Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects via inhibition of phospholipase A2, reduction of prostaglandins and leukotrienes, and modulation of gene transcription.
Corticosteroid with anti-inflammatory, immunosuppressive, and antiproliferative properties; suppresses cytokine production, inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, and stabilizes lysosomal membranes.
0.75-9 mg/day orally in divided doses every 6-12 hours; for anti-inflammatory/immunosuppressive effects, initial dose 0.75-9 mg/day; for cerebral edema, 10 mg IV then 4 mg IM/IV every 6 hours.
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: 36-54 hours (adults); clinically, biological half-life (duration of HPA axis suppression) is longer (24-72 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 (approximately 65-80% as metabolites, <10% as unchanged drug); biliary/fecal (minor).
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.
