ANDROGEL vs FLUOXYMESTERONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Androgen receptor agonist; testosterone replacement therapy to restore serum testosterone to physiologic levels.
Synthetic androgen receptor agonist; binds to androgen receptors, modulating gene expression and promoting protein synthesis, muscle growth, and secondary sexual characteristic development.
50 mg (5 g gel) applied topically once daily, preferably in the morning. Dose may be adjusted between 25 mg (2.5 g gel) and 100 mg (10 g gel) based on serum testosterone levels.
Adults: 5-20 mg orally once daily. For replacement therapy, 5-10 mg daily; for hypogonadism, 5-20 mg daily for several months.

The terminal elimination half-life of testosterone from AndroGel is approximately 10-12 hours when applied topically, but due to continuous absorption from the skin depot, serum levels are sustained over 24 hours, allowing once-daily dosing.
Clinical Note
moderateAcarbose + Fluoxymesterone
"Acarbose may increase the hypoglycemic activities of Fluoxymesterone."
Clinical Note
moderateSunitinib + Fluoxymesterone
"Sunitinib may increase the hypoglycemic activities of Fluoxymesterone."
Clinical Note
moderatePrednisolone + Fluoxymesterone
"Prednisolone may increase the fluid retaining activities of Fluoxymesterone."
Clinical Note
moderateDexamethasone + Fluoxymesterone
Terminal elimination half-life: 9.2 hours; clinical context: supports once-daily dosing for androgen replacement, with steady-state achieved in ~2 days
Approximately 90% of a topical dose is excreted in urine as conjugated and unconjugated metabolites, with about 6% excreted in feces via bile; renal elimination is the primary route.
Renal: 90% as glucuronide and sulfate conjugates; fecal: 10%
