What this research studies

This research investigates how hormone therapy, particularly estradiol, influences the metabolism and transport of medications in transgender and gender diverse adults. The study will utilize a framework involving probe substrates and biomarkers to assess changes in drug handling proteins before and during hormone treatment. By understanding these interactions, the research aims to improve drug safety and efficacy for individuals undergoing hormone therapy. Participants will contribute to advancing clinical strategies that address potential drug interactions and optimize treatment outcomes.

Who could benefit from this research

Good fit: Ideal candidates for this research are transgender and gender diverse adults who are receiving or considering hormone therapy.

Not a fit: Patients who are not undergoing hormone therapy or who are not transgender or gender diverse may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to safer and more effective medication regimens for transgender adults undergoing hormone therapy.

How similar studies have performed: Other research has shown promising results in understanding drug interactions in transgender populations, making this approach both relevant and necessary.
