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.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and subsequent anti-inflammatory and immunosuppressive effects. It inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses cytokine production.
Intralesional injection: 2.5-5 mg per lesion, repeated every 1-2 weeks. Topical: Apply thin film to affected area 2-4 times daily.
10-60 mg orally once daily or divided twice daily; maximum 60 mg/day.

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: 2-3 hours (after IV/IM/oral). Clinically, anti-inflammatory effects persist beyond plasma half-life due to glucocorticoid receptor-mediated gene transcription effects.
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
Primarily renal (80-90% as inactive glucuronide and sulfate conjugates; less than 10% as unchanged drug). Biliary/fecal excretion accounts for about 5%.
