examples of NSAIDs are Ibuprofen, Naproxen and Ketorolac. Ibuprofen should be taken every 6-8 hours for adults aged six months or over. Naproxen can be taken 2-3 times per day and provides longer-acting pain relief than Ibuprofen does. Ketorolac may be taken temporarily (up to five days) in cases of moderate-to-severe adult pain relief. Aspirin is often the last line of nonopioids before turning to opioids and may help treat breakthrough pain for patients already taking opioids.  

Side effects from taking an NSAID drug could include dyspepsia, nausea, and vomiting. To minimize risk, NSAIDs should always be taken with food. Long term or high dose use also increases risks such as heart attack, stroke, and heart failure; and must be prescribed carefully for people over 60 or those with liver or renal problems. One notable exception is aspirin, which when taken in low doses may reduce the risk of another heart attack in people who have already had one. NSAIDs may cause gastrointestinal bleeding when combined with warfarin or corticosteroids.

Opioids  

Opioids include codeine, fentanyl, hydrocodone, meperidine, hydromorphone, methadone, morphine, oxycodone, and heroin. Drugs from the class of opioids are powerful analgesics and used for pain management. From 2000 to 2021, more than one million people in the United States died from opioid drug overdoses and over 80,000 died from opioids in 2021 (14).  

Opioids are categorized as schedule 1 or 2 drugs by the Drug Enforcement Agency (DEA). A schedule 2 drug, such as morphine, means that although it has been approved for medical treatment as an analgesic, it has high potential for strong psychological and physiological dependence.  

It has been used for over 100 years as an analgesic. Heroin is made by taking morphine, from the opium plant, and adding a chemical reagent that makes it more potent and potentially dangerous. Heroin is a schedule 1 drug and is not approved for any medical use as it is highly addictive.  

So how did we get to this point of millions of Americans using and abusing opioids? The documented use of opioids began as early as the 3400 BC in Mesopotamia, which they called the “joy plant.” Opium was used for every medical malady from diarrhea, cholera, rheumatism, fatigue and even diabetes by early Egyptians.  

Opium was then regularly traded by Turkish and Arab traders in the 6th century. Opioid use became much more available in the early 1700’s as the British refined the production from the Asian poppy plant grown in the British providence of India and sold in China. What became helpful as analgesia quickly became popular for treating every malady and even used as entertainment in historical records of opium parties (15). British ships filled 1,000 chests of opium into China in the 1760’s and ships gradually increased it to 4,000 chests in 1800 to eventually 40,000 chests in 1838. Opium was so popular in China and the desire for porcelain, silk and tea was equally in demand in the West, so the trading continued.  

Because of its powerful addicting properties to the Chinese citizens, the Chinese emperor Yongzheng (1722-1735) eventually prohibited the sale and smoking of opium, which resulted in two infamous Opium Wars (Britannica). Opium trading eventually became more regulated and slowed during the communist reign in China. Unfortunately, the opium trading continued with new players such as tropical growers and illegal importers from Central and South America to the United States. 

In the late 1800’s Bayer created heroin and misuse was rampant causing regulations and taxes to thwart its use (15). Then after WWII and Vietnam another wave of use and abuse crossed America with the resultant reflex to regulate and tax its use. The war on drugs has continued.  

Opioids are prescribed to manage moderate to severe pain by blocking the neurotransmitter that sends pain signals. Opioids can be administered via oral, intramuscular, intravenous, subcutaneous rectal or transdermal means. Oral opioids such as codeine, hydrocodone and oxycodone are typically prescribed to manage moderate pain.  

Stronger opioids like fentanyl hydromorphone or morphine may be utilized if necessary for more intense discomfort. Morphine is often prescribed for cancer and end-of-life pain treatment because its impact does not reach a plateau point where increasing dosage won't have any more of an impact.

Pharmacokinetics and Pharmacodynamics of Opioids  

Analgesics are a drug class that helps relieve the body from the sensation of pain by blocking chemicals in the neurons throughout the brain that sense pain. Neurons send messages of stimuli from the body to the brain and include different types of neurons that sense different things in the body from temperature, pressure, and even blood acidity and alkalinity.  

The metabolism of opioids occurs through the Cytochrome (CYP-450 enzymes), which blocks the nerves from relaying messages to the brain (46).  

Nociceptors, the nerve receptors for pain, send messages from noxious stimuli to the brain from the skin, walls of organs, and deep within the body such as muscles that something is hurting the tissues. Nociceptors send messages such as pressure, sharp objects, noxious smells, tastes and pain and the brain interprets those for immediate response to protect the body.  

There are several neurotransmitters involved in pain signals, but the main ones are glutamine and substance P. When noxious stimuli trigger the primary neuron through the skin or muscle, the message is relayed by a secondary neuron to the spinal cord’s dorsal root ganglion towards the brain for interpretation.  

These chemicals are relayed to the thalamus in the brain and then onto the limbic system for an emotional response. Ideally the message to the limbic area of the brain promotes learning to avoid the cause of the noxious substance in the future. Opioids inhibit pain signals at multiple areas in this pathway. 

Opioids affect the brain, spinal cord, and even the peripheral nervous system. Opioids work on both directions of messages in the nervous system including the ascending pathways in the spinal cord, which are inhibited and the descending pathways, which block inflammatory responses to noxious stimuli. In the brain, opioids cause sedation and decrease the emotional response to pain.  

Heroin, like morphine, passes through the liver and then is released back into the blood where it passes the blood-brain barriers. Heroin is then converted to morphine where it connects with mu receptors, but only faster and heroin is three times more potent than morphine (18).  

Opioid receptors are found on both the primary and secondary neurons and when an opioid binds to these receptors no other pain signals are sent up to the brain, making opioids very effective against pain. Naturally these endogenous analgesic receptors include human endorphins, which comes from the name endogenous morphine.  

Our bodies have three receptors called mu, kappa and delta which can be activated by opioid agonists like morphine, hydrocodone, or heroin. When mu receptors are activated, dopamine, a natural brain chemical, is also increased, which is the brain’s chemical for pleasure. Pleasurable feelings are inherently worth repeating, which drives the user to repeat the drug use (18).  

 

Short term sensations of opioids include the following:  

  • Warmth sensation through skin and body 
  • A feeling of heaviness in arms and legs 
  • Pain relief 
  • Dry mouth 
  • Itchiness 
  • Possible dry mouth 
  • Drowsiness 
  • Slow heart functioning. 
  • Slow breathing. 
  • Relaxation 
  • Sense of well being 

 

Opioid agonists come with additional noxious side effects. When a kappa receptor is stimulated it can also produce hallucinations, anxiety, and restlessness. The Delta and mu receptors can cause respiratory depression because as the midbrain is stimulated it suppresses the body’s ability to detect carbon dioxide levels in the body, which is the main stimulus for breathing. Other negative side effects include constipation, sedation, nausea, dizziness, urinary retention, and tolerance.  

Tolerance is the requirement of the body to need increased amounts of the drug to reach its desired effects, which is why opioids can become addictive as the person requires more of the drug to achieve the desired pain relief (18). The key ingredient in opium is morphine, which began to be produced formally by the pharmaceutical company Merck. It was also discovered that when administered by IV, morphine is 3 times more potent than administered by other methods such as smoking or snorting.   

Long term use of opioids has been shown to cause the deterioration of the brain’s white matter and include long term effects of insomnia, chronic constipation, sexual dysfunction, irregular menstrual cycles in women, kidney disease and physical damage as a result of the administration technique such as snorting, smoking or IV drug use.  

Although cocaine and morphine both have effects on the neurotransmitter dopamine, they work in different ways. Whereas the opioids increasing dopamine stimulation, cocaine blocks the reuptake of existing dopamine and makes it last longer producing a longer state of pleasure. Both opioids and cocaine drugs influence the brain’s interpretation of the pleasure drive reinforcing the drive for repeated behavior to get the drug.  

 

In addition to the short-term withdrawal symptoms, long term opioid use causes:  

  • Decreased ability in decision making. 
  • Decreased ability for self-reflection and discipline. 
  • Decreased ability to effectively respond to stress. 

 

Opioids can be effective pain relievers yet can become highly addictive if used improperly. Of the potential adverse reactions associated with opioid use, respiratory depression is the most serious. Those taking opioids must monitor for decreased respiratory rate, oxygen saturation, and heart rate after receiving them. Those taking opioids for the first time or receiving increased doses, taking concurrent benzodiazepine use such as alcohol consumption or other sedatives may experience a more significant respiratory depression.  

Treating opioid-induced respiratory depression requires treatment with Naloxone, which binds the mu receptors that opioids act on. Naloxone comes in a variety of preparations, including nasal spray, auto-injectors, and injectables.

  3. What should be included in patient education play for those individuals prescribed opioids for pain management? 

The Pain of Opioids 

The Center of Disease Control has declared the overuse and abuse of opioids an epidemic (14). Ninety-one (91) Americans die every day from an opioid overdose (14). The US consumes 99% of all the world’s hydrocodone, 80% of the world’s oxycodone, and 65% of the world’s hydromorphone prescription opiate supply. 25% of all workers’ compensation costs relate to opioids and $56 billion/year is spent on opioid abuse costs. Trends of opioid overdose related deaths have increased 5.5% annually from 6 deaths per 100,000 people in the US in 1999 to 16.3 in 2015.  

In adults aged 45-54 the death rate from drug overdose was the highest of all age populations showing a constant trend upward of 10% annual increase in abuse and deaths (16). Clearly, America has an opioid epidemic that is claiming lives and lifestyles. Additional statistics, not as easily identified but very real, include lost productive work hours and loss of meaningful lives, families, and marriages due to opioid abuse (17). 

Patients taking opioids must also be monitored for less severe side effects, such as constipation, nausea and vomiting, urinary retention, and itching. Opioids slow peristalsis and increase reabsorption of fluid into the large intestines, thereby slowing the passing of stool and removing the fluid from the stool so that it becomes concrete-like. It is important for the nurse to assess bowel functioning and encourage fluid and fiber intake and ambulation throughout the course of opioid treatments.  

The provider can prescribe a bowel management program that includes a stool softener (such as docusate) and a stimulant laxative (such as sennoside, bisacodyl, or milk of magnesia). Should nausea and vomiting occur, antiemetics (such as prochlorperazine or ondansetron) may be prescribed. Antihistamines (such as diphenhydramine) may be prescribed for subsequent itching; however, they may cause drowsiness and exacerbate the potential for opioid-induced respiratory depression. 

Fentanyl 

The Centers of Disease Control has estimated that over 20,000 Americans died from fentanyl overdose in 2016 and that rate continues to climb in America. Fentanyl production in China has surged with the high demand for it in America and it has been called the new nuclear narcotic in the Opium War Against America (19).  

 

Names of Fentanyl 

Prescription Street Names 

  • Abstral: China Girl or China Town 
  • Actiq: Dance Fever 
  • Duragesic: Friend 
  • Fentora: Goodfellas 
  • Instanyl: Great Bear 
  • Lazandal: He-Man 
  • Sublimaze: Jackpot, King Ivory, Murder 8, Tango and Cash, Per-a-Pop (berry flavored Fentanyl lozenge)  

One danger of fentanyl use is when fentanyl is mixed in with street drugs such as heroin and the user is unaware of what they are receiving. The quantity of fentanyl in street products also varies widely and can become quickly fatal as doses exceed what would have been carefully prescribed. Illegal street use without guidance, monitoring and education have created the dangerous opioid epidemic. The fully synthetic drugs such as fentanyl are much more potent and have the higher potential for abuse and death (19).  

As an analgesic, fentanyl is 100 more potent than morphine and 50 times more potent than heroin (20). Ohio forensic testing in 2017 revealed 99% of their narcotic overdose deaths were fentanyl related and often due to combinations of synthetic fentanyl products including 25 fentanyl analogs such as acryl fentanyl, nor fentanyl and furanyl fentanyl.  

The state also determined that males accounted for 64% of overdose deaths and 92% were white (21). Over half of the deaths in Ohio were in persons aged 25-44 years (22).  Trends continue to rise and causes point to the increased prescriptions of opioids for chronic pain and the availability of these drugs in non-prescription form.  

 

Route and Administration of Fentanyl 

Opioids can be administered by FDA approval through the subcutaneous, intramuscular, and intravenous and oral routes but due to variations in first-pass liver metabolism there are variations of response by users. Non-prescription drug users often speed the delivery by nasal and intravenous administration.  

The potency of fentanyl and carfentanil have been demonstrated by the rapid deleterious effects on police officers who have come in contact with the powder through their skin during drug investigations and raids. One police officer overdosed just by brushing power off his uniform with his hand (23). 

Subcutaneous fentanyl is commonly used to address chronic local pain, such as in a transdermal fentanyl patch that has a slow-release action. When fentanyl is delivered through more rapid routes such as IV or intranasal, the response is much quicker and therefore potentially fatal.  

Fentanyl is usually administered by injection or topical patch in the hospital setting. It may be prescribed through the intradermal route for chronic pain and is classically used for chronic lower back pain. 

 

Contraindications 

It should not be used by someone who is allergic to the drug, has any type of breathing problem, a history of head or brain injury, liver or kidney disease, slow heart rhythms, concomitant use of sedatives like Valium or if a MAO inhibitor has been used in the recent 14 days or the client is already taking another narcotic.  

There are no adequate studies to confirm safety or danger in pregnancy or breastfeeding so providers must be notified, and careful clinical decision making must be considered to weigh benefits from any possible damage to infants and mothers as it is a Category C claiming risk cannot be ruled out (24).

Patient Education and Support 

Online and face-to-face support groups are available to help with effective and appropriate use of fentanyl. Often the only information provided is about the serious opioid epidemic and potential risk for addiction and abuse, however when used properly and within the clear instructions given by a medical provider who is monitoring for adverse reactions, it can be a helpful option for people in very real chronic pain.  

Using any medications as directed is important because the route has been chosen for a specific reason. Unfortunately, a dangerous practice of chewing on a transdermal patch can speed up the delivery of the drug and create addiction and possibly respiratory depression or death. Mental and physical dependence can still occur even at prescribed doses so patients must be carefully monitored.  

Supporting patients in their quest for relief from pain and judgement is extremely important. In the national conversation about opioid abuse, patients who have a real need for chronic pain continue to suffer as physicians are attempting to prescribe less, and pharmacies are blocking repetitive refilling of narcotics.  

The dialog for effective pain management and effective systems to prevent opioid abuse must continue in creative, non-judgmental, and respectful ways. Encouraging support groups who can speak freely about issues and concerns can be helpful. Not all people who use fentanyl are drug addicts and should not be treated as such.  

The pain blocking effects of intradermal fentanyl often takes from 12-48 hours and often up to 72 hours and may require a breakthrough alternative to pain relief until the full effect is in action. Titrating carefully for pain relief is required based on individualized patient needs. Variations in the need for higher dosages depends on the location of a transdermal patch, the quantity of fat on the body area and dryness of the skin it is applied to.  

All patients should be taught to avoid alcohol consumption if using fentanyl. Patients also need to be aware that the narcotic may remain in the blood stream for up to three days and can be in hair and urine. Drug testing for abuse or employer requirements is most commonly done on hair and urine.

Patient-Controlled Analgesia 

Patient-controlled analgesia (PCA) allows a patient to self-administer opioid medications such as morphine, hydromorphone, and fentanyl without requiring a nurse to give each injection, by using an automatic pump programmed with their dosage amount and rate/volume settings (37). A locked computerized pump connects directly to their IV line where medication syringes can be safely locked inside ready for an infusion at scheduled rates/volume settings; its programming ensures medication infusion occurs at its intended rate/volume setting without exceeding prescribed amounts. 

Doses of medication can be self-administered on an as-needed basis by pressing a button. Patients may give themselves doses according to an adjustable schedule that includes preset interval times and dose limits per hour, up to four in total per hour limit. If these criteria are fulfilled, the PCA button illuminates to alert patients that doses can be administered when needed. Even when not illuminated, pressing it still delivers medication.  

PCAs may only be used for patients who are alert, oriented, and can independently press the button. Because small doses of opioids are administered frequently, it is important to monitor patients for oversedation and respiratory depression. To reduce the risk of these adverse events, the patient and all caregivers should understand that no one should press the PCA button except the patient. Nurses should also ensure that the PCA button is easily within the patient’s reach, as patients on PCAs are at a high risk for falling. 

Given the potential risk associated with PCA medication errors, both incoming and outgoing nurses should independently double check to verify correct drug, concentration, and dose (loading dose, PCA demand dose, continuous dose), lockout interval and 4-hour limit settings of their pump settings (37). When providing bonuses or changing any settings or replacing medication syringes two nurses will always be needed to verify results accurately. 

As part of their PCA treatment, it is vital that patients carefully monitor their vital signs to detect possible indicators of respiratory depression such as decreased respiratory rate, oxygen saturation levels or heart rate. Nurses must follow organizational protocols when administering PCA medications - usually including taking baseline vital signs prior to commencing administration, for an extended period post administration and then every two hours for its duration.  

 

Co-Analgesic Medications 

Co-analgesics, commonly referred to as adjuvants, are medications with analgesic properties; however, their primary purpose is not pain relief. For instance, antidepressants are usually taken for treating depression but may also help manage chronic pain symptoms, like sleep issues and muscle spasms. Anxiolytics may help relieve anxiety symptoms but could potentially also treat chronic pain-related anxiety as well as relax muscles. Anticonvulsants used for seizures also block pain receptors and help with providing relief from certain forms of neuropathic pain while corticosteroids reduce inflammation while simultaneously managing this kind of discomfort from injured nerves. 

Patient Education 

Prescribers have an obligation to educate patients appropriately on pharmacological pain interventions, in a culturally and linguistically sensitive manner. Drug education should help the patient comprehend the treatment plan, improve adherence to the treatment plan, alleviate fears while setting realistic expectations and discussing concerns openly, all to ultimately contribute to improved health, well-being, and patient outcomes. 

Education should start when treatment commences and continue throughout the duration of therapy. A personalized approach tailored specifically for each individual should include considering the primary language spoken by the patient as well as culture, age, cognitive function, and health literacy level.  

Simple language with clearly defined technical terms used along with open-ended questions as well as visual materials like demonstration videos/pictures or handouts may prove highly useful during education sessions. It is crucial not to wait until severe discomfort before seeking medication as once pain becomes extreme it becomes much harder to control and may require stronger medications.  

Nurses should help patients understand the typical progression of pain medication prescribed through the pain ladder model. Patients need to comprehend why nonopioids need to come first before adding opioids or adjuvants into the regimen. Acute surgical pain patients, in particular, must know that although opioids might initially provide relief, their ultimate aim should be reducing dependency through intravenous, oral, and then nonopioids prescription. 

Patients must also be educated on the need to use only as much pain relief medication as necessary to reach the intended pain goal. If their provider prescribes two tablets every four to six hours, for instance, it's wiser for them to start with just one and gradually add on additional pain relievers as required. They should be advised against exceeding prescribed amounts as soon as they start feeling any relief. Before initiating any medication treatment plan, patients must receive proper instruction about its name, dose, route, and frequency of administration.  

It's also essential that any special instructions regarding when it should be taken such as with or without food, be written for the patient as well as storage tips to protect medications safely away from children by either keeping out of reach or locking up safely. 

Every time they receive medication, patients should be educated on its potential adverse side effects as well as when to report them. When opioids are prescribed, patients should understand the potential risk for constipation, respiratory depression and addiction and also be advised that taking opioid medication could make them feel sleepy. Additionally, they must not consume alcohol, drive heavy machinery, take any unapproved drugs while on such medicines or take other drugs not approved by their prescriber at that time. 

Patients often hold incorrect assumptions about pain management that require being addressed. Therefore, it's crucial that an assessment be completed of each individual and any misconceptions discovered. For instance, they might fear taking opioids due to concerns they will become dependent. Although long-term opioid usage could potentially lead to dependence issues, short-term use should still be weighed against its benefits regarding being tapered as quickly as possible.

Non-Pharmacological Pain Alternatives 

Nonpharmacological interventions may be combined with or without pharmaceutical medicines as they often provide tremendous benefits. As with all treatments, nonpharmacological interventions must be documented within a plan of care to determine their ability to fulfill pain relief goals effectively. Non-pharmacological pain management techniques may fall under either complementary or alternative medicine categories. Though sometimes interchanged, there is a distinct distinction: complementary therapies work alongside pharmaceutical pain treatments while alternative therapies are practiced as an alternative from standard pharmaceuticals. 

Substance Use Disorder 

According to the Centers for Disease Control and Prevention (CDC), one out of every seven Americans reports having experienced some form of substance use disorder in the last month (25).  

Defining Substance Use Disorder (SUD) 

Substance Use Disorder, according to the Centers for Disease Control (CDC), is defined as any pattern of substance abuse which leads to clinically significant impairment or distress, from substances including alcohol, cannabis, hallucinogens, inhalants, opioids, sedatives, hypnotics, anxiolytics, stimulants, and tobacco (25). A substance use disorder (SUD) may range in severity between mild, moderate, or severe cases. 

Addiction, which is one of the more serious forms of substance use disorder (SUD), refers to continued drug consumption despite negative consequences, and should be seen as a medical disease rather than character description. Therefore, people living with SUDs should not be labeled abusers, addicts, alcoholics, or "medication seekers," since such language can be stigmatizing and isolating.  To reduce the stigma surrounding substance use disorders we focus instead on medical diagnoses of each specific case and offer effective solutions. 

Though Substance Use Disorder (SUD) is considered treatable, recovering can still be challenging for many. Individuals suffering from an SUD often cannot stop taking the substance in question without experiencing excruciating withdrawal symptoms. Sometimes another drug may help wean patients off problematic opioids, such as methadone, buprenorphine or naltrexone which are all widely prescribed to treat opioid addictions. Patients may benefit from participating in programs like 12-Step Facilitation Therapy, outpatient counseling to better understand addiction and triggers, or inpatient rehabilitation at full-time facilities that offer supportive environments without distractions or temptations for recovery.  

 

Definitions of Use and Abuse 

Understanding the differences between dependence and addiction is paramount for understanding opioid misuse and abuse. Dependence refers to physical tolerance that requires increased doses to produce desired responses. Addiction occurs when that threshold has been passed and greater amounts must be administered for desired responses to be realized. Withdrawal from drugs will often bring on physical symptoms like shaking, tremors, nausea, and vomiting.  

Addiction refers to an emotional need for drugs with desirable effects that leads to strong drug seeking behavior. Opioid dependent individuals will tend to oscillate between feeling sick without taking their prescribed dose and experiencing the desired high after taking it. Being addicted is the driving force for individuals trying to obtain and take more opioids in order to avoid withdrawal symptoms. 

Withdrawal symptoms include the following (16):  

  • Intense drug cravings 
  • Depression, withdrawal fears, anxiety 
  • Sweating, watery eyes, runny nose 
  • Restlessness, yawning 
  • Diarrhea 
  • Fever and chills 
  • Muscle spasms 
  • Tremors and joint pain 
  • Stomach cramps 
  • Nausea and vomiting 
  • Elevated heart rate and blood pressure  

 

Populations at Risk 

People at risk for opioid dependence and addiction are seen in every age, gender, ethnicity, and culture. Physical dependence varies as a genetic component has been identified, which influences how quickly a person may slide from occasional use to physical need and addiction to the drug (26). Susceptible populations have typically included the homeless, alcoholics and those with personality or mental health disorders who look for opiates to block the emotional pain of life stressors.  

Healthcare professionals who also experience great work stress have a higher risk of becoming dependent or addicted to opiates due to back injuries and easier access to narcotics in their work setting (26).  

 

How Pain Control Becomes SUD 

Scheduled drugs such as narcotics, and even alcohol have the potential to become an addictive substance. Opioid abuse may lead to opioid Use Disorder, or OUD for short. OUD occurs due to problematic patterns of opioid usage. Opioids work by stimulating endorphin release in the brain, producing feelings of pleasure that make them highly addictive. Opioid use disorder (OUD), however, often leads to physical dependence, which is when someone believes they cannot function without using certain substance(s).  

Dependence should not be mistaken for tolerance, which occurs when your body requires increasing quantities of the drug to achieve similar pain relief over time. When someone who is dependent on drugs reduces or ceases taking it altogether, withdrawal symptoms could ensue. SUDs have become a serious public health risk in the U.S.

Prevention Strategies 

The best treatment for any drug overdose is prevention. Because of the national attention to the opioid epidemic and harsh statistics of deaths caused by fentanyl overdose, political, federal, state and even pharmaceutical companies have made efforts to address the problem. One strategy is to decrease the availability of prescriptions for opioids and fentanyl, however that makes it difficult for those with real pain to receive the medication.  

Monitoring drug prescription use, and public education are additional strategies. The Food and Drug administration has produced guidelines for effective pharmacological use of opiates, which includes the identification of persons at risk, assessing a patient’s benefit vs. risk, developing, and using tools to decrease risks of opiate prescription use such as contracts for pain management and standards of required 30-day physician visits before new prescriptions can be refilled.  

The CDC Clinical Practice Guidelines for Prescribing Opioids for Pain advises healthcare providers to review a patient's history with controlled substance prescriptions prior to prescribing opioids (28).  

Providers can gain insight into a patient’s history of opioid prescribing via an electronic database tracking-controlled substance prescriptions known as Prescription Drug Monitoring Program (PDMP). PDMPs also alert healthcare providers of other medications a patient is taking that might increase his/her risk for opioid overdose, making PDMPs particularly helpful when transitioning between providers or when medication histories cannot be provided by patient themselves. Prior to prescribing opioids and at least once every three months when continuing therapy, the database should be reviewed.  

CDC Public Health Law Program: provides resources regarding state laws on prescription drug misuse and abuse.  

 

Prevention strategies include:  
  • Patient education regarding use of opiates 
  • Pain contract signed by patient to agree to terms of drug use 
  • Prescription monitoring programs to detect multiple use of pharmacies and physicians for opiates. 
  • Detection of inappropriate prescribing of opioids 
  • Photo identification to pick up opioid prescriptions 
  • Urine toxicology screening for employees 
  • Safe disposal of unused opioids 
  • Referrals to pain and addiction specialists 
  • Use of semi-synthetic opioid alternatives 

  

Patient education regarding the use of opiates, and truly all prescription medications, is essential to understand the need for the drug, its side effects, and adverse effects. An additional pain contract should be included with the patient education, which outlines the parameters for the use of the drug. Especially when used for chronic pain management, patients should be partners with the prescriber to outline when the drug will be used and for how long.  

Prescription monitoring programs include detection systems in pharmacies and the local district that identify patients who have filled a narcotic prescription. In many states, photo ID is already required for the purchase of cigarettes or alcohol and could become a beginning point to dissuade unauthorized and high frequency prescription use.  

According to the National Alliance for Model State Drug Laws, currently 85% of states require ID for narcotic prescription use (27). Some drug stores even run the name of a client picking up a narcotic prescription through a drug monitoring data system for alerts. The challenge is for busy pharmacists to take the time to use the monitoring system and for patients to be patient as the process is completed.  

 

Possible “red flags” that could lead to prescription denial:  

  • A pain medication not previously filled the pharmacy. 
  • A new doctor is writing a prescription for the same pain medication. 
  • A doctor writing a prescription who is not in a “reasonable geographic location” near the pharmacy. 
  • A patient paying for a prescription in cash. 
  • A patient seeking an early refill of a prescription. 
  • A patient seeking an “excessive” number of pills. 
  • A patient taking the same pain medication for more than 6 months. 

 

Another strategy includes receiving prior authorization before opiates can be filled. In 2007 the FDA passed an amendment to create a patient registry for opioids. In 2012, Blue Cross Blue Shield began to require prior authorization for more than a one-month supply of opioids in a two-month period. By this simple process alone in the state of Massachusetts, the number of opioid prescriptions decreased by more than 6,500,000 pills in one year (29,31). 

Safe disposal of opioids is a challenging issue as many people believe that flushing them down the toilet is appropriate, which it is not. Public education and awareness programs should also include safe medication disposal such as mixing with used coffee grounds, dirt or kitty litter and placing in a sealed container to then dispose of in the garbage. Used opioid patches should be folded in half on the sticky sides and disposed of in a sealed container in the garbage.  

 

Patient Screening Tools 

Several screening tools are available to help clinicians identify when a patient taking opioids may be experiencing dependence or addiction.  

Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidence-based practice used to identify, reduce, and prevent problematic use, abuse, and dependence on alcohol and illicit drugs” (30). The SBIRT model was inspired by a recommendation from the Institute of Medicine to increase community-based screening for health risk behaviors, including substance use. SBIRT is an early and brief intervention of 15-30 minutes and billable to Medicare/Medicaid. The screening and referral to treatment includes a patient encounter, history, physical exam, clinical diagnosis, and plan for care specific to the concern of substance abuse other than for those patients already identified with severe substance abuse. The SBIRT screening tool can be as simple as asking several key questions of patients receiving narcotics and opioids at every doctor’s office visit.  

The Opioid Risk tool is another brief screening tool of questions to help identify a patient at increased risk for dependence and abuse. Currently no one tool has been identified to be better than any others, nor is any one tool sufficient to identify drug behaviors of chronic pain patients using opioids (31, 32).  

Here is an example of an opioid screening tool:

  4. What nonpharmacological approaches to both acute and chronic pain can you confidently prescribe? 

Treatment for SUD 

Managing pain for those living with substance use disorder can be challenging. Everyone deserves respect and to have their pain appropriately managed, which requires taking an integrated, patient-centric approach to include both pharmaceutical and nonpharmaceutical interventions. Before medicating with opioids for pain management in those suffering from OUDs, nonpharmacological therapies and nonopioid medications must first be explored as effective options. Such nonpharmacological approaches might include therapeutic exercise, physical therapy, cognitive-behavioral therapy (CBT), complementary and alternative medicines as well as complementary and alternative remedies (CAMs).  

Nonopioid medications that could be useful include nonsteroidal anti-inflammatory drugs (NSAIDs), topical analgesics and adjuvant medicines like serotonin-norepinephrine reuptake inhibitors, CBT, and combination SSRI/SSNI or tricyclic antidepressants.  

If pain levels necessitate opioid use, opioids should not be withheld from patients with OUDs. As with any patient, it's essential that shared goals and risks are established along with an agreed upon treatment agreement and close monitoring via scheduled follow-up visits in order to reassess pain levels regularly. In general, starting off with a low dose and gradually increasing as needed is the standard. Creating a pain agreement with the patient is required.  

 

Reducing Stigma Against SUD 

In addition, working to decrease the stigma of SUD can be helpful for those seeking medical assistance (33). Pain clinics are a newly developed specialty, which allow patients suffering from chronic pain to work with a pain specialist for more effective management using a variety of modalities. It is estimated that at least 100 million Americans live with chronic pain. Pain clinics can offer help focusing on procedures that deal with specific pain such as neck and lower back pain.  

They can also approach pain through an interdisciplinary approach involving psychologists, physical therapists, nutritionists, occupational and vocational therapists in addition to physicians and nurses. Other modalities such as acupuncture, biofeedback, cognitive behavioral therapy, water therapy, massage and meditation can be options for chronic pain in lieu of just relying on opioids. Patient education as well as for the prescriber needs to include these alternative treatment strategies.  

Recognition of opioid use within healthcare professionals has been addressed by the National Council of State Boards of Nursing. A free educational webinar for understanding substance use disorder in nursing is available to nurses and managers to help identify signs of opioid use and abuse. It also outlines the system of helping professionals with therapy and recovery. It can be accessed at https://www.ncsbn.org/5127.htm

  3. What policies and regulations are in place to promote safe and responsible prescribing practices for narcotics for pain management? 

Acute Treatment for Overdose 

Treatment for opioid abuse generally starts with treatment of withdrawal in the acute phase. Managing symptoms of overdose and preventing death are the first objective. Securing an airway and supporting the patient during the tremors, seizures, hypertension, nausea, vomiting, and pain are often handled in an ER and medical/surgical setting.  

Naloxone (Narcan) can be used for reversal of opioid overdose and is available in IV, SQ, IM and nasal routes. If a patient is unconscious, follow the ABCs of emergency response such as calling 9-1-1, checking for a pulse, securing an open airway, and providing rescue breaths. Give the first full dose of naloxone and continue rescue breaths. If the patient doesn’t respond give the second full dose of naloxone.  

Patients will often respond quickly and be confused and possibly combative. Monitor the patient after recovery with naloxone to prevent another dose of an opioid and follow up medical attention.  

Using pharmacological blocking agents is helpful in stopping opioid overdose. Antagonist medications block opioid receptors so that the desired effect is no longer active. Two opiate substitution medications are currently available in the United States and include methadone and levomethadyl acetate but are only available in strictly regulated environments where medication is received under clinical observation and limited out-patient use.  

Methadone and buprenorphine are synthetic opioid agonists and act on the same mu receptors that opioids activate and therefore has been a popular treatment for addiction, known as Opioid Substitution Therapy (OST). Methadone has a slow onset of action and long elimination half-life of about 24 hours. A longer acting opioid receptor agonist is Buprenorphine, a partial opioid agonist and can reduce cravings and symptoms of withdrawals. These drugs can be taken less frequently and can help wean a patient from the more fatal opioids. Control trials show that it is more effective than a placebo and can help decrease fatalities from opioids. Access to these drugs is still dependent upon physician-controlled prescribing or treatment programs.  

Getting into approved treatment programs where these drugs can be given and monitored closely, in combination with behavioral therapy is often difficult, expensive, and not approved by insurance companies. The strict control of these opiate-substitution drugs is necessary because they do produce a euphoric sensation like the opiates and the tight regulation is due to the fear of creating a new market of illicit use for these. These medications can be given in sublingual, oral and even intranasal forms. By giving these opioid antagonist drugs, they act as competition for the mu receptors and ideally block the effectiveness of other opiates.  

Future of SUD Efforts 

Our nation’s opioid epidemic and increase in SUD prevalence is complicated and concerning. Thousands of lives are lost needlessly due to SUD addiction and overdose. Education of prescribers and patients is needed. Legislation is needed and debated for opioids available on the market and how to regulate their use.  

States must decide on the training and availability for the use of naloxone and opioid agonists for overdose and weaning. Healthcare professionals must learn to collaborate with pharmacists, nutritionists and behaviorists who work with those with chronic pain to offer more options for pain management. Schools and public officials such as police workers must be able to improve security to dissuade drug sales.  

Each of the proposed strategies to fight our national war on drugs is at various stages of development and implementation and take time. The cost to implement programs, educate stakeholders and evaluate any negative consequences to appropriate treatment plans for pain needs patience. In the meantime, small efforts can save lives. Your efforts to learn more about the substance use disorder and the opioid epidemic are a notable step for improvement.

Introduction   

Pain is complex and subjective. The experience of pain can significantly impact an individual’s quality of life. According to the National Institute of Health (NIH) (40), pain is the most common complaint in a primary care office, with 20% of all patients reporting pain. Chronic pain is the leading cause of disability, and effective pain management is crucial to health and well-being, particularly when it improves functional ability. Effective pain treatment starts with a comprehensive, empathic assessment and a desire to listen and understand. Nurse Practitioners are well-positioned to fill a vital role in providing comprehensive and empathic patient care, including pain management (23).

While the incidence of chronic pain has remained a significant problem, how clinicians manage pain has significantly changed in the last decade, primarily due to the opioid epidemic. This education aims to discuss pain and the assessment of pain, federal guidelines for prescribing, the opioid epidemic, addiction and diversion, and recommendations for managing pain.

Definition of Pain

Understanding the definition of pain, differentiating between various types of pain, and recognizing the descriptors patients use to communicate their pain experiences are essential for Nurse practitioners involved in pain management. By understanding the medical definition of pain and how individuals may communicate it, nurse practitioners can differentiate varying types of pain to target assessment.

According to the International Association for the Study of Pain (27), pain is “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or terms of described such in damage.” The IASP, in July 2020, expanded its definition of pain to include context further.

Their expansion is summarized below:

  • Pain is a personal experience influenced by biological, psychological, and social factors.
  • Pain cannot be inferred solely from activity in sensory neurons.
  • Individuals learn the concept of pain through their life experiences.
  • A person’s report of an experience in pain should be respected.
  • Pain usually serves an adaptive role but may adversely affect function and social and psychological well-being.
  • The inability to communicate does not negate the possibility of the experience of pain.

Types of Pain

Pain originates from different mechanisms, causes, and areas of the body. As a nurse practitioner, understanding the type of pain a patient is experiencing is essential for several reasons (23).

  • Determining an accurate diagnosis. This kind of pain can provide valuable clues to the underlying cause or condition.
  • Creating a treatment plan. Different types of pain respond better to specific treatments or interventions.
  • Developing patient education. A nurse practitioner can provide targeted education to patients about their condition, why they may experience the pain as they do, its causes, and treatment options. Improving the patient's knowledge and control over their condition improves outcomes.

 

Acute Pain

Acute pain is typically short-lived and is a protective response to an injury or illness. Patients are usually able to identify the cause. This type of pain resolves as the underlying condition improves or heals (12).

 

Chronic Pain

Chronic pain is diagnosed when it continues beyond the expected healing time. Pain is defined as chronic when it persists for longer than three months. It may result from an underlying disease or injury or develop without a clear cause. Chronic pain often significantly impacts a person's physical and emotional well-being, requiring long-term management strategies. The prolonged experience of chronic pain usually indicates a central nervous system component of pain that may require additional treatment. Patients with centralized pain often experience allodynia or hyperalgesia (12).

Allodynia is pain evoked by a stimulus that usually does not cause pain, such as a light touch. Hyperalgesia is the effect of a heightened pain response to a stimulus that usually evokes pain (12).

 

Nociceptive Pain

Nociceptive pain arises from activating peripheral nociceptors, specialized nerve endings that respond to noxious stimuli. This type of pain is typically associated with tissue damage or inflammation and is further classified into somatic and visceral pain subtypes.

Somatic pain is most common and occurs in muscles, skin, or bones; patients may describe it as sharp, aching, stiffness, or throbbing.

Visceral pain occurs in the internal organs, such as indigestion or bowel spasms. It is more vague than somatic pain; patients may describe it as deep, gnawing, twisting, or dull (12).

 

Neuropathic pain

Neuropathic pain is a lesion or disease of the somatosensory nervous system. Examples include trigeminal neuralgia, painful polyneuropathy, postherpetic neuralgia, and central poststroke pain (10).

Neuropathic pain may be ongoing, intermittent, or spontaneous pain. Patients often describe neuropathic pain as burning, prickling, or squeezing quality. Neuropathic pain is a common chronic pain. Patients commonly describe allodynia and hyperalgesia as part of their chronic pain experience (10).

 

Affective pain

Affective descriptors reflect the emotional aspects of pain and include terms like distressing, unbearable, depressing, or frightening. These descriptors provide insights into the emotional impact of pain on an individual's well-being (12).

Case Study

Mary Adams is a licensed practical nurse who has just relocated to town. Mary will be the utilization review nurse at a local long-term care facility. Mary was diagnosed with Postherpetic Neuralgia last year, and she is happy that her new job will have her mostly doing desk work and not providing direct patient care as she had been before the relocation. Mary was having difficulty at work at her previous employer due to pain. She called into work several times, and before leaving, Mary's supervisor had counseled her because of her absences.

Mary wants to establish primary care immediately because she needs ongoing pain treatment. She is hopeful that, with her new job and pain under control, she will be able to continue a successful career in nursing. When Mary called the primary care office, she specifically requested a nurse practitioner as her primary care provider because she believes that nurse practitioners tend to spend more time with their patients.

Assessment

The assessment effectively determines the type of treatment needed, the options for treatment, and whether the patient may be at risk for opioid dependence. Since we know that chronic pain can lead to disability and pain has a high potential to negatively affect the patient's ability to work or otherwise, be productive, perform self-care, and potentially impact family or caregivers, it is imperative to approach the assessment with curiosity and empathy. This approach will ensure a thorough review of pain and research on pain management options. Compassion and support alone can improve patient outcomes related to pain management (23).

 

Record Review

Regardless of familiarity with the patient, reviewing the patient's treatment records is essential, as the ability to recall details is unreliable. Reviewing the records can help identify subtle changes in pain description and site, the patient's story around pain, failed modalities, side effects, and the need for education, all impacting further treatment (23).

Research beforehand the patient's current prescription and whether or not the patient has achieved the maximum dosage of the medication. Analysis of the patient's past prescription could reveal a documented failed therapy even though the patient did not receive the maximum dose (23).

A review of documented allergens may indicate an allergy to pain medication. Discuss with the patient the specific response to the drug to determine if it is a true allergy, such as hives or anaphylaxis, or if the response may have been a side effect, such as nausea and vomiting.

Research whether the patient tried any non-medication modalities for pain, such as physical therapy (PT), occupational therapy (OT), or Cognitive Behavioral Therapy (CBT). Note any non-medication modalities documented as failed therapies. The presence of any failed therapies should prompt further discussion with the patient, family, or caregiver about the experience. The incompletion of therapy should not be considered failed therapy. Explore further if the patient abandoned appointments.

 

Case Study

You review the schedule for the week, and there are three new patient appointments. One is Mary Adams. The interdisciplinary team requested and received Mary's treatment records from her previous primary care provider. You make 15 minutes available to review Mary's records and the questionnaire Mary filled out for her upcoming appointment. You see that Mary has been diagnosed with Postherpetic Neuralgia and note her current treatment regimen, which she stated was ineffective. You write down questions you will want to ask Mary. You do not see evidence of non-medication modalities or allergies to pain medication.

Pain Assessment

To physically assess pain, several acronyms help explore all the aspects of the patient's experience. Acronyms commonly used to assess pain are SOCRATES, OLDCARTS, and COLDERAS. These pain assessment acronyms are also helpful in determining treatment since they include a character and duration of pain assessment (23).

 

O-Onset S-Site C-Character
L-Location O-Onset O-Onset
D-Duration C-Character L-Location
C-Character R-Radiate D-Duration
A-Alleviating A-Associated symptoms E-Exacerbating symptoms
R-Radiating, relieving T-Time/Duration R-Relieving, radiating
T-Temporal patterns (frequency) E-Exacerbating A-Associated symptoms
S-Symptoms S-Severity S-Severity of illness

 

Inquire where the patient is feeling pain. The patient may have multiple areas and types of pain. Each type and location must be explored and assessed. Unless the pain is from a localized injury, a body diagram map, as seen below, is helpful to document, inform, and communicate locations and types of pain. In cases of Fibromyalgia, rheumatoid arthritis, or other centralized or widespread pain, it is vital to inquire about radiating pain. The patient with chronic pain could be experiencing acute pain or a new pain site, such as osteoarthritis, that may need further evaluation and treatment (23).

Inquire with the patient how long their pain has been present and any associated or known causative factors. Pain experienced longer than three months defines chronic versus acute pain. Chronic pain means that the pain is centralized or a function of the Central Nervous system, which should guide treatment decisions.

To help guide treatment, ask the patient to describe their pain. The description helps identify what type of pain the patient is experiencing: Allodynia and hyperalgesia indicate centralized pain; sharp, shooting pain could indicate neuropathic pain. Have the patient rate their pain. There are various tools, as shown below, for pain rating depending on the patient's ability to communicate. Not using the pain rating number alone is imperative. Ask the patient to compare the severity of pain to a previous experience. For example, a 1/10 may be experienced as a bumped knee or bruise, whereas a 10/10 is experienced on the level of a kidney stone or childbirth (23).

Besides the 0-10 rating scale and depending on the patient's needs, several pain rating scales are appropriate. They are listed below.

The 0-5 and Faces scales may be used for all adult patients and are especially effective for patients experiencing confusion.

The Defense and Veterans Pain Rating Scale (DVPRS) is a five-item tool that assesses the impact of pain on sleep, mood, stress, and activity levels (20).

For patients unable to self-report pain, such as those intubated in the ICU or late-stage neurological diseases, the FLACC scale is practical. The FLACC scale was initially created to assess pain in infants. Note: The patient need not cry to be rated 10/10.

 

Behavior 0 1 2
Face No particular expression or smile Occasional grimace or frown, withdrawn, disinterested Frequent or constant quivering chin, clenched jaw
Legs Normal position or relaxed Uneasy, restless, tense Kicking or legs drawn
Activity Lying quietly, in a normal position, or relaxed Squirming, shifting back and forth, tense Arched, rigid, or jerking
Cry No cry wake or asleep Moans or whimpers: occasional complaints Crying steadily, screams, sobs, frequent complaints
Consolability Content, relaxed Distractable, reassured by touching, hugging, or being talked to Difficult to console or comfort

(21).

 

Assess contributors to pain such as insomnia, stress, exercise, diet, and any comorbid conditions. Limited access to care, socioeconomic status, and local culture also contribute to the patient's experience of pain (23). Most patients have limited opportunity to discuss these issues, and though challenging to bring up, it is compassionate and supportive care. A referral to social work or another agency may be helpful if you cannot explore it fully.

Assess for substance abuse disorders, especially among male, younger, less educated, or unemployed adults. Substance abuse disorders increase the likelihood of misuse disorder and include alcohol, tobacco, cannabis, cocaine, and heroin (29).

Inquire as to what changes in function the pain has caused. One question to ask is, "Were it not for pain, what would you be doing?" As seen below, a Pain, Enjoyment, and General Activity (PEG) three-question scale, which focuses on function and quality of life, may help determine the severity of pain and the effect of treatment over time.

 

What number best describes your pain on average in the past week? 0-10
What number best describes how, in the past week, pain has interfered with your enjoyment of life? 0-10
What number determines how, in the past week, pain has interfered with your general activity? 0-10

(21).

 

Assess family history, mental health disorders, chronic pain, or substance abuse disorders. Each familial aspect puts patients at higher risk for developing chronic pain (23).

Evaluate for mental health disorders the patient may be experiencing, particularly anxiety and depression. The Patient Health Questionnaire (PHQ4) is a four-question tool for assessing depression and anxiety.

In some cases, functional MRI or imaging studies effectively determine the cause of pain and the treatment. If further assessment is needed to diagnose and treat pain, consult Neurology, Orthopedics, Palliative care, and pain specialists (23).

 

Case Study

You used OLDCARTS to evaluate Mary's pain and completed a body diagram. Mary is experiencing allodynia in her back and shoulders, described as burning and tingling. It is exacerbated when she lifts, such as moving patients at the long-term care facility and, more recently, boxes from her move to the new house. Mary has also been experiencing anxiety due to fear of losing her job, the move, and her new role. She has moved closer to her family to help care for her children since she often experiences fatigue. Mary has experienced a tumultuous divorce in the last five years and feels she is still undergoing some trauma.

You saw in the chart that Mary had tried Gabapentin 300 mg BID for her pain and inquired what happened. Mary explained that her pain improved from 8/10 to 7/10 and had no side effects. Her previous care provider discontinued the medication and documented it as a failed therapy. You reviewed the minimum and maximum dosages of Gabapentin and know Mary can take up to 1800mg/day.

During the assessment, Mary also described stiffness and aching in her left knee. She gets a sharp pain when she walks more than 500 steps, and her knee is throbbing by the end of the day. Mary rated the pain a 10/10, but when she compared 10/10 to childbirth, Mary said her pain was closer to 6/10. Her moderate knee pain has reduced Mary's ability to exercise. She used to like to take walks. Mary stated she has had knee pain for six months and has been taking Ibuprofen 3 – 4 times daily.

Since Mary's pain is moderate, you evaluate your options of drugs for moderate to severe pain.

Opioid Classifications and Drug Schedules

A comprehensive understanding of drug schedules and opioid classifications is essential for nurse practitioners to ensure patient safety, prevent drug misuse, and adhere to legal and regulatory requirements. Nurse practitioners with a comprehensive understanding of drug schedules and opioid classifications can effectively communicate with colleagues, ensuring accurate medication reconciliation and facilitating interdisciplinary care. Nurse practitioners’ knowledge in facilitating discussions with pharmacists regarding opioid dosing, potential interactions, and patient education is essential (49).

Drug scheduling became mandated under the Controlled Substance Act. The Drug Enforcement Agency (DEA) Schedule of Controlled Drugs and the criteria and common drugs are listed below.

Commonly Prescribed Opioids, Indications for Use, and Typical Side Effects

Opioid medications are widely used for managing moderate to severe pain. Referencing NIDA (2023), this section aims to give healthcare professionals an overview of the indications and typical side effects of commonly prescribed Schedule II opioid medications, including hydrocodone, oxycodone, morphine, Fentanyl, and hydromorphone.

Opioids are derived and manufactured in several ways. Naturally occurring opioids come directly from the opium poppy plant. Synthetic opioids are manufactured by chemically synthesizing compounds that mimic the effects of a natural opioid. Semi-synthetic is a mix of naturally occurring and man-made (35).

Understanding the variations in how an opioid is derived and manufactured is crucial in deciding the type of opioid prescribed, as potency and analgesic effects differ. Synthetic opioids are often more potent than naturally occurring opioids. Synthetic opioids have a longer half-life and slower elimination, affecting the duration of action and timing for dose adjustments. They are also associated with a higher risk of abuse and addiction (38).

 

Hydrocodone
Mechanism of Action and Metabolism

Hydrocodone is a Schedule II medication. It is an opioid agonist and works as an analgesic by activating mu and kappa opioid receptors located in the central nervous system and the enteric plexus of the bowel. Agonist stimulation of the opioid receptors inhibits nociceptive neurotransmitters' release and reduces neuronal excitability (17).

  • Produces analgesia.
  • Suppresses the cough reflex at the medulla.
  • Causes respiratory depression at higher doses.

Hydrocodone is indicated for treating severe pain after nonopioid therapy has failed. It is also indicated as an antitussive for nonproductive cough in adults over 18.

 

Available Forms

Hydrocodone immediate release (IR) reaches maximum serum concentrations in one hour with a half-life of 4 hours.  Extended-release (ER) Hydrocodone reaches peak concentration at 14-16 hours and a half-life of 7 to 9 hours. Hydrocodone is metabolized to an inactive metabolite in the liver by cytochrome P450 enzymes CYP2D6 and CYP3A4. Hydrocodone is converted to hydromorphone and is excreted renally. Plasma concentrations of hydromorphone are correlated with analgesic effects rather than hydrocodone.

Hydrocodone is formulated for oral administration into tablets, capsules, and oral solutions. Capsules and tablets should never be crushed, chewed, or dissolved. These actions convert the extended-release dose into immediate release, resulting in uncontrolled and rapid release of opioids and possible overdose.

 

Dosing and Monitoring

Hydrocodone IR is combined with acetaminophen or ibuprofen. The dosage range is 2.5mg to 10mg every 4 to 6 hours. If formulated with acetaminophen, the dosage is limited to 4gm/day.

Hydrocodone ER is available as tablets and capsules. Depending on the product, the dose of hydrocodone ER formulations in opioid-naïve patients is 10 to 20 mg every 12 to 24 hours.

Nurse practitioners should ensure patients discontinue all other opioids when starting the extended-release formula.

 

Side Effects and Contraindications

Because mu and kappa opioid receptors are in the central nervous system and enteric plexus of the bowel, the most common side effects of hydrocodone are constipation and nausea (>10%).

Other adverse effects of hydrocodone include:

  • Respiratory: severe respiratory depression, shortness of breath
  • Cardiovascular: hypotension, bradycardia, peripheral edema
  • Neurologic: Headache, chills, anxiety, sedation, insomnia, dizziness, drowsiness, fatigue
  • Dermatologic: Pruritus, diaphoresis, rash
  • Gastrointestinal: Vomiting, dyspepsia, gastroenteritis, abdominal pain
  • Genitourinary: Urinary tract infection, urinary retention
  • Otic: Tinnitus, sensorineural hearing loss
  • Endocrine: Secondary adrenal insufficiency (17)

Hydrocodone, being an agonist, must not be taken with other central nervous system depressants as sedation and respiratory depression can result. In formulations combined with acetaminophen, hydrocodone can increase the international normalized ratio (INR) and cause bleeding.  Medications that induce or inhibit cytochrome enzymes can lead to wide variations in absorption.

 

The most common drug interactions are listed below:

  • Alcohol
  • Benzodiazepines
  • Barbiturates
  • other opioids
  • rifampin
  • phenytoin
  • carbamazepine
  • cimetidine,
  • fluoxetine
  • ritonavir
  • erythromycin
  • diltiazem
  • ketoconazole
  • verapamil
  • Phenytoin
  • John’s Wort
  • Glucocorticoids

 

Considerations

Use with caution in the following:

  • Patients with Hepatic Impairment: Initiate 50% of the usual dose
  • Patients with Renal Impairment: Initiate 50% of the usual dose
  • Pregnancy: While not contraindicated, the FDA issued a black-boxed warning since opioids cross the placenta, and prolonged use during pregnancy may cause neonatal opioid withdrawal syndrome (NOWS).
  • Breastfeeding: Infants are susceptible to low dosages of opioids. Non-opioid analgesics are preferred.

Pharmacogenomic: Genetic variants in hydrocodone metabolism include ultra-rapid, extensive, and poor metabolizer phenotypes. After administration of hydrocodone, hydromorphone levels in rapid metabolizers are significantly higher than in poor metabolizers.

 

Oxycodone
Mechanism of Action and Metabolism

Oxycodone has been in use since 1917 and is derived from Thebaine. It is a semi-synthetic opioid analgesic that works by binding to mu-opioid receptors in the central nervous system. It primarily acts as an agonist, producing analgesic effects by inhibiting the transmission of pain signals (Altman, Clark, Huddart, & Klein, 2018).

Oxycodone is primarily metabolized in the liver by CYP3A4/5. It is metabolized in the liver to noroxycodone and oxymorphone.  The metabolite oxymorphone also has an analgesic effect and does not inhibit CYP3A4/5. Because of this metabolite, oxycodone is more potent than morphine, with fewer side effects and less drug interactions. Approximately 72% of oxycodone is excreted in urine (Altman, Clark, Huddart, & Klein, 2018).

 

Available Forms

Oxycodone can be administered orally, rectally, intravenously, and as an epidural. For this sake, we will focus on immediate-release and extended-release oral formulations.

  • Immediate-release (IR) tablets
  • IR capsules
  • IR oral solutions
  • Extended-release (ER) tablets

 

Dosing and Monitoring

The dosing of oxycodone should be individualized based on the patient's pain severity, previous opioid exposure, and response. Initial dosages for opioid naïve patients range from 5-15 mg for immediate-release formulations, while extended-release formulations are usually initiated at 10-20 mg. Dosage adjustments may be necessary based on the patient's response, but caution should be exercised. IR and ER formulations reach a steady state at 24 hours and titrating before 24 hours may lead to overdose.

Regular monitoring is essential to assess the patient's response to treatment, including pain relief, side effects, and signs of opioid misuse or addiction. Monitoring should include periodic reassessment of pain intensity, functional status, and adverse effects (Altman, Clark, Huddart, & Klein, 2018).

 

Side Effects and Contraindications

Common side effects of oxycodone include:

  • constipation
  • nausea
  • sedation
  • dizziness
  • respiratory depression
  • respiratory arrest
  • hypotension
  • fatal overdose

Oxycodone is contraindicated in patients with known hypersensitivity to opioids, severe respiratory depression, paralytic ileus, or acute or severe bronchial asthma. It should be used cautiously in patients with a history of substance abuse, respiratory conditions, liver or kidney impairment, and those taking other medications that may interact with opioids, such as alcohol (4).

 

It is also contraindicated with the following medications and classes:

  • Antifungal agents
  • Antibiotics
  • Rifampin
  • Carbamazepine
  • Fluoxetine
  • Paroxetine

 

Considerations
  • Nurse practitioners should consider the variations in the mechanism of action for the following:
  • Metabolism differs between males and females: females have been shown to have less concentration of oxymorphone and more CYP3A4/5 metabolites.
  • Infants have reduced clearance of oxycodone, increasing side effects.
  • Pediatrics have 20-40% increased clearance over adults.
  • Reduced clearance with age increases the half-life of oxycodone.
  • Pregnant women have a greater clearance and reduced half-life.
  • Impairment of the liver reduces clearance.
  • Cancer patients with cachexia have increased exposure to oxycodone and its metabolite.
  • Maternal and neonate concentrations are similar, indicating placenta crossing (4)

 

Morphine

 

 

 

 

Mechanism of Action and Metabolism

Morphine is a naturally occurring opioid alkaloid extracted from the opium poppy. It was isolated in 1805 and is the opioid against which all others are compared. Morphine binds to mu-opioid receptors in the brain and spinal cord, inhibiting the transmission of pain signals and producing analgesia. It is a first-line choice of opioid for moderate to severe acute, postoperative, and cancer-related pain (8).

Morphine undergoes first-pass metabolism in the liver and gut. It is well absorbed and distributed throughout the body. Its main metabolites are morphine-3-glucuronide and morphine-6-glucuronide. Its mean plasma elimination half-life after intravenous administration is about 2 hours. Approximately 90% of morphine is excreted in the urine within 24 hours (8).

 

Available Forms

Morphine is available in various forms, including.

  • immediate-release tablets
  • extended release tablets
  • oral IR solutions
  • injectable solutions
  • transdermal patches

 

Dosing and Monitoring

Morphine is hydrophilic and, as such, has a slow onset time. The advantage of this is that it is unlikely to cause acute respiratory depression even when injected. However, because of the slow onset time, there is more likelihood of morphine overdose due to the ability to “stack” doses in patients experiencing severe pain (Bistas, Lopez-Ojeda, & Ramos-Matos, 2023).

The dosing of morphine depends on the patient's pain severity, previous opioid exposure, and other factors. It is usually initiated at a low dose and titrated upwards as needed. Monitoring pain relief, adverse effects, and signs of opioid toxicity is crucial. Reevaluate benefits and harms with patients within 1 to 4 weeks of starting opioid therapy or of dose escalation. General recommendations for initiating morphine (Bistas, Lopez-Ojeda, & Ramos-Matos, 2023).

Prescribe IR opioids instead of ER opioids.

Prescribe the lowest effective dosage, below 50 Morphine Milligram Equivalents (MME) /day.

 

Side Effects and Contraindications

Because morphine binds to opioid receptors in the brain and spinal cord, is metabolized in the liver and gut, and has a slow onset, the following side effects are common:

  • Constipation
  • Nausea
  • Vomiting
  • Sedation
  • Dizziness
  • Respiratory depression
  • Pruritis
  • Sweating
  • Dysphoria/Euphoria
  • Dry mouth
  • Anorexia
  • Spasms of urinary and biliary tract

 

Contraindications of morphine are:
  • Known hypersensitivity or allergy to morphine.
  • Bronchial asthma or upper airway obstruction
  • Respiratory depression in the absence of resuscitative equipment
  • Paralytic ileus
  • Risk of choking in patients with dysphagia, including infants, children, and the elderly (8)

Concurrent use with other sedating medications: Amitriptyline, diazepam, haloperidol, chlorpromazine

 

Morphine interacts with the following medications:

  • Ciprofloxacin
  • Metoclopramide
  • Ritonavir

 

Considerations for Nurse Practitioners

Assess for medical conditions that may pose serious and life-threatening risks with opioid use, such as the following:

  • Sleep-disordered breathing, such as sleep apnea.
  • Pregnancy
  • Renal or hepatic insufficiency
  • Age >= 65
  • Certain mental health conditions
  • Substance use disorder
  • Previous nonfatal overdose

 

 

Fentanyl
Mechanism of Action and Metabolism

Fentanyl is a synthetic opioid more potent than morphine and was approved in 1968. Fentanyl is an agonist that works by binding to the mu-opioid receptors in the central nervous system. This binding inhibits the transmission of pain signals, resulting in analgesia. Fentanyl is often used for severe pain management, particularly in the perioperative and palliative care settings, or for severe pain in patients with Hepatic failure (8).

It is a mu-selective opioid agonist. However, it can activate other opioid receptors in the body, such as the delta and kappa receptors, producing analgesia. It also activates the Dopamine center of the brain, stimulating relaxation and exhilaration, which is responsible for its high potential for addiction (8).

 

Indications for fentanyl are as follows:

  • Preoperative analgesia
  • Anesthesia adjunct
  • Regional anesthesia adjunct
  • General anesthesia
  • Postoperative pain control
  • Moderate to severe acute pain (off-label)

 

Available Forms
  • Fentanyl is available in various forms, including:
  • transdermal patches
  • injectable solutions
  • lozenges
  • nasal sprays
  • oral tablets (8)

 

Dosing and Monitoring

Fentanyl is metabolized via the CYP3A4 enzyme in the liver. It has a half-life of 3 to 7 hours, and 75% of Fentanyl is excreted in the urine and 9% in feces.

The dosing of fentanyl depends on the route of administration and the patient's needs. For example, transdermal patches are typically applied every 72 hours, while injectable solutions are titrated to achieve the desired analgesic effect. Monitoring should include assessing pain levels, respiratory rate, blood pressure, and sedation scores (8).

 

Fentanyl is most dosed as follows:

  • Post-operative pain control
  • 50 to 100 mcg IV/IM every 1 to 2 hours as needed; alternately 0.5 to 1.5 mcg/kg/hour IV as needed. Consider lower dosing in patients 65 and older.

PCA (patient-controlled analgesia): 10 to 20 mcg IV every 6 to 20 minutes as needed; start at the lowest effective dose for the shortest effective duration - refer to institutional protocols (8).

Moderate to severe acute pain (off-label) 1 to 2 mcg/kg/dose intranasally each hour as needed; the maximum dose is 100 mcg. Use the lowest effective dose for the shortest effective duration (8).

 

Side Effects and Contraindications

Common side effects of fentanyl include:

  • respiratory depression
  • sedation
  • constipation
  • nausea
  • vomiting
  • euphoria
  • confusion
  • respiratory depression/arrest
  • visual disturbances
  • dyskinesia
  • hallucinations
  • delirium
  • narcotic ileus
  • muscle rigidity
  • addiction
  • loss of consciousness
  • hypotension
  • coma
  • death (8).

 

The use of fentanyl is contraindicated in patients in the following situations:

  • After operative interventions in the biliary tract, these may slow hepatic elimination of the drug.
  • With respiratory depression or obstructive airway diseases (i.e., asthma, COPD, obstructive sleep apnea, obesity hyperventilation, also known as Pickwickian syndrome)
  • With liver failure
  • With known intolerance to fentanyl or other morphine-like drugs, including codeine or any components in the formulation.
  • With known hypersensitivity (i.e., anaphylaxis) or any common drug delivery excipients (i.e., sodium chloride, sodium hydroxide) (8).

Considerations for Nurse Practitioners

Nurse practitioners prescribing fentanyl should thoroughly assess the patient's pain, medical history, and potential risk factors for opioid misuse. They should also educate patients about the proper use, storage, and disposal of fentanyl. It should be used cautiously in patients with respiratory disorders, liver or kidney impairment, or a history of substance abuse. Fentanyl is contraindicated in patients with known hypersensitivity to opioids and those without exposure to opioids.

Alcohol and other drugs, legal or illegal, can exacerbate fentanyl's side effects, creating multi-layered clinical scenarios that can be complex to manage. These substances, taken together, generate undesirable conditions that complicate the patient's prognosis (8).

 

Hydromorphone
Mechanism of Action and Metabolism

Hydromorphone is a semi-synthetic opioid derived from morphine. It binds to the mu-opioid receptors in the central nervous system. It primarily exerts its analgesic effects by inhibiting the release of neurotransmitters involved in pain transmission, thereby reducing pain perception. Hydromorphone also exerts its effects centrally at the medulla level, leading to respiratory depression and cough suppression (1).

 

Hydromorphone is indicated for:

  • moderate to severe acute pain
  • severe chronic pain
  • refractory cough suppression (off-label) (1)

 

Available Forms

Hydromorphone is available in various forms, depending on the patient’s needs and severity of pain.

  • immediate-release tablet
  • extended release tablets
  • oral liquid
  • injectable solution
  • rectal suppositories

 

Dosing and Monitoring

The immediate-release oral formulations of hydromorphone have an onset of action within 15 to 30 minutes. Peak levels are typically between 30 and 60 minutes with a half-life of 2 to 3 hours. Hydromorphone is primarily excreted through the urine.

The dosing of hydromorphone should be individualized based on the patient's pain intensity, initiated at the lowest effective dose, and adjusted gradually as needed. Close monitoring of pain relief, adverse effects, and signs of opioid toxicity is essential. Patients should be assessed regularly to ensure they receive adequate pain control without experiencing excessive sedation or respiratory depression.

The following are standard dosages that should only be administered when other opioid and non-opioid options fail.

  • Immediate-release oral solutions dosage: 1 mg/1 mLoral tablets are available in 2 mg, 4 mg, and 8 mg.
  • Extended-release oral tablets are available in dosages of 8 mg, 12 mg, 16 mg, and 32 mg.
  • Injection solutions are available in concentrations of 1 mg/mL, 2 mg/mL, 4 mg/mL, and 10 mg/mL.
  • Intravenous solutions are available in strengths of 2 mg/1 mL, 2500 mg/250 mL, ten mg/1 mL, and 500 mg/50 mL.
  • Suppositories are formulated at a strength of 3 mg (1).

 

Side Effects and Contraindications

Hydromorphone has potential adverse effects on several organ systems, including the integumentary, gastrointestinal, neurologic, cardiovascular, endocrine, and respiratory.

 

Common side effects of hydromorphone include:

  • Constipation
  • Nausea
  • Vomiting
  • Dizziness
  • Sedation
  • respiratory depression
  • pruritus
  • headache
  • Somnolence
  • Severe adverse effects of hydromorphone include:
  • Hypotension
  • Syncope
  • adrenal insufficiency
  • coma
  • raised intracranial pressure.
  • seizure
  • suicidal thoughts
  • apnea
  • respiratory depression or arrest
  • drug dependence or withdrawal
  • neonatal drug withdrawal syndrome
  • Hydromorphone is contraindicated in patients with:
  • known allergies to the drug, sulfites, or other components of the formulation.
  • known hypersensitivity to opioids.
  • severe respiratory depression
  • paralytic ileus
  • acute or severe bronchial asthma (1).

 

Caution should be exercised in patients with:

  • respiratory insufficiency
  • head injuries
  • increased intracranial pressure.
  • liver or kidney impairment.

 

Considerations for Nurse Practitioners

As nurse practitioners, it is crucial to assess the patient's pain intensity and overall health status before initiating Hydromorphone. Start with the lowest effective dose and titrate carefully for optimal pain control. Regular monitoring for adverse effects, signs of opioid toxicity, and therapeutic response is essential. Educate patients about the potential side effects, proper dosing, and the importance of not exceeding prescribed doses. Additionally, nurse practitioners should be familiar with local regulations and guidelines regarding opioid prescribing and follow appropriate documentation and monitoring practices.

 

Additional Considerations

In terminal cancer patients, clinicians should not restrain opioid therapy even if signs of respiratory depression become apparent.

Hydromorphone requires careful administration in cases of concurrent psychiatric illness.

 

Specific Patient Considerations:
  • Hepatic impairment and Renal Impairment: Initiate hydromorphone treatment at one-fourth to one-half of the standard starting dosage, depending on the degree of impairment.
  • Pregnancy considerations: Hydromorphone can traverse the placental barrier and induce NOWS.
  • Breastfeeding considerations: Nonopioid analgesic agents are preferable for breastfeeding women.
  • Older patients: hydromorphone is categorized as a potentially inappropriate medication for older adults (1).

 

Tramadol

 

 

 

 

Mechanism of Action and Metabolism

Tramadol is a Schedule IV opioid medication with a higher potential for dependency and misuse than non-opioid medications. It binds to opioid receptors in the central nervous system, inhibiting the reuptake of norepinephrine and serotonin. It also has weak mu-opioid receptor agonist activity.

The liver metabolizes tramadol mediated by the cytochrome P450 pathways (particularly CYP2D6) and is mainly excreted through the kidneys.

Tramadol is used for moderate to severe pain.

 

Available Forms of Tramadol include:
  • Immediate-release-typically used for acute pain management.
  • Extended-release-used for chronic pain.

 

Dosing and Monitoring

Tramadol has an oral bioavailability of 68% after a single dose and 90–100% after multiple doses and reaches peak concentrations within 2 hours. Approximately 75% of an oral dose is absorbed, and the half-life of tramadol is 9 hours (18).

Tramadol dosing should be individualized based on the patient's pain severity and response.

The initial dose for adults is usually 50-100 mg orally every 4-6 hours for pain relief. The maximum daily dose is 400 mg for immediate-release formulations and 300 mg for extended-release formulations (18).

It is essential to monitor the patient's pain intensity, response to treatment, and any adverse effects. Regular reassessment and adjustment of the dosage may be necessary.

 

Side Effects and Contraindications

Tramadol is responsible for severe intoxications leading to consciousness disorder (30%), seizures (15%), agitation (10%), and respiratory depression (5%). The reactions to Tramadol suggest that the decision to prescribe should be carefully considered.

 

Common Side Effects of Tramadol Include:
  • Nausea
  • Vomiting
  • Dizziness
  • Constipation
  • Sedation
  • Headache
  • CNS depression
  • Seizure
  • Agitation
  • Tachycardia
  • Hypertension
  • reduced appetite
  • pruritus and rash
  • gastric irritation

 

Serious side effects include:
  • respiratory depression
  • serotonin syndrome
  • seizures

 

Contraindications

Tramadol is contraindicated in patients with:

  • history of hypersensitivity to opioids
  • acute intoxication with alcohol
  • opioids, or other psychoactive substances
  • Patients who have recently received monoamine oxidase inhibitors (MAOIs)

 

Additionally, the following can be observed in tramadol intoxication:

  • miosis
  • respiratory depression
  • decreased level of consciousness
  • hypertension
  • tremor
  • irritability
  • increased deep tendon reflexes

 

Poisoning leads to:

  • multiple organ failure
  • coma
  • cardiopulmonary arrest
  • death

 

Considerations for Nurse Practitioners

Tramadol has been increasingly misused with intentional overdoses or intoxications. Suicide attempts were the most common cause of intoxication (52–80%), followed by abuse (18–31%), and unintentional intoxication (1–11%). Chronic tramadol or opioid abuse was reported in 20% of tramadol poisoning cases. Fatal tramadol intoxications are uncommon except when ingested concurrent with depressants, most commonly benzodiazepines and alcohol (18).

 

Tramadol poisoning can affect multiple organ systems:
  • gastrointestinal
  • central nervous system: seizure, CNS depression, low-grade coma, anxiety, and over time anoxic brain damage
  • Cardiovascular system: palpitation, mild hypertension to life-threatening complications such as cardiopulmonary arrest
  • respiratory system
  • renal system: renal failure with higher doses of tramadol intoxication
  • musculoskeletal system: rhabdomyolysis
  • endocrine system: hypoglycemia, serotonin syndrome (18)

 

Cannabis
Mechanism of Action and Metabolism

Cannabis is classified as a Schedule I status. It contains various cannabinoids, with delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) being the most studied. THC primarily acts on cannabinoid receptors in the brain, producing psychoactive effects, while CBD has more diverse effects on the nervous system. These cannabinoids interact with the endocannabinoid system, modulating neurotransmitter release and influencing various physiological processes (32).

Similar to opioids, cannabinoids are synthesized and released in the body by synapses that act on the cannabinoid receptors present in presynaptic endings (32). They perform the following actions related to analgesia:

  • Decrease the release of neurotransmitters.
  • Activate descending inhibitory pain pathways.
  • Reduce postsynaptic sensitivity and alleviate neural inflammation.
  • Modulate CB1 receptors within central nociception processing areas and the spinal cord, resulting in analgesic effects.
  • Attenuate inflammation by activating CB2 receptors (32).
  • Emerging research shows cannabis is indicated for:
  • Migraines
  • chronic pain
  • back pain
  • arthritic pain
  • pain associated with cancer and surgery.
  • neuropathic pain
  • diabetic neuropathic pain when administered early in the disease progression.
  • sickle cell disease
  • cancer
  • inflammatory bowel disease (32)

 

Available Forms

Cannabis refers to products sourced from the Cannabis sativa plant. There are differences between cannabis, cannabinoids, and cannabidiol (CBD). Cannabinoids are extracted from the cannabis plants. Cannabinoid-based treatments, such as dronabinol and CBD, are typically approved medical interventions for specific indications. THC (9-tetrahydrocannabinol) is the psychoactive component of the cannabis plant. CBD is a non-psychoactive component (32).

 

Cannabis can be consumed in different forms, each with a different onset and duration. Patients may have individual preferences, including:

  • smoking/vaporizing dried flowers.
  • consuming edibles
  • tinctures or oils
  • applying topicals (32)

 

Dosing and Monitoring

Inhaling marijuana via the lungs by smoking or vaping causes maximum plasma concentration within minutes. Psychiatric effects begin within seconds to a few minutes after inhalation and peak after 15 to 30 minutes. The effect diminishes throughout 2 to 3 hours (32).

Oral ingestion of marijuana causes psychiatric effects that typically occur between 30 and 90 minutes and reach maximum effect after 2 to 3 hours. Ingested marijuana effects last about 4 to 12 hours (32).

Dosing cannabis is challenging due to variations in potency and individual responses. Start with low doses and titrate slowly to achieve the desired effect while minimizing side effects. Regular monitoring is crucial, including assessing symptom relief, adverse effects, and potential drug interactions. Encourage patients to keep a diary to track their cannabis use and its effects (32).

 

Side Effects and Contraindications

Cannabis can exacerbate mental health conditions such as anxiety and psychosis. Common side effects of cannabis include (32):

  • Dizziness
  • dry mouth
  • increased heart rate
  • impaired memory
  • psychoactive effects

 

Contraindications include:

  • Pregnancy
  • Breastfeeding
  • heart disease
  • respiratory conditions
  • history of substance abuse
  • mental health disorders

Case Study

Mary is agreeable to trying an increased dose of Gabapentin. Mary would also like to see a counselor to discuss her past and get help with her anxiety. You made an appointment for Mary to see a Licensed Clinical Social Worker in your clinic.

You read the side effects and warnings for Gabapentin, and it is unsafe to use Gabapentin and Tramadol together since they are both depressants. You order a non-steroidal drug for Mary's somatic knee pain and make a consult for imaging studies on her left knee. You also make a referral to Orthopedics.

You educated Mary about the side effects of Gabapentin and scheduled a follow-up appointment. The day after Mary began her treatment with the increased Gabapentin, you called Mary to follow up on its effect. Mary still has pain, but she is not having any untoward side effects. Gabapentin may not work immediately so you will schedule a follow-up call in 3 days.

Opioid Use, the Opioid Epidemic, and Statistics

The use and misuse of opioids has become a pressing public health concern, leading to a global epidemic. The history of opioid use, the opioid epidemic, and associated statistics provide essential context for healthcare professionals in addressing this public health crisis. More importantly, it is estimated that 1 in 4 patients receiving prescription opioids in primary care settings will misuse them. In addition, 50% of opioid prescriptions are written by primary care providers, including nurse practitioners (22). Understanding the factors contributing to the epidemic and the magnitude of its impact is crucial for effective prevention, intervention, and treatment strategies.

 

History of Opioid Use

Opioids have a long history of medicinal use, dating back to ancient civilizations. They have been a drug of choice for pain relief for thousands of years. The introduction of synthetic opioids in the 19th century, such as morphine and later heroin, revolutionized pain management. However, their potential for addiction and misuse soon became apparent (16).

 

The Opioid Epidemic

The opioid epidemic refers to the surge in opioid misuse, addiction, and overdose deaths. The epidemic gained momentum in the late 1990s with increased prescribing of opioids for chronic pain (43).

No doubt, increased prescribing put opioids in the hands of consumers, but increased prescribing resulted from a multifactorial influence. One of the main influences was aggressive marketing by pharmaceutical companies, which has been well publicized. However, due to the long history of underprescribing pain medications for fear of misuse and addiction, the medical community was primed to expand its opioid prescribing practices (31).

A historical event that increased comfort with prescribing opioids, in the writer's opinion, was the introduction of the Medicare Hospice Benefit in 1986. Medical directors must be contracted or employed by hospices, and these medical directors had or soon gained pain management expertise. To further promote hospice and effective pain management, the hospice medical directors, with newly acquired skills, provided education throughout medical communities about pain management and specifically to decrease the fear of using opioids. Pharmacies and attending physicians grew accustomed to giving opioids for home use. Hospice care is for terminally ill patients, defined as a life expectancy of 6 months or less. Still, the reality is that hospice discharges 12 to 40% of patients for ineligibility and other reasons.

A more prominent factor in increasing opioid prescribing was the 1996 American Pain Society's introduction of pain as "the 5th Vital sign." Soon after, The Joint Commission promoted pain as "the 5th Vital Sign" and began compliance surveys in healthcare organizations requiring pain assessment details to be as prominent as blood pressure and heart rate. The Joint Commission cited a quote from 1968 by a nurse from the University of California Los Angeles, Margo McCaffrey, who defined pain as "…Whatever the experiencing person says it is, existing whenever s/he says it does." The Joint Commission accreditation programs pursued pain management as part of the accreditation process throughout its healthcare accreditation programs, including hospice accreditation by 1989 per TJC Timeline (48).

The National Institute of Health published an article about the Joint Commission's role in the opioid epidemic, particularly regarding the definition of pain, "This definition emphasizes that pain is a subjective experience with no objective measures. It also stresses that the patient, not the clinician, is the authority on the pain and that their self-report is the most reliable indicator of pain. This set the tone for clinicians: Patients are always to be trusted to report pain accurately” (45).

 

Statistics on the Opioid Epidemic

In the United States alone, over 500,000 people died from opioid overdoses between 1999 and 2017. The number of opioid-related overdose deaths continues to increase, with synthetic opioids, mainly illicitly manufactured Fentanyl, playing a significant role in recent years (46). Fentanyl-laced drugs, such as marijuana, are increasingly sold knowing and unknowingly to introduce medications with a high addiction rate, thus creating new consumers. This practice can potentially increase deaths due to the imprecise nature of manufacturing (16).

Opioid-related hospitalizations have also risen substantially. In 2014, there were approximately 1.27 million hospitalizations related to opioids in the United States. These hospitalizations not only place a burden on healthcare systems but also reflect the severe consequences of opioid misuse (3).

Federal Regulations on Opioid Prescribing

The history of substance use disorder prevention that promotes opioid recovery and treatment for patients and communities can be traced back to the early 20th century. However, the current approach to addressing opioid addiction and promoting healing has evolved significantly in recent times (36).

In the early 1900s, health professionals treated opioid addiction with punitive measures, including incarceration and moralistic approaches. The focus was on punishing individuals rather than providing effective treatment. This approach persisted for several decades until the mid-20th century when the medical community started recognizing addiction as a medical condition rather than a moral failing (36).

The Controlled Substances Act (CSA), introduced in 1970, was a response to increasing drug abuse and illicit drug trafficking in the United States. The CSA is a federal law regulating the manufacture, possession, distribution, and use of certain substances, including drugs and medications, that can potentially cause abuse and dependence. Its primary purpose is to combat drug abuse, reduce drug-related crimes, and protect public health and safety. The Drug Enforcement Agency (DEA) plays a crucial role in enforcing the CSA by monitoring and controlling controlled substance production, distribution, and use (31).

In the 1990s, the significant increase in opioid prescribing, leading to a surge in opioid addiction and overdose deaths, prompted a shift in focus toward prevention. Efforts were made to educate healthcare providers about the risks of overprescribing opioids and to implement prescription drug monitoring programs to track and prevent abuse (36).

The Comprehensive Addiction and Recovery Act (CARA) was signed into law in 2016 to expand access to treatment and recovery services for opioid addiction. This legislation allocated funding for prevention, treatment, recovery, and support services while promoting evidence-based practices and programs (36).

The Centers for Disease Control and Prevention (CDC) published guidelines in 2016 for prescribing opioids for chronic pain, which was updated in 2022. These guidelines emphasize the importance of non-opioid alternatives, using the lowest effective dose for the shortest duration, and assessing the benefits and risks of continued opioid therapy (13).

Furthermore, the Substance Use Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act (SUPPORT) was signed into law in 2018, providing additional resources to address the opioid crisis. This legislation expanded access to medication-assisted treatment (MAT), increased the availability of naloxone, a medication used to reverse opioid overdose, and enhanced support for recovery housing (36).

In recent years, there has been a growing recognition of the importance of a comprehensive approach to opioid addiction, including harm reduction strategies, increased access to naloxone, and the integration of mental health services. Communities and organizations have been working together to address the underlying issues contributing to addiction, such as poverty, trauma, and social determinants of health (50).

Overall, the history of substance use disorder prevention that promotes opioid recovery and treatment has evolved from a punitive approach to a more compassionate and evidence-based model. Efforts are now focused on prevention, early intervention, and expanding access to comprehensive treatment and support services for individuals and communities affected by opioid addiction (36).

The most current federal regulations on opioid prescribing for healthcare providers are the amendments to the CSA in 2018, which added new rules to limit the quantity and duration of opioid prescriptions for acute pain to seven days. In 2022, the CDC updated recommendations to the Clinical Practice Guidelines for Prescribing Opioids for Pain.

The 2022 CDC guidelines are summarized below (13):

  1. Non-opioid therapies should be considered the first-line treatment for chronic pain.
  2. Establish clear treatment goals with patients, including realistic pain management and functional improvement expectations.
  3. Conduct a thorough risk assessment for potential harms before initiating opioid therapy.
  4. When opioids are used, start with the lowest effective dose and consider immediate-release opioids instead of extended-release or long-acting opioids.
  5. Prescribe the lowest effective dose for the shortest duration possible, typically three days or less and rarely exceeding seven days.
  6. Reassess benefits and risks within one day after prescribing opioids, including checking the prescription drug monitoring database.
  7. Avoid prescribing opioids and benzodiazepines concurrently whenever possible due to the increased risk of overdose and death.
  8. Offer naloxone to patients at increased risk of opioid overdose, including those with a history of overdose, substance use disorder, or concurrent benzodiazepine use.
  9. When opioids are no longer needed, taper the dose gradually to minimize withdrawal symptoms.
  10. Arrange an evidence-based treatment for patients with opioid use disorder, including medication-assisted treatment (Naltrexone, Buprenorphine, or Methadone).

Safe Prescribing and Prescription Monitoring Program

Prescription Drug Monitoring Programs (PDMP) are state-run electronic databases that track.

the prescribing and dispensing of controlled substances. PDMPs are designed to improve patients.

care and safety by giving clinicians access to patients' prescription histories, allowing them to make informed decisions when prescribing controlled substances. PDMPs help identify patients at risk of substance misuse or prescription drug overdose. They also enable clinicians to identify potential drug interactions and prevent opioid diversion (14).

PDMPs collect and store data from pharmacies and prescribers in a centralized database. Clinicians can access this database to review a patient's prescription history, including the types of medications prescribed, the prescribers involved, and the dispensing pharmacies (14).

In many states, PDMP use is mandated by law, and nurse practitioners may be required to register and use the system. It is essential to understand state-specific laws and regulations regarding PDMP use.

PDMPs have some limitations, such as incomplete data or delays in reporting. The CDC emphasizes that clinicians should use PDMP data for their clinical assessment and other relevant information to make informed decisions about prescribing controlled substances. Still, PDMP cannot be used as the sole basis for denying or providing treatment (14).

 

Case Study

After five days on Gabapentin, Mary was doing well, and her neuropathic pain had decreased to 3/10. However, Mary suffered a fall after her knee "gave out" and injured her knee and back. She was in severe pain, and her family drove her to the ER. The ER doctors saw Mary, and orthopedics were consulted. Mary has surgery scheduled for a knee replacement a week from now.

Mary was prescribed Vicodin because she was in excruciating pain, but her prescription only allowed enough medication for two days. Mary has made an appointment with you to renew her prescription.

You evaluate Mary because you know that concomitant use of Gabapentin and opioids puts Mary at risk for respiratory depression and possible side effects, including accidental overdose.

Mary stated she has been more alert the past 24 hours and is afraid her functional status will continue to decline if she does not have more Vicodin because the pain in her back and knee makes it difficult to stand. You assess Mary. Mary stated she occasionally drinks alcohol but has not had a drink since she moved. She has no familial history of substance abuse or mental health disorders.

Mary's mother stayed at her house to help her for the first 24 hours after Mary's return from the ER, but Mary is providing her care now.

You check the PDMP database and see that Mary was prescribed eight pills she has taken over the last 48 hours.

Since the Vicodin has been effective without untoward side effects, and Mary's function is improving, you decide to refill the prescription of Vicodin. You will taper the dose to three Vicodin daily for two days and two for one day. Mary will be near her appointment for a knee replacement as well.

Preventing Opioid Use Disorder

As previously discussed, opioid addiction is a growing concern worldwide, affecting individuals from all walks of life. According to the CDC, "Anyone who takes prescription opioids can become addicted to them" (14).

As frontline healthcare professionals, nurse practitioners must recognize the signs of opioid addiction to provide timely intervention and support. This section will outline the key indicators of opioid addiction.

 

Physical Symptoms

Physical symptoms are often the first noticeable signs of opioid addiction. These symptoms may include constricted pupils, drowsiness, slurred speech, impaired coordination, and increased sensitivity to pain. Additionally, individuals struggling with opioid addiction may exhibit frequent flu-like symptoms, such as a runny nose, sweating, itching, or gastrointestinal issues.

 

Behavioral Changes

Opioid addiction can significantly impact an individual's behavior. These may include increased secrecy, frequent requests for early prescription refills, doctor shopping (seeking prescriptions from multiple healthcare providers), neglecting personal hygiene, and experiencing financial difficulties due to excessive spending on opioids (37).

 

 

 

 

Social Isolation

Opioid addiction often leads to social withdrawal and isolation. Individuals struggling with opioid addiction may distance themselves from family, friends, and social activities they once enjoyed. They may exhibit erratic mood swings, become defensive or hostile when confronted about their drug use, and display a general lack of interest in previously important activities (30).

 

Psychological Changes

The psychological impact of opioid addiction is significant. Individuals with opioid addiction may exhibit increased anxiety, depression, irritability, and restlessness. They may also experience cognitive impairments, memory lapses, and difficulties in decision-making. Healthcare professionals should be attentive to these changes, as they can indicate opioid addiction (51).

 

Tolerance and Withdrawal Symptoms

The development of tolerance and withdrawal symptoms are critical signs of opioid addiction. Individuals may require increased dosages of opioids to achieve the desired effect, indicating a growing tolerance. Furthermore, withdrawal symptoms such as muscle aches, nausea, vomiting, insomnia, and intense cravings for opioids may occur when the drug is discontinued or reduced abruptly (51).

Opioid Overdose

The management of opioid overdose, withdrawal, and addiction requires a comprehensive approach that combines pharmacological interventions with psychosocial support. Naloxone remains a vital tool for reversing opioid overdose, while medications such as Methadone, buprenorphine, and naltrexone play crucial roles in withdrawal and addiction treatment (National Institute of Health, 2023). Nurse practitioners must stay vigilant and informed about the evolving landscape of medications. This section aims to provide a comprehensive review of medications and treatment strategies for opioid overdose, withdrawal, and addiction and is excerpted from the NIH (40).

 

Naloxone
Mechanism of Action and Metabolism

Naloxone is an opioid receptor antagonist. It works by binding to opioid receptors and displacing any opioids present, thereby reversing the effects of opioid overdose. It has a higher affinity for opioid receptors than most opioids, effectively blocking their action.

Naloxone is indicated for emergency intervention of opioid overdose. It effectively reverses respiratory depression and other life-threatening effects. Studies suggest the potential benefits of combining naloxone with other medications, such as buprenorphine (see below), to improve outcomes. Initiatives promoting community-based naloxone distribution programs have shown promising results in reducing opioid-related deaths.

 

Available Forms

Naloxone is available in various formulations:

  • Intranasal
  • Intramuscular
  • Intravenous
  • auto-injectors.

 

The most used form is the intranasal spray, which is easy to administer and requires no specialized training. Intranasal naloxone formulations have gained popularity due to their ease of use and increased availability. A recent study showed that the non-FDA-approved compound spray was far less effective than either FDA compound (15).

 

Dosing and Monitoring

The recommended initial dose of naloxone for opioid overdose is 2mg intranasally or 0.4mg to 2mg intramuscularly or intravenously. If the patient does not respond within 23- minutes, additional doses may be administered every 2-3 minutes. Continuous monitoring of the patient's respiratory status is essential, as repeat doses may be required due to the short half-life of naloxone.

 

Side Effects and Contraindications

Naloxone has been shown not to affect individuals without opioids in their system.

 

Common side effects of naloxone include
  • Withdrawal symptoms: increased heart rate, sweating, and agitation
  • nausea
  • vomiting
  • headache

Contraindications include known hypersensitivity to naloxone and situations where the use of naloxone may be unsafe or not feasible.

 

Considerations for Nurse Practitioners

Fentanyl and other opioids have a rapid onset, and the need to act quickly is paramount. As mentioned previously, the ease of use and higher plasma concentrations using the FDA-approved 4-mg FDANxSpray device compared with the locally compounded nasal sprays should be considered when ordering Naloxone (15).

Fentanyl and other potent synthetic opioids may require multiple administrations of naloxone to achieve reversal of an overdose (Chiang, Gyaw, & Krieter, 2019). As a nurse practitioner prescribing naloxone, it is crucial to assess the patient's risk factors for opioid overdose, such as a history of substance use disorder or chronic pain management. Education regarding the proper administration of naloxone should be provided to the patients and their caregivers. Additionally, it is essential to provide resources for follow-up care, including addiction treatment and ongoing support.

 

Methadone
Mechanism of Action and Metabolism

Methadone is a long-acting opioid agonist that effectively suppresses withdrawal symptoms and reduces cravings. It binds to the same opioid receptors in the brain as other opioids. It relieves withdrawal symptoms and reduces cravings by blocking the euphoric effects of opioids, thus helping individuals with opioid dependence to achieve stability (33).

 

Available Forms

Methadone is available in oral tablets and liquid formulations. The oral tablet is the most used form and is typically administered once daily (33).

 

Dosing and Monitoring

Methadone dosing is individualized based on the patient's response and needs. Initially, the dose often started low and gradually increased until the patient reached a stable dose. Dosing may need to be adjusted based on the patient's response, adherence, and any changes in their overall health. Regularly monitoring the patient's vital signs, urine drug screens, and assessment of their withdrawal symptoms and cravings is essential.

 

Side Effects and Contraindications

Common side effects of methadone include:

  • Constipation
  • dry mouth
  • drowsiness
  • sweating
  • weight gain
  • respiratory depression

 

Contraindications include:

  • known hypersensitivity to methadone
  • severe asthma
  • respiratory depression
  • certain heart conditions (33).

 

Considerations for Nurse Practitioners

As a nurse practitioner prescribing methadone, conducting a comprehensive assessment of the patient's medical history, current medications, and substance use history is crucial. Opioid treatment programs or specialized clinics are often involved in methadone treatment, so collaboration and coordination of care with these programs are essential. Regularly monitoring the patient's progress, adherence, and potential side effects or drug interactions is essential. Additionally, providing education on the risks and benefits of methadone and the importance of adherence to the prescribed regimen is crucial for successful treatment outcomes.

 

Buprenorphine
Mechanism of Action and Metabolism

Buprenorphine is a partial opioid agonist with a ceiling effect that minimizes the risk of overdose while reducing withdrawal symptoms. Buprenorphine is a partial opioid agonist that binds to the same receptors as other opioids but produces a weaker response. It has a high affinity for the mu-opioid receptors, which helps reduce cravings and withdrawal symptoms in individuals with opioid dependence.

 

Available Forms

Buprenorphine is available in different formulations, including sublingual tablets, buccal films, and extended-release injections. The sublingual tablets have different strengths, such as 2mg, 4mg, 8mg, and 12mg. Buprenorphine is taken as a daily tablet or weekly or monthly injection.

 

Dosing and Monitoring

The dosing of buprenorphine varies depending on the individual's opioid dependence severity and treatment phase. Initially, a low dose (e.g., 2-4mg) is given, and it may gradually increase to a maintenance dose of 8-24 mg daily. Regular monitoring is essential to assess the patient's response, adherence, and potential side effects.

 

Side Effects and Contraindications

Common side effects of buprenorphine include:

  • Constipation
  • Nausea
  • Headache
  • Insomnia
  • Sweating

 

Serious side effects are rare but can include:

  • Respiratory depression
  • Allergic reactions

 

Buprenorphine is contraindicated in individuals with:

  • Severe respiratory insufficiency
  • Acute intoxication with opioids
  • Known hypersensitivity

 

Considerations for Nurse Practitioners

Nurse practitioners can prescribe buprenorphine for opioid dependence treatment under the Drug Addiction Treatment Act (DATA). To become eligible, they must complete specific training requirements and obtain a waiver from the Substance Abuse and Mental Health Services Administration (SAMHSA). Nurse practitioners should assess patients thoroughly, including their opioid use history, comorbidities, and medication compatibility, while ensuring appropriate counseling and referral for comprehensive treatment (40).

 

Clonidine + Lofexidine
Mechanism of Action and Metabolism:

Both Clonidine and Lofexidine are alpha-2 adrenergic agonists. They work by stimulating alpha-2 receptors in the brain, which reduces sympathetic outflow and norepinephrine release. This results in decreased sympathetic activity, leading to various effects such as reduced blood pressure, decreased heart rate, and alleviated withdrawal symptoms (28).

 

Available Forms

Clonidine is available in oral tablets and patches. Lofexidine is available in oral tablets and is taken as needed (40).

 

Dosing and Monitoring

For opioid withdrawal, the Clonidine dose ranges from 0.1-0.3 mg every 4-6 hours. Lofexidine is usually initiated at 0.53 mg three times daily, and the dose can be increased to 2.88 mg daily. Monitoring blood pressure and heart rate is essential during treatment (40).

 

Side Effects and Contraindications:

Common side effects of both medications include:

  • dry mouth
  • sedation
  • dizziness
  • constipation
  • orthostatic hypotension (40).

 

Both medications are contraindicated in patients with:

  • Hypotension
  • Bradycardia
  • heart block
  • history of hypersensitivity to the drugs (40).

 

Considerations for Nurse Practitioners:

An early study of lofexidine vs. clonidine for withdrawal symptoms showed that treatment with lofexidine resulted in lower withdrawal symptoms, fewer mood problems, less sedation, and hypotension. There were no significant differences in craving levels, morphine metabolites in urine, or dropout rates when both were compared.

Lofexidine can be a safe option for outpatient treatment as it does not lead to hypotension. However, nurse practitioners must closely monitor patients' blood pressure and heart rate during treatment and educate them about possible side effects. If patients experience any concerning symptoms, they should inform their nurse practitioner immediately.

Gradual dose reduction of Clonidine is crucial to prevent rebound hypertension. Before prescribing either medication, nurse practitioners should assess for any contraindications or potential drug interactions (19).

 

Emerging Therapies for Withdrawal

Extended-release naltrexone: Naltrexone is an opioid receptor antagonist that blocks the effects of opioids, reducing the risk of relapse. It is taken as a monthly injection.

Alpha-2 adrenergic agonists: Emerging evidence suggests the potential use of dexmedetomidine and guanfacine for managing opioid withdrawal symptoms.

 

 

Medication-Assisted Treatment (MAT):

Methadone was introduced in the 1960s and marked a significant turning point in opioid addiction treatment or MAT. Along with counseling and behavioral therapies, MAT became the cornerstone of opioid addiction recovery.

 

Examples of medications used:

  • Methadone
  • Buprenorphine:
  • Naltrexone:

 

Adjunctive Pharmacotherapies:

Antidepressants: Selective serotonin reuptake inhibitors and tricyclic antidepressants may help manage co-occurring depression and anxiety.

 

Anticonvulsants:

Medications like Gabapentin and pregabalin show promise in reducing opioid cravings and improving treatment outcomes.

Drug Diversion and Illegal opioids

Misuse of opioids is facilitated by diversion and is defined as "the transfer of drugs from lawful to unlawful use" (24). Most commonly, this occurs when family and friends share prescribed opioids with other family and friends. Opioids and other controlled drugs are also diverted from healthcare facilities. Statistics show that healthcare facility diversion has increased since 2015 (24)

Diversion affects patients, healthcare workers, healthcare facilities, and public health. Patients experience substandard care due to ineffective pain management and impaired healthcare workers. In addition, affected patients are at risk of infections from compromised syringes (24).

Healthcare employees who divert are at risk of overdose and death. If caught, they face criminal prosecution and malpractice suits. Healthcare facilities also bear the cost of diverted drugs via internal investigations, follow-up care for affected patients, regulatory fines for inadequate safeguards, and declining public trust (24).

Despite the enormous consequences of drug diversion, healthcare facilities have implemented few processes to detect and deter the diversion of controlled substances (24).

Patient Teachings and Considerations

Opioids have significant side effects and carry a risk of addiction and overdose. Nurse practitioners can decrease the risks of misuse and addiction by educating patients on appropriate disposal, safe storage, and potential signs of addiction. Taking additional time to provide teaching nurse practitioners can promote patient safety, informed decision-making, and responsible opioid use.

 

Safe Storage and Disposal:
  • Teach patients to store opioids securely, out of reach of children, pets, visitors, and non-caregiver family members, to prevent accidental ingestion or misuse (13). Only the caregiver, if applicable, or the patient should have access to pain medications.
  • Instruct patients on proper disposal methods, such as using drug take-back programs or mixing opioids with undesirable substances (e.g., coffee grounds) before throwing them away (11) (13).

 

Medication Adherence:
  • Emphasize the importance of taking opioids as prescribed, at the correct dose and frequency, to achieve optimal pain relief.
  • Encourage patients to notify their healthcare provider if they experience inadequate pain control or side effects (35).

 

Potential Side Effects:
  • Educate patients about common side effects of opioids, including constipation, nausea, sedation, and respiratory depression.
  • Discuss strategies to manage side effects, such as maintaining adequate hydration, consuming a fiber-rich diet, and using over-the-counter laxatives as needed (11).

 

Risk of Dependence and Addiction:
  • Explain the potential for opioid dependence and addiction, especially with long-term use or a history of substance abuse.
  • Encourage patients to promptly report signs of opioid misuse, such as craving, loss of control, or continued use despite negative consequences (51).

 

 

 

 

Avoiding Alcohol and Other Central Nervous System Depressants:
  • Instruct patients to avoid consuming alcohol or other medications that can enhance the sedative effects of opioids, increasing the risk of respiratory depression.
  • Advise patients to contact the Nurse Practitioner before starting new medications, including over-the-counter drugs or herbal supplements (2).

 

Driving and Operating Machinery:
  • Inform patients about the potential impairment caused by opioids, including reduced alertness, reaction time, and coordination.
  • Advise patients to avoid driving or operating heavy machinery while taking opioids until they know how the medication affects them (14).

Case Study

You take some extra time with Mary to educate her on the taper dose of Vicodin, the potential for harm, and the risk of opioids, especially when used concomitantly with Gabapentin. You let Mary know it is unsafe to use alcohol, not only with Vicodin but also with Gabapentin. You let Mary know that Vicodin has a risk of dependency and misuse and, therefore, she will be monitored carefully. You also educate that Mary should store the Vicodin away from visibility by anyone but herself since she can self-administer her medication. You let Mary know that Vicodin can cause constipation and that she should increase her water intake and take a stool softener.

You ask Mary to call you if her pain is not adequately relieved or if her medications run out before the three days.  

You let Mary know that if she does stop taking the Vicodin before she has completed all the medication, she should dispose of it by mixing the pills with liquid and coffee grounds to make them unpalatable to animals and others.

Mary complied with your education, completed her course of Vicodin, and was scheduled for surgery. Mary's social worker helped her communicate with her new employer and delayed her start date until after her recovery.

During her recovery, Mary received physical therapy and a short course of pain medication managed by her orthopedist.

Mary returned to the clinic for a follow-up visit after completing her therapy and before starting work. Mary's pain level in her knee is 3/10, and she already feels like she can walk further than pre-surgery. Gabapentin has continued to help Mary's neuropathic pain in her back, and she reports 2/10. Mary looks forward to beginning her new job and is optimistic about the future.

Conclusion

Pain management is the leading cause of primary care appointments and chronic pain is the leading cause of disability. Yet, prescribing opioids for primary care patients is also a factor in drug misuse and the opioid epidemic. Nurse practitioners are challenged to appropriately treat pain and effectively control diversion, addiction, and death from overdose.

It is imperative that nurse practitioners use evidence-based practices to assess, appropriately intervene, and educate about the benefits and potential harm caused by treatment with opioids. Nurse practitioners must stay up to date with the current federal regulations regarding PDMPs, clinical prescribing guidelines, and emerging treatments for pain and opioid abuse disorders.

 

 

Tirzepatide for Type 2 Diabetes and Weight Management

Introduction   

The emergence of the drug tirzepatide is becoming more popular and widespread and is being utilized among those with diabetes and also those who desire to lose weight. It is one of the newest diabetic drugs given by injection that also triggers dramatic weight loss in those who use the injections.

The U.S. Food and Drug Administration (FDA) approved tirzepatide in 2022 for individuals with diabetes, particularly Type 2 Diabetes. The FDA officials have not approved tirzepatide yet for weight loss, but they are currently tracking the medication and may have a recommendation for its approval by the end of this year. Clinical trials have shown that individuals with an elevated body mass index (BMI) and who did not have diabetes lost a considerable amount of weight when they received tirzepatide (1).

Advanced Practice Registered Nurses (APRNs) need to understand how to safely prescribe tirzepatide and the reasoning as to why it causes weight loss for specific individuals.

Drug Classification

Tirzepatide is part of a class of medications called glucose-dependent insulin tropic polypeptide (GIP) receptor and glucagon-like peptide-1 (GLP-1) receptor agonists. It comprises a 39 amino acid linear synthetic peptide conjugate to selective receptor agonists in preclinical and clinical trials.

Tirzepatide is used for treating Type II diabetes in adults as an adjunct to diet and exercise. It is also used for weight loss in some individuals and has gained increased attention as a new therapeutic agent for glycemic and weight control.

Social media has had a significant influence and increased the desire to use tirzepatide, and while individual results vary, the weight loss in adults ranged from 12 – 25 pounds.

Online pharmacies, diet clinics, and medical spas are implementing thousands of ads on social media to capitalize on a surge of interest in the drug.

  1. Why has there seemed to be an increase in patients requesting this medication? What other medicines intended for type 2 diabetes are also being used for weight loss management?
  2. What are the ethical considerations regarding marketing this drug for weight loss when its primary use is for type 2 diabetes? Could this impact supply and costs?

Indications of Usage

The use of tirzepatide is being used for both Type II diabetes and weight control in certain patients. It has been a game changer for people living with Type II diabetes. The drug’s primary use is as an adjunct to diet and exercise to improve glycemic control in adults with diabetes.

The drug has also proven beneficial for weight loss in patients experiencing obesity, and those who are taking the highest dosage have shared a body weight reduction of 15.7% (2). Tirzepatide is an injectable prescription medication used together with diet and exercise, and it is not yet known if it can be used safely with patients who have had pancreatitis.

It is important to remember that it is not to be used for patients with Type I diabetes, but it is safe for Type II diabetic patients. Also, the safety of tirzepatide has yet to be discovered for children and those under 18; therefore, the medication should not be used for this age group.

In studies conducted with or without diabetic medicines, 75% – 90% of patients taking tirzepatide reached an overall A1C of less than 7% with an average starting A1C of 7.9 – 8.6% across the following dosages – 5mg, 10mg, and 15mg. The study results were measured at weeks 40 and 52 (3).

  1. What dietary and activity recommendations can you provide to patients using tirzepatide for weight loss?
  2. Is this drug intended for those who want to lose 5-10 pounds?

Use of Tirzepatide with Diabetic Patients

Tirzepatide can be used for patients with Type II diabetes in combination with a diabetic-friendly diet and exercise. The drug works by lowering the patient’s overall blood sugar and also improves the A1C results of patients over some time. The injection has been approved by the FDA to treat Type II diabetes and is administered once weekly (4).

It is considered the first in a new class of medications – a dual glucose-dependent insulin tropic polypeptide (GIP) and glucagon-like-peptide-1 (GLP-1) receptor antagonist. The mechanism of how it works mimics two gut hormones (GIP and GLP-1). These hormones are essential in how patients digest food and regulate blood glucose after meals. The hormones also play a role in making individuals feel fuller and curb specific food cravings.

The provider can prescribe tirzepatide before attempting other diabetic medications if a patient has a BMI of 30 or greater or 27 or greater with weight-related conditions and if the drug is combined with a personalized weight loss plan that addresses physical activity, nutrition, and lifestyle changes.

However, due to the cost and some insurance companies not covering the injection unless the patient has both diabetes and obesity, the provider must carefully consider prescribing this medication.

 

 

 

 

Case Study

The patient states this ‘miracle drug’ is worth paying for out of pocket!

Jeff Capron, a 53-year-old Boonville, New York, web developer, started taking tirzepatide in December 2022. His friend had reported good results with the medication, so Jeff looked into the research studies behind it and then spoke with his primary physician.

The physician said, “Yeah, let’s give it a shot,” even though he did not have much experience with it. The physician did not have an opinion one way or the other than looking at the data set and seeing no reason why they could not try it.

Jeff’s hemoglobin A1C went from 10.1% to 6% in 3 months, which was very promising. “I never had that kind of experience with any medication for diabetes.” There is a range in how much A1C reduction people experience with tirzepatide, but many people taking it can get their A1C under 7% — an ideal goal for people with Type 2 diabetes.

Jeff experienced constipation and a little trouble sleeping early, but both issues disappeared quickly. He says, “I wake up in the morning, and my fasting blood sugars are normal.”

The medication took effect, he says, within 12 hours. He compared the feeling to having a gastric bypass.

“You cannot overeat food. As soon as you overeat, you almost feel ill.” While it generally takes a few months to notice effects like A1C reduction and significant weight loss, side effects such as lower appetite may be felt immediately.

Weight loss was not his primary goal, but he lost about 35 pounds on the medication in the first five months. He also lost his sweet tooth. “I can maybe count three sweet things I have eaten since December.”

Jeff found that his appetite slowly recovered days after taking tirzepatide. “You take the shot every Sunday, and by Saturday, you start to get a lot of appetite,” he says. “It does not seem to affect your weight. If I eat a little bit more on Saturday night, on Sunday, the scale will not move one way or the other.”

Jeff is allergic to hornets, so he already carries an auto-injector. He was not worried about using another drug delivered through a needle. “It’s just a push button,” he says. It also helped that his wife is a nurse. “So, I had her with me the first time to ensure I was doing it right. I didn’t even feel it.”

When Jeff was first prescribed tirzepatide, his insurance covered it. The company has since removed that benefit. He has filed an appeal but pays about $1,000 monthly out of pocket for his weekly injections. He plans to keep paying as long as necessary.

He considers the financial burden well worth it. “I have never had a medication that worked as well before for chronic conditions,” Jeff says. “I’ve been blown away by it. For me, it’s a miracle drug. It got rid of my diabetes” (4).

Use of Tirzepatide for Weight Loss Management

As mentioned, this medication is indicated for patients with a BMI of >30 or a BMI of >27 with qualifying comorbidities. Obesity can become a chronic lifetime disease, and for conditions such as these, the patient needs to implement therapy for the lifetime of the disease.

In a study conducted for tirzepatide, there was a dramatic increase in effectiveness compared to traditional nonsurgical interventions such as diet, exercise, and lifestyle changes. However, it has been noted that taking tirzepatide on an ongoing basis is recommended and necessary to maintain any weight loss achieved from the medication.

If a patient stops taking the drug, likely, it will no longer work (5).

Public health officials have expressed concerns about using the drug long-term. Still, data is currently lacking regarding long-term effectiveness, treatment duration, and maintaining weight reduction once the therapy is discontinued.

A recent trial consisted of 783 participants with a BMI greater than 30, and these participants agreed to take either a 10mg or 15mg dose of tirzepatide over 36 weeks. The injection is given once weekly, so this would equal a total of 36 injections.

By the end of 36 weeks, participants lost more than 21% of their body weight. After 36 weeks, participants continued on tirzepatide or received placebo treatment for the following year. The patients needed to be made aware of which treatment they were receiving.

Those still taking tirzepatide injections weekly after 88 weeks lost an additional 7% of their body weight, and those taking the placebo regained 15% at the end of 88 weeks (5).

Common Side Effects and Contraindications

Side Effects

Patients vary immensely with different experiences and side effects related to tirzepatide; however, the following are the most common side effects experienced by those taking the medication:

  • Nausea
  • Decreased appetite
  • Vomiting
  • Diarrhea
  • Indigestion
  • Constipation
  • Stomach Pain

 

Tirzepatide usually does not cause fatigue, leaving one feeling weak, tired, and low energy. However, fatigue can be a common side effect of Type II diabetes.

It is important to note that most individuals who experience nausea, vomiting, and diarrhea episodes do so while the dosage increases, and typically, the symptoms decrease over time. G.I. effects were more prominent in those taking tirzepatide than those taking the placebo. The individuals not in the placebo group were more likely to stop treatment due to the unpleasant side effects (3).

Contraindications

Tirzepatide may cause thyroid tumors, including thyroid cancer, and it is essential to watch for possible symptoms, such as swelling or a lump in the neck, hoarseness, shortness of breath, or trouble swallowing.

Tirzepatide should also not be prescribed to any patient with Type 1 Diabetes.

One of the main ways that tirzepatide works is by stimulating the release of insulin from the pancreas, and due to this fact, there have not been many studies and clinical trials that include those with Type I diabetes.

However, this is not to say that prescribers have never ordered tirzepatide for those with Type I diabetes. Still, it is essential to note that if prescribed, it would be in addition to traditional insulin therapy.

  • Personal or family history of a type of thyroid cancer known as medullary thyroid carcinoma (MTC).
  • Any history of Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
  • Patients who are allergic to the actual medication or any of its ingredients.

Safe Prescribing Practices, Guidelines, and Considerations for Providers

Safe Prescribing Practices

As with all prescribed medications, safe standards of care must be implemented and followed to ensure patient safety is maintained. The same applies to providers considering prescribing tirzepatide, and specific criteria must be met beforehand. The following information discusses guidelines involving exclusion and inclusion criteria for providers to prescribe tirzepatide (6) accurately.

 

Guidelines

Exclusion Criteria – If present, the following indicates that the patient should not receive tirzepatide:

  • Diagnosis of Type I diabetes
  • Personal or family history of medullary thyroid carcinoma or with Multiple Endocrine Neoplasia syndrome type 2
  • Severe gastrointestinal dysmotility
  • History of pancreatitis
  • Pregnancy
  • Proliferative Diabetic Retinopathy (PDR), severe Nonproliferative Diabetic Retinopathy (NDR), clinically significant myalgic encephalomyelitis (M.E.), or diabetic macular edema (DME) unless the risks/benefits have been discussed with the patient and are documented in the patient's health record along with monitoring plans and follow-up with an eye specialist who is informed at the time of initiation.

 

Inclusion Criteria – All of the following must be met for tirzepatide to be prescribed:

  • Diagnosis of Type II diabetes
  • A BMI of 25 or greater
  • Inadequate glycemic control on at least 1mg of semaglutide injection plus two or more glucose-lowering drugs
  • Change needed to achieve goal A1C is less than 1%.
  • Goal A1C should be based on those recommended in the Diabetic Guidelines.
  • Adherence to current diabetic medications as evidenced by a review of the prescription refill history during the six months.

 

Additional Inclusion Criteria – All of the following must be met for tirzepatide to be prescribed:

  • Patients with atherosclerotic cardiovascular disease or chronic kidney disease
  • Patients of childbearing potential who are using oral contraceptives

 

Inclusion Criteria for Weight Loss

  2. What impact can tirzepatide have on a person with a healthy weight and BMI of <25?

 

Considerations for Providers

There are specific considerations that prescribers must be aware of when contemplating if a patient should receive the medication tirzepatide. The following is imperative and must be considered each time the medication is prescribed to a patient:

  • Clinical Indications – indicated for treating adults with insufficiently controlled diabetes mellitus as an add-on therapy to diet and exercise; as monotherapy when metformin is considered inappropriate due to contraindications or intolerance; and other medicinal products for treating Type II diabetes.
  • Monitoring of medication – routine monitoring of serum calcitonin or thyroid ultrasound is of uncertain value but is recommended for early detection of Medullary Thyroid Cancer (MTC).
  • Cost – the average price for tirzepatide ranges from $1,071-$1,351 without any coupons or insurance. Savings Card – manufacturer provided; patients can pay as little as $25 monthly for up to 12 injections. Savings Card – manufacturer provided; patients can pay as little as $25 monthly for up to 12 injections.
  • Benefits and Risks – One must evaluate the effectiveness of diabetes and the weight loss experienced. Some of the risks must be evaluated, such as increased cost of medication, unpleasant gastrointestinal side effects, poor insurance coverage, and drug shortages. The FDA has warned that the medicine can cause thyroid C-cell tumors in rats, and it is not sure whether tirzepatide causes similar tumors.

 

How long does it take for tirzepatide to begin working?

Tirzepatide will start to lower one's blood sugar levels immediately, but it can take 8 to 12 weeks to reach one's target A1C goal.

Compared to other diabetic treatments, studies have shown that it can take eight weeks to reach an A1C target of less than or equal to 7% and 12 weeks to get an A1C of less than or equal to 6.5%. Significant weight loss can occur as early as 28 weeks.

 

Safe Administration

It is essential to follow the correct steps for safe administration of tirzepatide as listed below:

  • The recommended starting dosage is 2.5mg, injected subcutaneously once weekly. The 2.5mg dosage is for treatment initiation and not for glycemic control.
  • After four weeks, increase the dosage to 5mg, injected subcutaneously once weekly.
  • If additional glycemic control is needed, increase the dosage in 2.5mg increments after at least four weeks on the current dose.
  • The maximum dosage is 15mg, injected subcutaneously once weekly.
  • If a dose is missed, instruct patients to administer it as soon as possible, within four days (96 hours) after the missed dose. If more than four days have passed, skip the missed dose, and administer the next dose on the regularly scheduled day. In each case, patients can then resume their regular once-weekly dosing schedule.
  • The day of weekly Administration can be changed, if necessary, as long as the time between the two doses is at least three days (72 hours).
  • Before initiation, train patients and caregivers on proper injection techniques.
  • Instruct patients using the single-dose vial to use a syringe appropriate for dose administration (e.g., a 1ml syringe capable of measuring a 0.5 mL dose).
  • Administer the medication once weekly, any time of day.
  • Inject the medication subcutaneously in the abdomen, thigh, or upper arm.
  • Rotate injection sites with each dose.
  • Inspect the medication visually before use. It should appear clear and colorless to slightly yellow. Do not use the medicine if particulate matter or discoloration is seen.
  • When using the medication with insulin, administer it as separate injections and never mix. It is acceptable to inject tirzepatide and insulin in the same body region, but the injections should not be adjacent.

 

Does the tirzepatide injection hurt when administered?

Pain from the injection site has not been reported as a common side effect, but it may occur.

Due to the injection being given subcutaneously, slight pain or discomfort can occur.

Alternatives to Tirzepatide for Weight Loss Management

In some instances, patients need to be aware of alternatives to tirzepatide in case they cannot take the actual injection for whatever reason. In cases such as these, there are alternative supplements that can be purchased over the counter, and they include the following (7):

  • PhenQ – top OTC choice – comprehensive weight loss solution that targets specific body regions, facilitates prompt fat loss, and expedites the weight loss journey.
  • PhenGold – the most potent OTC weight loss alternative – one of the top weight loss supplements that boost metabolism, making one less hungry, less tired, and an overall improved feeling.
  • Capsiplex BURN – the best choice for men – helps to burn fat faster and keep blood sugar levels in check. It helps to keep one's muscles, curbs hunger, gives one more energy, and torches stubborn fats.
  • Trimtone – the best choice for women – helps women to lose weight, eat less, increase metabolism, burn extra calories, and boost energy.
  • Prime Shred – best fat burner for men – boosts metabolism, keeps muscles intact, increases energy, and helps maintain focus.

 

The advanced practicing nurse or prescriber needs to inform patients about alternative options such as these in an effort for individuals to understand that other choices are available and can be used. Many individuals need to be more knowledgeable about alternatives besides tirzepatide due to the extra hype from social media sources that promote advertisements related to tirzepatide only but do not mention the other options.

 

Why does social media influence and encourage patients to take tirzepatide?

Social media trends can be helpful but can also become harmful by setting unrealistic expectations and promoting a diet culture mentality. They can create an unhealthy obsession with "clean" eating, especially in the younger populations.

Due to this, many individuals take the medication despite any occurrence or history of Type II diabetes, and the drug can ultimately become misused.

It has been noted that there is an influx of patients requesting this medication for weight loss instead of the intended purpose, which is to help control Type II diabetes.

Tirzepatide represents one of the most recent non-medical treatments aimed at managing the symptoms of Type II diabetes. While it is not indicated for weight management, diabetic patients who receive it frequently report a significant reduction in body weight.

 Empirical evidence suggests the efficacy of tirzepatide in weight management, and certain physicians currently endorse the Administration of the medication as a therapeutic and effective means to overcome obesity.

 

What are some severe side effects of tirzepatide that can impact patient safety?

The Administration of tirzepatide can benefit many individuals, but some severe side effects must be mentioned.

These include thyroid tumors, thyroid cancer, pancreatitis, hypoglycemia, serious allergic reactions, kidney issues, severe stomach problems, vision changes, and gallbladder issues. All these side effects must be taken seriously and reported, as they can lead to life-threatening

Conclusion

Medications like tirzepatide are game changers for those patients with type 2 diabetes that have failed other medications. Unfortunately, several companies seek to profit from its weight-loss benefits through aggressive marketing campaigns that limit the available supply and increase the costs for those who need it. As healthcare providers, we need to use sound clinical judgment and follow the exclusion/inclusion criteria and other guidelines before prescribing this medication, so we do not unintentionally cause harm while looking to appease our patients who request this.

Semaglutide and Type 2 Diabetes

Introduction   

In 2017, the FDA approved the semaglutide injectable (Ozempic) for treating type 2 diabetes. The drug has experienced widespread acceptance due to its positive effects on weight loss and lowering of chronic health risks. The drug has risen in popularity over the past few years, as many well-known actors/actresses/songwriters, and more came forward, publicly sharing their weight loss journey.

This rise in popularity has also resulted in significant shortages of this medication, negatively impacting the lives of the diabetic community, local pharmacies, and healthcare providers. The goal of this continuing education course is to educate and empower the healthcare provider in all aspects of this drug regimen: clinical indications, patient education, cost options, and benefit/risk analysis.

Diabetes Overview

Diabetes is a chronic medical condition. Despite advances in diet, medications, and monitoring devices, diabetes diagnoses continue to grow at staggering rates. The Institute for Health Metrics and Evaluation (IHME) reports that over 529 million people worldwide are currently living with diabetes, and that number is expected to grow to 1.3 billion in only 30 years. While the risk factors for diabetes are vast in number (poor diet, inadequate activity, obesity, sedentary lifestyles, daily stressors, and more), the sad reality is that this chronic medical condition will most likely linger on for generations to come despite our efforts to contain this health epidemic (1).

According to the latest research on diabetes, there are over 37 million people in the United States alone with diabetes as of 2022. Statistically, approximately 28 million of them have a confirmed diagnosis, while another estimated 8 million are experiencing symptoms, without an official diagnosis. Diabetes currently ranks as the 7th leading cause of death in the United States (2).

Types of Diabetes

In basic terms, diabetes is an impairment in one’s ability to either adequately produce or utilize insulin, which results in elevated levels of circulating glucose. Chronically elevated glucose levels affect blood vessels at every level, causing chronic inflammation and raising the risk of heart disease, stroke, blindness, and atraumatic amputations.

 

There are three main types of diabetes:

Type 1 diabetes is thought to be an autoimmune disease. Approximately 5-10 percent of people with diabetes are diagnosed with type 1 diabetes. The diagnosis usually occurs in early childhood, and results in a lifetime use of insulin to regulate blood glucose levels.

Type 2 diabetes is thought to be related to dietary and lifestyle choices. It accounts for nearly 90-95 percent of diabetes diagnoses. Usually occurring later in life (adult-elderly population), it is believed to be related to factors such as diet, activity, weight gain, and related factors. Type 2 diabetes is usually controlled by diet and exercise, in addition to oral medications, although injectable insulin may be included in the treatment plan.

Gestational diabetes refers to elevated glucose levels occurring during pregnancy for patients who are not diabetic at the onset of pregnancy. This version of diabetes usually resolves itself post-partum, although a woman may develop type 2 diabetes later in life, unrelated to pregnancy.

 

Type 2 diabetes in children: no longer a “later in life diagnosis”

Children are now being diagnosed with type 2 diabetes at an alarming rate. Despite widespread education and an increased awareness of diabetes, our up-and-coming generation is unhealthier than ever. Many families lack access to healthy food for their families, due to both general socioeconomic challenges and an increased rate of food insecurity. (19)

The CDC recommends care providers have resources for diabetic patients and their families, such as food and nutrition programsbudget-friendly diabetes meal plans, how to save money on diabetes care, and coping strategies for diabetes. (19)

Diabetes Signs and Symptoms, Diagnostic Testing

There are various ways to test for diabetes. The fasting blood sugar (FBS)/ fasting glucose level is a simple way to test for diabetes.

The normal fasting glucose level is below 100mg/dl. The fasting glucose result of 100-125mg/dl indicates prediabetes and results above 126mg/dl indicate diabetes.

The hemoglobin A1C blood test is another test used to confirm the diagnosis of diabetes. The patient does not need to be fasting for this test; thus, it is easier to order this test regardless of the time of day. This blood test reflects the average glucose level over the period of 2-3 months.

The normal A1C level is below 5.7%. Test results between 5.7%- 6.4% indicate prediabetes. Test results above 6.5% indicate diabetes.

A random glucose reading above 200mg/dl, done at any time of day, indicates diabetes.

The diagnosis of diabetes is by blood tests, and for improved accuracy, should be based on two separate readings, done (at least) a day apart. In the case of fasting and random blood tests, dietary intake (large amounts of carbohydrates in a single meal) may adversely affect test results. This is not the case when using A1C testing for a confirmation diagnosis, as the results are the average of a 2–3-month span.

 

Target blood levels for a person with diabetes (3).

Target blood glucose levels for people with diabetes are as follows:

  • Fasting glucose 80-130mg/dl.
  • Postprandial blood glucose level- less than 180mg/dl
  • A1C level 7-8%.

These target ranges are general guidelines. Patient-specific ranges will be dependent on a variety of factors, including preexisting comorbidities, overall health status, age, and activity levels.

 

 

 

 

The hallmark signs/symptoms of diabetes
  1. Polyuria- increased urination
  2. Polydipsia- increased thirst
  3. Polyphagia-increased hunger/appetite

 

The truth is, as healthcare providers, you will have patients who have no hallmark signs and symptoms of diabetes; the diagnosis will be found during annual preventive examinations often unrelated to any chronic disease. For this reason, many insurance companies now cover numerous preventive screenings, including diabetes screenings, as part of their wellness and prevention initiatives. These tests are often approved based on a patient's age, or preexisting conditions, rather than outright signs and symptoms.

Lifestyle Interventions and the Diabetes Prevention Program

The initial diagnosis of diabetes can be managed in a variety of ways, depending on the severity of the illness at the time of diagnosis. Lifestyle interventions (behavior modification education) are of utmost importance in the care and management of people with diabetes. Research over the past few decades has consistently shown that such interventions have immense positive effects on the successful long-term management of diabetes.

The official Diabetes Prevention Program was created in 2010 (4) and confirmed the effects of lifestyle interventions in the management of diabetes:  Lifestyle interventions decreased the incidence of type 2 diabetes by 58% compared with 31% in the metformin-treated group. Thus, these findings now serve as the blueprint, if you will, for all-inclusive, patient-specific disease management guidelines. These lifestyle interventions will be discussed in detail later in the program.

Semaglutide

Semaglutide is an injectable drug used in the treatment of type 2 diabetes. It was approved by the FDA in May of 2017.

It is a once-a-week injectable and belongs to the drug class known as glucagon-like peptide-1 receptor agonists (GLP-1RAs) (5). It has been referred to as a “miracle weight loss drug” among those who are living with obesity, despite frequent side effects, unusually high out-of-pocket costs, drug shortages, and weight regain when attempting to stop using the medication.

 

GLP-1 receptor agonist: Hormone Review

GLP-1 RAs are a class of medications used to treat Type 2 diabetes, and in some cases, obesity treatment. They are also known as GLP-1 receptor agonists, incretin mimetics, and GLP-1 analogs.

 

Ghrelin and Leptin (6)

Ghrelin and Leptin are two hormones that greatly influence appetite and the sensation of fullness. Often referred to as the “hunger hormone.” Ghrelin is responsible for many functions, including playing a key role in metabolism through glucose and insulin regulation.

Ghrelin, produced in your stomach, signals your brain when you are hungry, and results in increased food intake.

Leptin, conversely, is produced in your fat cells, and signals to the brain when you have eaten enough (by a decrease in appetite).

 

Glucagon-like peptide-1 receptors

Known as GLP1 receptors, Glucagon-like peptide-1 receptor proteins are located in the beta cells of the pancreas as well as in the neurons in the brain. GLP-1 receptors are involved in the regulation of blood glucose levels and affect the secretion of insulin. These cells encourage the release of insulin from the pancreas, increase the volume of beta cells, and reduce the release of glucagon. In doing so, they increase the feeling of fullness during and between meals, suppressing the appetite and slowing gastric emptying.

Ask yourself...

  1. What are some problems patients might face if they choose to take semaglutide?
  2. How do Ghrelin and Leptin relate to a patient's appetite?

What is meant by receptor agonist and antagonist?

The term agonist refers to any substance that mimics the actions of a hormone in producing a specific response: a receptor antagonist blocks a response from occurring.

Opioids are examples of receptor agonists in that they produce responses such as analgesia.

Naloxone/Narcan is an example of a receptor antagonist, in that it binds to a receptor site and decreases/blocks a response from occurring.

 

Semaglutide mechanism of action (7)

GLP-1 agonists work in several ways to positively affect glucose levels. Their mechanism of action includes the following:

  • Increasing (stimulating) insulin secretion by the pancreatic beta cells.
  • Decreasing the production of glucagon, a hormone that raises blood glucose levels
  • Decreasing (slowing) gastric emptying
  • Decreasing appetite (and thereby reducing food intake) by creating a sensation of stomach fullness

 

Through these mechanisms of action, semaglutide results in a lowering of serum glucose/A1C levels, which lowers the risk of cardiovascular events. Studies have also shown that semaglutide resulted in weight loss (approximately 8-14 pounds on average {dose dependent results}.

Side Effects of Semaglutide

Common side effects of semaglutide (8)

Common side effects may include any of the following:

  • Nausea and vomiting
  • Headache
  • Diarrhea and stomach pain
  • Upset stomach, indigestion, constipation, flatulence

These side effects usually subside within a few weeks, as the patient becomes acclimated to the medication.

 

Serious side effects of semaglutide
  • Hypoglycemia- enhanced/worsened when used in combination with other diabetes medication. Symptoms may include drowsiness, confusion, weakness, irritability, and headache.
  • Symptoms may include abdominal pain and distension, nausea and vomiting, fever, and back pain.
  • Diabetic retinopathy. Symptoms may include blurred vision, vision loss, and diminished night vision.
  • Kidney damage/injury/failure. Symptoms may include fatigue, nausea, diminished urine output, confusion, and edema of extremities.
  • Gallbladder disease. Symptoms may include gallstones, abdominal pain, nausea and vomiting, and poor appetite.

 

Black Box Warning (9)

Semaglutide has a Black Box Warning for thyroid cancer. This is the most serious warning from the Food and Drug Administration (FDA) and is intended to alert consumers to the potential risks of a medication.  This black box warning was issued when research found that the drug increased the risk of thyroid tumors in animals.

It is not known if semaglutide actually causes tumors in humans.

 

Contraindications
  • Semaglutide is contraindicated in people with a personal or family history of MTC (medullary thyroid cancer) or in patients with multiple endocrine neoplasia syndrome type 2.
  • Known hypersensitivity to semaglutide or any of the product components

 

Cautions

As noted under “serious side effects”, there have been reports of new illnesses or worsening of existing health conditions occurring “post-marketing”. Thus, healthcare providers are strongly encouraged to continue ongoing surveillance of any patients on semaglutide therapy. In addition, there is insufficient data available regarding the use of semaglutide by pregnant women. Women are therefore highly encouraged to stop any treatment with semaglutide for at least 2 months prior to a planned pregnancy.

Dosing

Semaglutide is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus (T2DM). It is looked upon favorably to reduce the risk of cardiovascular events in adults with T2DM and a preexisting history of cardiovascular disease. This drug is FDA-approved for use in people with diabetes, with a BMI of 27% or higher (a BMI of 25-29.9% is considered overweight).

Semaglutide (Ozempic) is available as an injectable prescription medication. Doses include 0.5mg, 1mg, or 2 mg, once weekly.

The injection should be administered subcutaneously to the abdomen, thigh, or upper arm. Injection sites should be rotated, and given as a single injection.

 

Start at 0.25 mg once weekly. After 4 weeks, increase the dose to 0.5 mg once weekly.

  • If additional glycemic control is needed, increase the dose to 1 mg once weekly after at least 4 weeks on the 0.5 mg dose.
  • If additional glycemic control is needed, increase the dose to 2 mg once weekly after at least 4 weeks on the 1 mg dose

Administer once weekly at any time of day, with or without meals.  The maximum dose recommendation is 2mg/weekly once weekly.

Note: The initial 0.25-mg dose is intended for treatment initiation and is not effective for glycemic control

 

 

Missing Dose Guidelines
  • If the missed dose is ≤5 days: Administer dose as soon as possible
  • If missed dose >5 days: Skip the missed dose and administer the next dose on the regularly scheduled day; patients can then resume their regular once-weekly dosing schedule

 

Administration Day Guidelines (10).

The administration day each week can be changed, if necessary, as long as the time between 2 doses is at least 2 days (>48 hours)

 

Dose Availability (packaging)
  • 2mg/1.5mL (1.34mg/mL); delivers doses of 0.25mg or 0.5mg per injection or four to eight doses per injection pen
  • 4mg/3mL (1.34mg/mL); delivers 1mg per injection or 4 doses per injection pen
  • 8mg/3mL (2.68 mg/mL); delivers 2mg per injection or 4 doses per injection pen

 

Treatment Goals- Effects on A1C and Weight (11)

A majority of adults who were placed on injectable semaglutide for diabetes management achieved a target A1C under 7% and were able to maintain it.

  • Dose specific effects on A1C were as follows:
  • 0.5mg dose injection yielded a 1.4% decrease
  • 1.0mg dose injection yielded a 1.6% decrease
  • 2.0 mg dose injection, in combination with diabetes pills, yielded a 2.1% decrease in A1C.

 

Adults taking semifluid injectables for diabetes management also noted weight loss.

  • 8-pound weight loss reported with 0.5mg dose injection
  • 10 pounds weight loss reported with 1.0mg dose injection
  • Up to 14 pounds of weight loss reported with a 2.0mg dose injection

Prescribing insights: Long-Term therapy for a chronic condition?

Semaglutide is viewed favorably as a treatment option for Type 2 diabetes. It appears to lower A1C levels and body weight in the majority of patients, lowering their risk of future cardiovascular events.

The question of long-term medication use, for a chronic health condition, is being heavily discussed in the media. While a percentage of people can decrease or eliminate the need for chronic medications through significant lifestyle changes, there have been reports of weight gain in those who stopped taking this injectable medication.

Without intense lifestyle behavior modification education, there is a heightened risk of weight regain in the absence of such medications. Leaders in the treatment of obesity and related illnesses have commented that this drug is intended for long-term use.

Examples of this include the following:

“GLP-1 medications [like Ozempic] are designed to be taken long-term... They are chronic medications for the treatment of chronic conditions (both diabetes and obesity) (12)". - Christopher McGowan, M.D., a gastroenterologist specializing in obesity medicine and endobariatrics

“As with many chronic conditions, most people who use the drugs for diabetes or weight loss will need to keep taking them to keep benefiting from them. Depending on your individual situation, and without sustained lifestyle changes, it is likely you would need to be on these medications indefinitely to maintain weight loss (13)." Dr. Cecilia Low Wang, a UCHealth expert in endocrinology, diabetes and metabolism.

Emerging Concerns: Semaglutide and gastroparesis

In August 2023, a first-of-its-kind lawsuit was filed in Louisiana, against the makers of semaglutide. The lawsuit states the makers of this injectable drug did not adequately warn patients about the risk of severe gastrointestinal issues/possible gastroparesis.

The plaintiff in this case had used both Ozempic and Mounjaro and experienced repeated episodes of severe gastrointestinal events, warranting trips to the emergency room and additional medications to alleviate her symptoms (14). While this lawsuit is in the developing stages, it bears mentioning in terms of concerns over long-term usage of the drug and possible complications.

While the drug labeling for semaglutide (Ozempic) does not specifically mention gastroparesis, the semaglutide/Mounjaro drug label does state that the drug has not been studied in patients with severe gastrointestinal disease and is therefore not recommended in these patients.

Up to 50% of people with diabetes have some degree of delayed gastric emptying, but most have no digestive symptoms or have only mild symptoms. For some people with diabetes, problems managing blood glucose levels may be a sign of delayed gastric emptying (15).

Healthcare providers should evaluate all patients with diabetes for possible symptoms of underlying gastroparesis, such as the feeling of fullness shortly after beginning a meal, or the inability to finish a regular meal. Other symptoms of gastroparesis may include abdominal pain, nausea, bloating, vomiting, and anorexia.

 

Diabetes and gastroparesis

Uncontrolled or poorly controlled diabetes can affect nerve endings systemwide. Diabetes is a very common cause of gastroparesis. Although the condition is rare it occurs more often in people with chronic conditions such as diabetes, autoimmune diseases, and nervous system disorders. Nerve endings are injured or damaged, cease to function properly, and result in delayed gastric emptying. The delay in gastric emptying can cause various symptoms, such as nausea, vomiting, bloating and distension, abdominal pain, and poor appetite.

In addition to underlying medical conditions, some medications may cause symptoms of gastroparesis (delays in gastric emptying and overall gastric motility. These medications include narcotics, antidepressants, and anticholinergics.

Left untreated, diabetic gastroparesis may lead to malnutrition, electrolyte imbalances, and poor glucose management and control.

Diabetes Lifestyle changes: Patient education (16)

  1. Weight Management
  2. Healthy Eating
  3. Physical Activity
  4. Smoking Cessation
  5. Stress Management

 

The importance of patient education regarding lifestyle changes is a priority. As with any chronic medication condition, the patient and their family/support system must be given every opportunity to educate and empower themselves on self-management of their disease process. Patients must be given the benefit of the doubt that they can indeed embrace their health and well-being and work with their healthcare provider in maximizing their health outcomes.

For diabetes mellitus, numerous lifestyle behaviors should be addressed and actively worked on, so that the patient receives the maximum health benefits. The following lifestyle behaviors are in no particular order; they all warrant discussion at every office visit.

 

Diet

A person with diabetes should be educated on the effects of food and nutrition on their glucose level. Referrals to a dietitian/nutritionist or Certified Diabetes Care Education Specialist (CDCES) should be considered a top priority. Well-balanced nutritional intake, appropriate carbohydrate awareness, calorie monitoring if weight loss is appropriate to your specific patient) and medication/food interactions are all essential aspects of dietary lifestyle education. Many commercial insurance plans, as well as hospital community outreach programs, offer diabetes self-management classes.

 

 

 

 

Activity (17)

The CDC recommends a target goal of 150 minutes weekly, Patients should be educated on the positive effects of daily activity on overall health and well-being, stress management, and metabolism. Patients should find activities they are genuinely interested in, involve family and friends, and slowly build greater endurance through increased intervals of longer duration.

 

Sleep hygiene (18)

Patients should be educated on the positive effects of a good night’s sleep. The aim should be approximately 7-8 hours of restful sleep. Electronics should be powered down and (optimally) removed from the bedroom. A dark, well-vented, cool room temperature is encouraged, and large meals and late-evening caffeine should be avoided.

 

Medication adherence/ literacy

Medication education is critical to the health and well-being of a patient. Routine education of the patient, and family members or support systems when available, should be supportive and patient-specific. Patients should be assessed on language barriers, literacy issues, and related comprehension concerns. Medication education should include effects, side effects, treatment goals, and sick day management. Emergency care issues should also be discussed. Any monitoring equipment (continuous glucose monitors, accuchecks, lancets) should be reviewed with patients and confirmed with return verbalization and demonstration.

 

As discussed in this course, patients with chronic diseases must learn self-management techniques to optimize their health and well-being. They must become confident in their understanding of their disease process and take ownership of their health. In doing so, they minimize the risk of long-term complications, improve their self-worth, and actively invest (both time and money) in their future.

Medication Assisted Treatment

Introduction   

Medication Assisted Treatment (MAT) is a treatment modality for substance use disorders. It combines counseling and behavioral therapies for addiction with medications used carefully to reduce the physical symptoms of cravings and withdrawal and assist clients in the recovery process. With half of people 12 and older reporting use of an illicit substance at least once and 21 million Americans experiencing addiction, this is an important and relevant topic (4).

Historically, an intense stigma is attached to both addiction and some of the medications used to treat addiction. A thorough understanding of substance use disorders, available MAT therapies, and care of affecting clients are essential topics for nurses to be familiar with, particularly those working in psychiatry, pain management, or addiction medicine.

Overview of Addiction and Substance Abuse:

Drug and alcohol abuse and addiction are chronic, complicated issues involving persistent changes to the brain. There is a stigma or misunderstanding that people with substance abuse disorders can stop any time they want to or lack the willpower or moral fortitude to stop using. This is entirely untrue, and even people who are "recovering" and have not had any drugs or alcohol in years can easily relapse into addiction once those brain changes have occurred (5).

When a person uses drugs or alcohol, the brain's reward center is flooded with dopamine. This provides a "buzz" or pleasurable sensation that may create the desire to use more of the same substance. Over time, and with regular use of the substance, the brain becomes accustomed to the flooding of dopamine and reduces the reward response, a process known as tolerance.

It will now take the same person a more significant amount of the substance to achieve the same "buzz" or "high" they used to feel. This process can also dull the pleasure response to activities not involving substance use, such as food, socialization, or sexual activity. Over time, the chemical changes in the brain can progress to include decreased functioning of learning, decision-making, judgment, response to stress, memory, and behavior (5).

To understand substance abuse disorders, it is first essential to understand some basic definitions. These terms are sometimes used interchangeably, but they mean different things and represent different stages of disease.

 

Definitions

Substance Use: Substance use is any consumption of drugs or alcohol, regardless of frequency or amount. An occasional glass of wine or taking an edible at a party is an example of substance use. Substance use does not cause problems or dependency in many people (5).

Substance Abuse: Substance abuse is the continued use of drugs or alcohol, even when they do cause problems. Conflict or problems at home, school, work, or legal issues related to the use of drugs or alcohol are signs of abuse. For example, being sent home from school for smoking in the bathroom or failing a drug test at work (5).

Substance Dependence or Addiction: Dependence and addiction can be used interchangeably or is sometimes called substance use disorder. Addiction occurs when a person cannot stop drinking or using drugs despite creating problems in their life. People who are addicted may experience cravings until they use a specific substance, or they may experience uncomfortable physical symptoms, known as withdrawal if they do stop (5).

The American Psychiatric Association (APA) utilizes the following criteria to diagnose clients who suffer from addiction. The more criteria a client answers yes to, the greater their problem with substance use.

Six or more positive criteria are indicative of addiction.

  1. Using substance in more significant amounts or for more extended periods than intended
  2. Trying to stop using but being unable to
  3. Increased amounts of time getting, using, or recovering from use of the substance
  4. Experiencing cravings or urges to use.
  5. Continuing to use the substance despite problems with relationships or social situations.
  6. Missing work, social, or recreational obligations or activities because of substance use
  7. Participating in risky behavior because of substance use
  8. Continuing to use the substance despite psychological or physical health problems.
  9. Needing to use more substance over time to achieve the desired effect.
  10. Experiencing withdrawal symptoms when stopping the substance (1).

Substance Abuse Statistics

Many factors go into gathering data on substance abuse disorders, from underreporting, the nuance between use, abuse, and addiction, and the large variety of substances available, with the legality of some substances varying by state or age.

The statistics below from 2020 are not meant to be an exhaustive list of substance use disorders in this country but rather an overview of some of the more prevalent addiction-related issues.

  • 50% of people 12 years and older have used an illicit substance at least once.
  • 5% of Americans 12 years and older have used drugs within the last month.
  • This is a 3.8% increase from the previous year.
  • About 50% of Americans 12 and over drink alcohol
  • 4% of those people have an alcohol use disorder.
  • About 20% of Americans use tobacco products or vape
  • 18% of Americans over 18 used marijuana in the last 12 months
  • 30% of those have some level of misuse or addiction.
  • Marijuana is commonly involved in polysubstance use, paired with alcohol or other drugs.
  • 7% of Americans over 12 misused opioids in the last 12 months
  • 96% of those used prescription pain relievers
  • Opioid prescriptions peaked in 2012, with 81.3 prescriptions per 100 people.
  • The rate has declined recently due to increased attention to this crisis.
  • In 2018, the rate was down to 51 prescriptions for every 100 people
  • Fentanyl is now rising as a new and deadly concern.
  • 5 million prescriptions were written for fentanyl in 2015.
  • Fentanyl is involved in 53% of overdose deaths.
  • 7% of all Americans misuse a prescription drug.
  • 1% of those misuse stimulants
  • 2% of those misuse sedatives
  • 5% misuse painkillers
  • Over 70,000 drug overdose deaths occur annually in the United States (4)

Risk Factors

A combination of factors is involved in the risk of addiction, and no one factor can determine if someone will develop addiction or after how many uses this will occur.

The addiction process does occur more easily or progresses more rapidly for people with certain risk factors, including:

 

Genetics

There is a strong genetic correlation with addiction, indicating that biology plays a significant role in the disorder. Family history of addiction, gender, ethnicity, and comorbid mental health conditions can all influence the risk of addiction. (5)

  • Children of addicts are eight times more likely to develop an addiction at some point.
  • In 2020, among those using illicit or misusing prescription drugs, 22% were male and 17% female.
  • Only 20% of users in drug treatment programs are women.
  • 9% of people with substance abuse disorders also have at least one mental health disorder (4)

 

Environment/Non-Genetic Demographics

The attitudes about drugs and alcohol from those in a person's network and life experiences play a role in the risk of addiction. Substance use among friends, family, or coworkers increases the risk that a person will also use substances. Exposure to substance use from a young age relaxed parental attitudes about substance use, and peer pressure from friends can increase the risk. Certain stressful life circumstances such as veteran status, history of sexual or physical assault, or being part of the LGBTQ community can also increase risk. (5)

  • 20% of people in urban areas used illegal drugs in 2020 compared to 5% in rural locations.
  • 51% of Americans with an illegal pain relief medication obtained it from a friend or relative.
  • 7% of LGBTQ Americans abuse illicit drugs.
  • 2% of LGBTQ Americans abuse alcohol.
  • 7% of Veterans abuse illicit drugs.
  • 80% of Veterans abuse alcohol (4)

 

Developmental Stage

Substance use at any age can lead to addiction, but children and teens are at particular risk due to their underdeveloped brains. The parts of the brain responsible for decision-making, risk assessment, and self-control do not fully develop until the early 20's, putting teenagers at increased risk of dangerous behaviors. In addition, the effects of drugs and alcohol on the developing brain may mean that those parts of the brain never fully develop at all for teens with substance abuse disorders. (5)

  • 70% of users who try an illegal substance before age 13 will develop a substance use disorder within the next seven years.
  • This is for only 27% of people who first try an illegal substance after age 17.
  • 47% of youths report trying an illegal substance by the time they graduate high school (4)

Overview of Medication Assisted Treatment (MAT)

Treatment of substance abuse disorders is a complex and often tumultuous process. The nature of the brain changes that occur during addiction means that a person is never entirely "cured" but will always be considered "recovering" as the risk for relapse is always present. Effective treatment must be multifaceted and often involves removing triggers (such as people, places, and stressors) that may prompt a person to use again behavioral therapy, and medications to curb withdrawal symptoms and reduce cravings.

Medication Assisted Treatment (MAT) is a treatment that involves FDA-approved medications, in combination with behavioral therapy, in the recovery process for substance abuse disorders. Several medications are available for MAT, and evidence continues to emerge that the treatment is highly effective if used correctly.

However, it is a vastly underused and understudied treatment modality. MAT has been available in some form for over 50 years but is just starting to gain traction among the medical community (and policymakers) in recent years, with the federal government calling for more research and increased accessibility for the treatment (8).

The height of the opioid crisis in the last several years has highlighted the magnitude of drug addiction and deaths in the United States, bringing renewed attention to MAT as a treatment option. So, how does MAT work? Prescription medication is given to both stimulate the receptors seeking the abused substance and block the drug's euphoric effects.

Over time, this normalizes brain chemistry and helps the person break the habit of using without the discomfort of cravings and withdrawal symptoms. Gradually, the prescription medication dosage is reduced, all the while in conjunction with behavioral therapy and lifestyle changes, and eventually, the client should be able to stop the medication altogether, often within 1-3 months (8).

MAT does require close supervision by a trained medical professional and an appropriate facility for treatment. It can be done on an inpatient, partial inpatient, or outpatient basis. There may be side effects to the medication, and there is a risk of misusing or developing addiction to the new drug, though the successful outcomes often outweigh this risk. Clients must also participate in behavioral therapy for a comprehensive and effective treatment plan. As with any treatment regimen, careful consideration of the client's history and circumstances is essential (8).

Pharmacokinetics

Currently, there are three medications with FDA approval for MAT: buprenorphine, methadone, and naltrexone. Each will be discussed in depth below.

 

Buprenorphine
Mechanism of Action and Metabolism

Buprenorphine is an opioid partial agonist, acting on the same receptors as other opioids but with weaker effects. It can be used for the treatment of misuse of opioids, including:

  • Heroin
  • Fentanyl
  • Oxycodone
  • Hydrocodone
  • Morphine
  • Methadone (3)

 

Opiate receptors are G-protein coupled receptors (GPCRs) with four major types: Mu, Delta, Kappa, and opioid receptor like-1 (ORL1). Stimulation of these receptors results in varying levels of the following effects:

  • Euphoria
  • Relaxation
  • Pain relief
  • Sleepiness
  • Sweating
  • Constipation
  • Impaired concentration
  • Reduced sex drive (3)

 

Buprenorphine has a high affinity to the Mu-opioid receptor and is a partial agonist at this site, causing reduced opioid effects with a plateau or ceiling at higher doses. This limits dangerous effects and makes overdose unlikely. It also has slow dissociation from the site, allowing milder and more easily tolerated withdrawal effects compared to full agonists like morphine and fentanyl. Buprenorphine is also a weak kappa receptor antagonist and delta receptor agonist, reducing the craving sensation and improving tolerance to stress (3).

Buprenorphine has poor bioavailability when given orally due to the first-pass effect, where most of the drug is broken down in the liver and intestines. Because of this, sublingual or buccal are the preferred routes of administration and the most common forms in which the drug is manufactured. Transdermal patches and IV and IM forms exist, though not for use in MAT (3).

CYP34A enzymes break down buprenorphine, so other drugs, such as ketoconazole, may inhibit metabolism and increase available levels of buprenorphine. CYP34A inducers such as carbamazepine, topiramate, phenytoin, and barbiturates may speed metabolism and lower available levels. Once broken down, the med takes the form of norbuprenorphine and is excreted in the feces (3).

 

Available Forms

Buprenorphine is available by itself and with naloxone (in a 4 to 1 ratio). However, in oral form, naloxone is not readily absorbed, and buprenorphine is the only genuinely active ingredient. This combination is beneficial should clients try to inject their buprenorphine to get high; naloxone is a fast-acting opioid antagonist that is active when used intravenously and would block the opioid effect of buprenorphine, rendering it useless for recreational use and ensuring it has no street value.

The currently available preparations of buprenorphine for MAT include:

  • Generic Buprenorphine/naloxone sublingual tablets
  • Subutex - Buprenorphine sublingual tablets
  • Suboxone - Buprenorphine/naloxone sublingual films
  • Zubsolv - Buprenorphine/naloxone sublingual tablets
  • Bunavail - Buprenorphine/naloxone buccal film (3)

 

Sublingual products dissolve within 2-10 minutes. Bloodstream absorption begins quickly, bypassing the first pass effect. Buprenorphine has a slow onset of action, peaking about 3-4 hours later. Metabolism is also slow, with the half-life lasting anywhere from 25 to 70 hours (an average of about 38 hours). This long half-life means the drug can be spaced out to every other day administration once weaning begins (3).

 

Dosing and Monitoring

Clients prescribed buprenorphine must stop using opioids for at least 12 to 24 hours before the first dose; this varies depending on which opioid they are stopping. For short-acting opioids like heroin and oxycodone, buprenorphine may be started 6-12 hours after the last dose. With longer-acting opioids such as morphine or extended-release preparations of oxycodone, buprenorphine should be delayed for about 24 hours. For the longest action opioids, fentanyl patch, 48 -72 hours must be between the last dose and buprenorphine initiation (3).

This initiation schedule means clients will be in the early stages of discomfort and withdrawal. Administration of buprenorphine when clients still have opioids in their bloodstream will lead to competition for receptor sites, rapidly replacing the opioid with buprenorphine and causing acute and more severe withdrawal symptoms.

Depending on the severity of a client's addiction, they may complete the first step of abstaining and withdrawal in an inpatient setting. Once the initial withdrawal symptoms have passed and the initial dose of buprenorphine has been given, the client may be discharged home to continue buprenorphine initiation on an outpatient basis (3).

Initial doses are typically 2-4mg, with up to 4mg given to clients used to higher potency or larger doses of opioids. The dose is gradually increased to meet the client's individual needs, with a maximum dosage of 24mg per day. The average client requires 8-12 mg per day and can reach this dose within the first 2-4 days. It is recommended that doses be supervised by a pharmacist at the dispensing pharmacy for the first two months of treatment to ensure compliance and clients are less likely to relapse (3).

The length of treatment with buprenorphine depends on each client's case and, for some, may be indefinite. Clients who do wish to wean off buprenorphine can begin the process once they are stable and experiencing few or no cravings, and a minimum of 8 weeks from treatment initiation. Doses are moved to alternating days and eventually discontinued altogether (3).

 

Side Effects and Contraindications:

As with any medication, there are potential side effects, including:

Common Side Effects

  • Nausea
  • Vomiting
  • Drowsiness
  • Dizziness
  • Headache
  • Memory loss
  • Sweating
  • Dry mouth
  • Miosis
  • Postural hypotension
  • Sexual dysfunction
  • Urinary retention

 

Serious side effects

  • CNS depression
  • QT prolongation
  • Reduced seizure threshold
  • Potential for abuse or overdose (3)

 

Buprenorphine is contraindicated for clients with a past hypersensitive reaction to it. It should be used cautiously for clients with respiratory suppression, older adults, or for those with liver pathologies. Regular monitoring of liver enzymes via lab work is essential (3).

It is a Category C medication for pregnancy, and the risks versus benefits should be carefully weighed. Buprenorphine does cross the placenta and increases the risk of withdrawal symptoms and neonatal abstinence syndrome (NAS) after delivery. However, for pregnant clients with the highest risk of relapse and abuse of opioids, evidence does support that continuation of buprenorphine during pregnancy may improve maternal and fetal outcomes (3).

Buprenorphine may be abused by crushing tablets, snorting the powder, or dissolving it into an injectable solution. Safety measures against this include supervised administration by a pharmacist and the addition of naloxone, which blocks the buprenorphine effects. While the effect ceiling of buprenorphine makes overdose difficult, combining the drug with benzodiazepines, alcohol, or other drugs can compound the CNS depressant effects and increase the risk of overdose (3).

Clinicians need to have a comprehensive health history of clients before initiating buprenorphine so that all risks and potential interactions can be addressed appropriately.

 

Role of the Pharmacist

Pharmacists play a significant role in the success of MAT involving buprenorphine. Outpatient doses are monitored by the dispensing pharmacist daily, with at-home quantities being allowed on a limited basis (such as weekends or travel) and only for the most motivated and compliant clients. Vital signs are collected before each dosage, with careful monitoring for hypotension or bradypnea. The dose may be skipped for clients who experience excessive side effects, and the client can return the next day for their dose.

Clients presenting with signs of overdose (usually to the ED) may receive naloxone, which will reverse overdose symptoms within 1 hour. Overdose symptoms include dizziness, pinpoint pupils, hypotension, bradypnea, hallucinations, seizure, or unconscious state.

If a client misses a dose, does not show up for it, or is experiencing significant side effects from buprenorphine, the prescribing clinician should be notified so that the treatment plan can be revisited and revised if needed (3).

 

Considerations for the Prescriber

When considering which medication to prescribe for MAT, prescribers should understand that buprenorphine offers advantages over methadone.

  • Lower risk of abuse
  • Safer, including at higher doses.
  • Therapeutic dose achieved quickly.
  • Easier to taper.
  • Can be obtained from any provider rather than a methadone clinic.
  • Less stigma

 

The cost of a 30-day supply is around $300. Buprenorphine/naloxone combinations are a little more expensive at $400/month. While prior authorization is usually required, most commercial insurance and state Medicaid programs will cover the medication.

Buprenorphine is a Schedule III Controlled Substance; however, recent federal regulations have been aimed at approving access to MAT, and any provider with an active DEA license may prescribe buprenorphine as allowed by state regulations. Specialized clinics are not required (as they are with methadone), and it is dispensed at regular pharmacies.

Prescribers are encouraged to participate in additional training about MAT with buprenorphine, but it is not required. Detailed documentation must be completed, including the reason for prescribing, start and end dates of treatment, the pharmacy used, the credentials of who will supervise administration, and frequency of follow-up and compliance monitoring. The sublingual and buccal routes are the only forms of medication used for MAT; patches, IM, and IV preparations are not routinely used for MAT.

The success of buprenorphine treatment depends on the client's education. Addiction potential, risk of combination with other CNS depressants, and side effects vs. signs of overdose should all be discussed with clients and their support system (3).

Methadone
Mechanism of Action and Metabolism

Methadone is a synthetic opioid and a full agonist of the Mu-receptor site, stimulating the same effects as opioids.

  • Euphoria
  • Analgesia
  • Sedation

 

It can be used as a potent analgesic for pain not responding to traditional medications, such as in clients with cancer or terminal illness, as well as for MAT and neonatal abstinence syndrome (NAS).

For this course, it will be discussed as a MAT agent, used in treatment for clients addicted to opioids such as:

  • Heroin
  • Fentanyl
  • Oxycodone
  • Hydrocodone
  • Morphine
  • Hydromorphone (2)

 

Methadone is a full agonist at the Mu-receptor, meaning it is a more potent and more easily addictive medication than partial agonists like buprenorphine. Methadone has a long half-life (8-60 hours), occupying the Mu-receptors and blocking short-acting opioids from making a client high. The longer half-life also leads to less severe cravings and withdrawal symptoms. Methadone is also an antagonist to the N-methyl-d-aspartate (NMDA) receptor, which adds to its pain relief action (2).

It has high oral bioavailability, is active in the bloodstream within 30 minutes of ingestion and remains elevated for around 24 hours. It is broken down via CYP3A4 and CYP2B6 enzymes and metabolized through the liver, making it a good option for clients with renal problems.

Medications such as ciprofloxacin, benzodiazepines, fluconazole, cimetidine, and fluoxetine may slow methadone metabolism, increasing the available drug and the side effects of overdose risk. Other medications may speed metabolism and decrease the effects of methadone, including phenobarbital, phenytoin, rifampin, ritonavir, and carbamazepine (2).

 

Available Forms

Methadone is available in many forms, including oral, IM, subcutaneous, IV, and intrathecal, though only the oral is typically used for MAT.

  • Methadone - tablets
  • DISKETS - dispersible/dissolvable tablet
  • Methadone HCL Intensol - 10mg/ml suspension
  • Methadone - dispersible tablet (2)

 

Dosing and Monitoring

Oral dosing is initiated at 30-40 mg/day with a slow titration of 10-20 mg/week until the optimal dosage is reached. The optimal dosage varies by client and depends on the drug they are replacing, tolerance to opioids, and side effects experienced. A dosage between 80- 150 mg/day is the typical goal. (2)

If parenteral methadone is given, it is usually 50%-80% of the oral dosage.

Blood sugar, EKG, and methadone blood levels should be checked regularly, every week for higher-risk patients, and every 3-6 months for those in good health and compliance. The target methadone blood level is around 400 ug/ml (2).

 

Side Effects and Contraindications

Potential side effects are directly related to stimulation of the opioid receptors and include:

  • Diaphoresis
  • Flushing
  • Pruritus
  • Nausea
  • Dry mouth
  • Constipation
  • Sedation
  • Lethargy
  • Respiratory Depression
  • QT prolongation
  • Hypoglycemia (2)

 

Methadone should be considered with a comprehensive view of a client's health history and other medications. Clients with CNS-related disease processes (trauma, increased ICP, dementia, or delirium) must be monitored closely or have other medication considered.

Methadone should not be used simultaneously as other opioids, benzodiazepines, alcohol, or antipsychotics due to increased CNS effects. Methadone is a Pregnancy Category C medication, and risks versus benefits should be weighed carefully. Infants exposed to methadone in utero are at increased risk of NAS after delivery (2).

Overdose can occur, and clients and support systems should be educated on signs of overdose.

  • Lethargy
  • Somnolence
  • Stupor
  • Coma
  • Miosis
  • Bradycardia
  • Hypotension
  • Respiratory sedation
  • Cardiac arrest

 

Naloxone is used to reverse overdose (2).

 

Considerations for Prescribers and Clinics

Methadone is a Schedule II Controlled Substance, meaning it has a high abuse potential and must be carefully monitored. The Prescription Drug Monitoring Program (PDMP) is an electronic database used nationwide to register the distribution of controlled substances so that clients do not seek care at multiple clinics or pharmacies to obtain more of a controlled substance.

When prescribing methadone, providers should check the PDMP for both methadone and other prescription opioids so that they are fully aware of other medications clients may be receiving from other places. Regular urine drug screening should be performed to make sure clients are not using other substances not obtained by prescription and that they are testing positive for methadone, meaning they are genuinely taking it if administration is not observed (2).

At the beginning of treatment, methadone is given in the office under a nurse's supervision, and then clients are monitored for adverse effects. Some take-home doses (up to 7 in the first two weeks) may be arranged for weekends or during travel, but this possibility is limited during the first few weeks of treatment. As treatment progresses and compliance is demonstrated, clients may self-administer more doses at home (up to 28 doses per month) and go longer between visits to the clinic. The total length of treatment varies but is often 1-2 years and can even be indefinite (7).

There are methadone clinics that work entirely in the scope of addiction management, but primary care providers may prescribe methadone as well. Prescribers must have an active DEA license and comply with state-based controlled substance regulations (2).

Naltrexone
Mechanism of Action and Metabolism

Naltrexone has been in use since the 1960s and is an opioid antagonist. It competes primarily with the mu-receptor but also serves as an antagonist at the kappa and delta receptors. As an antagonist, it competes with agonists such as opioids and alcohol and blocks the effects of agonists at those sites.

  • Prevents euphoria.
  • Prevents intoxication.
  • Reduces tolerance (6)

 

Naltrexone also acts on the hypothalamic-pituitary-adrenal axis, modifying it to reduce cravings and suppress alcohol consumption.

It is FDA-approved for use in clinical practice for the treatment of:

  • Alcohol use disorder
  • Opioid use disorder (prescription and non)

 

Naltrexone is absorbed orally and undergoes extensive metabolism via the first-pass effect. However, this does not affect its potency as naltrexone's active metabolite, 6β-naltrexone, acts as a potent opioid antagonist. The medication's half-life is around 4 hours but can last up to 24 hours. If administered parenterally, it bypasses the first pass and is even longer acting, with a half-life of 5-10 days. Naltrexone is excreted by the kidneys (6).

 

Available Forms

Naltrexone is available in an oral tablet and IM injection. Available preparations include:

  • Generic naltrexone tablets
  • Revia (oral tablet)
  • Depade (oral tablet)
  • Vivitrol (solution for IM injection, extended-release) (6)

 

Dosing and Monitoring

Since naltrexone will compete for and block all opioid receptor sites, the risk for withdrawal symptoms is high, and clients must stop the use of alcohol or opioids for 7-10 days before beginning treatment to lessen the risk of withdrawal symptoms. A naltrexone challenge is recommended at the start of therapy.

This consists of administering small amounts of naltrexone subcutaneously or via IV and monitoring the client and their vital signs for signs of withdrawal, such as:

  • Nausea
  • Vomiting
  • Diaphoresis
  • BP changes
  • Tachycardia
  • Rhinorrhea
  • Agitation
  • Tremors
  • Abdominal pain
  • Pupillary dilation (6)

 

If a client fails the naltrexone challenge and has not been long enough since their last use of alcohol or opioids, the naltrexone initiation should be delayed, and the test should be repeated in 24 hours. If clients tolerate the naltrexone test and the negative result, they may begin naltrexone treatment (6).

For oral tablets, dosing usually starts at 25 mg for the first dose. Clients are observed for withdrawal symptoms and side effects; an additional 25 mg is given 1 hour later. After that, clients take 50 mg per day. Clients may continue with 50mg daily or take 100 mg every other day or 150 mg every 3rd day (6).

Alternatively, naltrexone may be given via IM injection for more extended action, improving compliance and reducing relapse. Particularly for alcohol or heroin dependence, data indicates that the IM route has much higher success rates than the oral route. If a client receives the IM injection, 380 mg is given to the gluteal muscle every four weeks (6).

 

Side Effects and Contraindications

Most common side effects of naltrexone include:

  • GI irritation
  • Diarrhea
  • Abdominal cramps
  • Nausea
  • Vomiting
  • Hypertension
  • Headache
  • Anxiety
  • Low energy
  • Joint or muscle pain
  • Nervousness
  • Sleep disruption

 

Less commonly, clients report:

  • Loss of appetite
  • Constipation
  • Dizziness
  • Irritability
  • Depression
  • Rash
  • Chills (6)

 

Caution should be used for clients with liver function issues and renal impairment. It is Category C for use during pregnancy, and the risks versus benefits of use in pregnancy must be carefully considered. It also crosses into breast milk and must be considered carefully.

There is limited data about the overdose of naltrexone, and there may be very few symptoms if an overdose occurs. Clients should be monitored for signs of liver dysfunction, seizures, depression, and suicidal ideations. No antidote for naltrexone is currently available.

Naltrexone is contraindicated for clients who failed a naltrexone challenge, test positive for opioids or alcohol on drug screening, have a history of seizures, or have experienced a past hypersensitivity reaction to naltrexone.

Clients may switch from buprenorphine or methadone to naltrexone at some point in treatment. Both medications are agonists at the opioid receptor sites, so changing to naltrexone (an antagonist) may increase the risk of withdrawal symptoms for the first two weeks of treatment (6).

 

Considerations for Prescribers

Because naltrexone does not cause any euphoria or "high," the abuse potential is non-existent. It is not a controlled substance and can be prescribed by any clinician with prescriptive authority. However, its use is typically only by those who work in mental health or addiction medicine. Clients can take the medication at home or go to the clinic for IM injections.

Many considerations for naltrexone use center around monitoring for side effects and treatment compliance. Baseline and periodic drug screening and liver function tests are prudent. Clients' support persons should be educated on compliance and signs of relapse. The IM formulation should be considered for those with poor compliance or most at risk for relapse (6).

  4. What does it mean if a client fails a "naltrexone challenge," and how does this delay their care?

Nursing Considerations

Nurses will encounter clients with addiction and even those receiving MAT in a variety of settings, including:

  • Outpatient clinics for routine care of any health issues
  • ED admission for acute problems not related to addiction.
  • Inpatient hospitalization related to other health problems.
  • Outpatient setting for participation in MAT or addiction management.
  • ED admission for acute problems related to substance abuse or toxicity of MAT medication.
  • Inpatient mental health admission for mental health and addiction issues

 

Regardless of the setting and if the client is being seen for an addiction issue or something else, it is crucial for nurses to be familiar with MAT medications and how they work to provide safe and competent care. Nurses may need to:

  • Administer medication.
  • Monitor lab results.
  • Observe for side effects, toxicity, or withdrawal symptoms.
  • Coordinate care within a multidisciplinary team
  • Communicate with therapeutic and nonjudgmental techniques.

Justin is a 32-year-old male who presents to the ED with nausea, lethargy, and confusion worsening over the last 24 hours. Upon exam, the nurse notes diaphoresis, slurred speech, and pinpoint pupils. His vitals are RR 10, HR 54, BP 82/58, SPO2 97%, Temp 99.0.

He reports taking Wellbutrin 150mg daily for depression and smoking cessation, methadone 100mg daily for history of oxycodone abuse, and was started on ciprofloxacin 250mg BID for a UTI 2 days ago at urgent care.

His labs are significant for a WBC of 15,000 but otherwise regular. He tests positive for methadone, which is expected, but not for other substances. He reports being compliant with MAT and avoiding opioid use for nine months.

It is determined that Justin is experiencing methadone toxicity due to the slowed metabolism of the drug from the combination of methadone and ciprofloxacin. He is given naloxone in the ED, and within an hour, his symptoms have improved significantly, and his vital signs are typical. His antibiotic is switched to cefdinir, and he is discharged home in stable condition with instructions to follow up with his PCP within 1-2 days.

Conclusion

Substance use disorders are a long-standing and dangerous pathology experienced by millions of people each year. At the same time, the stigma of seeking help for such disorders has been eroding in recent years; there has also been a renewed push by the federal government to address the issue in evidence-based and meaningful ways, with access to effective treatment being at the top of the priority list.

Addiction treatment programs utilizing MAT will likely become much more popular in the coming years, and nurses will be on the front lines of this therapy. For nurses to provide competent and comprehensive care to this client population, up-to-date and accurate knowledge is necessary.

Hypertensive Agents

 

Definitions 

 

Hypertension – high blood pressure above normal. Normal is considered anything less than 120/80 mmHg [7]. 

Antihypertensives – medications used to control hypertension and lower blood pressure [7]. 

Hypertensive crisis – severely elevated blood pressure of either: 

  1. Systolic greater than 180 mmHg 
  1. Diastolic greater than 120 mmHg [19]. 

Hypertensive emergency – acutely elevated blood pressure with signs of target organ damage [2].

Medications Overview 

Antihypertensive medications are used for the treatment of hypertension and are used in both inpatient, outpatient, and emergency settings.  

Some of the major antihypertensive medication classes include: 

  • Diuretics 
  • Beta-blockers 
  • Angiotensin-converting enzyme inhibitors 
  • Angiotensin II receptor blockers 
  • Calcium channel blockers 
  • Selective alpha-1 blockers 
  • Alpha-2 Receptor Agonists 
  • Vasodilators [3]. 

Different medical organizations have varying recommendations and hypertension treatment guidelines. Hypertension treatment clinical practice guidelines are available from organizations like the American Heart Association, the American College of Cardiology, and the European Society of Cardiology to name a few [21]. Healthcare providers should be aware of their healthcare institution’s recommendations for clinical practice guidelines and organizations.  

All organizational guidelines share the same recommended treatment of starting antihypertensives immediately when: 

  1. Blood pressure is greater than 140/90 mmHg for patients with a history of ischemic heart disease, heart failure, or cerebrovascular disease. 
  2. Blood pressure is greater than 160/100 mmHg regardless of underlying medical conditions [21]. 

Again, healthcare providers should follow current and evidence-based clinical guidelines for initiating or titrating antihypertensive medications. 

While most antihypertensives are prescribed in an outpatient setting, certain antihypertensives are indicated during hypertensive or medical emergencies. For example, intravenous (IV) vasodilators, like nitroprusside and nitroglycerin, and calcium channel blockers, like nicardipine, are used during hypertensive emergencies and crises.

Pharmacokinetics 

Diuretics 

Diuretics are a class of drugs that help control blood pressure by removing excess sodium and water from the body through the kidneys. There are several varying types of diuretics, some including thiazide, potassium-sparing, and loop, and all work to lower blood pressure differently [3]. 

 

Thiazide Diuretics 

Thiazide diuretics remove excess sodium and water from the body by blocking the sodium-chloride (Na-Cl) channels in the kidneys’ distal convoluted tubule. As the Na-Cl channel becomes blocked, this inhibits the reabsorption of sodium and water into the kidneys. Concurrently, this causes a loss of potassium and calcium ions through the sodium-calcium channels and sodium-potassium pump [1]. 

Thiazide diuretics are approved by the Food and Drug Administration (FDA) for controlling primary hypertension and are available via oral route. Some common thiazide diuretics are hydrochlorothiazide, chlorthalidone, and metolazone [3].  

When initiating this medication, the healthcare provider should start with the lowest dose, which is usually 25mg daily, and then increase accordingly to aid with blood pressure control or if the patient has excess fluid retention, usually as evidenced by leg swelling or edema [1].  

 

Common side effects of thiazide diuretics include: 

  • Increased urination 
  • Diarrhea 
  • Headache 
  • Stomach and muscle aches [16]. 

 

As thiazide diuretics interfere with Na-Cl, Na-Ca, and Na-K channels, there is an increased potential for adverse effects, including: 

  • Hypotension 
  • Hypokalemia 
  • Hyponatremia 
  • Hypercalcemia 
  • Hyperglycemia 
  • Hyperlipidemia 
  • Hyperuricemia 
  • Acute pancreatitis 

 

When prescribing thiazide diuretics, healthcare providers should avoid prescribing thiazide diuretics to patients with a sulfonamide allergy, since thiazides are sulfa-containing medications. Also, they should avoid prescribing these to patients with a history of gout [1].  

Additionally, patients can experience a thiazide overdose if they take more than the amount prescribed. Patients with a suspected overdose may experience confusion, dizziness, hypotension, and other symptoms. These patients must seek emergency care and poison control must be alerted [16]. 

 

Potassium-Sparing Diuretics 

Potassium-sparing diuretics remove excess sodium and water from the body without causing loss of potassium. Depending on the type, they interrupt sodium reabsorption by either binding to epithelial sodium channels or inhibiting aldosterone receptors. When catatonic sodium is reabsorbed, this creates a negative gradient causing the reabsorption of potassium ions through the mineralocorticoid receptor [5]. 

Potassium-sparing diuretics are approved for controlling hypertension and are usually combined with other diuretics, like thiazide or loop diuretics since they have a weak antihypertensive effect.  

Common names of potassium-sparing diuretics are amiloride, triamterene, and spironolactone. These medications are available by either intravenous or oral routes. Spironolactone is commonly used for treating primary aldosteronism and heart failure [5]. Patients should be started on the lowest dose when first prescribing this class of medications.  

 

Common side effects can include: 

  • Increased urination 
  • Hyperkalemia 
  • Metabolic acidosis 
  • Nausea  

[4] 

Healthcare providers should avoid prescribing this class of medications to patients with hyperkalemia or chronic kidney disease. They should also be avoided during pregnancy or in patients who are taking digoxin. Since potassium-sparing medications can cause hyperkalemia, periodic monitoring for electrolyte imbalances and potassium levels is necessary [4]. 

 

Loop Diuretics 

Loop diuretics inhibit sodium and chloride reabsorption by competing with chloride binding in the Na-K-2Cl (NKCC2) cotransporter. Potassium is not reabsorbed by the kidney, which causes additional calcium and magnesium ion loss.  

Loop diuretics are FDA-approved for the treatment of hypertension but are not considered first-line treatment. They can also be used for treating fluid overload in conditions like heart failure or nephrotic syndrome [12]. 

Loop diuretics are available via oral or IV routes and furosemide, torsemide, and bumetanide are common forms [3].  

Bioavailability and dosage differ for each type and route of loop diuretics. The bioavailability of furosemide is 50%, with a half-life of around 2 hours for patients with normal kidney function, and dosages start at 8mg for oral medication. Torsemide has a bioavailability of about 80%, a half-life of about 3 to 4 hours, and oral dosages start at 5mg [12].  

 

Common side effects can include: 

  • Dizziness 
  • Increased urination 
  • Headache 
  • Stomach upset 
  • Hyponatremia 
  • Hypokalemia [13]. 

 

Loop diuretics can lead to several adverse effects, including toxicity, electrolyte imbalances, hyperglycemia, and ototoxicity. They have a black box warning stating that high dosages can cause severe diuresis. Therefore, electrolytes, BUN, and creatinine values should be monitored closely by a healthcare provider.  

People with a sulfonamide allergy may also be allergic to loop diuretics, so this should be avoided if the patient is allergic. Loop diuretics also interfere with digoxin and therefore should be avoided. Other contraindications include anuria, hepatic impairments, and use during severe electrolyte disturbances [12].

Beta-Blockers 

Beta-blockers work by reducing the body’s heart rate and thus, lowering cardiac output resulting in lowered blood pressure [3]. The mechanism of action for beta-blockers varies, depending on the receptor type it blocks, and are classified as either non-selective or beta-1 (B1) selective.  

Non-selective beta-blockers bind to the B1 and B2 receptors, blocking epinephrine and norepinephrine, causing a slowed heart rate. Propranolol, labetalol, and carvedilol are common non-selective beta-blockers.  

Alternatively, beta-1 selective blockers only bind to the B1 receptors of the heart, so they are considered cardio-selective. Some examples include atenolol, metoprolol, and bisoprolol. Sotalol is a type of beta-blocker that also blocks potassium channels and is, therefore, a class III antiarrhythmic [8]. 

Beta-blockers are not primarily used for the initial treatment of hypertension but can be prescribed for conditions like tachycardia, myocardial infarction, congestive heart failure, and cardiac arrhythmias. It’s also approved for use in conditions such as essential tremors, hyperthyroidism, glaucoma, and prevention of migraines.  

Beta-blockers are available in many forms, including oral, IV, intramuscular injection, and ophthalmic drops. Starting dosage and route are determined by the health condition being treated [8]. 

 

Common side effects of beta-blockers include: 

  • Bradycardia 
  • Hypotension 
  • Dizziness 
  • Feeling tired 
  • Nausea 
  • Dry mouth 
  • Sexual Dysfunction  

[17] 

 

This class of medications can also lead to more severe adverse effects such as orthostatic hypotension, bronchospasm, shortness of breath, hyperglycemia, and increased risk of QT prolongation, torsades de pointes, and heart block [8]. Healthcare providers should avoid prescribing non-selective beta-blockers to patients with asthma. Instead, they can prescribe cardio-selective beta-blockers for patients with asthma.  

Additionally, the use of beta-blockers is contraindicated in patients with a history of bradycardia, hypotension, Raynaud disease, QT prolongation, or torsades de pointes. Healthcare providers must encourage patients to monitor their heart rate and blood pressure and follow administration parameters before taking beta-blockers daily since it decreases their heart rate.  

Overdose of beta-blockers is life-threatening and healthcare providers must discuss the symptoms of an overdose and the need for emergency care [8].

Angiotensin-converting Enzyme Inhibitors 

Angiotensin-converting enzyme (ACE) inhibitors prevent the body from producing angiotensin, a hormone that causes vasoconstriction. As angiotensin production is reduced, this allows the blood vessels to dilate and therefore lowers blood pressure [3].  

Moreover, ACE inhibitors act specifically on the renin-angiotensin-aldosterone system (RAAS) by preventing the conversion of angiotensin I to angiotensin II. It also works to decrease aldosterone, which in turn, decreases sodium and water reabsorption [9]. 

ACE inhibitors usually end in the suffix -pril and some common examples include lisinopril, benazepril, enalapril, and captopril, and they usually end in the suffix [3].  

While ACE inhibitors are approved for treating hypertension, they are also FDA-approved for other uses or combination therapies for medical conditions such as: 

  • Systolic heart failure 
  • Chronic kidney disease 
  • ST-elevated myocardial infarction 

One non-approved FDA use is treatment of diabetic nephropathy [9]. This class of medication is available in oral, and IV forms, and dosages are dependent on clinical guidelines, underlying medical conditions, and route.  

ACE inhibitors have common side effects, with some including: 

  • Dry cough 
  • Dizziness 
  • Hypotension [9]. 

 

This medication can also lead to adverse effects, such as syncope, angioedema, and hyperkalemia [9]. As angioedema is an adverse effect, healthcare providers should understand this class of medications is contraindicated in patients with a history of hypersensitivity to ACE inhibitors.  

Additionally, ACE inhibitors are contraindicated in patients with aortic valve stenosis, hypovolemia, and during pregnancy. Individuals with abnormal kidney function should have renal function and electrolyte values monitored. If a patient develops a chronic dry cough, then the healthcare provider should consider another antihypertensive medication class by following current guidelines [9].

Angiotensin II Receptor Blockers 

Similar to ACE inhibitors, Angiotensin II Receptor Blockers (ARBs) act on the RAAS by binding to angiotensin II receptors and thus block and reduce the action of angiotensin II. Again, this reduces blood pressure by causing blood vessel dilation and decreasing sodium and water reabsorption [11]. ARBs typically end in the suffix -artan and common names are losartan, valsartan, and Olmesartan [3]. Oral and IV routes of the medication are available and again, dosages are dependent on the medication specifically and form [11]. 

All ARBs are FDA-approved for the treatment of hypertension, but a select few are approved for treating other medical conditions, such as: 

  • Candesartan for heart failure 
  • Irbesartan for diabetic nephropathy 
  • Losartan for proteinuria and diabetic nephropathy 
  • Telmisartan for stroke and myocardial infarction prevention 
  • Valsartan for heart failure and reduction of mortality in patients with left ventricular dysfunction [11]. 

Although not as common as ACE inhibitors, two side effects of ARBs are dry cough and angioedema.  

 

Other common side effects include: 

  • Dizziness 
  • Hypotension 
  • Hyperkalemia  

[11] 

 

Contraindications for use are if the patient is pregnant or has renal impairment or failure. If a patient is on an ARB, the healthcare provider should closely monitor lab values for electrolyte imbalances and kidney function.  

Additionally, if a patient is taking lithium, ARBs can increase lithium concentration and therefore, lithium blood concentration should be frequently checked [11].

Calcium Channel Blockers 

Calcium channel blockers (CCBs), also known as calcium channel antagonists, act by preventing calcium from entering the smooth vascular and heart muscles. In turn, this reduces heart rate and causes vasodilation [3].  

They are further divided into two major categories, non-dihydropyridines and dihydropyridines, where there are differences in the mechanism of action. Non-dihydropyridines inhibit calcium from entering the heart’s sinoatrial and atrioventricular nodes and thus cause a cardiac conduction delay and reduce cardiac contractility.  

Alternatively, dihydropyridines do not directly affect the heart but do act as a peripheral vasodilator leading to lowered blood pressure. Both categories are metabolized by the CYP3A4 pathway [15]. 

Names of non-dihydropyridine CCBs are verapamil and diltiazem. Dihydropyridine CCBs typically end in the suffix  -pine and common names are amlodipine and nicardipine. Both categories are available via oral and IV routes for administration. Oral dosages of non-dihydropyridine CCBs start at 30mg daily and dihydropyridine CCBs start at 30mg daily for immediate release [15].  

Calcium channel blockers can be used to treat other medical conditions in addition to hypertension and include: 

  • Coronary spasm 
  • Angina pectoris 
  • Supraventricular dysrhythmias 
  • Pulmonary hypertension 
  • Hypertrophic cardiomyopathy 

Non-dihydropyridine CCBs can cause side effects like bradycardia, and constipation, while dihydropyridine CCBs can cause: 

  • Headaches 
  • Feeling lightheaded 
  • Leg swelling [15]. 

Both categories pose the risk of potential hypotension and bradycardia, so healthcare providers should closely monitor the patient’s blood pressure and heart rate when initiating or titrating the dosage.  

Also, an overdose of this medication can lead to cardiac conduction delays, complete heart block, and cardiovascular collapse. Patients with possible symptoms of overdose should be sent to the emergency room immediately.  

Additionally, healthcare providers should avoid prescribing CCBs to people with heart failure and sick sinus syndrome [15].

Selective Alpha-1 Blockers 

Selective alpha-1 blockers act on the body’s sympathetic nervous system to lower blood pressure. They prevent norepinephrine from binding to the alpha-1 receptors of the sympathetic nervous system, causing smooth muscle relaxation and vasodilation which leads to lowered blood pressure [18]. 

Selective alpha-1 blockers are available via the oral route, end in the suffix -osin and examples are doxazosin, terazosin, and prazosin [3]. They are FDA-approved for the treatment of hypertension but are not considered first-line therapy. Additionally, this class of medications may be used to treat benign prostatic hyperplasia. Dosages can start as low as 1mg daily depending on the drug selected. 

Common side effects include: 

  • Hypotension 
  • Tachycardia 
  • Dizziness 
  • Headache 
  • Weakness [18]. 

 

As selective alpha-1 blockers can lead to orthostatic hypotension, the healthcare provider should instruct the patient to take this medication at night. They should also avoid prescribing to the elderly population when able because of hypotension and increased fall risk [18].

Alpha-2 Receptor Agonists 

Alpha-2 receptor agonists work by decreasing the activity of the sympathetic nervous system to lower blood pressure. It inhibits adenylyl cyclase and decreases the formation of cyclic adenosine monophosphate (cAMP). Alpha-2 agonists also cause vasodilation by reducing the amount of available cytoplasmic calcium [20].  

This class of medications is typically administered via oral route but is also available in intravenous and transdermal forms. Two FDA-approved alpha-2 agonists for hypertension treatment are methyldopa and clonidine and dosages are dependent on the name and route.  

Methyldopa is commonly prescribed to patients with hypertension and who are pregnant since it’s safe [20]. 

 

Common side effects of alpha-2 receptor agonists are: 

  • Dry mouth 
  • Drowsiness 
  • Fatigue 
  • Headache 
  • Sexual dysfunction [3]. 

Contraindications for use are orthostatic hypotension and autonomic disorders. Healthcare providers must avoid prescribing alpha-2 receptor agonists to individuals taking phosphodiesterase inhibitors [20].

Vasodilators 

Vasodilators lower blood pressure by dilating the body’s blood vessels. It binds to the receptors of the blood vessel’s endothelial cells, releasing calcium. Calcium stimulates nitric oxide synthase (NO synthase), eventually converting to L-arginine to nitric oxide. As nitric oxide is available, this allows for GTP to convert to cGMP, and causes dephosphorylation of the myosin and actin filaments. As this occurs, the blood vessels’ smooth muscles relax, leading to vasodilation and lowered blood pressure.  

Common vasodilators that act via this pathway are nitrates and minoxidil. Hydralazine is another vasodilator, but the mechanism of action is unknown [10]. 

Available forms of vasodilators are sublingual, oral, and intravenous. Similar to other classes of antihypertensives, vasodilator dosages depend on the form and treatment setting [10].  

Nitrovasodilators like nitroprusside and nitroglycerin are used during hypertensive emergencies. Hydralazine is used for severe hypertension for the prevention of eclampsia or intracranial hemorrhage and minoxidil for resistant hypertension [10] [3]. 

 

Side effects for each will vary, but nitrates commonly cause: 

  • Reflex tachycardia 
  • Headache 
  • Orthostatic hypotension  

[10] 

 

Common side effects of hydralazine are headaches, heart palpitations, and myalgias. Minoxidil causes excessive hair growth, weight gain, and fluid retention [3]. Additionally, nitroprusside can potentially cause cyanide toxicity.  

Vasodilators have varying degrees of contraindications, such as nitrates are avoided in patients with an inferior myocardial infarction. Hydralazine should not be given to patients with coronary artery disease, angina, or rheumatic heart disease. Healthcare providers should be aware of contraindications and monitor patients’ blood pressure and potential side effects [10].

Combination Antihypertensives 

Many antihypertensive medications come in combined forms, such as ACE inhibitors and thiazide diuretics, beta-blockers and diuretics, or calcium channel blockers and ACE inhibitors. The mechanism of action for combination antihypertensives depends on the blend of medications [3]. 

Considerations for Prescribers 

This section reviews potential considerations when prescribing antihypertensives. 

When prescribing antihypertensive medications, there are several factors that healthcare providers must consider. The route is typically determined by the healthcare setting and dosage by the underlying treatment goals. Again, healthcare providers should follow current guidelines when initiating or titrating antihypertensive medications.  

Healthcare providers must complete a thorough health history, and review lab values, and contraindications as mentioned above. Monitoring kidney function and electrolyte values is imperative while any patient is taking antihypertensive medications.  

While a single antihypertensive medication is recommended for initial treatment, there are some scenarios where combination therapy or combination antihypertensives are recommended [14]. 

Healthcare providers should also discuss the potential side effects of antihypertensives with patients and what to do if they are experiencing symptoms. For instance, if a patient reports syncope, they should be advised to go to the emergency room or be seen immediately for further evaluation. Also, healthcare providers must encourage patients to monitor their heart rate and blood pressure at home and abide by administration parameters.  

For example, instruct patients who are taking beta-blockers to measure their blood pressure and heart rate before taking their medication. If their heart rate is below 60 beats per minute, then they should not take the medication [14].  

If a patient is experiencing side effects from an antihypertensive medication, then another alternative should be selected.

Upcoming Research 

This section reviews upcoming research and medications for hypertension treatment. 

Research on antihypertensive medications has slowed throughout the years. Some clinical trials were performed on the potential of endothelin receptor antagonists to reduce hypertension. However, some studies found several unwanted side effects, and thus clinical use was stopped for safety reasons.  

An endothelin-A and endothelin-B receptor blocker, called aprocinentan, has shown promise for the treatment of resistant hypertension by lowering blood pressure and decreasing vascular resistance.  

Research on sodium-glucose transport protein (SGLT2) inhibitors, which are typically used for the treatment of type II diabetes mellitus, is also ongoing. SGLT2 inhibitors may promote blood pressure reduction through diuresis and reduce sympathetic tone [21].

Migraine Medications 

Understanding the various classes of migraine medications is like having a diverse toolkit to address the complexities of this neurological disorder. By exploring the different classes of medications, healthcare professionals can tailor their approach and make informed decisions based on individual patient profiles and specific migraine characteristics (20).  

It is crucial to recognize that migraine medications are not one-size-fits-all. Each patient is unique, and their response to medications may vary. Recent literature by (12) emphasizes the importance of an individualized approach when considering the best medication for each patient. Here’s a list of migraine medications in addition to important details to consider:  

Triptans  

Triptans are a class of medications specifically designed for the acute treatment of migraines. According to (39), they are not meant for preventive use but are highly effective in providing relief during an ongoing migraine attack. They work by narrowing blood vessels and inhibiting the release of certain chemicals in the brain associated with migraine symptoms (39). Let’s see more details below as described by (7), (39), (29). 

Drug Class 

Belonging to the serotonin (5-HT) receptor agonists class, Triptans modulate the effects of serotonin receptors in the brain. The various types of Triptans include Sumatriptan, Rizatriptan, Eletriptan, and others. Each Triptan has unique characteristics, such as the onset of action and duration, allowing healthcare professionals to tailor prescriptions based on individual patient needs. 

Benefits 

Triptans offer several benefits in the management of migraines. One of the primary advantages is their ability to provide rapid and effective relief from migraine symptoms, including headache pain, nausea, and sensitivity to light and sound. The prompt onset of action is particularly valuable for individuals aiming to resume their daily activities quickly. Triptans are available in various formulations, including oral tablets, nasal sprays, and injectables, allowing for flexibility in administration. 

Side Effects 

While generally well-tolerated, Triptans may cause side effects. Common side effects include mild sensations of warmth or tingling, dizziness, and tightness or pressure in the chest. It is crucial for healthcare professionals to consider the patient's medical history and potential contraindications, such as cardiovascular issues, before prescribing Triptans. In rare cases, more severe side effects like chest pain and changes in heart rate may occur, necessitating immediate medical attention. 

Clinical Effects 

The clinical effects of Triptans are profound, offering relief to individuals experiencing acute migraine attacks. The primary outcomes include: 

  • Pain Relief: Triptans are highly effective in reducing the intensity of migraine-associated pain. By targeting the vascular and neuronal components of migraines, these drugs provide rapid relief, allowing patients to resume their normal activities. 
  • Relief of Associated Symptoms: Beyond pain relief, Triptans address accompanying symptoms such as nausea, photophobia, and phonophobia. This comprehensive effect enhances the overall patient experience during a migraine episode. 
  • Prevention of Migraine Progression: Triptans, when administered early in the migraine attack, can prevent the progression of the headache phase to more severe stages. This early intervention is crucial for optimizing outcomes and minimizing the impact of migraines on daily life. 
  • Improvement in Functional Impairment: Migraines often result in functional impairment, limiting individuals' ability to perform daily tasks. Triptans restore functional capacity, allowing patients to regain control over their activities. 
Nonsteroidal Anti-Inflammatory Drugs (NSAIDSs)  

Nonsteroidal anti-inflammatory drugs, commonly known as NSAIDs, constitute a class of medications used in the treatment of migraines. According to (6), these drugs are characterized by their anti-inflammatory, analgesic, and antipyretic properties. NSAIDs are versatile, as they are not exclusively used for migraines but are also used for various other pain and inflammatory conditions (6). Let’s see more details below as described by (25), (40), (6) and (28). 

Drug Class 

NSAIDs encompass a broad class of medications, including well-known examples such as ibuprofen, naproxen, and aspirin. They function by inhibiting enzymes called cyclooxygenases (COX), thereby reducing the production of inflammatory prostaglandins. This mechanism provides relief from pain and mitigates inflammation associated with migraines. 

Benefits 

The primary benefit of NSAIDs in migraine management lies in their ability to alleviate pain and reduce inflammation. They are particularly effective for individuals experiencing mild to moderate migraines. NSAIDs offer a rapid onset of action, making them suitable for individuals seeking prompt relief. Additionally, these medications are available over-the-counter in many formulations, providing accessibility for patients. 

Side Effects 

While NSAIDs are generally well-tolerated, they may cause side effects, especially with prolonged or excessive use. Common side effects include gastrointestinal issues such as stomach upset or ulcers. Healthcare professionals need to consider a patient's medical history, including conditions like gastric ulcers, before prescribing NSAIDs. In rare cases, more severe side effects like cardiovascular events may occur, emphasizing the importance of cautious use. 

Clinical Effects 

The clinical effects of NSAIDs in migraine management encompass various aspects. Here’s a list of some of them.

Pharmacokinetics 

Understanding the pharmacokinetics of migraine management medications enables healthcare professionals to tailor treatment plans based on individual patient characteristics, ensuring maximum therapeutic benefit. Let’s get into more details for each of the medications listed above: 

Triptans 

Absorption 

Triptans exhibit distinct pharmacokinetic properties that influence their efficacy and onset of action. Following oral administration, Triptans are absorbed through the gastrointestinal tract and the rate of absorption varies among different Triptans, contributing to differences in their clinical profiles. (39) 

Distribution 

Upon absorption, Triptans undergo distribution to reach target sites in the body, primarily the central nervous system. Their lipophilic nature allows them to penetrate the blood-brain barrier, enabling interaction with serotonin receptors implicated in migraine pathophysiology. The distribution of Triptans influences their ability to exert effects centrally and peripherally. (39) 

Metabolism 

Metabolism is a crucial aspect of triptan pharmacokinetics, occurring predominantly in the liver. The enzyme responsible for triptan metabolism is monoamine oxidase-A (MAO-A). (39) 

Excretion 

The final phase in the pharmacokinetic journey of Triptans is excretion, primarily through renal and biliary routes. Renal excretion eliminates the unchanged drug and its metabolites, while biliary excretion expels metabolites via the bile into the gastrointestinal tract. The interplay between metabolism and excretion contributes to the overall pharmacokinetic profile of Triptans. Variations in renal function may influence the elimination of the half-life of certain Triptans, impacting the duration of their therapeutic effect. (39)

Asthma Treatment and Monitoring

Introduction   

When hearing the phrase asthma, what comes to mind? If you're an advanced practice registered nurse (APRN) with prescriptive authority, you've definitely heard of asthma before. Even as a nurse or maybe before nursing school, conversations about prescription drug use and respiratory health existed every so often.

Presently, patients seek guidance and information on various health topics from APRNs, including medication management and respiratory health. The information in this course will serve as a valuable resource for APRNs with prescriptive authority of all specialties, education levels, and backgrounds, to learn more about medications that can treat and manage asthma.

Defining Asthma 

What Is Asthma? 

Asthma is a non-communicable chronic health condition that affects the airways of the lungs and affects millions of people nationwide. Asthma is often diagnosed in childhood and can resolve in adulthood or continue for the rest of a patient's life. Several studies postulate the cause of asthma, but there is no definitive cause.  

Genetics, age, environmental exposures, smoking, and a history of allergies are thought to play a role in asthma severity and development. Clinical presentation of asthma often includes trouble breathing, chronic airway inflammation, and airway hyperresponsiveness. Assessment for asthma often includes patient history, clinical presentation, spirometry testing, and pulmonary function tests (PFTs). 

 

What Are the Stages of Asthma? 

Since asthma is a chronic condition, several established guidelines can be used to determine the severity of asthma and explore possible medication options. Depending on the stage of asthma and patient response to existing therapy, treatment and management vary.  

The four stages of asthma include intermittent, mild, moderate, and severe. Based on the 2020 National Asthma Education and Prevention Program (NAEPP) guidelines, here is the standard criteria for what constitutes each stage of asthma (2). 

 

Intermittent asthma is characterized with the following clinical presentation and assessment (2): 

  • Patient history of respiratory symptoms, such as cough, trouble breathing, wheezing, or chest tightness <2 times a week 
  • Asthmatic flare-ups are short-lived with varying intensity  
  • Symptoms at night are <2 a month 
  • No asthmatic symptoms between flare-ups 
  • Lung function test FEV 1 at >80% above normal values 
  • Peak flow has <20% variability am-to-am or am-to-pm, day-to-day 

 

Mild persistent asthma is characterized with the following clinical presentation and assessment (2): 

  • Patient history of respiratory symptoms, such as cough, trouble breathing, wheezing, or chest tightness 3-6 times a week 
  • Asthmatic flare-ups may affect activity level and can vary in intensity 
  • Symptoms at night are 3-4 times a month 
  • Lung function test FEV1 is >80% above normal values 
  • Peak flow has less than 20-30% variability 

 

Moderate persistent asthma is characterized with the following clinical presentation and assessment (2): 

  • Patient history of respiratory symptoms, such as cough, trouble breathing, wheezing, or chest tightness daily 
  • Asthmatic flare-ups may affect activity level and can vary in intensity 
  • Symptoms at night are >5 times a month 
  • Lung function test FEV1 is 60%-80% of normal values 
  • Peak flow has more than 30% variability 

 

Severe persistent asthma is characterized with the following clinical presentation and assessment (2): 

  • Patient history of respiratory symptoms, such as cough, trouble breathing, wheezing, or chest tightness continuously  
  • Asthmatic flare-ups affect activity level and often vary in intensity 
  • Asthmatic symptoms at night are constant 
  • Lung function test FEV1 is <60% of normal values 
  • Peak flow has more than 30% variability 

 

Based on patient history, clinical presentation, and these criteria, treatment can be administered to decrease the symptoms of the patient. If a patient presents with symptoms that are outside of your scope of work or understanding, you can always refer patients to a pulmonologist or asthma specialist.  

Often times, more severe cases of asthma and asthma emergencies require increased frequency and dosing of asthma-related medications. Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history, pulmonary function, and health history prior to prescribing asthma medications (1). 

 

What Are Asthmatic Emergencies? 

Asthmatic emergencies are if a patient has asthma symptoms that are beyond what they typically experience and are unable to function without immediate medical intervention. Asthma emergencies can occur as a result of a patient being unable to access their asthmatic medications, being exposed to a possible allergen, or being under increased stress on the body.  

Asthmatic emergencies often require collaborative medical intervention, increased dosages of medications discussed below, and patient education to prevent future asthmatic emergencies (1).  

 

What If Asthma Is Left Untreated? 

Depending on the clinical presentation and severity of asthma, asthma can cause several long-term complications if left untreated. If asthma is not properly managed, several complications, such as chronic obstructive pulmonary disease (COPD), decreased lung function, permanent changes to the lungs' airways, and death can occur (1, 2).  

 

 

Defining Asthma Medications 

 

What Are Commonly Used Medications to Manage Asthma? 

Commonly used medications to manage asthma include inhaled corticosteroids, oral corticosteroids, short-acting beta agonists (SABAs), long-acting beta agonists (LABAs), long-acting muscarinic antagonists (LABAs), adenosine receptor antagonists, leukotriene modifiers, mast cell stabilizers, and monoclonal antibodies. The dosage, frequency, amount of asthma management medications, and medication administration route can all vary depending on clinical presentation, patient health history, and more.  

 

How and Where are Asthma Medications Used? 

Asthma medications can be used routinely or as needed for management of asthma symptoms depending on the patient. Asthma medications can be used at home, in public, and in health care facilities. Depending on the specific asthma medication and dosage, these medications can be taken by mouth, by an external device, such as an inhaler, via subcutaneous injection, or via intravenous solution (1).  

 

What Are the Clinical Criteria for Prescribing Asthma Medication? 

Clinical criteria for prescribing asthma medication can depend on the clinical presentation of a patient. Assessment of lung health and patient history are essential to determining the dosage and medications needed for adequate asthmatic symptom control.  

Clinical guidelines from reputable organizations, such as the National Asthma Education and Prevention Program (NAEPP), the National Institutes of Health (NIH), the Global Initiative for Asthma (GINA), and the American Academy of Family Physicians (AAFP) can provide insight into the latest recommendations for asthma management (1, 2). In addition, local laws or health departments might have recommendations for asthma medication guidelines.  

 

What Is the Average Cost for Asthma Medications? 

Cost for asthma medications can significantly vary depending on the type of medication, insurance, dosage, frequency, medication administration route, and other factors. Cost is among a leading reason why many patients cannot maintain their medication regime (3). If cost is a concern for your patient, consider reaching out to your local pharmacies or patient care teams to find cost effective solutions for your patients.

Inhaled Corticosteroids Pharmacokinetics 

Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.  

 

Drug Class – Inhaled Corticosteroids  

Commercially available inhaled corticosteroids include: ciclesonide (Alvesco HFA), fluticasone propionate (Flovent Diskus, Flovent HFA, Armon Digihaler), budesonide (Pulmicort Flexhaler), beclomethasone dipropionate (QVAR RediHaler), fluticasone furoate (Arnuity Ellipta), and mometasone furoate (Asmanex HFA, Asmanex Twisthaler).  

Clinical criteria for prescribing an inhaled corticosteroid includes adherence to the latest clinical guidelines, patient medical history, patient clinical presentation, and drug availability (4).  

 

Inhaled Corticosteroids Method of Action 

Inhaled corticosteroids have an intricate mechanism of action involving several responses to the immune system. Inhaled corticosteroids decrease the existing initial inflammatory response by decreasing the creation and slowing the release of inflammatory mediators. Common inflammatory mediators include histamine, cytokines, eicosanoids, and leukotrienes. Inhaled corticosteroids can also induce vasoconstrictive mechanisms, which, as a result, can lead to less blood flow, resulting in less discomfort and edema (4).  

In addition to anti-inflammatory properties, inhaled corticosteroids can create a localized immunosuppressive state that limits the airways' hypersensitivity reaction, which is thought to reduce bronchospasms and other asthma-associated symptoms. It is important to note that inhaled corticosteroids often do not produce therapeutic effects immediately, as many patients may not see a change in their asthma symptoms for at least a week after beginning inhaled corticosteroid therapy (4).  

 

Inhaled Corticosteroids Side Effects 

Every medication has the possibility of side effects, and inhaled corticosteroids are no exception. Common side effects of inhaled corticosteroids include oral candidiasis (thrush), throat irritation, headache, and cough.  

Patient education about rinsing their mouth and oral hygiene after use is essential to avoid the possibility of thrush and other oral infections and irritations. More severe side effects can include prolonged immunosuppression, reduction in bone density, and adrenal dysfunction (4).  

 

Inhaled Corticosteroids Alternatives 

While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with inhaled corticosteroids, so additional medication, increased dosage, a change in frequency, or a new medication class might need to be considered (4).

Oral Corticosteroids Pharmacokinetics 

Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.  

 

Drug Class – Oral Corticosteroids  

Commercially available oral corticosteroids include methylprednisolone, prednisolone, and prednisone. Clinical criteria for prescribing an oral corticosteroid includes adherence to the latest clinical guidelines, patient medical history, patient clinical presentation, and drug availability (4).  

 

Oral Corticosteroids Method of Action 

Methylprednisolone and prednisolone have a method of action as intermediate, long-lasting, synthetic glucocorticoids, have COX-2 inhibitory properties, and inhibit the creation of inflammatory cytokines (5). 

Prednisone is a prodrug to prednisolone and has anti-inflammatory and immunomodulating glucocorticoid properties. Prednisone has a method of decreasing inflammation by reversing increased capillary permeability and suppressing the movement of certain leukocytes (6).  

 

Oral Corticosteroids Side Effects 

Every medication has the possibility of side effects, and oral corticosteroids are no exception. Methylprednisolone and prednisolone have possible side effects of skin changes, weight gain, increased intraocular pressure, neuropsychiatric events, neutrophilia, immunocompromised state, fluid retention, and GI upset.  

Consider monitoring symptoms and overall health of patients on systemic corticosteroids to assess for long-term side effects (5). Prednisone has possible side effects of changes in blood glucose, changes in sleep habits, changes in appetite, increased bone loss, an immunocompromised state, changes in adrenal function, and changes in blood pressure (6).  

 

Oral Corticosteroids Alternatives 

While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with oral corticosteroids, so additional medication, increased dosage, a change in frequency, or a new medication class might need to be considered (6).

Short-Acting Beta Agonists (SABAs)  

Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.  

 

Drug Class – SABAs 

Common commercially available SABAs include albuterol sulfate (ProAir HFA, Proventil HFA, Ventolin HFA), albuterol sulfate inhalation powder (ProAir RespiClick, ProAir Digihaler), levalbuterol tartrate (Xopenex HFA), and levalbuterol hydrochloride (Xopenex) (4). 

 

SABAs Method of Action 

Short-acting beta-agonists (SABAs) have a rapid onset as broncho-dilating medications. SABAs, especially albuterol in emergent situations, are used often to quickly relax bronchial smooth muscle from the trachea to the bronchioles through action on the β2-receptors.  

While SABAs are effective bronchodilators in the short term for asthma symptoms, SABAs do not affect the underlying mechanism of inflammation. As a result, SABAs are often used for short-acting intervals, such as few hours, and have limited capabilities to prevent asthma exacerbations alone (4). SABAs can be administered via meter-dosed inhalers, intravenous, dry powder inhalers, orally, subcutaneously, or via nebulizer.  

 

SABAs Side Effects 

Every medication has the possibility of side effects, and SABAs are no exception. Because of the beta receptor agonisms, possible SABA side effects include increased heart rate, chest pain, chest palpitations, body tremors, and nervousness (4). Because of the short half-life of SABAs, chronic side effects are not typically observed.  

 

SABAs Alternatives 

While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with SABAs, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Long-Acting Beta Agonists (LABAs) 

Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.  

 

Drug Class – LABAs 

Common commercially available LABAs are salmeterol and formoterol (7).  

 

LABAs Method of Action 

Long-acting beta-agonists (LABAs) have a rapid onset like SABAs, but also have a longer half-life. LABAs are used often as asthma maintenance medications to relax bronchial smooth muscle from the trachea to the bronchioles through action on the β2-receptors. While SABAs are effective bronchodilators in the short term for asthma symptoms, LABAs are effective bronchodilators in the long term for asthma symptoms.  

Like SABAs, LABAs do not affect the underlying mechanism of inflammation. LABAs can be administered via meter-dosed inhalers, intravenous, dry powder inhalers, orally, subcutaneously, or via nebulizer. LABAs are often effective for 12-hour durations (7). 

 

LABAs Side Effects 

 

Every medication has the possibility of side effects, and LABAs are no exception. Like SABAs, because of the beta receptor agonisms, possible LABA side effects include increased heart rate, chest pain, chest palpitations, body tremors, and nervousness (7). Other more prolonged side effects can include changes in blood glucose levels and changes in potassium levels with prolonged LABA use (7).  

 

LABAs Alternatives 

While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with LABAs, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).  

In addition, there are combination inhaled corticosteroid/LABA medications that can be considered, such as fluticasone propionate and salmeterol (Advair Diskus, Advair HFA, AirDuo Digihaler, AirDuo RespiClick, Wixela Inhub), fluticasone furoate and vilanterol (Breo Ellipta), mometasone furoate and formoterol fumarate dihydrate (Dulera), and budesonide and formoterol fumarate dihydrate (Symbicort) (4).

Long-Acting Muscarinic Antagonists (LAMAs) 

Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.  

 

Drug Class – LAMAs 

Common commercially available LAMAs include two inhalation powders via inhalers known as tiotropium bromide (Spiriva Respimat) and fluticasone furoate, umeclidinium, and vilanterol (Trelegy Ellipta) (4).  

 

LAMAs Method of Action 

Both drugs mentioned above are long-acting muscarinic antagonists (LAMAs). LAMAs work to alleviate asthmatic symptoms by antagonizing the type 3 muscarinic receptors in bronchial smooth muscles, resulting in relaxation of muscles in the airway (4). Because LAMAs are long-acting, they are not recommended for cases of acute asthma exacerbations or asthmatic emergencies (4). 

 

LAMAs Side Effects 

Possible LAMA side effects include urinary retention, dry mouth, constipation, and glaucoma (4).  

 

LAMAs Alternatives 

While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with LAMAs, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Adenosine Receptor Antagonists Pharmacokinetics 

Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.  

 

Drug Class – Adenosine Receptor Antagonists 

The commercially available adenosine receptor antagonist for asthma management is theophylline as a pill or intravenous (8). 

  

Adenosine Receptor Antagonists Method of Action 

The method of action for theophylline is acting as a nonselective adenosine receptor antagonist, acting as a competitive, nonselective phosphodiesterase inhibitor, and reducing airway responsiveness to histamine, allergens, and methacholine (8).  

 

Adenosine Receptor Antagonists Side Effects  

Common side effects of theophylline include GI upset, headache, dizziness, irritability, and arrythmias (8).  

 

Adenosine Receptor Antagonists Alternatives 

While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with theophylline, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Leukotriene Modifiers Pharmacokinetics 

Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.  

 

Drug Class – Leukotriene Modifiers 

Commercially available leukotriene modifiers include montelukast (Singular) and zafirlukast (Accolate) as oral pills taken once a day. Zileuton (Zyflo CR) is a 5-lipoxygenase inhibitor that also modifies leukotriene activity (4).  

 

Leukotriene Modifiers Method of Action 

Montelukast and zafirlukast work to control asthma-related symptoms by targeting leukotrienes, which are eicosanoid inflammatory markers. Montelukast works in particular by blocking leukotriene D4 receptors in the lungs, thus allowing decreased inflammation in the lungs and increased relaxation of lung smooth muscle (9).  

Zafirlukast works by being a competitive antagonist at the cysteinyl leukotriene-1 receptor (CYSLTR1) (10). Zileuton is a 5-lipoxygenase inhibitor, in which 5-lipoxygenase is needed for leukotriene creation. Blocking 5-lipoxygenase decreases the formation of leukotrienes at several receptors. As a result of decreased leukotriene production, there is decreased inflammation, decreased mucus secretion, decreased bronchoconstriction (11). 

 

Leukotriene Modifiers Side Effects 

Possible side effects of montelukast include headaches, GI upset, and upset. Neuropsychiatric events, such as nightmares, changes in sleep, depression, and suicidal ideation are more severe side effects associated with montelukast.  

Possible side effects of zafirlukast include headache, GI upset, and hepatic dysfunction (9).  

Possible side effects of zileuton include hepatic dysfunction, changes in sleep, changes in mood, headaches, and GI upset. When the leukotriene modifiers, neuropsychiatric side effects are to be monitored for in particular, especially for suicidal ideation (9,10,11).  

 

Leukotriene Modifiers Alternatives 

Some patients might not report their symptoms alleviating with leukotriene modifiers, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Mast Cell Stabilizer Pharmacokinetics 

Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.  

 

Drug Class – Mast Cell Stabilizer 

A commercially available mast cell stabilizer is cromolyn available via metered-dose inhaler and nebulizer solution (12).  

 

Mast Cell Stabilizer Method of Action 

Cromolyn has a method of action in which it inhibits the release of inflammatory mediators from cells, such as the release of histamine and leukotrienes (12).  

 

Mast Cell Stabilizer Side Effects 

Every medication has the possibility of side effects, and cromolyn is no exception. Common side effects of cromolyn include dry throat, throat irritation, drowsiness, dizziness, cough, headache, and GI upset (12).  

 

Mast Cell Stabilizer Alternatives 

While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with mast cell stabilizers, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Monoclonal Antibody Pharmacokinetics 

Health care provider professional discretion and patient condition should guide therapy. Consider reviewing a patient's medication history and health history prior to prescribing asthma medications.  

 

Drug Class – Monoclonal Antibody 

Commercially available monoclonal antibodies include Omalizumab (Xolair), mepolizumab (Nucala), reslizumab (Cinqair), benralizumab (Fasenra), dupilumab (Dupixent), and tezepelumab-ekko (Tezspire). Omalizumab, mepolizumab, benralizumab, dupilumab, and texepelumab-ekko are available via subcutaneous injection. Reslizumab is available via intravenous solution (4). 

 

Monoclonal Antibody Method of Action 

Omalizumab is an anti-IgE monoclonal antibody that works by inhibiting the binding of IgE to mast cells and basophils. As a result of decreased bound IgE, activation and release of mediators, such as histamine, in the allergic response are decreased (13).  

Mepolizumab, reslizumab, and benralizumab are interleukin (IL)-5 antagonists. These IL-5 antagonists inhibit IL-5 signaling, allowing for a decrease in the creation and survival of eosinophils. However, the full method of action for IL-5 antagonists is still unknown, as more evidence-based research is needed (4, 15).  

Dupilumab is an IgG4 antibody that inhibits IL-4 and IL-13 signaling by binding to the IL-4Rα subunit. This inhibition of the IL-4Rα subunit allows for the decrease of IL-4 and IL-13 cytokine-induced inflammatory responses (14). 

 

Tezepelumab-ekko is an IgG antibody that binds to the thymic stromal lymphopoietin (TSLP) and prevents TSLP from interacting with the TSLP receptor. Blocking TSLP decreases biomarkers and cytokines associated with inflammation. Knowing this, the full method of action for Tezepelumab-ekko is still unknown, as more evidence-based research is needed4,15 

 

Monoclonal Antibody Side Effects 

Possible side effects of omalizumab include injection site reactions, fracture, anaphylaxis, headache, and sore throat (13). Possible side effects of mepolizumab, reslizumab, and benralizumab include injection site reactions, headache, and hypersensitivity reactions (4). Possible side effects of dupilumab include joint aches, injection site reactions, and headache (14). Possible side effects of tezepelumab-ekko include injection site reactions and headache (14). 

 

Monoclonal Antibody Alternatives 

While there are clinical criteria for asthma medications, everyone can respond to medications differently. Some patients might not report their symptoms alleviating with monoclonal antibodies, so additional medication, increased dosage, a change in frequency, or an additional medication class might need to be considered (4).

Nursing Considerations 

Nurses remain the most trusted profession for a reason, and APRNs are often pillars of patient care in several health care settings. Patients turn to nurses for guidance, education, and support. While there is no specific guideline for the nurses' role in asthma education and management, here are some suggestions to provide quality care for patients currently taking medications to manage asthma or concerned about possibly having asthma. 

  • Take a detailed health history. Often times, respiratory symptoms, such as a cough or trouble breathing, are often dismissed in health care settings, or seen as "common symptoms with everyone." If a patient is complaining of symptoms that could be related to asthma, inquire more about that complaint.  

Ask about how long the symptoms have lasted, what treatments have been tried, if these symptoms interfere with their quality of life, and if anything alleviates any of these symptoms. If you feel like a patient's complaint is not being taken seriously by other health care professionals, advocate for that patient to the best of your abilities.  

  • Review medication history at every encounter. Often times, in busy clinical settings, reviewing health records can be overwhelming. Millions of people take asthma medications at varying dosages, frequencies, and times of day. Many people with asthma take more than one medication to manage their symptoms.  

Ask patients how they are feeling on the medication, if their symptoms are improving, and if there are any changes to medication history.  

  • Be willing to answer questions about asthma, respiratory health, and medication options. Society stigmatizes open discussions of prescription medication and can minimize symptoms of asthma, such as a chronic cough.  

There are many people who do not know about medication options or the long-term effects of undiagnosed or poorly managed asthma. Be willing to be honest with yourself about your comfort level discussing topics and providing education on asthma medications and asthma clinical assessment options.  

  • Inquire about a patient's life outside of medications, such as their occupation, living situation, and smoking habits. Household exposures, such as carpets or pets, can trigger asthma. Occupations with high exposure to smoke can also trigger asthmatic symptoms. Smoking, living with someone who smokes, or residing in an area with high levels of pollution can also influence asthma symptoms.  

Discuss possible solutions to help with symptoms, such as improving ventilation, increasing air quality, and mask wearing when possible.  

  • Communicate the care plan to other staff involved for continuity of care. For several patients, especially for patients with severe asthma, care often involves a team of nurses, specialists, pharmacies, and more. Ensure that patients' records are up to date for ease in record sharing and continuity of care. 
  • Stay up to date on continuing education related to asthma medications, as evidence-based information is always evolving and changing. You can then present your new learnings and findings to other health care professionals and educate your patients with the latest information. You can learn more about the latest research on asthma and asthma-related medications by following updates from evidence-based organizations.  

 

How can nurses identify if someone has asthma?  

Unfortunately, it is not always possible to look at someone with the naked eye and determine if they have asthma. While some people might have visible asthmatic symptoms, such as wheezing or trouble breathing, asthmatic clinical presentation can significantly vary from person to person.  

APRNs can identify and diagnose if someone has asthma by taking a complete health history, listening to patient's concerns, and offering pulmonary function testing. 

 

What should patients know about asthma medications?  

Patients should know that anyone has the possibility of experiencing side effects medications for asthma management, just like any other medication. Patients should be aware that if they notice any changes in their mood, experience any sharp headaches, or feel like something is a concern, they should seek medical care.  

Nurses should also teach patients to advocate for their own health in order to avoid untreated or undetected asthma and possible chronic complications from asthma or asthma-related medications.  

 

Here are important tips for patient education in the inpatient or outpatient setting: 

  • Tell the health care provider of any existing medical conditions or concerns (need to identify risk factors). 
  • Tell the health care provider of any existing lifestyle concerns, such as tobacco use, other drug use, sleeping habits, occupation, diet, menstrual cycle changes (need to identify lifestyle factors that can influence asthmatic medication use, asthma severity, and asthma management). 
  • Tell the health care provider if you have any changes in your breathing, such as pain with deep breathing or persistent coughing (potential asthma exacerbation symptoms or possibility of asthma medications not being as effective for treatment). 
  • Tell the nurse of health care provider if you experience any pain that increasingly becomes more severe or interferes with your quality of life. 
  • Keep track of your health, medication use, and health concerns via an app, diary, or journal (self-monitoring for any changes). 
  • Tell the health care provider right away if you are having thoughts of hurting yourself or others (possible increased risk of suicidality is a possible side effect for montelukast use). 
  • Take all prescribed medications as indicated and ask questions about medications and possible other treatment options, such as non-pharmacological options or surgeries. 
  • Tell the health care provider if you notice any changes while taking medications or on other treatments to manage asthma (potential worsening or improving health situation).

Asthma is a chronic condition that affects many people from their childhood to their aging years. As more medications for asthma come onto the market and more evidence-based approaches to asthma and lung care emerge, APRNs will be at the forefront of primary care and asthma care across the lifespan.  

 

Case Study #1 

Susie is a mom to a 15-year-old named Jill. She arrives at the pediatric asthma and allergy specialist practice for a new patient visit. Susie reports that she notices Jill is having trouble sleeping at night and coughing more during the day for the past month. Jill plays soccer with her school, but her mom is concerned about coughing and trouble sleeping interfering with her sports.  

Susie knows that her dad has asthma, and Jill spends a lot of time with her aunt who smokes cigarettes. Jill has a history of generalized anxiety disorder and reports no smoking, no drinking, and no recreational drugs. Jill also wants to learn more about her lung health, as she wants to play soccer professionally one day.  

  • What are some specific questions you’d want to ask about Jill’s coughing and respiratory health? 
  • What are health history questions you would want to highlight? 
  • What are some tests or lab work would you suggest performing?  

 

 

 

Case Study #2 (Continued) 

Susie also shares that she is dating a new partner who vapes in the home, and they recently got a pet puppy in the home. She states that Jill had trouble sleeping at night and coughing a lot when she was younger, but Susie thought Jill grew out of it. Susie wants to learn more about if Jill has asthma like her grandfather, if there are any ways to manage this cough, and if there are any tests that can determine Jill’s lung health in the office today. 

  • What sort of tests can be done in-office to assess pulmonary function? 
  • What sort of environmental exposures can trigger respiratory conditions?  

 

Susie agrees to have Jill do allergy testing and to do an in-office pulmonary function test for teenagers. Jill also wants to learn more about spirometry that you mentioned earlier and how to monitor her health outside of the office since she’s busy with school and soccer and doesn’t want to come to the office every time there’s a problem.  

Susie is open to medication options for Jill but doesn’t want anything that will interfere too much with Jill’s social time with her friends. Susie and Jill also want to know if this is a health condition that Jill will have forever or if Jill will grow out of this.

SSRI Use in Major Depressive Disorder

Introduction   

When hearing the phrase selective serotonin reuptake inhibitors, what comes to mind? If you're an advanced practice registered nurse (APRN) with prescriptive authority, you've heard of SSRIs before. Even as a nurse or maybe before nursing school, conversations about prescription drug use and mental health existed every so often.

Presently, patients seek guidance and information on various health topics from APRNs, including medication management, women's health, and mental health. The information in this course will serve as a valuable resource for APRNs with prescriptive authority of all specialties, education levels, and backgrounds to learn more about SSRIs and major depressive disorder (MDD).  

Defining SSRIs 

What Are SSRIs? 

Selective serotonin reuptake inhibitors, known as SSRIs, are a type of pharmacological drug class. SSRIs have existed for the past several decades as a class of prescription medications that can manage major depressive disorder (MDD) and other mental health conditions (1).

While this course focuses explicitly on SSRI use in MDD management, SSRIs are also Food and Drug Administration (FDA) approved to manage obsessive-compulsive disorder (OCD), panic disorder (PD), post-traumatic stress disorder (PTSD), and social anxiety disorder (SAD). In addition, several off-label uses for SSRI include management for binge eating disorder and menopausal vasomotor symptoms.  

How and Where Are SSRIs Used? 

SSRIs are commonly prescribed to manage MDD and other mood disorders in the U.S. and around the world in pediatric, adult, and geriatric populations (1, 2). SSRIs can be taken by mouth as a pill, capsule, or liquid oral solution. Presently, SSRIs cannot be offered via intravenous, rectal, buccal, or injection routes.  

What Is the Clinical Criteria for Prescribing SSRIs? 

Clinical criteria for prescribing SSRIs can vary depending on the intention for the SSRI. In the case of MDD, several factors can play a role in the clinical criteria for prescribing SSRIs. A patient's adherence to swallowing a pill daily, dosage given the patient's weight, medical history, and MDD concerns, and prior experience with other medications can influence prescribing SSRIs. When considering prescribing SSRIs for MDD management, consider assessing the patient for MDD first, taking a detailed health history, and discussing the risk versus benefits of starting SSRIs for this patient (1, 3).  

What Is the Average Cost for SSRIs? 

Cost for SSRIs can significantly vary depending on the type of SSRI, insurance, dosage, frequency, and other factors. Cost is among leading reasons why many patients cannot maintain their medication regime (4). If cost is a concern for your patient, consider reaching out to your local pharmacies or patient care teams to find cost-effective solutions for your patients.  

What Is Major Depressive Disorder (MDD)? 

Major depressive disorder (MDD) is a mental health condition in which a person has consistent appetite changes, sleep changes, psychomotor changes, decreased interest in activities, negative thoughts, suicidal thoughts, and depressed mood that interfere with a person's quality of life (5). According to the Diagnostic and Statistical Manual of Mental Health Disorders, a patient must have at least five persistent mood related symptoms, including depression or anhedonia (loss of interest in activities once enjoyed), that interferes with a person's quality of life to be formally diagnosed with MDD. Note that MDD does not include a history of manic episodes, and pediatric populations can present with more variable MDD symptoms (5). As an APRN, you can assess for MDD by doing a detailed patient health history or having a patient complete the Patient Health Questionnaire-9 (PHQ-9) - a depression assessment tool (5).

SSRI Pharmacokinetics  

Drug Class SSRIs 

Selective serotonin reuptake inhibitors, known as SSRIs, are a type of pharmacological drug class part of the antidepressant drug class. They can be prescribed at various dosages depending on the patient history, severity of major depressive disorder (MDD), other medication use, and other factors based on patient-centered decision making. Currently, SSRIs that are FDA approved for MDD management include paroxetine, sertraline, citalopram, escitalopram, vilazodone, and fluoxetine. SSRIs can be prescribed for the oral route and are available via capsule, tablet, or liquid suspension/solution. SSRIs can be taken at any time of day. They can be taken with or without food, though vilazodone in particular is recommended with food. SSRIs are often prescribed to be taken once a day, sometimes twice a day, depending on the severity of MDD. Health care provider professional discretion and patient condition should guide therapy (1).  

SSRIs are metabolized by and known to affect the cytochrome P450 system. CYP2D6 inhibitors include escitalopram, citalopram, sertraline, paroxetine, and fluoxetine. Fluoxetine and fluvoxamine are inhibitors of CYP2C19. Fluvoxamine is an inhibitor of CYP1A2. Consider reviewing a patient's medication history and health history prior to prescribing SSRIs (1).   

SSRIs Method of Action 

SSRI method of action has been subject to several studies, especially in the last few years. Serotonin is a neurotransmitter that plays a role in mood and other bodily functions. It can be measured in plasma, blood, urine, and CSF (6). It is important to note that serotonin is rapidly metabolized to 5-hydroxyindoleacetic acid (5-HIAA) (6). SSRIs work by inhibiting the reuptake of serotonin at certain chemical receptors, thereby increasing serotonin activity and concentration (1). SSRIs inhibit the serotonin transporter (SERT) at the presynaptic axon terminal.  

By obstructing the SERT, a higher amount of serotonin (5-hydroxytryptamine or 5HT) remains in synaptic clefts. This higher amount of serotonin can then stimulate postsynaptic receptors for a more extended period (1). While SSRIs can increase serotonin activity, there is some evidence that suggests the possibility of long-term SSRI use reducing serotonin concentration (6). In addition, the clinical response to SSRIs in patients with MDD can take anywhere from a few to several weeks to emerge (7). While some research suggests that there are initial improvements in mood, evidence remains inconclusive as to the exact time SSRIs can take to provide a therapeutic response for patients (7). Also, while research suggests that SSRIs can increase serotonin levels, there is still mixed evidence on the exact method of action for SSRIs (7).  

As a result, it is important to counsel patients that SSRIs can take a few weeks to provide a therapeutic response and to monitor mood and symptoms while taking SSRIs.  

SSRI Side Effects 

Every medication has the possibility of side effects, and SSRIs are no exception. Fortunately, SSRIs are known to have less side effects than other drug classes of antidepressants, such as monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants (TCAs). The most commonly known side effects of SSRIs include weight gain, sleep changes, headache, gastrointestinal issues, drowsiness, orthostatic hypotension, and sexual function changes (1).  

Sleep changes can include an increased desire to sleep, increase in the amount of time sleeping, or insomnia. Gastrointestinal issues can include an upset stomach, nausea, or dry mouth. Mood changes, such as anxiety, are possible side effects as well. Sexual function changes can include erectile dysfunction, libido changes, impaired orgasmic response, and vaginal dryness (1, 8).  

There are more serious possible side effects of SSRIs as well. For instance, SSRIs have the possible side effect of QT prolongation, which if left untreated or undiagnosed, can lead to fatal cardiac arrythmias (1, 8). In particular, the SSRI citalopram has been shown to have more of a risk for QT prolongation compared to other SSRIs. Also, like any other medication that can possibly increase levels of serotonin in the body, there is a possibility of serotonin syndrome as a complication of SSRI use. Possible serotonin syndrome clinical manifestations include increased blood pressure, increased sweating, increased reflex ability, and increased dry eyes (8). Due to the wide varied range of side effects, patient counseling, monitoring, and education is essential when prescribing SSRIs. 

SSRI Black Box Warning  

In 2004, the FDA issued a black box warning for SSRIs and other antidepressant medications due to the possible increased risk of suicidality in pediatric and young adult populations (up to age 25). When considering SSRI use in patients under 25 and knowing MDD is a risk factor for suicidality, having a conversation with the patient about risks versus benefits must be considered. However, in the past several years since the FDA's warning, there is no clear evidence showing a correlation between SSRIs and the increased risk of suicidality (1, 8). Health care provider professional discretion and patient condition should guide therapy. 

SSRI Alternatives 

MDD can be a complex, chronic condition to manage with varying clinical presentation and influence on a patient's quality of life. There are several alternatives to SSRI use, such as: (1, 9) 

  • Other prescription drugs 
    • Serotonin-norepinephrine reuptake inhibitors(SNRIs). Commonly known SNRIs include milnacipran, venlafaxine, desvenlafaxine, duloxetine, and levomilnacipran. 
    • Atypical antidepressants. Commonly known atypical antidepressants include bupropion and mirtazapine. 
    • Tricyclic antidepressants(TCAs). Commonly known TCAs include amitriptyline, desipramine, imipramine, clomipramine, doxepin, and nortriptyline. 
    • Monoamine oxidase inhibitors (MAOIs). Commonly known MAOIs include phenelzine, tranylcypromine, isocarboxazid, and selegiline. 
  • Psychotherapy, such as cognitive behavioral therapy (CBT) or interpersonal therapy 
  • Electroconvulsive therapy (ECT) 
  • Vagus Nerve Stimulation (VNS) 
  • Transcranial Magnetic Stimulation (TMS)

Nursing Considerations 

Nurse’s Role 

What Is the Nurses' Role in SSRI Patient Education and Management? 

Nurses remain the most trusted profession for a reason, and APRNs are often pillars of patient care in several health care settings. Patients turn to nurses for guidance, education, and support. While there is no specific guideline for the nurses' role in SSRI education and management, here are some suggestions to provide quality care for patients interested in or currently taking SSRIs to manage current or suspected major depressive disorder (MDD). 

  1. Take a detailed health history. Often times, mental health symptoms, such as depressive thoughts or anxiety, are often dismissed in health care settings, even in mental health settings. If a patient is complaining of symptoms that could be related to major depressive disorder, inquire more about that complaint. Ask about how long the symptoms have lasted, what treatments have been tried, if these symptoms interfere with their quality of life, and if anything alleviates any of these symptoms. If you feel like a patient's complaint is not being taken seriously by other health care professionals, advocate for that patient to the best of your abilities.  
  2. Review medication history at every encounter. Often times, in busy clinical settings, reviewing health records can be overwhelming. While a vast number of people take SSRIs, many are no longer benefiting from the medication. Ask patients how they are feeling on the medication, if their symptoms are improving, and if there are any changes to medication history.  
  3. Ask about family history. If someone is complaining of symptoms that could be related to MDD, ask if anyone in their immediate family, such as their parent or sibling, experienced similar conditions.   
  4. Be willing to answer questions about mental health and SSRIs. Society can often stigmatize open discussions of prescription medication and mental health. SSRIs are no exception. There are many people who do not know about the benefits and risks of SSRIs, the long-term effects of unmanaged MDD, or possible treatment options. Be willing to be honest with yourself about your comfort level discussing topics and providing education on SSRIs and MDD.  
  5. Communicate the care plan to other staff involved for continuity of care. For several patients, MDD management often involves a team of mental health professionals, nurses, primary care specialists, pharmacies, and more. Ensure that patients' records are up to date for ease in record sharing and continuity of care. 
  6. Stay up to date on continuing education related to SSRIs and mental health conditions, as evidence-based information is always evolving and changing. You can then present your new findings to other health care professionals and educate your patients with the latest information. You can learn more about the latest research on SSRIs and mental health by following updates from evidence-based organizations.  

 

Identifying Major Depressive Disorder 

How can nurses identify if someone has major depressive disorder?  

Unfortunately, it is not possible to look at someone with the naked eye and determine if they have MDD. APRNs can identify and diagnose if someone has MDD by taking a complete health history, listening to patient's concerns, having patients complete the PHQ-9 questionnaire and communicating any concerns to other health care professionals (9). 

 

Patient Education 

What should patients know about SSRIs?  

Patients should know that anyone has the possibility of experiencing side effects of SSRIs, just like any other medication. Patients should be aware that if they notice any changes in their mood, experience any sharp headaches, or feel like something is a concern, they should seek medical care. Due to social stigma associated with mental health and SSRI use, people may be hesitant to seek medical care for fear of being dismissed by health care professionals (1, 6). In addition, side effects (that interfere with the quality of life) are often normalized (1, 6). However, as more research and social movements discuss mental health and SSRI use more openly, there is more space and awareness for SSRI use and mental health.  

Nurses should also teach patients to advocate for their own health in order to avoid progression of MDD and possible unwanted side effects of SSRIs. Here are important tips for patient education in the inpatient or outpatient setting.  

  • Tell the health care provider of any existing medical conditions or concerns (need to identify risk factors) 
  • Tell the health care provider of any existing lifestyle concerns, such as alcohol use, other drug use, sleeping habits, diet, menstrual cycle changes (need to identify lifestyle factors that can influence SSRI use and MDD) 
  • Tell the health care provider if you notice any changes in your mood, behavior, sleep, sexual health (including vaginal dryness or erectile dysfunction), or weight (possible changes that could hint at more chronic side effects of SSRIs) 
  • Tell the health care provider if you have any changes in urinary or bowel habits, such as increased or decreased urination or defecation (potential risk for SSRI malabsorption or possible unwanted side effects) 
  • Tell the nurse of health care provider if you experience any pain that increasingly becomes more severe or interferes with your quality of life 
  • Keep track of your mental health, medication use, and health concerns via an app, diary, or journal (self-monitoring for any changes) 
  • Tell the health care provider right away if you are having thoughts of hurting yourself or others (possible increased risk of suicidality is a possible side effect for SSRI use) 
  • Take all prescribed medications as indicated and ask questions about medications and possible other treatment options, such as non-pharmacological options or surgeries 
  • Tell the health care provider if you notice any changes while taking medications or on other treatments to manage your MDD (potential worsening or improving mental health situation)

Anticoagulant Therapy

Introduction   

Anticoagulants are a class of medications that prevent and treat blood clots, or venous thromboembolism (VTE).  

The Centers for Disease Control and Prevention (CDC) estimates that around 900,000 people in the United States are affected by some form of venous thrombosis every year. Furthermore, the CDC estimates around 60,000 to 100,000 Americans die from some form of venous thromboembolism each year.  

They further state that sudden death is the first symptom that occurs in about 25% of people who have a pulmonary embolism [4]. Thus, healthcare providers must be knowledgeable of the signs and symptoms of venous thromboembolism and the available anticoagulants for prevention and treatment.  

Understanding the different pharmacokinetics of anticoagulant medication is essential during drug selection. This course outlines anticoagulant pharmacology and addresses pharmacokinetics, including mechanism of action, side effects, usage, and contraindications. 

Definitions 

Anticoagulants - medications used to prevent and treat blood clot formation, commonly referred to as “blood thinners” [5]. 

Venous Thromboembolism - a condition where a blood clot forms in a vein, including deep vein thrombosis and pulmonary embolism, and appears during periods of hemostasis [5].

Medications Overview 

Anticoagulant medications are used for the prevention and treatment of venous thromboembolism in both inpatient and outpatient settings.  

The major anticoagulant medication classes include: 

  • Unfractionated Heparin 
  • Low Molecular Weight Heparin 
  • Vitamin K Dependent Antagonists 
  • Direct Oral Anticoagulants 
  • Direct Thrombin Inhibitors 
  • Direct Factor Xa Inhibitors [14] 

Unlike anticoagulants, antiplatelets act on platelet formation. Although commonly mistaken as an anticoagulant, they are not a part of this class [14].  

Depending on the type of anticoagulant, they have other indications for use, such as: 
 

  • Atrial Fibrillation stroke prevention 
  • Left Ventricular Thrombus 
  • Left Ventricular Aneurysm 
  • Prosthetic Heart Valve 
  • Venous Thromboembolism treatment 
  • VTE prevention in people with cancer 
  • Pulmonary Embolism 
  • Pregnancy 
  • Heparin-Induced Thrombocytopenia

Pharmacokinetics 

Unfractionated Heparin 

Unfractionated heparin, also known as heparin, is a medication used to prevent excess blood coagulation. It’s used to prevent and treat thrombotic events like deep vein thrombosis (DVT) and pulmonary embolism (PE).  

Heparin is also used in patients with atrial fibrillation to prevent blood clot formation and during medical procedures, like dialysis, continuous renal replacement therapy, extracorporeal circulation, and heart catheterizations and surgeries. It’s also used for various off-label indications and usually in inpatient settings, such as acute coronary syndrome, percutaneous coronary intervention (PCI), or as a bridge medication when converting to oral anticoagulants [15]. 

Heparin works by binding to an antithrombin that inactivates thrombin and thus, blocks the clotting cascade. More specifically, by inactivating thrombin factor IIa and factor Xa, fibrinogen is not converted to fibrin, and in turn, prevents clot formation [15]. 

Heparin is available via intravenous (IV) and subcutaneous (SQ) forms. Intravenous heparin is infused via continuous infusion until therapeutic levels are achieved, while the SQ form is administered intermittently for VTE prophylaxis. Starting dosages of IV heparin usually begin with a bolus of 80 units per kilogram (kg), and then a continuous infusion rate of 18 units/kg/hour. However, this is dependent on the underlying medical condition being treated and is titrated to achieve therapeutic levels.  

In hospital settings, heparin flushes are available to lock and maintain IV-line patency. Additionally, subcutaneous dosages of heparin are weight-based and dependent on the medical condition [15].  

Common side effects of heparin include: 

  • Bleeding 
  • Thrombocytopenia 
  • Injection site reactions 
  • Hyperkalemia  

[15] 

 

As bleeding is a common side effect, nurses and healthcare providers must monitor patients for evidence of bleeding. Some signs or symptoms of bleeding can include petechiae, bruising, nosebleeds, hematuria, and bright red or dark, tarry stools. Moreover, heparin-induced thrombocytopenia (HIT) usually occurs within five days of initiating heparin therapy, causing serious adverse effects, like myocardial infarction, stroke, DVT, PE, and even death [15]. 

Before ordering this medication, healthcare providers should be aware of this anticoagulant’s contraindications. Heparin is contraindicated in individuals who have a platelet count of less than 100,000/mm or they have an active, uncontrolled bleed except if they have disseminated intravascular coagulation (DIC). It should also be avoided in patients with a history of HIT or who cannot have routine blood monitoring of heparin therapeutic levels.  

Monitoring the patient’s hemoglobin, hematocrit, and vital signs is also essential to detecting a possible hemorrhage [15]. 

As heparin affects clotting time, healthcare providers must order therapeutic monitoring for activated partial thromboplastin time (aPTT) and activated clotting time (ACT). Prior to patients being initiated on a heparin infusion, a baseline aPTT level is drawn and then subsequently monitored every 6 hours until a therapeutic aPTT level is achieved. After there are two or more aPTT therapeutic results, then an aPTT is drawn every 24 hours.  

The therapeutic range of heparin is typically 1.5 to 2 times the normal range, and titration algorithms are dependent on the healthcare facility’s protocols. ACT monitoring is less specific than aPTT and is typically reserved for PCI or cardiac bypass [15].

Low Molecular Weight Heparin 

Another medication used to prevent excess blood coagulation is low molecular weight heparin (LMWH). This medication is used to prevent venous thromboembolic disease in hospitalized patients and is also used to treat DVT and PE. Low molecular weight heparin is also approved for use and treatment of medical conditions such as ST-elevation myocardial infarction (STEMI), unstable angina, and extracorporeal clot prevention.  

Common names of LMWH include enoxaparin and dalteparin [13]. 

Low molecular weight heparin’s mechanism of action works on the body’s clotting cascade by activating antithrombin III. Once antithrombin III is activated, it binds to factor Xa, which inhibits thrombin activation. Therefore, clot formation is prevented since fibrinogen is not converted to fibrin. This medication’s mechanism of action slightly differs from heparin, as LMWH inhibits factor Xa only, while heparin acts on factor IIa and factor Xa [13]. 

Low molecular weight heparin is available via subcutaneous injection. Dosages of this medication are typically calculated by body weight and are dependent on whether it’s being used for prevention or treatment. LMWH is typically administered once or twice daily and is safe to administer during pregnancy.  

Some adverse effects of LMWH include:  

  • Bleeding 
  • Heparin-induced Thrombocytopenia 
  • Injection site reactions 
  • Osteoporosis [13]. 

Some other side effects are spontaneous fracture, hyperaldosteronism, and hypersensitivity reactions. Before prescribing this medication, healthcare providers must be knowledgeable of LMWH contraindications. It’s contraindicated in patients with hemorrhagic disorders, peptic ulcer disease, cerebral hemorrhage, trauma, and recent eye or nervous system surgeries.  

Additionally, healthcare providers should caution when prescribing LMWH to patients with chronic kidney disease, as it increases the risk of accumulation in their system. Lower doses may be required for these individuals. A benefit of low molecular weight heparin when compared to unfractionated heparin is that the patient’s aPTT blood levels do not need to be monitored [13].

Vitamin K Dependent Antagonists

Vitamin K antagonists (VKAs) are a class of anticoagulant medications used in the prevention and treatment of blood clots. Warfarin is a commonly prescribed VKA and other less common VKAs are acenocoumarol, fluindione, and phenprocoumon [7].  

Warfarin is approved for the treatment and prevention of pulmonary embolism, venous thrombosis, and thromboembolic complications of heart valve replacement and atrial fibrillation. It’s also used to reduce mortality risk after a myocardial infarction or stroke. Prevention of transient ischemic attack and stroke are additional off-label indications [11]. 

Vitamin K antagonists act by inhibiting the liver’s vitamin K epoxide reductase complex 1 (VKORC1). This reduces the amount of vitamin K reserves and therefore reduces the production of the body’s clotting factors that require vitamin K. Some clotting factors that are reduced include factors II, VII, IX, and X [7]. 

Vitamin K antagonists are available in oral form and are typically taken once daily in the afternoon or evening. Warfarin is rapidly absorbed, and onset of action is about 24 to 72 hours. The medication’s therapeutic effects aren’t normally seen until five to seven days after taking the medication. The typical starting dosage is 5 mg but might be less (2.5 mg) in patients who are elderly or who have liver disease [11].  

Some common side effects of this class of medications include: 

  • Bleeding or bruising 
  • Nausea 
  • Vomiting 
  • Abdominal pain 
  • Altered sense of taste [11]. 

As VKAs alter the body’s ability to clot, it can cause more serious adverse effects, such as: 

  • Significant bleeding or hemorrhage 
  • Purple toe syndrome 
  • Warfarin-induced skin necrosis 
  • Calciphylaxis [11]. 

 

Warfarin and other VKAs have several contraindications such as gastrointestinal bleeding, cerebral aneurysm, dissecting aortic aneurysm, or other hemorrhagic conditions. Additionally, if the patient has had a recent nervous system, eye, or trauma surgery, then this medication should not be prescribed. Threatened abortion, malignant hypertension, and regional or lumbar anesthesia blocks are contraindications as well [11]. 

When prescribing VKAs, healthcare providers must order therapeutic monitoring and assess the patient’s prothrombin (PT) or international normalized ratio (INR). INR is usually the preferred method where a baseline level is initially drawn, and then subsequent levels are drawn within a week. The therapeutic range is dependent on the underlying medication condition, where the goal can range from an INR of 2 to 3 for most patients or from 2.5 to 3 for patients with a mechanical mitral valve.  

Once the patient has reached their therapeutic goal, levels are typically drawn every four weeks unless there have been changes in their medications. Additionally, patients who take VKAs should have their hemoglobin and hematocrit levels and liver and kidney function checked at least every 6 months [11].

Direct Oral Anticoagulants 

Direct oral anticoagulants (DOACs) are a class of anticoagulant medications mainly used to prevent thrombosis formation. There are two main classes of DOACs, which include direction thrombin inhibitors and direct factor Xa inhibitors [6]. 

 

Direct Thrombin Inhibitors 

Direct thrombin inhibitors (DTIs) are used to treat and prevent thrombosis in patients with heparin-induced thrombocytopenia, acute coronary syndrome, or during percutaneous coronary intervention. Common names of direct thrombin inhibitors include argatroban, bivalirudin, fondaparinux, and dabigatran [9]. Additional off label uses may include anticoagulation during dialysis or renal replacement therapy, and it can be used as an alternative anticoagulant for patients who are resistant to heparin [10]. 

Direct thrombin inhibitors block coagulation activities that are involved in fibrin clot formation. There are two types of direct thrombin inhibitors, which are univalent DTIs that act by binding to the active site of thrombin, and bivalent DTIs that bind to two sites, the active thrombin site and exosite I.  

As the thrombin pathways are blocked and cleavage of fibrinogen to fibrin is prevented, this ultimately inhibits clot formation and coagulation [9]. Some DTIs, like argatroban, are metabolized primarily via the cytochrome P450 enzyme [10]. 

This class of anticoagulant medications is typically available in intravenous form. However, it is also available in oral form, but dabigatran is the only available oral form. Starting dosages for DTIs depend on the medical condition being treated [9].  

Some side effects of DTIs may include: 

  • Bleeding 
  • Gastrointestinal symptoms and bleeding 
  • Hypotension 
  • Dyspnea 
  • Fever 
  • Sepsis  

[10] 

When DTIs are used during PCI, some potential side effects are back pain, nausea, chest pain, and headache. Contraindications include increased bleeding, a history of medication hypersensitivity, lumbar puncture, and spinal anesthesia [10]. 

As most patients who are treated with DTIs have HIT, aPTT monitoring is common and the goal is 1.5 to 3 times the patient’s baseline. For patients who undergo PCI, ACT is used, and levels are obtained according to the hospital’s protocol or policy [10]. 

 

Direct Factor Xa Inhibitors 

Direct factor Xa inhibitors are used to prevent and treat several blood clotting disorders. Examples of direct factor Xa inhibitors include apixaban, rivaroxaban, and edoxaban and they are only available in oral form [9].  

These medications are often used to reduce the risk of stroke in patients with atrial fibrillation or other cardiac arrhythmias. Direct Xa inhibitors are also used to prevent and treat conditions like DVT or PE [1]. Rivaroxaban is approved for secondary prevention and adjunct therapy after acute coronary syndrome and peripheral artery disease [12]. 

Direct factor Xa inhibitors directly bind to factor Xa, preventing it from cleaving prothrombin to thrombin. This results in blocking the propagation phase of the coagulation cascade [9]. It is metabolized via the liver and by the CYP3A4/5 and CYP2J2 mechanisms [12]. 

Starting dosages of direct factor Xa inhibitors depend on the underlying medical condition. Rivaroxaban usually is started at 20mg daily for atrial fibrillation stroke prevention or 10mg daily for VTE prevention [12].  

Some side effects of direct factor Xa inhibitors may include: 

  • Dizziness 
  • Hemorrhage 
  • Abdominal Pain  
  • Pruritis 
  • Nausea  

[1] [12] 

 

Direct factor Xa inhibitors have several drug interactions and thus, the healthcare provider must review any potential interactions before initiating this medication. Common drugs that have potential interactions are aspirin, ketoconazole, phenytoin, rifampin, and carbamazepine [1].  

They are also contraindicated in patients with hepatic and renal impairment, antiphospholipid syndrome, and increased bleeding risk. Most have black box warnings of increased risk of thrombotic adverse events and spinal or epidural hematoma. They should also be avoided in patients who are pregnant or breastfeeding [12]. 

Although this class of medications does not require routine blood monitoring, the healthcare provider should consider obtaining baseline aPTT, PT, and kidney and liver function.  

If the patient is scheduled for surgery with a moderately high risk of bleeding, direct factor Xa inhibitors should be held for at least 48 hours before the procedure [1].

Considerations for Prescribers 

This section reviews potential considerations when prescribing anticoagulants. 

When prescribing anticoagulant medications, healthcare providers must consider and review several factors. First, the route and dosage are typically determined by the setting, inpatient versus outpatient, if it’s being used for prevention or treatment, and the underlying medical condition.  

Additionally, healthcare providers should strive to follow current guidelines, approved uses, and hospital protocols when initiating or adjusting these medications. Healthcare providers must review the patient’s medical history, baseline lab values, contraindications, and recommended therapeutic medication range as discussed above.  

Low molecular weight heparin is often considered safe during pregnancy [13]. Certain anticoagulants, especially warfarin, should be avoided in patients who are elderly, prone to falls, or have reduced kidney function [11]. Oftentimes, anticoagulants are combined with antiplatelet medications to produce better therapeutic results in certain medical conditions [8]. 

Healthcare providers should also review the potential common and adverse side effects of anticoagulants with patients. Additionally, as bleeding is a serious adverse effect, they should review potential signs of bleeding, such as dizziness, uncontrolled bleeding to the skin, blood in the stool or urine, and other symptoms [15]. Patients should be instructed to seek immediate medical treatment if they experience any of these symptoms, fall at home, or have another traumatic injury.  

In addition, they should be instructed on how to control bleeding when cuts occur to the skin [11]. A common side effect of LMWH is pain and bruising around the injection site. Therefore, patients should understand the importance of rotating injection sites and if side effects become a concern, then an oral alternative should be considered [13]. 

As periodic blood monitoring is required for many anticoagulants, such as INR, PT, or aPPT, the healthcare provider must review the importance of completing these labs and coming to their scheduled visits [15, 11]. If the patient is non-compliant with laboratory monitoring, then the healthcare provider should consider other alternatives, such are direct oral anticoagulants that do not require routine bloodwork or DTIs that have a wider therapeutic range [6] [9]. 

In addition, the healthcare provider must be knowledgeable about the potential drug interactions for each medication and dietary concern. For example, patients on vitamin K antagonists should reduce their intake of foods high in vitamin K since it counteracts the therapeutic effects of the medication. They should avoid foods rich in vitamin K, such as spinach, kale, and broccoli [7]. Co-administration of other anticoagulants, aspirin, and non-steroidal anti-inflammatory medications also increases bleeding risk [11]. 

Most anticoagulant medications can potentially cause toxicity and patients should seek emergency medical treatment. Therefore, healthcare providers must be aware of the signs and symptoms of toxicity and the reversal agent, or antidote, for each medication.  

Protamine sulfate is the reversal agent for heparin and low molecular weight heparin. Protamine sulfate is administered via IV push and if administered too rapidly can lead to pulmonary edema, vasoconstriction, and pulmonary hypertension [15]. Vitamin K is the antidote for vitamin K antagonists [11]. Andexanet alfa is the reversal agent for direct factor Xa inhibitors and idarucizumab is approved for the reversal of dabigatran specifically [12].

Upcoming Research 

This section reviews upcoming research and medications for anticoagulant treatment. 

There have been many new anticoagulant medications introduced over the past several years and research continues to evolve for this type of medication. More recently, a newer class of anticoagulant medications called anti-factor XI and Xia inhibitors, affect the factor XI pathway for clot formation. However, it’s still being researched and there are ongoing clinical trials [3].  

Moreover, in November 2023, the American Heart Association released promising information about abelacimab, a monoclonal antibody that acts as a factor XI inhibitor, which has been shown to reduce stroke risk in patients with atrial fibrillation. The same report stated that bleeding risk was reduced by more than 60% while taking this medication [2].  

Potential factor VII and VIII inhibitors are also being researched [16].

Conclusion

Anticoagulants are typically indicated for the prevention and treatment of blood clotting conditions, including deep vein thrombosis and pulmonary embolism. However, they have several additional approved and off-label uses. Healthcare providers should understand the pharmacokinetics, potential side effects, and contraindications when selecting an anticoagulant. They should also follow current clinical guidelines and their facility’s protocols for a more evidence-based approach.

SNRIs for Depression

Introduction   

Depression can significantly interfere with daily activities and diminish quality of life among patients who experience it. Major depressive disorder (MDD) is one of the leading causes of the burden for worldwide diseases (5). At the present stage, the first-line treatment of MDD is selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). Research has found that SNRIs showed faster antidepressant effects than SSRIs (5).  

The serotonin norepinephrine reuptake inhibitors (SNRIs) are a family of antidepressants that inhibit the reuptake of both serotonin and norepinephrine; however, it is important to recognize the differences among each specific drug in this class. In this course, we will examine pharmacological properties, clinical indications, mechanism of action, metabolism and excretion, dosing schedules, side effects, and warnings of each SNRI currently approved by the United States Food and Drug Administration (FDA) for the treatment of depression.

Forms and Symptoms of Depression 

Depression can have crippling effects. Research suggests that genetic, biological, environmental, and psychological factors play a role in depression (7). Depression can be present with other comorbidities, such as mental disorders, diabetes, cancer, heart disease, and chronic pain. Depression can make these conditions worse, and vice versa. Certain medications have been shown to increase depressive symptoms.  

Common forms of depression are: (7) 

  • Major depression - which includes symptoms of depression most of the time for at least two weeks that regularly interfere with work, sleep, eating, and quality of life. 
  • Persistent depressive disorder (dysthymia), which often includes less severe symptoms of depression that last much longer, typically for at least two years. 
  • Perinatal depression - occurs when a woman experiences major depression during pregnancy or after delivery (postpartum depression). 
  • Seasonal affective disorder – impacted by change in seasons, typically starting in late fall and early winter and improving during spring and summer. 
  • Depression with symptoms of psychosis - a severe form of depression in which the patient experiences psychosis symptoms, such as delusions or hallucinations 

Common symptoms of depression include: 

  • Persistent sad, anxious, or “empty” mood 
  • Feelings of hopelessness 
  • Irritability, frustration‚ or restlessness 
  • Feelings of guilt, worthlessness, or helplessness 
  • Loss of interest or pleasure in hobbies or activities once enjoyed 
  • Fatigue or lack of energy 
  • Aches, musculoskeletal pain, or headaches without injury or obvious causation, and do not improve with medication. 
  • Gastrointestinal issues 
  • Difficulty concentrating, remembering, or making decisions 
  • Poor sleeping patterns 
  • Changes in appetite  
  • Suicide attempts or thoughts of death or suicide

    Pharmacokinetics of SNRIs 

    The major mechanism of action of SNRIs is the inhibition of presynaptic neuronal uptake of 5-HT (serotonin) and norepinephrine after release from the synaptic cleft (3). Blocking the reuptake prolongs the presence of monoamines in the synaptic cleft within the central nervous system (CNS). This causes an increase in postsynaptic receptor stimulation and additional post synaptic neuronal transmission (3).  

     

    Serotonin 

    Serotonin, or 5-hydroxytryptamine (5-HT), is a neurotransmitter that has an important role in regulating various activities, including behavior, mood, memory, and gastrointestinal homeostasis (1). It is often referred to as the “feel good hormone” and delivers messages between brain cells, contributing to well-being, mood, appetite, social behavior, as well as helping to regulate the body’s sleep-wake cycle.  

    Serotonin is synthesized in the raphe nuclei of the brainstem and the enterochromaffin cells of the intestinal mucosa (1). Serotonin is a primary treatment target for major depressive disorder (MDD), post-traumatic stress disorder (PTSD), obsessive-compulsive disorder (OCD), and anxiety disorders. 

     

    Norepinephrine 

    Norepinephrine, also known as noradrenaline, is a neurotransmitter in the brain that plays an essential role in the regulation of arousal, attention, cognitive function, and stress reactions. It also functions as a hormone peripherally as part of the sympathetic nervous system in the “fight or flight” response. 

    During states of stress or anxiety, norepinephrine and epinephrine are released and bind to adrenergic receptors throughout the body which exert effects such as dilating pupils and bronchioles, increasing heart rate and constricting blood vessels, increasing renin secretion from the kidneys, and inhibiting peristalsis. 

    It works closely with dopamine and serotonin systems and is thought to help mobilize the brain for action, increasing alertness, focus, and the retrieval of memory (4). 

    The increased availability of serotonin and norepinephrine in the nerve synapse means that information can be transmitted easier from one nerve to another.  

    There are currently five SNRIs approved by the FDA for use in the U.S.: 

    • Venlafaxine (Effexor XR) 
    • Duloxetine (Cymbalta, Irenka) 
    • Desvenlafaxine (Pristiq, Khedezla)
    • Levomilnacipran (Fetzima)
    • Milnacipran (Savella)
      • Milnacipran (Savella TM) is not approved by the FDA to treat depression, but rather only fibromyalgia. For this reason, this course will not review this SNRI.

     As mentioned, all SNRIs regulate serotonin and norepinephrine, but there are subtle differences in how much absorption they prevent and the side effects of each type.

      Venlafaxine 

      Venlafaxine (Effexor ™) is approved by the FDA and was the first SNRI approved in the U.S. It is available in an extended-release formula and works by regulating levels of serotonin and norepinephrine. 

       

      Uses 

      • Major depressive disorder 
      • Generalized anxiety disorder
      • Social anxiety disorder
      • Panic disorder  

         

        Mechanism of Action 

        Venlafaxine increases serotonin, norepinephrine, and dopamine in the brain by blocking transport proteins and preventing their reuptake at the presynaptic terminal (10). This action leads to more neurotransmitters available at the synapse, which ultimately increases the stimulation of postsynaptic receptors.  

        Venlafaxine is a bicyclic phenylethylamine compound; it is a more potent inhibitor of serotonin reuptake than norepinephrine reuptake (8). Venlafaxine acts as a selective serotonin reuptake inhibitor at 75 mg, but when a higher dose is given, such as 225 mg/day, it has significant effects on the norepinephrine transporter as well (10). Venlafaxine does not have MAO-inhibitory properties. 

         

        Pharmacodynamics 

        The pharmacodynamics of venlafaxine is as follows: (9) 

        Absorption: 92-100% absorbed after oral administration. 

        Distribution: Extensive distribution into body tissues. 

        Metabolism and Excretion: Extensively metabolized in first pass through the liver. 5% of venlafaxine is excreted unchanged in urine; 30% of the active metabolite is excreted in urine. 

        Half-life:  3-5 hr.; ODV: 9-11 hr.  

         

        Contraindications 

        • Hypersensitivity 
        • Precaution advised for use in patients with:  
          • Cardiovascular disease 
          • Hepatic or renal impairment  
          • History of seizures or neurologic impairment 
          • History of mania 
          • History of drug abuse 
          • Angle-closure glaucoma 

        Obstetrics (OB): Use during pregnancy only if risks are closely examined. There is a potential for discontinuation syndrome or toxicity in the neonate when venlafaxine is taken during the 3rd trimester (9). Venlafaxine is a category C pregnancy drug and can potentially pass into breast milk (8). 

        Venlafaxine is contraindicated if it causes worsening suicidal ideation, depression, anxiety, and psychosis. Precaution is needed for patients with heart failure patients, hyperthyroidism, and those with recent myocardial infarctions, as it can raise blood pressure and increase heart rate. Venlafaxine raises the risk of seizures, and prescribers should avoid the drug in patients with a seizure disorder (8).  

         

        Adverse Reactions / Side Effects 

        Adverse reactions / side effects of venlafaxine include: (10) 

        CV: Chest pain, hypertension, palpitations, tachycardia. 

        Neuro: Abnormal dreams, anxiety, dizziness, headache, insomnia, nervousness, paresthesia. 

        Dermatology: ecchymoses, itching, photosensitivity, skin rash. 

        EENT: rhinitis, visual disturbances. 

        GI: abdominal pain, altered taste, anorexia, constipation, diarrhea, dry mouth, dyspepsia, nausea, vomiting, weight loss. 

        GU: Decreased libido, erectile dysfunction, urinary frequency, urinary retention. 

        Hematological: Bleeding. 

        Serotonin syndrome – a condition of building up high levels of serotonin in the body due to medication use. Although rare, serotonin syndrome is a very serious condition that has a high mortality rate (5). Signs of serotonin syndrome include tachycardia, sialorrhea (excessive saliva production), hyperactive bowel sounds, mydriasis (sustained dilated pupils), hyperthermia, and diaphoresis (6). This condition is caused by combining monoamine oxidase inhibitors, tricyclic antidepressants, triptans, additional serotonin receptor modulators, or over-the-counter drugs such as St. John's Wort (6). 

        If a clinician is suspecting serotonin syndrome, the Sternbach and Hunter criteria can be useful to help arrive at a definitive diagnosis.  

         

        Drug-Drug Interactions 

        • Concurrent use with MAO inhibitors or serotonergic neurotransmitter systems, including tricyclic antidepressants, fentanyl, buspirone, tramadol, amphetamines, and triptans, may increase the risk of serotonin syndrome (9).
        • Concurrent use of NSAIDs, aspirin, warfarin or other drugs that affect coagulation may increase the risk of bleeding. 
        • Concurrent use of other medications that may increase risk of hypertension.
        • Concurrent use with alcohol may cause a rapid release of drug and should be avoided.
        • Monitor closely for any changes in behavior that could indicate the emergence or worsening of suicidal thoughts or behavior or depression. 

           

          Route and Dosage in Depression 

          PO (Adults): Tablets: 75 mg/day in 2-3 divided doses; may increase by up to 75 mg per day every 4 days, up to 225 mg/day. Do not exceed 375 mg per day in 3 divided doses.  

          Extended-release capsules: 75 mg once daily (some patients may be started at 37.5 mg once daily) for 4-7 days; may increase by up to 75 mg/day at intervals for no less than 4 days (not to exceed 225 mg/day). 

           

          ALERT: US Boxed Warning 

          Antidepressants increased the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders (10). Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults older than 24 years old (10). 

          Venlafaxine is not approved for use in pediatric patients.

          Duloxetine  

          Duloxetine (Cymbalta ™) has the most FDA-approved uses of any SNRI, and, unlike Venlafaxine, is proven to be effective in the treatment of other conditions, such as neuropathy, fibromyalgia, and osteoarthritis (9).  

           

          Drug Class 

          Selective Serotonin/Norepinephrine Reuptake Inhibitors 

           

          Uses 

          Duloxetine is used for the following conditions: (9) 

          • Major depressive disorder
          • Diabetic peripheral neuropathic pain
          • Generalized anxiety disorder
          • Chronic musculoskeletal pain (including chronic lower back pain and chronic pain from osteoarthritis)
          • Fibromyalgia

           

          Mechanism of Action 

          Duloxetine inhibits serotonin and norepinephrine reuptake, and also enhances dopamine levels within the prefrontal cortex. This increase in dopamine levels involve the inhibition of norepinephrine transporters, which are particularly attracted to dopamine, making it effective in transporting dopamine and norepinephrine (2). Essentially, inhibition of norepinephrine transporters can cause an increase in dopamine.  

          The secondary mechanisms of action, in increasing dopamine, is helpful in pain reduction. This occurs due to increased activity of noradrenergic and serotonergic neurons in the descending spinal pathway on the dorsal horn and suppression of excessive input from reaching the brain (2). The perception of pain can be reduced as these signals are interrupted. 

           

          Pharmacokinetics 

          Absorption: Well-absorbed following oral administration. 

          Distribution: Unknown.

          Desvenlafaxine  

          Desvenlafaxine (Pristiq ™) received approval from the FDA in 2008. The drug is similar to Venlafaxine structurally and 10 times more potent in inhibiting serotonin reabsorbing than norepinephrine (6). It has been observed weakly blocking dopamine reuptake, similar to Venlafaxine and Duloxetine. 

           

          Uses 

          Desvenlafaxine is an antidepressant that is an FDA-approved drug to treat major depressive disorder in adults. For healthy women who have contraindications to estrogen, desvenlafaxine has an off-label use to treat hot flashes during menopause (6). 

           

          Mechanisms of Actions 

          Desvenlafaxine is the primary active metabolite of venlafaxine. Therefore, the two agents are structurally similar in that they both contain two chemical rings that are not next to each other. In vitro studies have shown that desvenlafaxine is ten times more selective for serotonin than for norepinephrine, making it similar to the drug duloxetine (6).  

           

          Pharmacokinetics 

          Absorption: 80% absorbed following oral administration. 

          Distribution: Widely distributed to tissues. 

          Metabolism and Excretion: 55% metabolized by the liver, 45% excreted unchanged in urine.

          • Should not be used concurrently with venlafaxine. 

          Use cautiously in: 

          • Untreated cerebrovascular or cardiovascular disease, including untreated hypertension (control BP before initiating therapy). 
          • Bipolar disorder (may activate mania/hypomania). 
          • Moderate or severe renal impairment. 
          • History of seizures or neurologic impairment. 
          • Moderate or severe hepatic impairment. 
          • Angle-closure glaucoma. 

          OB: Safety is not established in pregnancy. Desvenlafaxine is excreted into breast milk, with one study reporting that peak levels are 3.3 hours after a dose (6). 

           

          Adverse Reactions / Side Effects 

          There is a broad range of general adverse effects that patients have reported with desvenlafaxine. A study comparing desvenlafaxine to a placebo in treating major depressive disorder in adolescents noted the most common side effects to be abdominal pain, decreased appetite, headache, and nausea (6).  

          Less common side effects were diarrhea, dizziness, and cough.  

          Abruptly stopping the use of desvenlafaxine can cause irritability, nausea, and headaches (6). Gradually tapering the medication is recommended to avoid such side effects. 

           

          Drug-Drug Interactions 

          • The concurrent use of all SNRIs and MAO inhibitors may result in serious and potentially fatal reactions (it may increase the risk of serotonin syndrome) (9). A period of at least two weeks is recommended between stopping MAO inhibitors and initiating venlafaxine (9). 
          • Concurrent use of NSAIDs, aspirin, warfarin or other drugs that affect coagulation may increase the risk of bleeding.

          Levomilnacipran  

          Levomilnacipran (Fetzima ™) is the most recent medication approved for treating major depression.  

          Levomilnacipran is different from other SNRIs because it has greater inhibition of norepinephrine than serotonin; essentially, it has twice the potency of norepinephrine reuptake inhibition compared to serotonin (3). The more recent FDA approval and relatively lower number of prescriptions may be contributing factors to an overall low volume of research and evidence on this drug.  

          Levomilnacipran has a one-a-day extended-release form, which makes it easier for patients to stick to its regimen. The drug has no effect on dopamine and affects reuptake inhibition of serotonin and norepinephrine steadily at any dose (3). 

           

          Uses 

          • Major Depressive Disorder 

           

          Mechanisms of Actions 

          Levomilnacipran enhances the amount of serotonin (5-HT) and norepinephrine (NE) activity in the central nervous system byinhibition of reuptake at 5-HT and NE transporters (9). Levomilnacipran has shown to be a more potent inhibitor of NE versus 5-HT transporter (9). 

           

          Pharmacokinetics 

          Absorption: Well-absorbed (92%) following oral administration. 

          Metabolism and Excretion: Primarily metabolized in the liver via the CYP3A4 isoenzyme. 58% eliminated unchanged in urine; 42% metabolized; metabolites are renally eliminated.

          Nursing Considerations 

          It is vital to recognize how each patient is unique and different in their journey of depression treatment. Nurses play a key role in assessing and providing advocacy for these patients.  

           The following are important nursing considerations: 

          • Thorough and focused mental status assessment 
            • Assess level of consciousness and orientation, appearance and general behavior, speech, motor activity, affect and mood, thought and perception, attitude and insight, and cognitive abilities. 
          • Assess status and mood changes.  
          • Assess suicidal tendencies, especially in early beginning of SNRI (9). 
          • Monitor BP before and periodically during therapy. Sustained hypertension may be dose-related; decrease dose or discontinue therapy if this occurs. 
          • Assess for serotonin syndrome. 
          • Provide patient education on medication use, dosage, and side effects. Provide patient education on support and resources available.

          Monitor CBC with differential and platelet count periodically during SNRI therapy. These medications can cause anemia, leukocytosis, leukopenia, thrombocytopenia, basophilia, and eosinophilia (9). 

          May cause an increase in serum alkaline phosphatase, bilirubin, AST, ALT, BUN, and creatinine, and serum cholesterol. 

          SNRIs can also cause electrolyte abnormalities (hyperglycemia or hypoglycemia, hyperkalemia or hypokalemia, hyperuricemia, hyperphosphatemia or hypophosphatemia, and hyponatremia).

          Conclusion

          SNRIs are an effective method of treatment for those suffering from depression. The effectiveness of SNRIs is dependent on a variety of factors like dosage and time spent in the body. Although the mechanisms of actions and makeup of SNRIs are consistent, each drug has differences on how much reuptake they prevent and the side effects of each type. Prescribers must be aware of these differences, the uses, mechanisms of action, side effects, and warnings.

          Corticosteroid Therapy

          Introduction   

          When many people hear of steroids, they may think of athletes. However, the steroids that some athletes misuse to enhance their strength and training abilities are not the same as those administered for allergic reactions and some inflammatory conditions. The steroids used by some athletes are called anabolic steroids. The steroids used for the treatment of disease are called corticosteroids.  

          Steroids are hormones naturally produced in the body (made from cholesterol) to regulate the function of various bodily systems [2]. Some steroid hormones are produced by the adrenal glands of the endocrine system (a set of two glands that rest atop the kidneys). The adrenal glands produce the hormone types: glucocorticoids, mineralocorticoids, and adrenal androgens [2]. Corticosteroid medication mimics glucocorticoids, more specifically a glucocorticoid called “cortisol.” 

          The Immune System 

          Corticosteroids are well-known for increasing a patient’s risk for infection. This is due to the medication’s effect on the immune system, particularly its anti-inflammatory properties. It is important to have a clear understanding of how the immune system works as well as the inflammatory process that takes place when a foreign pathogen enters the body. 

           

          How Does the Immune System Work? 

          In a typical immune system the immune system is triggered by an antigen – a marker in the body that alerts cells of the immune system that there’s a foreign invader present, like a pathogen or foreign object. Subsequently, a series of events follows. Like in a war, the body rounds up the first line of defense soldiers to fight the pathogen.  

          These include [11]: 

          • Proteins (called “the inflammasome”) to active inflammatory responses. 
          • Macrophages to engulf and digest pathogens. 
          • Neutrophils to help kill pathogens and rid of the leftover debris. 
          • Endothelial cells to help rid of the dead pathogens/debris. 

          The influx of these cells to the site of injury or infection is the beginning of inflammation.  

           

          What is Inflammation? 

          Inflammation is more than just “swelling.” Inflammation is a process in which a cascade of events occurs to help the immune system fight against pathogens and foreign bodies. The inflammatory process encompasses a variety of signs/symptoms including redness, warmth, swelling, and drainage [11].  

          For example, when a person sustains a traumatic injury to the skin causing an open wound, the accompanying redness (or erythema) is caused by a rush of red blood cells through the site [5]. The dilation of the blood vessels is what causes this “rush” of cells. The increased blood flow also causes the localized warmth that typically occurs. Blood vessel dilation is responsible for the associated swelling as well. The pus that forms is a combination of fluid, dead immune/pathogen cells, and debris from the fight, essentially, the “casualties at war” that must be removed from the body [5]. 

          As with fever, inflammation aids in the fight against pathogens and therefore should not be inhibited unless it is likely to be damaging or fatal in and of itself. [11]. This inflammatory process is acute in nature, and typically goes away on its own or with the help of medication. While acute inflammation from a normal immune response is natural and beneficial, chronic inflammation is harmful and can lead to permanent damage of tissues and body systems.  

          Chronic inflammation can be seen in conditions including inflammatory bowel disease, cancer, heart disease, and autoimmune disorders like rheumatoid arthritis, multiple sclerosis, and systemic lupus erythematosus [11]. Chronic inflammation is typically caused by an overactive immune system or autoimmune disease (when the immune system mistakenly attacks normal tissues). In cases like these, inhibiting the inflammatory process by suppressing the immune system is most beneficial. This is where corticosteroids come into play.

          Corticosteroids: The Basics 

          Corticosteroids are a group of steroidal therapy medications that are often the go-to for reducing inflammation in the body. Once referred to as “a miracle drug,” these medications are helpful in the treatment of acute and chronic inflammatory conditions and autoimmune diseases.  

          Corticosteroids are also useful in emergency situations, for example during asthma attacks or allergic reactions – when the inflammation is life-threatening. Corticosteroids are synthetically formulated to mimic the hormone cortisol. 

           

          What is Cortisol? 

          As mentioned earlier, the adrenal glands of the endocrine system produce three different types of steroid hormones, one of which is glucocorticoids. Cortisol is a major glucocorticoid hormone.  

          There are two major structures of the adrenal glands – the outer layer (cortex) and inner portion (medulla) – each producing its own hormones. The outer layer (cortex) produces cortisol, hence the name “corticosteroid” [6].  

          Cortisol levels in the body rise when a person is stressed [2]. This hormone helps to regulate metabolism, growth, reproduction, and the immune system [2]. Cortisol also aids in cardiovascular function by making blood vessels more sensitive to natural vasoconstrictors in the body (like adrenaline) [2].  

           

          How Do Corticosteroids Work? 

          Corticosteroids work by suppressing the immune system which in turn reduces inflammation. In patients with an overactive immune system or acute flareups from a triggering agent, the inflammation can cause troubling symptoms, become prolonged, and spread to other areas within the body. If left untreated, inflammation can lead to tissue scarring (or damage to affected structures) and loss of bodily functions [11]. 

          The challenge with administering corticosteroids to suppress an overactive immune system is balancing the benefits of inflammatory symptom relief and the risks of infection due to the resulting underactivity of the immune system. In this case, clinicians are encouraged to start with the lowest therapeutic dose possible, carefully monitor its use in patients with infections, and ensure that the benefits exceed the risks [6]. 

          Corticosteroids also stop the body from producing its own natural cortisol. In a sense, a course of corticosteroids gives the adrenal glands a break. In a short course of corticosteroids, once the medication is discontinued, the adrenal glands can start back releasing cortisol. However, the adrenal glands do not resume releasing cortisol right away and need time to start working again.  

          This is why corticosteroids (oral and parenteral forms) should not be stopped abruptly when taken for more than about two weeks [6]. If stopped abruptly, patients may develop adrenal insufficiency during this period, which can be life-threatening.

          Corticosteroid Pharmacology 

          Common corticosteroid formulations include intravenous (IV), intramuscular (IM), intra-articular (injected directly into a joint), oral, inhaled, intranasal (nasal spray), topical, ophthalmic (eye drops), and otic (ear canal). The increased risk of infection is most associated with systemic formulations (oral and parenteral).  

          The following sections will cover the pharmacology of systemic corticosteroids, including indications, mechanisms of action, pharmacokinetics, precautions, adverse effects, drug interactions, and warnings [7]. 

           

          Indications 

          Corticosteroids are useful in the treatment of many medical conditions. Some indications for corticosteroids among adults include the following diseases, conditions, and situations (maybe drug- or route-specific) [6][7]. 

           

          Allergic Reactions 

          Corticosteroids are well-known for treating mild to severe allergic reactions. These include anaphylaxis, angioedema, and laryngeal edema (non-infectious). Others include hypersensitivity reactions to medications or food, severe seasonal allergies (like allergic rhinitis), contact dermatitis (or rash), and itching. 

           

          Autoimmune Diseases 

          Corticosteroids are used to treat autoimmune disorders including systemic lupus erythematosus, Crohn’s disease, rheumatoid arthritis, and plaque psoriasis. Others include autoimmune hepatitis, hemolytic anemia, celiac disease (gluten intolerance), sarcoidosis (marked by lumps of inflammatory cells throughout the body) and myasthenia gravis (marked by weakness in voluntary muscles). 

           

          Pulmonary Exacerbations 

          Corticosteroids are useful in the treatment of exacerbations from asthma and chronic obstructive pulmonary disease (COPD). 

           

          Adrenal Insufficiency 

          Corticosteroids may be used to treat both primary and secondary adrenocortical insufficiency. This includes Addison’s disease, congenital adrenal hyperplasia, and adrenogenital syndrome. 

           

          Inflammatory Bowel Disease 

          Inflammatory bowel disease, such as the aforementioned Crohn’s disease, and ulcerative colitis may be treated with corticosteroids. 

           

          Neuro/Musculoskeletal Disorders 

          Corticosteroids are used in the treatment of ankylosing spondylitis (chronic inflammation of spinal joints), bursitis, polymyalgia rheumatica (marked by muscle pain and stiffness), osteoarthritis, and psoriatic arthritis. Corticosteroids can also treat neurological conditions like multiple sclerosis and Bell’s palsy (facial paralysis, often temporary). 

           

          Inflammatory Eye Conditions 

          Corticosteroids are useful in the systemic treatment of inflammatory ophthalmic conditions including optic neuritis, allergic conjunctivitis, and other conditions that cause inflammation of various structures of the eye. 

           

          Organ Transplant Rejection Prophylaxis 

          Renal transplant guidelines recommend corticosteroids in combination with other medications to prevent kidney rejection after transplantation (called induction therapy or immunosuppressant therapy). Corticosteroids are also indicated for heart and liver transplant rejection prophylaxis. 

           

          Cancer 

          Corticosteroids may be used for the palliative treatment of cancers including multiple myeloma and chronic lymphocytic leukemia (CLL). They may also be used to treat Hodgkin lymphoma (in conjunction with cancer medications), aggressive non-Hodgkin lymphoma, peripheral T-cell lymphoma, and neoplastic-associated hypercalcemia. 

           

          COVID-19 

          Although still in the investigative stages, the World Health Organization (WHO) recommends systemic corticosteroids as an adjunctive treatment for severe COVID-19 [6][13].

          Ask yourself...

          1. Do you prescribe/administer corticosteroids most frequently for acute or chronic conditions? 
          2. What is the most common indication for corticosteroid therapy you have witnessed in your practice? 
          3. Have you ever prescribed/administered corticosteroids for prophylaxis treatment alone? 
          4. Can you think of ways to minimize the severity of adverse effects of corticosteroid therapy among patients most at risk? 

          Mechanism of Action 

          As already mentioned, corticosteroids suppress the immune system. This is done by preventing protein synthesis in certain cells of the immune system (like macrophages and neutrophils), ultimately inhibiting their fighting potential [6][11]. More specifically, corticosteroids repress the activity of DNA within the immune cell – an activity that would otherwise serve as the beginning of protein synthesis.  

          Within immune cells, DNA sends messages to protein-making structures within the cell that prompts them to start making protein. However, the message must be “translated” or “decoded” (transcription) first before the structures can “understand” what to do [6][12]. Messenger RNA (mRNA) is the transcribed version of DNA. Corticosteroids work by making it difficult for DNA to be transcribed into mRNA.  

           

          Pharmacokinetics 

          The pharmacokinetics of corticosteroids differ based on drug type and route. The following is the pharmacokinetics of three common systemic corticosteroid drugs: prednisone, methylprednisolone, and dexamethasone [6]. 

           

          Prednisone 

          Prednisone comes in oral forms, both immediate-release (IR) and delayed-release. Prednisone IR is quickly absorbed in the gastrointestinal (GI) tract with a peak effect after one to two hours. Delayed-release tablets are released four hours after ingestion and peak after about six hours. Prednisone is metabolized by the liver and excreted by the kidneys. 

           

          Methylprednisolone  

          Methylprednisolone is rapidly absorbed orally and peaks within one to two hours. After IV administration, effects can occur within one hour with nearly complete excretion in 12 hours. When given as an injection in the joint, methylprednisolone absorption can occur over several days. This medication is distributed into various organs and body structures including the kidneys, intestines, skin, liver, and muscle. Methylprednisolone is metabolized by the liver and excreted by the kidneys. 

           

          Dexamethasone 

          Oral dexamethasone peaks in one to two hours. Absorption times for parenteral forms depends on the dosage and indication. For example, in patients with cerebral edema, treatment response from an IV dose of dexamethasone followed by an IM dose occurs in 12 to 24 hours [1]. Dexamethasone is rapidly distributed into the skin, intestines, liver, muscle, and kidneys. As with prednisone and methylprednisolone, this medication is metabolized by the liver and excreted by the kidneys.

          2. Why do you think it is important to know the mechanism of action of corticosteroids?  
          3. What is the main determining factor in prescribing/administering an oral corticosteroid as opposed to a parenteral form? 

          Contraindications and Precautions 

          Clinicians should not prescribe/administer prednisone to patients with an allergy to the drug or any components of its formulation. Precautions should be taken in patients with an allergy to other corticosteroids as cross-sensitivity can occur. Clinicians should also be aware that high-dose systemic corticosteroids place patients at risk for immunosuppression, especially when prescribed/administered with other immunosuppressant medications.  

          Although carrying a lower risk, moderate-dose and low-dose corticosteroid preparations should be monitored as well. Clinicians should avoid prescribing/administering these medications to patients with fungal or bacterial infections that are not well controlled with anti-infective medications.  

           

          Pregnancy and Breastfeeding Precautions 

          While corticosteroids are not contraindicated for pregnant or breastfeeding patients, clinicians have reason to be cautious when prescribing/administering these medications [6]. The following are precautions for pregnant and breastfeeding patients. 

          Pregnancy 

          If corticosteroids must be prescribed/administered during pregnancy, precaution should be taken as these medications cross the placenta and may be harmful to the fetus/infant (may cause adrenal insufficiency in the infant). Although the risks are small and inconsistent, oral or facial clefts (like cleft palate) may occur if systemic corticosteroids are prescribed/administered during the first trimester. 

          Breastfeeding 

          Corticosteroids are distributed into breastmilk. While no reported side effects have been reported in breast-fed infants, lower doses are recommended as high doses may cause problems with the infant’s growth and development. Corticosteroids can interfere with the infant’s ability to produce their own glucocorticoid hormones. With prednisone in particular, peak concentrations in breastmilk occur in about one hour after the dose is taken and it is recommended for patients to avoid breastfeeding during this time. However, the total daily dose of prednisone reaching the infant has been shown to be approximately 0.1% of the mother’s total daily dose [6].

          3. Have you ever been in a situation in which you had no choice but to prescribe/administer corticosteroids to a patient who was pregnant? 

          Adverse Effects 

          Corticosteroids given systemically can affect multiple body systems, particularly with prolonged use. Short-term use in high doses typically does not cause adverse effects [6]. Adverse effects of corticosteroids can be as mild as a rash to as severe as psychosis or a ruptured heart wall.  

          The following are adverse effects categorized by body systems [6]. 

          Neurological 

          Corticosteroids may increase intracranial and intraocular pressure which can lead to optic nerve damage and visual impairments. These medications can also lower seizure thresholds. Other neurological findings include headache, vertigo, and peripheral neuropathy. 

          Pulmonary 

          Corticosteroids can reactivate tuberculosis (TB) in patients who have a history of active TB. 

          Cardiovascular 

          Sodium retention, edema, and low potassium may occur in patients with high blood pressure or congestive heart failure (can also occur with renal failure/insufficiency). Left ventricular free-wall rupture can occur in patients with a recent myocardial infarction. Corticosteroids may also exacerbate arrhythmias and cause blood clots which may lead to a stroke. 

          Endocrine 

          Corticosteroids are known to decrease glucose tolerance and raise blood glucose levels. This can aggravate existing diabetes mellitus. Hypothalamic-pituitary-adrenal (HPA) suppression or signs/symptoms of Cushing’s syndrome (marked by high cortisol levels) can also occur with prolonged systemic use. 

          Gastrointestinal/Genitourinary 

          Corticosteroids can increase the risk of GI perforation and should therefore be monitored in patients with peptic ulcer disease, diverticulitis, or GI abscess. Additionally, esophageal ulcers and GI bleed may occur with use. Corticosteroids may cause weight loss, but can stimulate the appetite as well, leading to weight gain conversely. Menstrual irregularity may occur as well. 

          Musculoskeletal 

          Osteopenia (loss of bone density) and osteoporosis (more severe bone loss) can occur due to decreased bone formation, increased bone resorption, and inhibition of osteoblast function. Bone fractures (primarily in elderly patients) can occur as well. Acute generalized myopathy leading to quadriparesis (weakness in all extremities) may occur in patients with neuromuscular disease or those receiving neuroblocking medications. Muscle pain and waste can also occur due to protein depletion. 

          Skin 

          Corticosteroids may cause impaired wound healing due to protein depletion. Sweating, abnormal hair growth, and striae (stretch marks) can also occur with use. While corticosteroids may be useful in the treatment of rashes and itching, they can cause these symptoms as well. 

          Psychiatric 

          Psychiatric problems can occur with corticosteroid use, including euphoria, severe depression, anxiety, hallucinations, psychosis, personality changes, and withdrawn behavior. Patients may also experience insomnia, impaired cognition, mood swings, irritability, and restlessness. 

          Laboratory Changes 

          A common lab finding with corticosteroid use is leukocytosis (without an infectious or inflammatory cause). It is important for clinicians to differentiate between infectious and corticosteroid-related leukocytosis. Other lab findings may include low neutrophil count and abnormal electrolyte levels (high sodium, low calcium, and low potassium).

          4. How often do you consult another provider in prescribing corticosteroid therapy for patients with multiple comorbidities? Or how often do witness providers doing so? 

          Black Box Warning 

          Black box warnings are issued by the U.S Food and Drug Administration (FDA) to warn the public about the serious adverse effects of some medications. The most recent black box warning for corticosteroids was issued in 2014. The FDA warned against administering corticosteroid injections into the epidural space of the spine for the treatment of neck/back pain and radiating pain in the extremities [4]. When administered in this way, serious (although rare) adverse effects can occur including vision loss, stroke, paralysis, and death. 

          Drug Interactions 

          The therapeutic effect of corticosteroids may be counteracted or enhanced when administered with certain medications. Clinicians should perform an accurate medication reconciliation when prescribing/administering corticosteroids to ensure effective and safe treatment.  

          The following are medications that interact with corticosteroids categorized by a decreased or increased therapeutic effect [1]. Corticosteroid doses should be adjusted accordingly. 

           

          Decreased Therapeutic Effect 

          Medications that can decrease the level of corticosteroids in the blood when administered together include: 

          • Barbiturates 
          • Carbamazepine 
          • Ephedrine 
          • Phenytoin 
          • Rifampin 
          • Cholestyramine (affects oral corticosteroids in particular) 

           

          Increased Therapeutic Effect 

          Medications that can increase the level of corticosteroids in the blood when administered together include: 

          • Ketoconazole 
          • Macrolide antibiotics

          Clinical Guidelines on Corticosteroid Use in the Critically Ill 

          Clinical practice guidelines for corticosteroid therapy were developed to assist clinicians and providers in ensuring optimal prescribing and administration practices. Currently, guidelines are in place for corticosteroid use in critical illness. The most recent 2024 guidelines were reestablished for the treatment of septic shock, acute respiratory distress syndrome, and community-acquired bacterial pneumonia, particularly in adult patients.  

          In the following sections, these guidelines are compared with prior 2017 recommendations [3]. Clinicians practicing in acute care settings can use the following guidelines when prescribing/administering corticosteroids to patients who are critically ill. 

           

          Sepsis and Septic Shock 

          Previously, the guidelines recommend against administering corticosteroids in adult patients with sepsis without shock. Instead, corticosteroids were recommended in patients with septic shock not responsive to fluid and moderate- to high-dose vasopressor therapy. 

          Current Recommendation: Administer corticosteroids to adult patients with septic shock. Do not administer high dose/short duration corticosteroids for adult patients with septic shock (no more than 400 mg per day of a hydrocortisone equivalent for no more than three days). 

           

          Acute Respiratory Distress Syndrome  

          Previously, the guidelines recommended corticosteroid use in patients with early moderate to severe acute respiratory distress syndrome (PaO2/FIO2 of less than 200 and within 14 days of onset). 

          Current Recommendation: Administer to adult hospitalized patients with acute respiratory distress syndrome. 

           

          Community-Acquired Bacterial Pneumonia 

          Previously, the guidelines recommended corticosteroid use for five to seven days at a daily dose of less than 400 mg IV hydrocortisone (or equivalent) in hospitalized patients with community-acquired pneumonia. 

          Current Recommendation: Administer to adult patients hospitalized with severe bacterial community-acquired pneumonia. There is no recommendation for adult patients hospitalized with less severe bacterial community-acquired pneumonia.  

           

           

           

           

          Clinical Guidelines on Corticosteroid Use for COVID-19 

          While data is limited and still developing, both the World Health Organization (WHO) and the National Institutes of Health (NIH) developed clinical practice guidelines for the use of corticosteroids as a treatment for COVID-19.  

          Clinicians practicing in acute care settings can use the following guidelines when prescribing/administering corticosteroids to patients with COVID-19. 

           

          Global Guidelines for Corticosteroid Use for COVID-19 

          As mentioned earlier, the WHO recommends corticosteroids for the treatment of severe COVID-19 [6]. The 2020 “Corticosteroids for COVID-19: Living Guidance” recommendations are as follows [13]: 

          • The WHO recommends systemic corticosteroids rather than no corticosteroids for the treatment of patients with severe and critical COVID-19. 
          • The WHO suggests not to use corticosteroids in the treatment of patients with non-severe COVID-19. 

           

          National Guidelines for Corticosteroid Use for COVID-19 

          The National Institutes of Health (NIH) developed the 2023 “Therapeutic Management of Hospitalized Adults with COVID-19” guidelines outlining various drug therapy recommendations for patients with COVID-19, including corticosteroids. Recommendations are as follows [9][10]: 

          • The panel recommends against the use of dexamethasone (or other systemic corticosteroids) for the treatment of COVID-19 in patients who do not require supplemental oxygen. 
          • The panel recommends against the use of dexamethasone (or other systemic corticosteroids) in nonhospitalized patients in the absence of another indication. 
          • The panel recommends patients with COVID-19 receiving dexamethasone (or another corticosteroid) for an underlying condition to continue this therapy as directed by their health care provider.

          Patient Education 

          Therapeutic and safe corticosteroid use is dependent on safe prescribing and administration practices, as well as patient compliance. Optimal patient education is vital for successful treatment with corticosteroids.  

          The following are teaching points to share with patients about corticosteroid use [1][6][7]. 

          • Adverse Effects: Patients should be informed of common adverse effects, particularly elevated blood sugar, mood changes, appetite changes, and weight gain. 
          • Vaccine Safety: Patients should be encouraged to check with their health provider before receiving vaccines (Corticosteroids should not be given with live vaccines) 
          • Infection Risk: Patients should be informed of the risk for developing an infection when corticosteroid doses are high or used to suppress the immune system, and to therefore avoid exposure to chickenpox or measles. 
          • Administration: Patients should be instructed to avoid abruptly stopping corticosteroids to prevent adrenal insufficiency and potentially death. They should also be made aware that stress on the body (for example, when having surgery) may require additional doses of corticosteroids.

          Future Implications 

          Corticosteroid use may be on the rise. As aforementioned, corticosteroids are useful in the treatment of autoimmune disease. In the U.S., researchers anticipate a rise in autoimmune diseases in the future.  

          In a 2020 study in Arthritis and Rheumatology, researchers noted that the prevalence of antinuclear antibodies (ANA) (markers of autoimmune disease) is increasing in the U.S. [8]. The study analyzed the antibodies of over 14,000 participants (age 12 and older) over the course of three time periods. Results revealed the following: 

          • From 1988 – 1991, 22 million people had antibodies. 
          • From 1999 – 2004, 27 million people had antibodies. 
          • From 2011 – 2012, 41 million people had antibodies. 

          The study also found that antibody prevalence is highest among males, non-Hispanic whites, adults over age 50, and adolescents. Young people age12 to 19 had the highest antibody prevalence. While it is unclear why this is the case among the youth, the study findings may suggest an increase in the use of corticosteroids in the future. Further, clinicians might anticipate changes in clinical guidelines for safe prescribing/administration practices.

          Anti-Arrhythmics

          Introduction   

          Cardiac arrhythmias continue to present significant clinical challenges and remain a cause common of death and disability [5]. Arrhythmias encompass a wide array of heart rate and rhythm disturbances; they are classified into broad terms as bradyarrhythmia’s (heart rates below 60 beats per minute) and tachyarrhythmias (heart rates exceeding 100 beats per minute) [10].

          The defining feature of cardiac arrhythmias is an irregular heartbeat, or a symptom of abnormal heart rhythm linked to irregular initiation of electrical impulses, or a combination of both factors.

          The mechanisms underlying cardiac arrhythmias are complex. The management of these conditions often involves the administration of antiarrhythmic drugs. It is vital that prescribers are aware of the pharmacokinetics of this drug class.

          Overview of Cardiac Arrhythmias 

          Arrhythmias impact an estimated 17 million individuals across the planet, they rank among the most prevalent forms of heart disease [8]. The clinical manifestations of arrhythmias vary from asymptomatic individuals to sudden cardiac death (SCD), contributing to 10–15% of all mortality cases [10].  

          The only pattern considered to be a normal heart rhythm is the normal sinus rhythm. In this state, an electrical impulse originates in the sinoatrial (SA) node and travels through the heart [1]. This delayed impulse occurs in the atrioventricular (AV) node, then it proceeds through the His-Purkinje network, which encompasses the bundle of HIS, the left and right bundle branches, and the Purkinje fibers [1]. These reactions essentially coordinate each beat of the heart. 

          Despite the notable limitations associated with existing antiarrhythmic medications, pharmacological intervention remains a fundamental aspect of managing cardiac arrhythmias [5]. Research suggests that arrhythmias occur in 1.5% to 5% of the general population, with atrial fibrillation being the most prevalent form [1, 10].  

          Arrhythmia refers to any deviation from the heart's normal rhythm, with the normal sinus rhythm being the baseline for a healthy heart rhythm [1]. The categorization of arrhythmias occurs through various criteria, with the most prevalent method being the heart rate of conduction. This includes bradyarrhythmia’s, where the heart beats slower than 60 beats per minute (bpm), and tachyarrhythmias, where the heart rate exceeds 100 bpm [1].  

          Atrial fibrillation (AF) is the most frequent occurring sustained cardiac arrhythmia and linked to heightened morbidity and mortality rates, in addition to increased healthcare costs [2][3].  

          Arrhythmias may originate from congenital anomalies (present from birth) or can develop due to irritation or damage to the myocardial tissue, causing disruptions or ‘short circuits’ in the heart's electrical system [13].  

           

          Basics of Antiarrhythmic Drugs (AADs) 

          Antiarrhythmic drugs (AADs) continue to be fundamental in the management of cardiac arrhythmias and classified based on the cardiac action potential [4]. The action of these drugs works toward the immediate cessation of atrial and ventricular arrhythmias (acute cardioversion) and for the long-term prevention of arrhythmia recurrence to maintain normal sinus rhythm [5].  

          A limited number of new AADs have reached the market despite the growing incidence of cardiac arrhythmias [5].  

          Two key objectives define the rationale for treating arrhythmias: (1) to mitigate significant clinical symptoms, including weakness, syncope, or the onset or worsening of congestive heart failure caused by an arrhythmia, and (2) to extend the patient's lifespan [8].  

          In the initial stages of antiarrhythmic drug (AAD) development, the primary focus was on controlling ventricular arrhythmias [6]. The direction of treatment changed following the adverse outcomes highlighted by the Cardiac Arrhythmia Suppression Trial (CAST) and the Survival with Oral D-Sotalol (SWORD) trial, which demonstrated that patients receiving AADs (encainide or flecainide) fared worse than those on placebo [6].  

          The primary criterion of antiarrhythmic drugs is safety. In the last decade antiarrhythmic drugs have been subject to intense reevaluation, prompted by the outcomes of large-scale human research studies that highlighted various risks and limitations associated with pharmacological treatments for arrhythmias [7].  

          In the Atrial Fibrillation Follow-up Investigation of Rhythm Management (AFFIRM) study, the trial demonstrated that although achieving rhythm control was associated with improved survival the adverse effects negated survival benefits [8].

          2. How can healthcare professionals balance the immediate need for rhythm control with the long-term goal of minimizing adverse effects and mortality? 

          Definition 

          Antiarrhythmic agents, often referred to as cardiac dysrhythmia medications, constitute a category of pharmaceuticals designed to moderate the heart’s electrical impulse and mitigate rapid heart rhythms; these rhythms include atrial fibrillation (AF), supraventricular tachycardia (SVT), and ventricular tachycardia (VT) [11].  

          This class of drugs influence cardiac ionic channels or receptors, modifying the cardiac action potential, or its creation and transmission [11]. These alterations affect the activation spread or repolarization pattern, suppressing cardiac arrhythmias [12].  

          Common symptoms of arrhythmias include heart fluttering, abnormal or rapid heart rhythms, lightheadedness, fainting spells, chest pain, and breathlessness. Individuals may also experience heart palpitations, dizziness or feeling faint, chest pain or discomfort, weakness, and fatigue [12].

          2. Do you have experience administering antiarrhythmic medications to patients? 

          Classification of Antiarrhythmic Medications 

          The categorization of arrhythmias is based on the location within the conduction pathway where they originate.  

          There are two main groups:  

          • Supraventricular - originating from the atria or the atrioventricular (AV) node. 
          • Ventricular - occur distal to the AV node.  

          [23] 

           

          Prior to 2018, the categorization of antiarrhythmic drugs was based on the Vaughan-Williams (VW) classification system, which organized these medications by their principal mechanism of action [4, 14]. The initial Vaughan-Williams classification had limitations. When introduced in the 1970s, the range of antiarrhythmic drugs focused on altering the function of Na+, K+, and Ca2+ channels, as well as targeting intracellular processes governed by adrenergic activity [15]. 

          Today, there is a broader range of advanced antiarrhythmics, many possessing overlapping interactions with drugs in other classes. For example, amiodarone, categorized under Class III (Potassium channels blockers), also exhibits sodium and calcium-channel blocking properties (Class IV).

          Ivabradine is designed to lower heart rate. It is used in the management of stable angina pectoris and chronic heart failure with heart rate ≥70 bpm across various clinical scenarios, including those with either preserved or compromised left ventricular (LV) function.  

          Ivabradine is effective by decreasing heart rate while preserving myocardial contractility and coronary vasomotor responsiveness, thereby reducing oxygen consumption, and extending diastolic duration [16] [17].

          Class I: Voltage-gated Na+ Channel Blockers 

          Class IA 

          Class IA medications block fast sodium channels and include agents such as quinidine, procainamide, and disopyramide [11]. Quinidine, disopyramide, and procainamide are used in the management of supraventricular tachyarrhythmias, recurrent atrial fibrillation, ventricular tachycardia, ventricular fibrillation, Brugada syndrome, and Short QT Syndrome (SQTS) [4].  

          These drugs are associated with the highest risk of proarrhythmic among sodium channel blockers due to their capacity to prolong the QTc interval, which restricts their use because of their proarrhythmic potential [11].  

          For patients with Brugada syndrome, Quinidine is an alternative to implantable cardioverter-defibrillator (ICD) placement [66].  

          This class has also shown utility in individuals with short QT syndrome experiencing recurrent ventricular arrhythmias (VAs), reducing the frequency of ICD shocks in these patients [66].  

          Disopyramide is employed in cases of hypertrophic obstructive cardiomyopathy (HOCM), when combined with a beta-blocker or verapamil to alleviate symptoms like angina or dyspnea in patients unresponsive to beta-blockers or verapamil alone [67].  

          Procainamide is useful for exposing and diagnosing Brugada syndrome in individuals suspected of the condition but without a confirmed diagnosis [68]. Procainamide has shown to reestablish sinus rhythm in patients with Wolff-Parkinson-White (WPW) syndrome who experience atrial fibrillation (AF) without hemodynamic instability, which is marked by a wide QRS complex or a rapid pre-excited ventricular response [69]. Procainamide may also assist in terminating ventricular tachycardia and other arrhythmias [69].

How might the proarrhythmic potential of these drugs and their ability to prolong the QTc interval influence the decision-making process in selecting an appropriate treatment strategy for patients with conditions like Brugada syndrome, Short QT Syndrome (SQTS), or Wolff-Parkinson-White (WPW) syndrome? 

          Class IB

          Lidocaine and Mexiletine treat ventricular tachycardia and ventricular fibrillation after a myocardial infarction by inducing a mild blockade of sodium channels [4]. These are not effective for treating atrial arrhythmias [4].  

          In the context of long QT syndrome, mexiletine is capable of reducing the QTc interval and has been employed to decrease the incidence of recurrent arrhythmias and the need for interventions by implantable cardioverter-defibrillators (ICDs) [70].  

          The effectiveness of Lidocaine diminishes in instances of hypokalemia, necessitating the correction of potassium levels [80].

          Top of Form 

           

          Class IC 

          Research recommends Encainide (Enkaid), flecainide (Tambocor), and propafenone (Rythmol SR) for managing supraventricular and ventricular tachyarrhythmias that do not respond to standard treatments, in the absence of underlying structural heart disease. [72].  

          Propafenone increases the effects of cyclosporin, desipramine, and theophylline [81]. 

          Class IC is used to treat premature ventricular contractions and catecholaminergic polymorphic ventricular tachycardia [18]. These drugs block sodium channels without altering the QT interval and suit ongoing management in individuals with symptomatic supraventricular tachycardia (SVT) who have no structural or ischemic heart disease, and either are unsuitable for or opt against catheter ablation. [11].  

          In addition, these agents are effective for the pharmacological cardioversion of atrial fibrillation (AF). The “pill in the pocket” strategy involves patients with paroxysmal AF carrying a loading dose of medication to take at the onset of an AF episode. This approach aims for chemical cardioversion to restore normal rhythm, rather than adhering to a regular maintenance dose regime [71].  

          The Cardiac Arrhythmia Suppression Trials (CAST I and II) showed that patients with a history of myocardial infarction, treated with class IC agents (flecainide, encainide, moricizine) to reduce premature ventricular contractions (PVCs), faced a higher mortality risk compared to those receiving placebo [72].

          Class II: Autonomic Inhibitors/Activators 

          The literature recommends beta-blockers (BB) for managing the heart rate in individuals with paroxysmal, persistent, or permanent atrial fibrillation (AF) and atrial flutter [73]. Beta-blockers (BB) are also beneficial for long-term management in patients with symptomatic supraventricular tachycardia (SVT) [73].  

          Due to their favorable safety profile and efficacy, healthcare professionals can consider beta-blockers as the first-choice therapy for ventricular arrhythmias [39]. Their use is associated with a reduction in adverse cardiac events in conditions such as long QT syndrome and catecholaminergic polymorphic ventricular tachycardia [74].  

          For patients exhibiting symptomatic premature ventricular contractions (PVCs) in the absence of underlying heart disease, beta-blocker therapy can help decrease the frequency of recurrent arrhythmias and alleviate symptoms [75].

          IIa: Inhibitors including pindolol, carvedilol, timolol, nadolol (non-selective beta-blockers), and bisoprolol, atenolol, metoprolol, esmolol (selective beta-1 blockers) treat rate control in atrial fibrillation, atrial flutter, and ventricular tachyarrhythmia [4]. 

          IIb: Activators: The use of Isoproterenol can manage ventricular escape rhythm in cases of complete AV block before pacemaker implantation [4][20]. 

          IIc: Inhibitors: Atropine treats symptomatic sinus bradycardia and conduction block [4][21]. 

          IId: Activators: For the management of supraventricular tachyarrhythmias, Carbachol, methacholine, and digoxin [4]. 

          IIe:Activators: Adenosine for the cessation of paroxysmal supraventricular tachycardia (PSVT) [22]. 

           

          Class III: K+ Channel Blockers/Openers 

          Potassium channel blockers decrease potassium efflux out of the cell and prolong the QTc interval [4] Amiodarone displays sympatholytic effects as well as sodium and calcium channel blocking properties, leading to reduced conduction through the AV and sinus nodes [4].  

          Amiodarone helps maintain sinus rhythm in patients with atrial fibrillation (AF) and those suffering from left ventricular systolic dysfunction [4].  

          Amiodarone also stands as a viable choice for pharmacological cardioversion and can help manage ventricular rate in critical patients without pre-excitation, though it is less effective than non-dihydropyridine calcium channel blockers [4] [49].  

          Amiodarone is the preferred antiarrhythmic medication for suppressing ventricular arrhythmias (VA) [4]. Administration of intravenous amiodarone may achieve rhythm stabilization in cases of unstable persistent ventricular arrhythmias (VA) following defibrillation [49]. Administering intravenous amiodarone stabilizes rhythm in cases of unstable persistent ventricular arrhythmias (VA) following defibrillation.  

          In addition, amiodarone controls ventricular arrhythmias (VA) in patients with ischemic heart disease who are also receiving beta-blocker treatment [4].  

          Observations show that Dronedarone reduces hospital admissions for atrial fibrillation (AF) in individuals with a history of non-permanent AF who are in sinus rhythm. However, for patients with permanent AF that cannot convert back to normal sinus rhythm, it is contraindicated due to FDA reviews indicating a significant increase in the risk of cardiovascular death, stroke, and heart failure in these cases [76]. 

          Dofetilide is employed in the treatment of atrial arrhythmias and for the acute pharmacological cardioversion of atrial fibrillation or flutter [77].  

          Sotalol, combining class II beta-blocker properties and class III potassium channel blocker effects, manages both ventricular and supraventricular arrhythmias. [78].  

          Ibutilide (Corvert) targets the treatment of atrial fibrillation or flutter, underlining its specialized use in managing these specific arrhythmias [79].

          IIIA: Voltage-dependent K+ channels 

          Amiodarone and dronedarone are notable for their role as non-selective potassium (K+) channel blockers, which are crucial in the treatment of unstable ventricular tachycardia and life-threatening recurrent ventricular fibrillation [4]. 

           

          Kv11.1 (rapid K+ current) blockers: Dofetilide, almokalant, ibutilide, sematilide, and sotalol manage ventricular tachycardia in patients without prior myocardial infarction or underlying structural heart disease. They also treat Wolff-Parkinson-White (WPW) syndrome when associated with atrial fibrillation [4]. 

          Kv1.5 (ultra-rapid K+ current) blockers: Vernakalant serves to convert recent onset atrial fibrillation in patients without structural or ischemic heart disease. It is important to note that the FDA does not approve this specific use of vernakalant [24]. 

          IIIb: Metabolically dependent K+ channels blockers: Nicorandil and pinacidil are employed as second-line treatments for stable angina [25]. 

           

          Class IV: Ca2+ handling modulators 

          Non-dihydropyridine calcium channel blockers, such as diltiazem and verapamil, reduce conduction speed and decelerate signal transmission through the AV node [82]. These medications are effective for controlling the ventricular rate in both acute and chronic cases of atrial fibrillation (AF) and atrial flutter [82].  

          In the acute management of stable patients with supraventricular tachycardia (SVT), including focal and multifocal atrial tachycardias, diltiazem and verapamil serve as viable treatment options [4] [39].

          Clinical Prescribing Criteria  

          Antiarrhythmic medications are pivotal in managing symptoms and safeguarding against the decline of cardiac function caused by conditions such as tachycardia, irregular rhythms, or desynchrony [4]. The primary objective is to reestablish normal cardiac rhythm and conduction, averting the onset of more severe and fatal arrhythmias. 

          Antiarrhythmics have a narrow therapeutic index, indicating a minimal margin between the effective dosage and the onset of toxicity [4]. There is a tenuous balance between suboptimal treatment and the risk of toxic or proarrhythmic effects, underscoring the importance of precise dosing and monitoring. Clinical attention focuses on the patient's clinical status, underlying structural and functional conditions, and the mechanisms of arrhythmia at both cellular and molecular levels.  

          The use of antiarrhythmic drugs in therapy seeks to alter conduction velocity, by either slowing down or speeding it up, modify the excitability of cardiac cells via changes in the length of the effective refractory period, and suppress unusual spontaneous activity [14]. 

          Numerous variables influence the effectiveness of antiarrhythmic drugs, such as race, sex, genetics, environmental temperature, drug interactions, precipitating factors, changes in neurohormones, the disease's present condition and severity, and disease-driven structural changes in the body [30]. The complexity increases with some antiarrhythmic drugs (AADs) displaying diverse electrophysiological and pharmacological effects that depend on the administration route, plasma concentration, and the existence of active metabolites. 

          A variety of factors can influence the efficacy of medications, including racial background, gender, genetic makeup, ambient temperature, interactions between different drugs, initiating triggers, neurohormonal fluctuations, the current state and intensity of the disease, and alterations in the body's structure caused by the disease itself [31].  

          Complicating the pharmacology, certain antiarrhythmic drugs (AADs) exhibit a wide range of electrophysiological and pharmacological actions, which can vary based on the method of administration, concentration levels in the plasma, and the presence of active metabolites [4] [5].

          The Cardiac Electrical Cycle (Electrical Cascade) 

          The cardiac action potential represents the sequence of ion exchanges that result in the successive depolarization and repolarization of the cardiac myocyte, culminating in muscle contraction [4]. During its resting phase, a cardiac myocyte maintains a baseline resting membrane potential ranging from negative 80 to negative 90 millivolts [32].  

          Antiarrhythmic drugs slow down ion movement during various stages of the cardiac action potential [32]. 

           

          • Phase 0:The “depolarization” phase of the action potential occurs due to the influx of sodium ions (Na+) into the cell, following an electrochemical gradient, leading to a membrane potential of around positive 30 millivolts [33]. 
          • Phase 1: “The notch,” or the early repolarization phase of the action potential, features potassium (K+) ions flowing out. [4] [33]. 
          • Phase 2:“The plateau” phase occurs when the inward movement of calcium ions (Ca2+) balances the outward movement of potassium (K+) ions [4] [34]. 
          • Phase 3:“The repolarization” phase of the action potential occurs through the efflux of potassium (K+) ions along their electrochemical gradient out of the cell. This movement removes the positive charge of the K+ ion from the cell, reinstating the cardiac myocyte's negative potential [33][34]. 
          • Phase 4:Reactivation of the Na/K-ATPase pump, which re-establishes the resting membrane potential in the cardiac myocyte [4][35].

          Pharmacokinetics of Anti-Arrhythmic Medications 

          Pharmacokinetics involves the study of drug absorption, distribution, metabolism, and excretion. All antiarrhythmic drugs affect the conductance of membranes and ions, modifying cardiac action potential dynamics either via direct or indirect action.  

          For example, some medications inhibit fast sodium channels, essential for controlling the rate of membrane depolarization (phase 0) during an action potential [33]. Electrical conduction velocity links to membrane depolarization and blocking sodium channels slows this velocity down [32][33]. Slowing conduction velocity is advantageous for eradicating tachyarrhythmias resulting from reentry circuits [36].  

          Various antiarrhythmic drug classes affect the duration of action potentials and the effective refractory period [37]. Extending the effective refractory period often eradicates reentry tachyarrhythmias [38]. This effect occurs by inhibiting potassium channels and postponing the repolarization phase (phase 3) of action potentials [38].  

          Medications that inhibit the slow inward calcium channels aim to diminish pacemaker activity by decelerating the depolarizing pacemaker potential’s rate of rise (phase 4 depolarization) [14].  

          These drugs also decrease the speed of electrical signal transmission through the atrioventricular (AV) node [14][38]. Similar to sinoatrial (SA) node cells, AV nodal cells rely on the influx of calcium ions for depolarization [34]. Due to the potential for sympathetic nervous system activity to cause arrhythmias, beta1-adrenoceptor blockers are employed to diminish the sympathetic impact on the heart [39]. These beta-adrenoceptors connect to ion channels through specific signal transduction pathways, indicating that beta-blockers modify ion conductance across the membrane, influencing calcium and potassium conductance [39].  

          In instances of AV block, doctors sometimes use drugs like atropine, a muscarinic receptor antagonist, to counteract vagal effects [40]. AV block can emerge as an adverse effect of beta-blocker medication, and stopping the beta-blocker in such cases may return AV conduction to normal [41].  

          An increased ventricular rate can be a consequence of atrial flutter or fibrillation [42].  
          In response, medications that slow down conduction through the atrioventricular (AV) node regulate the ventricular rate. Calcium channel blockers and beta-blockers are particularly effective for this purpose [4].  

          Digoxin proves advantageous for patients with systolic heart failure, also referred to as heart failure with reduced ejection fraction (HFrEF), characterized by an ejection fraction of less than 40% [43]. Nonetheless, it does not contribute to a reduction in mortality [43]. When standard treatments do not achieve heart rate objectives in atrial fibrillation or atrial flutter, clinicians can deploy Digoxin for heart rate management [44].  

          Administration of digoxin is contraindicated in instances of pre-excitation due to accessory pathways since it promotes AV blockade and could precipitate ventricular tachyarrhythmias [44]. In conditions of elevated sympathetic activity, digoxin is ineffective, and beta-blockers are the preferred treatment option [44].  

          Healthcare providers favor oral drug formulations for their improved patient compliance, ease of use, and scalability, which offer economic advantages [45]. However, the oral bioavailability of drugs can vary, influenced by differences in physicochemical characteristics and metabolic activities that impact pharmacokinetics [46]. Challenges such as intestinal metabolism, efflux mechanisms in the gastrointestinal tract, and the hepatic first-pass effect hinder the bioavailability of drugs administered orally [46] [47].  

          The first-pass effect describes a pharmacokinetic process in which a drug undergoes metabolism at a specific site in the body before reaching the systemic circulation or its intended site of action, which reduces the concentration of the active drug available [47]. The liver, a primary location for drug metabolism, has a direct link to the first-pass effect. This effect can also occur in other active metabolic areas of the body, such as the lungs, blood vessels, gastrointestinal tract, and various tissues [47].

          2. What strategies can healthcare providers employ to mitigate potential adverse effects, including those related to the first-pass effect? 
          3. Given the varied mechanisms by which antiarrhythmic drugs modify cardiac action potentials and conduction velocities to treat arrhythmias, how do these mechanisms align with the selection of specific antiarrhythmic medications for conditions such as atrial flutter, atrial fibrillation, and AV block, considering both the intended therapeutic outcomes and the potential for adverse effects? 
          Absorption 

          Antiarrhythmic medications exhibit quick absorption, but the pronounced first-pass effect often reduces their bioavailability [47]. They achieve peak plasma concentrations within 1–3 hours, except for digoxin and dronedarone, which reach their peak in 3–6 hours, and amiodarone, which takes 6–8 hours to peak [11]. In elderly individuals and patients with liver dysfunction, the oral bioavailability of medications tends to be higher [11].  

          Intestinal bacteria transform digoxin into inactive compounds; antibiotics such as tetracycline and erythromycin eliminate these bacteria, leading to elevated levels of digoxin in the bloodstream [44]. The antiarrhythmic effect of digoxin starts within 2–5 minutes after its intravenous administration [44]. 

          The absorption of drugs through the gastrointestinal tract is crucial for their bioavailability, with meals playing a role that can either enhance or impede this process [46]. For instance, a high-fat meal can increase the oral absorption of dronedarone by fourfold [11].

          1. How do factors such as age, liver function, intestinal flora, and dietary habits influence the therapeutic levels and efficacy of these drugs in the bloodstream? 
          Distribution 

          With the exception of sotalol, antiarrhythmic drugs (AADs) exhibit some degree of binding to plasma proteins [11]. Amiodarone, digoxin, flecainide, and propafenone build up in the heart at concentrations higher than those in plasma and dialysis cannot remove them [11].  
          The concurrent administration of flecainide and amiodarone increases flecainide plasma concentrations by 50% [48].  

          Disopyramide, mexiletine, sotalol, and verapamil can cross the placenta and appear in breast milk. High concentrations of Procainamide also occur in breast milk and eliminated by newborns [11].  

          Oral administration of amiodarone reaches steady-state plasma concentrations after an extended period, except when administered in substantial loading doses; delivering it via intravenous form also delays its maximal effect [49]. This delay is indicative of its distribution across multiple compartments, including the intravascular compartment, which a standard loading dose saturates, a peripheral compartment encompassing various tissues, and a deep compartment represented by adipose tissue, serving as a reservoir for the drug [49].  

          Amiodarone is known for its distinctive side effects, with a 15% prevalence rate in the first year of use, which can escalate to up to 50% with prolonged treatment [87]. Side effects include pulmonary fibrosis, thyroid dysfunction, photosensitivity, blue-grey skin discoloration, corneal microdeposits, peripheral neuropathy, and elevated liver enzymes [87]. Providers must weigh the potential benefits of amiodarone against its long-term risks [94].

          Ask yourself...

          1. How does the differential binding of antiarrhythmic drugs to plasma proteins and their accumulation in various body compartments (heart and adipose tissue) affect their pharmacodynamics and pharmacokinetics? 
          Biotransformation 

          Antiarrhythmic drugs (AADs) undergo metabolism in the liver through CYP450 isoenzymes, resulting in active metabolites that either block sodium (Na+) channels (such as mexiletine and propafenone), extend action potential duration (APD) [for instance, N-acetylprocainamide (NAPA)], or cause central nervous system (CNS) toxicity (as seen with lidocaine) [11].  

          Genetics influence the metabolism of CYP2D6 resulting in higher plasma concentrations and extended half-lives (t½) of metoprolol and propafenone in individuals with poor metabolizing capabilities (6% of Caucasians) compared to those who are rapid metabolizers [50]. In similar fashion, the conversion of procainamide to N-acetylprocainamide (NAPA) varies, with 15–20% metabolized in individuals classified as 'slow-acetylators' and 25–33% in 'fast-acetylators' [11].  

          These metabolic phenotypes are determined by genetics. There are no standard tests available to identify a patient's metabolic phenotype prior to treatment initiation, with the exception of measuring the procainamide/NAPA concentration ratio. It is advisable to decrease dosages for poor or slow metabolizers to two-thirds or less of the standard maintenance dose [11] [51].  

          Lipophilic beta-blockers, such as bisoprolol, carvedilol, metoprolol, and propranolol, undergo metabolism via CYP2D6, and their bioavailability and half-life (t½) are prolonged in cases of liver dysfunction [11]. The body excretes hydrophilic beta-blockers, including atenolol and sotalol, in their unchanged form through the urine [11].  

          Following an intravenous loading dose, lidocaine undergoes metabolism with a half-life (t½) of 1.5–2 hours. In patients with liver impairment or decreased hepatic blood flow — including the elderly, those experiencing cardiogenic shock, heart failure, myocardial infarction, or those taking cimetidine and beta-blockers — lidocaine's plasma levels increase, and its half-life extends [51]. In these cases, one should lower both the loading and maintenance doses.  

          Due to its brief half-life, an initial loading dose of lidocaine requires supplementation with a continuous infusion or repeated administrations to achieve and maintain a consistent plasma concentration [53].  

          Intravenous Esmolol undergoes rapid hydrolysis in red blood cells, with a half-life of 9 minutes, and achieves complete reversal of beta-blockade 20–30 minutes after drug cessation [11]. Intravenous adenosine acts within 15–30 seconds, with erythrocytes and vascular endothelial cells absorbing and metabolizing it through adenosine deaminase (ADA), leading to a short half-life (t½) of less than 10 seconds [11].

          Self Quiz

          Ask yourself...

          1. How do genetic variations in CYP450 isoenzymes (CYP2D6) affect the metabolism, efficacy, and safety of antiarrhythmic drugs? 
          Elimination 

          Antiarrhythmic drugs (AADs) vary in their extent of excretion through urine and feces [11]. The half-life (t½) of these drugs extends in elderly individuals and patients with renal impairment (such as digoxin, disopyramide, dofetilide, flecainide, procainamide, and sotalol) or liver dysfunction (including amiodarone, diltiazem, flecainide, lidocaine, metoprolol, mexiletine, propafenone, propranolol, quinidine, and verapamil) [11]. This prolongation also occurs in congestive heart failure (seen with amiodarone, flecainide, lidocaine, mexiletine, procainamide, and quinidine) or after a myocardial infarction (noted with disopyramide, lidocaine, and mexiletine) [11][54].  

          For these patients, it is advisable to lower the dosages and to conduct regular ECG monitoring. Amiodarone is subject to extensive metabolism in the liver, excreted through the bile, and has a prolonged half-life (t½) ranging from 25 to 110 days. This extended half-life accounts for the persistence of its effects for weeks or even months following cessation of the drug [11][55].  

          Due to their short half-life (t½), manufacturers dispense certain antiarrhythmic drugs, including beta-blockers, diltiazem, propafenone, and verapamil, in modified-release formulations [11].  

          Amiodarone, cimetidine, diltiazem, ketoconazole, procainamide, propranolol, and verapamil elevate plasma concentrations of quinidine [11]. Quinidine acts as a strong inhibitor of CYP2D6 and P-glycoprotein (P-gp), raising the plasma levels of drugs metabolized by this enzyme; it also reduces digoxin clearance, necessitating a 50% reduction in digoxin dosage [11]. Beta-blockers, cimetidine, and halothane cause an increase in plasma concentrations of lidocaine, thereby requiring a reduction in lidocaine dosage [11]. In addition, mexiletine elevates the plasma levels of theophylline, while amiodarone increases the levels of mexiletine [56]. 

          Flecainide and propafenone lead to higher plasma concentrations of digoxin and propranolol. Propafenone (Rythmol) raises the plasma levels of digoxin, metoprolol, propranolol, and warfarin [48]. Mexiletine and quinidine amplify the effects of warfarin; thus, it is advisable to decrease the dosage of warfarin and monitor the prothrombin time/international normalized ratio (INR) [11] [48].  

          Amiodarone inhibits P-glycoprotein (P-gp) and several cytochrome P450 isoenzymes, such as CYP1A2, CYP2C9, CYP2D6, and CYP3A4, thus increasing the plasma concentrations of drugs metabolized by these pathways or that are substrates of P-gp [94]. Dosage modifications are necessary for medications such as digoxin, flecainide, and warfarin; it is also important to monitor digoxin concentrations and the international normalized ratio (INR) [57][58].  

          Cholestyramine may decrease the absorption of amiodarone [59]. Since diltiazem and verapamil inhibit both CYP3A4 and P-glycoprotein (P-gp), adjusting the dosages of drugs metabolized by CYP3A4 or are substrates of P-gp becomes necessary [59]. Furthermore, verapamil has the capacity to suppress the liver's metabolism of lipophilic beta-blockers, resulting in elevated plasma concentrations of these medications [60].  

          There is a significant pharmacokinetic interaction between certain antiarrhythmic/rate controlling medications (such as amiodarone, quinidine, dronedarone, verapamil, digoxin, and diltiazem) and non-vitamin K antagonist oral anticoagulants (NOACs) due to competition for P-glycoprotein (P-gp) or inhibition of CYP3A4 (notably by diltiazem, dronedarone, and verapamil) [61] [62].  

          Due to these interactions leading to elevated plasma levels of NOACs, experts advise against combining dronedarone with dabigatran and recommend reducing the dose of edoxaban by 50% [62] [63]. Consider reducing the dose of all non-vitamin K antagonist oral anticoagulants (NOACs) when administering amiodarone alongside other P-gp competing substances [64].  

          Prescribers recommend reducing the dose of dabigatran (Pradaxa) when used with verapamil. Combining edoxaban with verapamil, especially when other P-gp competitors are present, may also necessitate a dose reduction [65].

          2. What principles should guide the adjustment of dosages in patients with such conditions to maintain therapeutic efficacy while minimizing toxicity? 
          Other Antiarrhythmic Drugs 
          • Adenosine is effective for both diagnosing and halting supraventricular tachycardia (SVT) arising from atrioventricular nodal reentrant tachycardia (AVNRT) or orthodromic atrioventricular reentrant tachycardia (AVRT) [83]. Adenosine serves as a diagnostic aid by revealing underlying atrial flutter or atrial tachycardia (AT) [83]. Adenosine can also terminate focal AT caused by a triggered mechanism and distinguish focal AT from AVNRT and AVRT [83]. Adenosine, a purine nucleoside, results from the breakdown of adenosine triphosphate [86]. Within cardiomyocytes, it interacts with Gi-protein type 1 receptors, facilitating swift potassium efflux and hyperpolarization, while also inhibiting calcium influx [86]. These actions decrease the heart rate and slow down conduction velocity by targeting the AV node. 
          • Digoxin is not a first-line therapy for ventricular rate control in patients with AF, a combination of digoxin and beta-blocker/or non-dihydropyridine calcium channel blockers is a reasonable rate control option in patients with AF and heart failure [84]. 

           

          Treatment of Overdose  

          In instances of antiarrhythmic drug overdose, medical professionals must ensure the patient has a clear airway, adequate breathing, and support for circulation [4] [87]. Managing cardiac arrest and severe toxicity from poisoning involves the use of specialized interventions, including antidotes and venoarterial extracorporeal membrane oxygenation (VA-ECMO), alongside fundamental and advanced life support techniques [87].  

          Symptoms such as nausea, vomiting, neurological manifestations, and lethal arrhythmias characterize Digoxin toxicity [88]. To treat ventricular tachyarrhythmias from digoxin toxicity, clinicians can use lidocaine, and atropine serves as an option for bradyarrhythmia’s. In addition, digoxin-specific antibody fragments prove effective in severe toxicity cases [89].  

          Therapeutic and excessive dosages of dofetilide may induce Torsades de Pointes (TdP), which clinicians manage by reducing or stopping the drug's dosage [90]. If the arrhythmia persists, initial treatment involves activated charcoal if ingestion occurred within the last 15 minutes, followed by intravenous magnesium and correction of any electrolyte imbalances [90].  
          For persistent arrhythmias, administering isoproterenol/dopamine may serve as a temporary measure until initiating pacing [90]. 

          In cases of beta-blocker poisoning, treatments involve administering catecholamines, applying high-dose insulin euglycemic therapy, and using vasopressors, noting glucagon for its positive effects on hemodynamics [91].  

          Treating calcium channel blocker (CCB) overdoses involves administering intravenous calcium, dopamine, and norepinephrine. High-dose insulin therapy can reduce mortality in cases of calcium channel blocker poisoning [60]. For severe shock or cardiac arrest resulting from these overdoses, extracorporeal life support is employed [60]. Case reports indicate that clinicians use lipid emulsion therapy to treat overdoses of amiodarone and flecainide [4] [92].

          Conclusion 

          Arrhythmias encompass a broad spectrum of heart rate and rhythm disturbances and present significant clinical challenges. Atrial fibrillation (AF) is the most prevalent arrhythmia, associated with increased morbidity, mortality, and healthcare costs [2][3]. Management involves antiarrhythmic drugs (AADs), which play a fundamental role despite their limitations and the potential for adverse effects.  

          Antiarrhythmic agents, classified by their primary action mechanism on the cardiac action potential, impact ionic channels or receptors, aiming to suppress arrhythmias [4]. The management objectives for arrhythmias include alleviating significant clinical symptoms and extending life.  

          Pharmacokinetic aspects, such as drug absorption, distribution, metabolism, and excretion, play crucial roles in the effectiveness and safety of AADs. Pharmacodynamics involves modifying the cardiac action potential and conduction velocity to prevent or terminate arrhythmias. Factors influencing drug efficacy include genetics, environmental conditions, and the patient's specific clinical profile. 

          Treatment of overdose with antiarrhythmic drugs requires immediate medical intervention, including antidotes and supportive measures like venoarterial extracorporeal membrane oxygenation (VA-ECMO) for severe cases. The management of specific drug toxicities, such as digoxin and beta-blockers, involves targeted therapies and supportive care to mitigate adverse effects and stabilize the patient's condition. 

          Antibiotic Use for UTI

          Introduction   

          A urinary tract infection (UTI) can develop in anyone but is more common in females than males. Approximately 40% of American women will develop a urinary tract infection in their lives [2]. Many UTIs can lead to serious health complications, including sepsis and sometimes patient mortality.  

          Thus, healthcare providers must be knowledgeable of the signs and symptoms of UTIs, the available antibiotics, and UTI treatment guidelines. Understanding the different pharmacokinetics of antibiotics used to treat UTIs is essential during drug selection. This course outlines UTI antibiotic pharmacology and addresses pharmacokinetics, including mechanism of action, side effects, usage, and contraindications.

          Definitions 

          This section covers the definitions related to UTI treatment and management. 

          Urinary Tract Infection 

          Bacterial infection of the lower urinary tract (usually confined to the bladder). This is also sometimes called cystitis and is primarily caused by the bacteria E. coli [2]. 

          Asymptomatic Bacteremia 

          A urine specimen is collected on a patient and shows the presence of bacteria, but they do not have any UTI symptoms [5]. 

          Pyelonephritis 

          Bacterial infection of the upper urinary tract (i.e. kidneys) [6]. 

          Urosepsis 

          When a urinary tract infection causes a systemic infection, also known as sepsis [6].

          Medications Overview 

          This section briefly reviews UTI antibiotic classes and medical indications. 

          Certain antibiotics are used to prevent or treat urinary tract infections and are used in both inpatient and outpatient settings. Healthcare providers should follow current guidelines regarding UTI treatment, which depends on the patient and type of urinary tract infection. UTI treatment algorithms are further divided into: 

          • Uncomplicated UTIs 
          • Complicated UTIs 
          • Prophylactic treatment for recurrent UTIs [6] 

          What constitutes uncomplicated UTIs are patients who have urinary symptoms, but do not have signs of systemic infections, like fever, flank pain, costovertebral angle (CVA) tenderness, etc. Patients can be male or female, unlike previous guidelines that categorized all males as complicated UTIs. Also, patients with uncomplicated UTIs usually have no underlying health conditions or risk factors that may affect treatment [6].  

          Conversely, complicated UTIs occur when patients have systemic symptoms. Patients who are pregnant, have a history of UTIs, or who are considered elderly also fall under complicated UTIs. Patients with pyelonephritis are automatically considered as having complicated UTIs as well. Patients with recurrent UTIs may be prescribed certain low-dose antibiotics for prevention [6]. 

          Regardless of the UTI type, below are some of the common antibiotics prescribed: 

          • Trimethoprim-sulfamethoxazole 
          • Nitrofurantoin

          Pharmacokinetics 

          This section discusses the pharmacokinetics of each antibiotic medication used to treat UTIs.  

          Trimethoprim-sulfamethoxazole 

          Sulfonamides, also called sulfa drugs, are a class of medications commonly used to treat bacterial infections, including UTIs. A common sulfonamide medication used to treat UTIs is sulfamethoxazole formulated with trimethoprim which is sometimes abbreviated as TMP-SMX, TMP-sulfa, or TMP-SMZ [22]. Trimethoprim-sulfamethoxazole is also approved by the Federal Drug Administration (FDA) to treat chronic bronchitis exacerbations, otitis media in children, and shigellosis. 

          This medication is also used for prevention and treatment of traveler’s diarrhea, toxoplasmosis, and Pneumocystis jirovecci and Pneumocystis carinii pneumonia. Some other off-label or non-FDA-approved uses are tuberculosis, malaria, listeria, pertussis, and community-acquired pneumonia [10]. 

          Since this a combination medication, TMP-SMX works by two different mechanisms of action. Trimethoprim competes with the enzyme dihydrofolate reductase and subsequently stops the production of tetrahydrofolate from converting to folate.  

          Sulfamethoxazole, a CYP2CP inhibitor, competes with p-aminobenzoic acid during dihydrofolate synthesis. These two medications combined work against folate production and block bacterial biosynthesis of nucleic acids and proteins. Both medications are metabolized by the liver [10]. 

          TMP-SMX is available via oral and intravenous (IV) forms. Adult TMP-SMX oral dosages are typically 160mg/800mg for the treatment of UTI, respectively, and dosages for children under 40 kilograms are weight-based. This medicaiton is best absorbed orally when taken with at least eight ounces of water. Intravenous TMP-SMX is given to hospitalized patients and dosages will vary. Some common side effects of trimethoprim-sulfamethoxazole include:  

          • Nausea and/or vomiting 
          • Rash and photosensitivity 
          • Dizziness 
          • Fatigue 
          • Loss of appetite and anorexia [10] 

          As this medication’s mechanism of action interferes with folate production, folate deficiency is also common. More severe side effects may include Stevens-Johnson syndrome, anemia, and Clostridioides difficile (C. diff) diarrhea. This medication should not be prescribed to patients with a sulfa allergy since it can cause anaphylaxis [10]. 

          Before prescribing this medication, healthcare providers should also be aware of the precautions and contraindications. Healthcare providers should be cautious when prescribing this medication to patients with decreased kidney function, as it can lead to toxicity and high potassium levels. Therefore, baseline and frequent monitoring of blood urea nitrogen (BUN), creatinine, and potassium levels are helpful.  

          Other contraindications include patients with liver failure, hematological disorders, or who are pregnant. TMP-SMX interferes with several medications, including phenytoin, digoxin, diuretics, and rifampin. Many of these medication interactions increase the risk for potential hyperkalemia, medication toxicity, and QT prolongation [10].

          Nitrofurantoin  

          Nitrofurantoin is another antibiotic commonly prescribed to treat urinary tract infections. This medication has been FDA-approved since 1953 to treat and prevent lower UTIs and is commonly considered a first-line treatment. Currently, nitrofurantoin has no other approved or off-label uses. It comes in two different forms, which are monohydrate and macrocrystalline [16]. 

          The mechanism of action for nitrofurantoin is not completely understood. However, it is thought to be absorbed by bacterial flavoproteins in the gastrointestinal tract and then further prevents bacterial enzymes from synthesizing DNA, RNA, and cell wall proteins [16]. 

          Nitrofurantoin is only available via the oral route. The dosage is usually 100 mg twice daily for UTI treatment and for UTI prophylaxis is 50mg to 100mg once daily. Common medication side effects include:  

          • Nausea and/or vomiting 
          • Diarrhea 
          • Loss of appetite [16] 

          Severe reactions, although rare, are pulmonary toxicity where patients may present with fever, chills, cough, and dyspnea. It may also cause liver toxicity, liver failure, and peripheral neuropathy. This medication is contraindicated in patients with a creatinine clearance of less than 60 mL/minute, hemolysis, or who have glucose-6-phosphate dehydrogenase (G6PD) deficiency [16]. 

          Healthcare providers should also be aware of considerations when prescribing nitrofurantoin. They must understand that nitrofurantoin should not be prescribed to patients with suspected or confirmed pyelonephritis, since it is only used to treat lower UTIs.  

          Nitrofurantoin should not be prescribed to people who are pregnant, especially between 38 to 42 weeks gestation, and neonates. It is also not recommended to give to patients who are 65 years or older due to increased potential adverse effects. For patients who take nitrofurantoin long-term for prophylactic use, liver function tests should be routinely completed and monitoring of pulmonary function [16].

          Fluoroquinolones 

          Fluoroquinolones are a class of antibiotics used to treat UTIs and other bacterial conditions. Examples of common fluoroquinolones include ciprofloxacin, moxifloxacin, and levofloxacin. However, ciprofloxacin is more commonly used to treat UTIs than the others and therefore, will be the medication reviewed in this section [19]. 

          In addition to urinary tract infections, ciprofloxacin is FDA-approved to treat various health conditions. Some common health conditions treated are gonorrhea, chancroids, joint infections, prostatitis, and some gastrointestinal infections. Ophthalmic forms are used to treat corneal ulcers and conjunctivitis, while otic forms may be used in otitis externa [17]. 

          Ciprofloxacin’s mechanism of action is considered bactericidal since it works by inhibiting bacterial DNA replication. It acts against DNA topoisomerase and DNA gyrase to hinder DNA replication. Ciprofloxacin is most effective against gram-negative bacteria, but also some gram-positive bacteria. Due to mutations in the DNA gyrase, ciprofloxacin and other fluoroquinolones have begun to show bacterial resistance over the past several years [17]. 

          Ciprofloxacin comes in many forms, including oral, IV, ophthalmic, and otic. For the treatment of UTI, this medication is available via oral and IV forms. Recommended dosages are dependent on the severity of UTI and route. Oral dosages for UTI treatment range from 250mg to 500mg twice daily, while IV dosages can range from 200mg to 400mg twice daily to upwards of 400mg every eight hours. Regardless of the administration route, common side effects are nausea and diarrhea. Some serious adverse effects include: 

          • QT prolongation 
          • Hypoglycemia 
          • Hyperglycemia 
          • Photosensitivity [17] 

          Ciprofloxacin has an FDA black box warning of tendinitis and tendon rupture, peripheral neuropathy, and myasthenia gravis exacerbation. Due to the effects this medication has on tendons, Achilles tendon rupture, aortic aneurysm, and aortic dissection are also serious adverse effects. If the healthcare provider suspects any adverse effects, including mild tendonitis, the medication should be discontinued immediately.  

          Furthermore, when prescribing ciprofloxacin, there are additional considerations and contraindications. As with all medications, ciprofloxacin should not be prescribed to patients with a known allergy to this medication. 

          Ciprofloxacin should not be prescribed along with tizanidine, theophylline, or cyclosporine due to interactions. Antacids can also interfere with the absorption of ciprofloxacin and ciprofloxacin toxicity is more likely in older adults. Healthcare providers should encourage patients with diabetes to closely monitor their blood glucose levels at home since this medication can cause hypo- or hyperglycemia [17].

          Beta-lactams 

          Beta-lactams are a class of antibiotics used to treat various bacterial conditions, including UTIs. The three main beta-lactams covered below are those commonly used to treat UTI and include cephalexin, amoxicillin-clavulanate, and ceftriaxone. Other beta-lactams that are approved for UTI treatment are cefpodoxime, cefdinir, and cefadroxil, and work similarly to others in this medication family. 

          Cephalexin 

          Cephalexin is a beta-lactam antibiotic that is classified as a first-generation cephalosporin. It was initially approved by the FDA in 1970 and is widely used throughout healthcare settings. In addition to acute and chronic UTIs, cephalexin is approved to treat upper and lower respiratory infections, bone infections, and otitis media. It is also used to treat surgical site, skin, and soft tissue infections [8]. 

          Cephalexin falls under the beta-lactam class since its structure has a beta-lactam ring. This ring inhibits the synthesis of peptidoglycan which further disrupts the bacterial cell wall. More specifically, the beta-lactam ring binds to the penicillin-binding proteins during peptidoglycan synthesis, causing the disruption of the bacterial cell wall and viability [8]. 

          Cephalexin is only available via oral route and can be prescribed in tablet, capsule, and suspension forms. Daily dosages from 1000mg to 4000mg for adults and for children, are weight-based and range from 25mg to 100mg per kilogram per day. Some side effects of cephalexin include: 

          • Abdominal pain 
          • Diarrhea 
          • Nausea and/or vomiting 
          • Rash 
          • Candidiasis [8] 

          Other reactions may include increased liver enzymes, C. diff colitis, and hemolytic anemia. Although cross-reactivity with penicillin is somewhat uncommon, healthcare providers should use caution when prescribing this medication to patients who are allergic to penicillin. Furthermore, it should not be prescribed to patients with a cephalosporin allergy. Cephalexin also interacts with metformin, causing decreased clearance of metformin from the body.  

          If a patient is taking metformin, they should be advised to closely monitor their blood glucose levels since the risk for hypoglycemia is increased. Healthcare providers should also be cautious when prescribing this medication to patients who are taking probenecid. Cephalexin can also increase prothrombin time, which typically requires monitoring, especially for those undergoing anticoagulant treatment [8].

          Amoxicillin-clavulanate 

          As its name implies, amoxicillin-clavulanate is a combination medication of amoxicillin and clavulanic acid. In addition to treating UTIs, this medication is FDA-approved to treat rhinosinusitis, acute otitis media, skin infections, and aspiration and community-acquired pneumonia. Other non FDA-approved uses are impetigo, chronic obstructive pulmonary disease exacerbations, diabetic foot infections, and human and animal bites [4]. 

          Amoxicillin-clavulanate works via two different mechanisms of action since it is a combination medication. The amoxicillin component is a beta-lactam antibiotic and works via the same mechanism as cephalexin described above. Clavulanic acid is a beta-lactamase inhibitor, which prevents bacteria from destroying beta-lactam antibiotics. Thus, the reason why clavulanic acid is often combined with amoxicillin [4]. 

          This medication is only available via oral forms, such as suspensions, chewable, immediate-release, or extended-release tablets. Dosages are dependent on the underlying condition being treated, medication form (i.e. immediate- versus extended-release), and the patient’s age. Regardless of dosage, amoxicillin-clavulanate can lead to common gastrointestinal side effects, such as: 

          • Diarrhea 
          • Nausea 
          • Vomiting 
          • Loose stools [4] 

          Vaginal candidiasis is another common side effect of amoxicillin-clavulanate. For patients who are breastfeeding, this medication may cause hypersensitivity reactions in infants since it is excreted in breast milk. Additionally, amoxicillin-clavulanate has several drug interactions with medications, including probenecid, oral anticoagulants, allopurinol, and oral contraceptives. For patients on hemodialysis or with severe renal impairment, usually where their creatinine clearance is less than 30 mL/min, dose adjustments are recommended.  

          Healthcare providers should monitor patients’ liver enzymes for possible hepatic impairment, and if hepatic injury occurs, stop the medication immediately and follow treatment recommendations accordingly. Since amoxicillin is a penicillin derivative, it should not be prescribed to individuals with a penicillin allergy [4].

          Ceftriaxone 

          Ceftriaxone is another beta-lactam antibiotic used to treat UTIs and is usually an adjunct medication. It is a third-generation cephalosporin that is also used to treat gonorrhea, pelvic inflammatory disease, meningitis, and certain abdominal, respiratory, and joint infections. Additionally, ceftriaxone treats bacteremia, sepsis, and infective endocarditis. Since ceftriaxone belongs to the beta-lactam class, its mechanism of action is the same as previously described cephalexin [18]. 

          Ceftriaxone comes in both intravenous and intramuscular (IM) forms since it is not absorbed through the gastrointestinal tract. For UTI treatment, the dosage for adults is 1 to 2 grams IV or IM every 24 hours. In an outpatient setting, ceftriaxone is often given as a single IM dose to patients with pyelonephritis who are not hospitalized. Again, this medication is used as an adjunct medication, so it is given as a single IM dose, followed by another oral antibiotic for UTI treatment. Dosages for children range from 50mg to 75mg per kilogram per day for both IM and IV forms [18]. Some common side effects of ceftriaxone are: 

          • Diarrhea 
          • Nausea  
          • Vomiting 
          • Dysgeusia (metallic or foul taste in the mouth) 
          • Injection site reaction, especially for IM [18] 

          Other adverse effects associated with ceftriaxone are hemolytic anemias, neutropenia, and thrombocytosis. It should also be noted that this medication can cause neurological symptoms, cholelithiasis, jaundice, elevated liver enzymes, and pancreatitis [18]. 

          Healthcare providers should also review ceftriaxone’s precautions and contraindications. This medication is cross-reactive with penicillin and can cause a hypersensitivity reaction. Furthermore, it should not be prescribed to patients with a cephalosporin allergy. If ceftriaxone is administered through an IV, it must not be mixed with calcium-containing IV solutions or products. Other possible medication interactions are estradiol, cyclosporine, and bumetanide. For patients with liver or kidney impairment, dosages must be adjusted and should not exceed 2 grams per day [18].

          Cefdinir 

          Cefdinir is another beta-lactam antibiotic used to treat UTIs and is also a third-generation cephalosporin. In addition to UTI treatment, cefdinir is approved for the treatment of pneumonia, bacterial infections involving the skin, and respiratory infections of the ears, throat, and sinuses. As cefdinir is a third-generation cephalosporin, its mechanism of action is the same as previously described ceftriaxone. Thus, it interferes with bacterial cell wall synthesis [13]. 

          Cefdinir is only available via oral route by either capsule or liquid suspension. Treatment dosages and duration are dependent on the underlying condition it is being used to treat [13]. For UTI, this medication is usually prescribed at 300mg twice daily for 5 to 7 days. However, this course may be extended for patients with pyelonephritis or complicated UTIs. Some common side effects of this medication include: 

          • Nausea and vomiting 
          • Diarrhea 
          • Vaginal itching 
          • Red-tinged stools [13] 

          Other more serious side effects may include rash, hives, facial swelling, and difficulty breathing or swallowing. As with all medications, healthcare providers should be aware of this medication’s precautions and contraindications. Cefdinir should not be prescribed to patients with a cephalosporin allergy or who are taking probenecid. It should also be avoided in patients with gastrointestinal diseases, like colitis, and kidney disease. This medication should be taken at least two hours apart from any aluminum, magnesium, or iron supplement. Additionally, healthcare providers should avoid prescribing the oral suspension form to patients with diabetes, since it contains high amounts of sucrose and can potentially raise blood sugar levels [13].

          Other Antibiotics Used to Treat UTI 

          This section reviews other antibiotics used to treat urinary tract infections. Two common additional antibiotics administered in an inpatient setting include piperacillin-tazobactam and antipseudomonal carbapenems, such as imipenem or meropenem. These are usually reserved for patients with at least one risk factor for multidrug-resistant gram-negative organisms [7]. Drug information about meropenem will be discussed in greater detail below. Other less common antibiotics available in the outpatient are fosfomycin and pivmecillinam. Although these medicatios are used less commonly, it is still important to understand their pharmacokinetics.  

          Piperacillin-tazobactam 

          As mentioned, piperacillin-tazobactam is used to treat multidrug-resistant gram-negative UTIs in an inpatient setting. In addition to treating UTIs, it is approved for the treatment of skin, gynecological, and certain abdominal infections. This medication is a combination of piperacillin (a penicillin antibiotic) and tazobactam (a beta-lactamase inhibitor). Therefore, its mechanism of action is that of both the penicillin and beta-lactam classes as previously described [15]. 

          Piperacillin-tazobactam is available in IV form and the dosage is usually 3.375 grams every six hours [7]. Like many antibiotics, some common side effects include: 

          • Diarrhea 
          • Nausea and/or vomiting 
          • Stomach pain [15] 

          This medication can also cause mouth sores, sleeping difficulties, and in more severe cases, itching, difficulty swallowing, and wheezing. Piperacillin-tazobactam should not be prescribed to patients who are taking other penicillin or beta-lactam antibiotics or who have an allergy. It interferes with certain medications including, aminoglycosides, anticoagulants, methotrexate, and vancomycin. Additionally, for patients with diabetes, this medication can cause false results with certain glucose tests [15].

          Meropenem 

          An antipseudomonal carbapenem, meropenem, is used to treat inpatient multidrug-resistant gram-negative UTIs. Meropenem is also approved for the treatment of pneumonia, intra-abdominal infections, peritonitis, and meningitis [21]. 

          This medication’s mechanism of action is similar to beta-lactams, as it falls under the same family of antibiotics. It binds to penicillin-binding proteins and inhibits bacterial cell wall synthesis by inhibiting peptidoglycan [21]. 

          Meropenem is only available in IV form and dosages are dependent on the condition being treated. For UTIs, 1 gram is administered every 8 hours. Gastrointestinal side effects are common for this medication and include symptoms like diarrhea, nausea, vomiting, and constipation. Additional adverse effects may include: 

          • Drowsiness 
          • Headache 
          • Insomnia 
          • Depression [21] 

          Seizures are also a potential adverse effect, and therefore, healthcare providers must monitor patients for neurological symptoms. Agranulocytosis, thrombocytopenia, gastrointestinal bleeding, and hemolytic anemia are other conditions which have been reported when taking this medication. For patients with renal impairment, the dosage will need to be adjusted. Meropenem also has many medication interactions, with some major ones including afatinib, atogepant, cariprazine, and colchicine [21].

          Fosfomycin 

          Fosfomycin is an antibiotic that is FDA-approved to treat uncomplicated urinary tract infections and is considered a first-line treatment option. In the United States, fosfomycin is only available in oral, powder which is mixed and dissolved in liquid. Furthermore, although this medication is a first-line UTI treatment option, it is not widely available in the United States [20]. 

          This medication’s mechanism of action works by interfering with the formation of peptidoglycan precursor UDP N-acetylmuramic acid, also known as UDP-MurNAc. As it acts one step prior to the beta-lactam antibiotic family, Fosfomycin enters the bacteria through the transporter systems L-alpha-glycerophosphate and hexose-6-phosphate. This medication also reduces the ability of bacteria to adhere to the epithelial cells of the urinary tract [9]. 

          To treat UTI, a single dose of 3 grams of fosfomycin is given, which is added to about 3 to 4 ounces of cold water to dissolve the medication. Common side effects may include: 

          • Nausea 
          • Diarrhea 
          • Headache 
          • Back pain [14] 

          Other serious side effects are joint pain, rash, facial or oral swelling, and jaundice. Healthcare providers should review this medication’s interactions and contraindications. Fosfomycin interacts with medications like cisapride, metoclopramide, and certain vitamins. Healthcare providers should use caution when prescribing to patients with a history of asthma, liver disease, or who are pregnant or breastfeeding [14].

          Pivmecillinam 

          Pivmecillinam is another antibiotic used to treat lower urinary tract infections and is part of the UTI treatment algorithm. However, the FDA has not approved this medication for use in the United States [11]. Therefore, most of the specific drug information is not available.  

           

           

          Considerations for Prescribers 

          This section reviews potential considerations when prescribing antibiotics for UTIs. 

          Healthcare providers must consider and review several factors when prescribing antibiotics for UTI treatment. First, the medication’s route, dosage, and treatment duration are usually determined by the setting (inpatient versus outpatient), the type of UTI (e.g. empirical, asymptomatic bacteremia, uncomplicated, complicated, or prophylaxis), and the patient’s underlying medical conditions and risk factors. Furthermore, healthcare providers should strive to follow current treatment guidelines, approved uses, and their organization’s protocols when initiating or adjusting these medications. Healthcare providers must review the patient’s medical history, recent lab values, contraindications, and potential side effects.  

          Patient Population 

          Certain classes of antibiotics should be avoided in specific individuals or patient populations, and thus, healthcare providers must be aware of these precautions, contraindications, and black box warnings. Ciprofloxacin can lead to medication toxicity and hypoglycemia in older adults and must be avoided in this patient population when able [17]. Additionally, prescribing medications, such as TMP-SMZ and cephalexin, should be cautioned in patients with renal impairment [8, 10]. Prescribing nitrofurantoin, TMP-SMZ, cephalexin, and ceftriaxone should be cautioned in patients with liver failure or elevated liver enzymes. Healthcare providers should routinely monitor the patient’s liver enzymes and function tests [8, 10, 16, 18].  

          The patient’s gender at birth plays another large factor in antibiotic selection since treatment for males is considered a complicated UTI and antibiotic duration is extended. Furthermore, in patients who are pregnant or breastfeeding, certain antibiotics should not be prescribed, with some including TMP-SMZ and fluoroquinolones. Alternative treatments for patients who are pregnant are amoxicillin-clavulanate or [6]. For patients with chronic UTIs, initial prophylactic treatment should be started for 3 months and then reevaluated thereafter for prevention. Typical low-dose prophylactic antibiotics are TMP-SMX and nitrofurantoin. However, the healthcare provider should strongly consider medication compliance and potential antibiotic resistance [1].  

          Allergies 

          Healthcare providers should also review the patient’s allergies and cross-reactivity of certain antibiotics. Trimethoprim-sulfamethoxazole should not be prescribed to individuals with a sulfa allergy. Furthermore, healthcare providers should not prescribe patients with a penicillin allergy amoxicillin-clavulanate and should use caution when prescribing these individuals beta-lactams or cephalosporins due to their potential cross-reactivity, although the percentage is low [8, 10]. 

          Medication History 

          As discussed, certain antibiotics interact with specific medications. Healthcare providers must review the patient’s medication list prior to prescribing antibiotics. For instance, amoxicillin-clavulanate interacts with allopurinol and lessens the effectiveness of oral contraceptives. Patients on oral contraceptives should be instructed to use backup birth control methods while on the antibiotic [4]. Additionally, while interactions may exist medication timing plays an important role. For example, medications such as ciprofloxacin and TMP-SMZ interact with antacids. However, if the antibiotic is taken two hours before or six hours after the antacid, a potential medication interaction is less likely [17]. Cephalexin is better absorbed on an empty stomach while other antibiotics are recommended to be taken with food [8].  

          Bacterial Sensitivity 

          Some antibiotics do not treat certain strains of bacteria and thus, healthcare providers must be judicious about initial antibiotic selection and following up with the patient about their urine culture results. For example, bacterial growth on the urine culture might not be sensitive to the initial antibiotic prescribed and may be resistant. Therefore, the antibiotic may need to be changed or dual therapy may be needed.  

          Also, patients with recurrent UTIs sometimes develop antibiotic resistance to first-line medications for the treatment of UTI, so an alternative medication should be initially prescribed, and a urine culture sent. If the patient is treated frequently for UTIs, then a referral to urology is warranted for further evaluation [6]. In some patients, asymptomatic bacteremia is found on a routine urinalysis completed during an annual comprehensive exam. Healthcare providers should review the current screening and treatment guidelines on asymptomatic bacteria in adults. For most patients, a urine culture should be sent for further evaluation, and antibiotic administration delayed until the culture has resulted [5]. 

          Patient Education 

          Patients should be instructed on potential medication side effects and signs of adverse reactions. In an outpatient setting, healthcare providers must instruct patients on worsening symptoms and when to seek immediate or emergent treatment. Oftentimes, urinary tract infections move upstream into the kidneys and cause pyelonephritis or urosepsis [6].

          Ask yourself...

          1. What factors should healthcare providers consider when prescribing antibiotics? 
          2. Which antibiotic can be prescribed during pregnancy? 
          3. Which steps should be taken for patients with recurrent UTIs? 
          4. What health conditions and lab values are important when selecting UTI antibiotics? 

          Upcoming Research 

          This section reviews upcoming research and medications for UTI treatment. 

          The bacteria strain, E. coli, is typically responsible for urinary tract infections. However, this is not the case for all UTIs, and some patients have developed multiple drug-resistant organisms due to recurrent infections. Therefore, there is much research needed on UTI antibiotic treatment to eradicate these organisms. Recent development of immunomodulatory therapy has been considered as well as medications that inhibit bacterial adhesions to the epithelial cells of the urinary tract. Vaccinations against UTI have also shown recent promise, but further research is still needed [3]. Other non-antibiotic therapies are also being researched, like Lactobacillus-containing products (i.e. probiotics) and cranberry supplements [12].

          2. What new research is there about antibiotics for UTI treatment? 
          3. Which types of new products are being researched about UTI treatment? 

          Conclusion 

          As discussed, antibiotic selection for the treatment of urinary tract infections depends on a variety of factors. Healthcare providers should understand the pharmacokinetics, potential side effects, interactions, and contraindications when selecting an antibiotic. They should also follow current clinical guidelines and their facility’s protocols for a more evidence-based approach. Furthermore, ordering a urine culture or referring a patient to a urologist is warranted for patients with recurrent urinary tract infections.
