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, binding to glucocorticoid response elements to modulate gene transcription, resulting in anti-inflammatory, immunosuppressive, anti-allergic, and anti-shock effects.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
Oral: 0.75–9 mg/day divided every 6–12 hours; IV/IM: 0.5–9 mg/day divided every 6–12 hours.

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
Terminal elimination half-life: 2-3 hours (oral); clinical effects persist longer due to glucocorticoid receptor-mediated genomic actions
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Renal excretion of metabolites (<5% unchanged drug); minor biliary/fecal elimination (<1%)
