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.
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.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
1.5 mg orally once daily

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
Terminal half-life approximately 3-4 hours (dexamethasone), with clinical effects persisting 36-54 hours due to glucocorticoid receptor-mediated actions.
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Renal (primarily as metabolites, ~60%), biliary/fecal (~30%), with <5% excreted unchanged.
