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.
Glucocorticoid receptor agonist; modulates gene expression to suppress inflammation, immune response, and reduce capillary permeability.
Intralesional injection: 2.5-5 mg per lesion, repeated every 1-2 weeks. Topical: Apply thin film to affected area 2-4 times daily.
0.5-9 mg/day IV or IM in divided doses every 12-24 hours; acute conditions may require 4-8 mg IV initially.

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: 5-6 hours (plasma); biological half-life (HPA axis suppression): 24-36 hours.
Renal: 75% as metabolites (primarily conjugated), 15% as unchanged drug. Biliary/fecal: 10%.
Renal: 90-95% as inactive metabolites; biliary/fecal: <5%.
