Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone acetate is a synthetic glucocorticoid receptor agonist that modulates gene expression to suppress inflammation, immune responses, and adrenal function by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing 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.
IV: 10-40 mg every 1-2 weeks; IM: 40-120 mg every 1-4 weeks; Intra-articular/soft tissue: 4-80 mg per injection, repeat every 1-5 weeks as needed.
50 mg orally once daily.

Plasma terminal elimination half-life: 2.5-4.0 hours (methylprednisolone acetate formulation). Duration of adrenal suppression correlates with tissue esterase hydrolysis and prolonged tissue retention.
Terminal elimination half-life is 12 hours (range 10–14 hours) in healthy adults; prolonged to 24–30 hours in severe hepatic impairment.
Primarily hepatic metabolism; renal excretion of metabolites (<10% unchanged). Fecal excretion is minor (<5%).
Renal excretion of unchanged drug accounts for 70% of elimination; biliary/fecal elimination accounts for 20%; 10% metabolized to inactive metabolites.
