09 Feb EFFECT OF TESTOSTERONE TREATMENT ON DRUG METABOLISM AND TRANSPORT

Your gender-affirming hormone therapy contains testosterone, a hormone that your body creates and uses naturally. Testosterone is prepared as a medication that you can take to increase your hormone levels. Changes in testosterone levels in your body may affect how your body processes certain medicines. The purpose of this study is to find out how testosterone therapy affects a single tracer dose of approved medicines in your blood (midazolam, digoxin, and acetaminophen) and to confirm testosterone treatment does not affect natural bacterial in your gut.
