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.
Corticosteroid with anti-inflammatory and immunosuppressive properties; suppresses inflammatory cytokines and immune cell activity.
1 inhalation (50 mcg) twice daily, administered via oral inhalation.
IV or IM: 10-40 mg methylprednisolone (as sodium succinate) every 4-6 hours; high-dose pulse therapy: 30 mg/kg IV over 30-60 minutes every 4-6 hours for 48-72 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: 2.5–3.5 hours. In clinical context, the biologic half-life (suppression of HPA axis) is longer (24–36 hours) due to tissue retention of active metabolites.
Primarily fecal (87-90%) after hepatic metabolism; renal excretion accounts for <5% as unchanged drug and metabolites.
Renal: approximately 80% as metabolites (glucuronide and sulfate conjugates) and unchanged drug; biliary/fecal: less than 5%.
