Pharmacotherapy Considerations in the Management of Transgender Patients: An Alternative Viewpoint

Drug Interactions with Gender-Affirming Hormone Therapy: Focus on Antiretrovirals and Direct Acting Antivirals

INTRODUCTION

Gender-affirming care may include hormonal therapy to attain desired health outcomes in transgender (trans) individuals. To provide safe, affirming medical care for trans patients, health care providers must identify and manage drug-drug interactions (DDIs) between gender affirming hormonal therapy (GAHT) and other medication therapies.

AREAS COVERED

This review summarizes available data on DDIs between GAHT and antiretrovirals (ARVs) or hepatitis C direct acting antivirals (DAAs). Potential pharmacokinetic and pharmacodynamic DDIs are predicted based on GAHT, ARV, and DAA pharmacology and adverse event profiles. Clinical management strategies are discussed.

EXPERT OPINION

GAHT may be involved in pharmacokinetic and/or pharmacodynamic DDIs. Certain ARV classes (non-nucleoside reverse transcriptase inhibitors, protease inhibitors) may alter GAHT disposition, whereas selected ARVs (unboosted integrase inhibitors, doravirine, or rilpivirine) may have less impact on GAHT. DAAs may interact with GAHT, but the clinical relevance is unclear. ARV- and/or DAA-associated side effects (including depression, cardiovascular disease, hyperlipidemia) are important to consider in the clinical management of trans patients. Clinicians must evaluate potential DDIs and overlapping side effects between ARVs, DAAs and GAHT when providing care for trans patients.

Faculty insights regarding incorporation of gender- and sex-related differences in the PharmD curriculum: Phase 2

BACKGROUND

While pharmacists should be aware of gender and sex-related differences in treatment related decisions, this is not a required doctor of pharmacy curricular component. A regional pilot study demonstrated that approximately half of pharmacy practice faculty discussed these differences in their content area. The aim of this study was to evaluate the extent of inclusion of gender and sex-related differences on a national level in doctor of pharmacy curricula and to determine if faculty are comfortable teaching the topic.

METHODS

An electronic message with a link to an online survey was distributed to 7250 faculty members at 139 colleges of pharmacy. The survey remained open for three weeks and potential participants received weekly email reminders. The survey was voluntary, and responses were de-identified.

RESULTS

Overall, 641 faculty participated in the survey (8.8% response rate). Most respondents indicated that they do not teach about gender or sex-related differences (54.9%). Of those faculty reporting teaching gender and/or sex-related differences, 28% indicated that it was addressed in one clinical topic, while some (7.7%) indicated that the content was included in up to five topics. Half of faculty (53.6%) indicated that they believe this topic is somewhat important.

CONCLUSIONS

Results of this study suggest that gender and sex-related differences are not adequately addressed in current pharmacy curricula.

Disease screening and prevention for transgender and gender-diverse adults

Primary care clinicians have an important role in the health and wellness of transgender and gender-diverse (TGD) adults and need to know best practices of health maintenance and disease prevention interventions. This article focuses on how exogenous use of sex steroids provided as hormone therapy and gender-affirming procedures affect screening and prevention. Hormone therapy can affect the heart, liver, lipids, bones, brain, skin, and reproductive organs; likewise, behaviors and gender-affirming procedures may alter the risks, prevalence, and screening techniques of sexually transmitted infections. Where applicable, modifications accounting for those differences should be incorporated into the primary care of TGD adults.
