Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; modulates gene expression to suppress inflammation, immune response, and reduce capillary permeability.
Corticosteroid with anti-inflammatory, immunosuppressive, and antiproliferative properties; suppresses cytokine production, inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, and stabilizes lysosomal membranes.
0.5-9 mg/day IV or IM in divided doses every 12-24 hours; acute conditions may require 4-8 mg IV initially.
Intra-articular injection: 10-40 mg for large joints, 5-15 mg for medium joints, 2.5-5 mg for small joints. Intralesional injection: 2.5-5 mg per lesion. Intramuscular injection: 40-80 mg once monthly. Not for IV or subcutaneous use.

Terminal elimination half-life: 5-6 hours (plasma); biological half-life (HPA axis suppression): 24-36 hours.
Terminal elimination half-life is approximately 2 to 3 hours after IV administration, but due to the triamcinolone acetonide suspension formulation, the effective half-life following intramuscular or intra-articular administration is prolonged to 2-3 weeks due to slow dissolution from the injection site.
Renal: 90-95% as inactive metabolites; biliary/fecal: <5%.
Primarily hepatic metabolism followed by renal excretion of inactive metabolites. Less than 5% excreted unchanged in urine. Biliary/fecal elimination accounts for approximately 15-20% of total clearance.
