Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Triamcinolone acetonide is a synthetic corticosteroid with potent anti-inflammatory, immunosuppressive, and anti-proliferative effects. It binds to the glucocorticoid receptor, leading to modulation of gene expression and inhibition of phospholipase A2, which reduces prostaglandin and leukotriene synthesis. It also suppresses cytokine production and immune cell migration.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (cytokines, prostaglandins, leukotrienes).
60 mg (1.5 mL) intramuscularly (deep IM) as a single dose for allergic/ inflammatory conditions; intra-articular or soft tissue injection: 10-40 mg for large joints, 5-25 mg for medium joints, 2.5-10 mg for small joints; intralesional: up to 1 mg per injection site, repeated as needed.
5-60 mg/day orally in divided doses; typical starting dose 5-10 mg every 6-12 hours.

Terminal elimination half-life: 2–4 hours for triamcinolone acetonide; prolonged in hepatic impairment (up to 6–8 hours).
2.1–3.5 hours (terminal elimination half-life; shorter half-life in children; prolonged in hepatic impairment).
Primarily hepatic metabolism followed by renal excretion of inactive metabolites; less than 5% excreted unchanged in urine, with minor biliary/fecal elimination (<2%).
Primarily renal: prednisolone is excreted as glucuronide and sulfate conjugates; less than 1% unchanged. Biliary/fecal excretion accounts for <5%.
