Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; anti-inflammatory transcription factor modulation; inhibits phospholipase A2, reduces arachidonic acid release, decreases prostaglandin and leukotriene synthesis; suppresses cytokine production and inflammatory cell migration.
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.
1 inhalation (50 mcg) twice daily, administered via oral inhalation.
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.

Terminal elimination half-life is approximately 14-17.5 hours; this supports once- or twice-daily dosing in asthma maintenance.
Terminal elimination half-life: 2–4 hours. Clinical context: shorter than other corticosteroids; requires multiple daily doses for sustained anti-inflammatory effect.
Primarily fecal (87-90%) after hepatic metabolism; renal excretion accounts for <5% as unchanged drug and metabolites.
Primarily hepatic metabolism; <20% excreted unchanged in urine. Negligible biliary/fecal elimination.
