ANDRODERM vs DANOCRINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Testosterone is an androgen receptor agonist; it binds to androgen receptors, leading to changes in gene expression that promote male secondary sexual characteristics and maintain libido, muscle mass, and bone density.
Danazol is a synthetic androgen derived from ethisterone. It suppresses the pituitary-ovarian axis by inhibiting gonadotropin (LH and FSH) release, leading to anovulation and amenorrhea. It also binds to androgen, progesterone, and glucocorticoid receptors, exerting weak androgenic, antiestrogenic, and antigonadotropic effects. Additionally, it may directly inhibit ovarian steroidogenesis and increase clearance of endogenous sex hormones.
Apply one 2.5 mg or 5 mg transdermal system to clean, dry, intact skin on the abdomen, upper arms, or thighs once daily, preferably in the morning. Starting dose is 5 mg daily; adjust based on serum testosterone levels.
100-200 mg orally twice daily for endometriosis; 200-400 mg twice daily for fibrocystic breast disease; 200 mg twice daily for hereditary angioedema. Maximum dose: 800 mg/day.

Terminal elimination half-life is approximately 10–100 minutes (rapid), but due to transdermal absorption, effective half-life is extended to about 8–10 hours after patch application.
Terminal elimination half-life: 10–30 hours (mean 15 hours); clinically, steady-state reached after 2–4 days.
Approximately 90% of testosterone metabolites are excreted in urine as glucuronide and sulfate conjugates; 6% are excreted in feces via bile.
Renal (metabolites, ~50%), biliary/fecal (~30%), unchanged drug minimal.
