Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a glucocorticoid receptor agonist, binding to the glucocorticoid receptor (GR) and modulating gene expression through transactivation and transrepression. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, suppresses cytokine production (IL-1, IL-2, IL-6, TNF-alpha), and decreases immune cell migration and activation.
Methylprednisolone is a glucocorticoid receptor agonist. It binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of pro-inflammatory cytokines, chemokines, and adhesion molecules. It also inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis.
0.5 mg orally once daily, with gradual taper to lowest effective dose
4 to 48 mg/day orally or intramuscularly in divided doses every 12 hours; for acute conditions, up to 120 mg/day intravenously in divided doses every 4-6 hours.

3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Terminal elimination half-life: 2–4 hours. Clinical context: shorter than other corticosteroids; requires multiple daily doses for sustained anti-inflammatory effect.
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
Primarily hepatic metabolism; <20% excreted unchanged in urine. Negligible biliary/fecal elimination.
