Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a long-acting glucocorticoid receptor agonist that suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene expression.
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.
1.5 mg orally once daily
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.

Terminal half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
Terminal half-life: 3-3.5 hours; correlates with duration of anti-inflammatory effect due to receptor-mediated action.
Renal (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
Renal: <10% unchanged; extensive hepatic metabolism to inactive metabolites primarily excreted renally as glucuronides and sulfates.
