ARISTOGEL vs DEXACORT
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 modulates gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
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.
Oral: 0.75-9 mg/day in divided doses; IV: 0.5-9 mg/day every 6-12 hours; IM: 4-20 mg every 2 weeks.

Terminal elimination half-life is 12 hours. Given dosing frequency, steady-state achieved within 2 days; accumulation minimal with standard dosing.
Plasma terminal elimination half-life is 2.8-3.5 hours in adults, but the biological half-life (duration of HPA axis suppression) is 24-36 hours due to prolonged receptor occupancy
Primarily renal (80%) as unchanged drug; 20% fecal via biliary elimination.
Renal (approximately 80% as inactive metabolites, <5% unchanged), biliary/fecal (minor, approximately 15-20%)
