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.
Triamcinolone acetonide is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, reduced prostaglandin and leukotriene synthesis, and suppression of inflammatory mediators.
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.
2-40 mg (0.1-1 mL) intra-articular, intralesional, or soft tissue injection; intra-articular dose depends on joint size (large joint: 10-40 mg, medium joint: 5-25 mg, small joint: 2-10 mg); repeat every 2-3 weeks as needed.

Terminal elimination half-life: 36-54 hours (adults); clinically, biological half-life (duration of HPA axis suppression) is longer (24-72 hours).
The terminal elimination half-life is approximately 2-3 hours for triamcinolone acetonide. In the context of intra-articular or intralesional administration, the half-life at the site of action is prolonged due to slow release from the injection depot, providing sustained local effects.
Renal (approximately 65-80% as metabolites, <10% as unchanged drug); biliary/fecal (minor).
Renal excretion of metabolites (primarily conjugated and unconjugated) accounts for approximately 80-90% of an administered dose, with less than 5% excreted unchanged in urine. Biliary/fecal elimination accounts for the remainder, about 10-20%.
