AXIRON vs FLUOXYMESTERONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Testosterone replacement therapy; binds to androgen receptors, modulating gene expression and promoting protein synthesis, muscle growth, and secondary sexual characteristics.
Synthetic androgen receptor agonist; binds to androgen receptors, modulating gene expression and promoting protein synthesis, muscle growth, and secondary sexual characteristic development.
One or two pump actuations (30 mg per actuation) applied to the axilla once daily; dose range 30-90 mg daily.
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 is approximately 10-100 minutes after intravenous injection, but for Axiron (testosterone topical solution), the apparent half-life is about 1-2 hours due to continued absorption from the skin and distribution/elimination. Clinically, steady state is achieved after about 2 weeks of daily application.
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
Testosterone is primarily excreted in urine as glucuronide and sulfate conjugates (about 90%) and about 6% in feces via bile. Approximately 90% of a dose is excreted in urine, with the remainder in feces.
Renal: 90% as glucuronide and sulfate conjugates; fecal: 10%
