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.
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.
Initial 4-48 mg/day oral in divided doses, tapered. For pulse therapy: 1 g IV daily for 3 days.
1 inhalation (50 mcg) twice daily, administered via oral inhalation.

2-3 hours (terminal); clinical effect persists longer due to intracellular receptor binding.
Terminal elimination half-life is approximately 14-17.5 hours; this supports once- or twice-daily dosing in asthma maintenance.
Renal (mainly as inactive metabolites); <5% unchanged. Biliary/fecal excretion is minimal.
Primarily fecal (87-90%) after hepatic metabolism; renal excretion accounts for <5% as unchanged drug and metabolites.
