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.
Synthetic corticosteroid with potent glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression to suppress 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.
100 mg intravenously every 8 hours for 24 hours, then 50 mg intravenously every 8 hours for 48 hours, followed by 25 mg intravenously every 8 hours for 72 hours.

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 is 2.5–3.5 hours; clinically, this short half-life requires multiple daily dosing for sustained effects.
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
Primarily renal (80% as metabolites, 20% unchanged); minor biliary/fecal (<5%).
