Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators such as cytokines, prostaglandins, and leukotrienes. It also induces lipocortin synthesis, inhibits phospholipase A2, and reduces immune cell activity.
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.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
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.

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
Terminal elimination half-life: 2–4 hours for triamcinolone acetonide; prolonged in hepatic impairment (up to 6–8 hours).
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Primarily hepatic metabolism followed by renal excretion of inactive metabolites; less than 5% excreted unchanged in urine, with minor biliary/fecal elimination (<2%).
