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.
Agonist of glucocorticoid receptors, leading to anti-inflammatory and immunosuppressive effects via inhibition of phospholipase A2, reduction of pro-inflammatory cytokines, and suppression of immune cell activity.
1 inhalation (50 mcg) twice daily, administered via oral inhalation.
Initial dose: 5-60 mg orally or intravenously once daily or divided every 12-24 hours; range 5-60 mg/day. For acute conditions, 40-60 mg once daily.

Terminal elimination half-life is approximately 14-17.5 hours; this supports once- or twice-daily dosing in asthma maintenance.
Terminal elimination half-life is 2.1–3.5 hours in adults (mean 2.6 h). Clinical context: Short half-life supports twice-daily dosing for most conditions; prolonged in hepatic impairment (up to 8 h).
Primarily fecal (87-90%) after hepatic metabolism; renal excretion accounts for <5% as unchanged drug and metabolites.
Renal excretion of inactive metabolites (primarily prednisolone) accounts for >80% of elimination; less than 10% excreted unchanged. Biliary/fecal excretion is negligible (<5%).
