Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators such as cytokines, prostaglandins, and leukotrienes. It also induces lipocortin synthesis, inhibits phospholipase A2, and reduces immune cell activity.
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.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
Intralesional injection: 2.5-5 mg per lesion, repeated every 1-2 weeks. Topical: Apply thin film to affected area 2-4 times daily.

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
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.
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
