ARISTOCORT A vs BETAMETHASONE DIPROPIONATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Triamcinolone acetonide is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, suppress cytokine production, and decrease inflammation and immune responses.
Betamethasone dipropionate is a glucocorticoid receptor agonist that binds to cytosolic glucocorticoid receptors, leading to modulation of gene transcription. It suppresses pro-inflammatory cytokines (e.g., IL-1, IL-2, TNF-α), inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, and stabilizes mast cells.
Intralesional injection: 2.5-5 mg per lesion, repeated every 1-2 weeks. Topical: Apply thin film to affected area 2-4 times daily.
Apply topically as 0.05% cream, ointment, or lotion to affected area once or twice daily. Maximum: 45 g/week.

Terminal half-life: 2-3 hours for triamcinolone acetonide. Clinical context: Duration of action longer due to receptor binding and intracellular activity; anti-inflammatory effects persist 24-48 hours after IM administration.
Terminal elimination half-life: 6-8 hours (parenteral); clinically, duration of adrenal suppression may extend beyond this.
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
Renal, ~75% as conjugated metabolites; biliary/fecal, ~25%.
