Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory, immunosuppressive, and antiproliferative properties; suppresses cytokine production, inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, and stabilizes lysosomal membranes.
Corticosteroid that binds to glucocorticoid receptors, leading to modulation of gene expression and suppression of inflammatory mediators (e.g., prostaglandins, leukotrienes) and immune cell activity.
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.
20-60 mg intramuscularly or intra-articularly once daily as a single dose or divided every 6-12 hours; dose varies by indication and severity.

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.
Terminal half-life: 2-4 hours (plasma); clinical effects persist longer (18-36 hours) due to prolonged receptor occupancy and transcriptional effects.
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.
Renal: primarily as metabolites, <20% unchanged; small fecal/biliary contribution.
