Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone acetate is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene expression to suppress inflammation, immune response, and adrenal function. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, and decreases cytokine production.
Triamcinolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression. It suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing cytokine production.
40-80 mg intramuscular (IM) or intra-articular (IA) injection; for IM use, dose may be repeated every 1-4 weeks as needed. Maximum single IM dose: 120 mg.
50 mg orally once daily.

Terminal half-life: 3-3.5 hours; correlates with duration of anti-inflammatory effect due to receptor-mediated action.
Terminal elimination half-life is 12 hours (range 10–14 hours) in healthy adults; prolonged to 24–30 hours in severe hepatic impairment.
Renal: <10% unchanged; extensive hepatic metabolism to inactive metabolites primarily excreted renally as glucuronides and sulfates.
Renal excretion of unchanged drug accounts for 70% of elimination; biliary/fecal elimination accounts for 20%; 10% metabolized to inactive metabolites.
