ARISTOGEL vs DEXACEN-4
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Testosterone replacement therapy; binds to androgen receptors, activating gene transcription and increasing protein synthesis.
Dexamethasone is a glucocorticoid receptor agonist that binds to the glucocorticoid receptor, leading to increased transcription of anti-inflammatory proteins and suppression of pro-inflammatory mediators.
Aristogel is a topical gel containing 1% testosterone. The recommended adult dose is 5 g (50 mg testosterone) applied once daily to clean, dry, intact skin of shoulders, upper arms, and/or abdomen. Apply at approximately the same time each day, preferably in the morning.
Dexamethasone 4 mg orally or intravenously every 6-8 hours; typical adult dose is 4-20 mg/day in divided doses, depending on condition.

Terminal elimination half-life is 12 hours. Given dosing frequency, steady-state achieved within 2 days; accumulation minimal with standard dosing.
3-4 hours; prolonged to 6-8 hours in renal impairment (CrCl <30 mL/min)
Primarily renal (80%) as unchanged drug; 20% fecal via biliary elimination.
Renal: 65-80% as unchanged drug; Biliary: 10-15% as metabolites; Fecal: <5%
