ARISTOGEL vs DEXAIR
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.
DEXAIR (dexamethasone) is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (e.g., cytokines, prostaglandins). It also inhibits leukocyte infiltration and reduces capillary permeability.
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.
Inhalation: 2 inhalations (80 mcg each) twice daily, maximum 640 mcg/day.

Terminal elimination half-life is 12 hours. Given dosing frequency, steady-state achieved within 2 days; accumulation minimal with standard dosing.
Terminal elimination half-life: 3.0-4.5 hours in adults with normal renal function; prolonged to 8-12 hours in severe renal impairment (CrCl <30 mL/min).
Primarily renal (80%) as unchanged drug; 20% fecal via biliary elimination.
Renal (urinary): ~65-75% as unchanged drug and metabolites; biliary/fecal: ~20-30% as metabolites; less than 10% unchanged in bile.
