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.
Corticosteroid with anti-inflammatory and immunosuppressive properties; suppresses inflammatory cytokines and immune cell activity.
Intralesional injection: 2.5-5 mg per lesion, repeated every 1-2 weeks. Topical: Apply thin film to affected area 2-4 times daily.
IV or IM: 10-40 mg methylprednisolone (as sodium succinate) every 4-6 hours; high-dose pulse therapy: 30 mg/kg IV over 30-60 minutes every 4-6 hours for 48-72 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: 2.5–3.5 hours. In clinical context, the biologic half-life (suppression of HPA axis) is longer (24–36 hours) due to tissue retention of active metabolites.
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
Renal: approximately 80% as metabolites (glucuronide and sulfate conjugates) and unchanged drug; biliary/fecal: less than 5%.
