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.
Dexamethasone is a potent glucocorticoid that binds to glucocorticoid receptors, modulating gene expression to inhibit pro-inflammatory cytokines (e.g., IL-1, IL-6, TNF-α) and reduce inflammation, immune response, and adrenal function.
Intralesional injection: 2.5-5 mg per lesion, repeated every 1-2 weeks. Topical: Apply thin film to affected area 2-4 times daily.
0.75 mg orally once daily, typically as part of a tapering regimen for anti-inflammatory or immunosuppressive effects.

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: 36-54 hours in adults with normal renal function; prolonged to 72-168 hours in severe renal impairment.
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
Renal: ~65-80% as unchanged drug; Fecal: ~10-15% as metabolites; Minor biliary excretion.
