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 with high glucocorticoid receptor affinity; reduces inflammation by inhibiting phospholipase A2, decreasing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
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.
0.5% ophthalmic suspension: 1-2 drops into affected eye(s) four times daily. In severe cases, may be increased to 1-2 drops every hour during the first week, then taper.

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 elimination half-life is 2.2-4.3 hours; clinical context: supports twice-daily dosing in ophthalmic use, with minimal systemic accumulation.
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.
Primarily hepatic metabolism; metabolites excreted in urine (approximately 80% as inactive metabolites) and feces (15-20%). Less than 1% excreted unchanged in urine.
