Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid agonist; binds to glucocorticoid receptors, inhibiting inflammatory mediators (e.g., cytokines, prostaglandins) and reducing nasal mucosal inflammation.
Glucocorticoid receptor agonist; suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene transcription.
2 sprays (50 mcg each) per nostril once daily, total daily dose 200 mcg. If inadequate, may increase to 2 sprays per nostril twice daily (400 mcg/day).
Oral: Initial dose 50-100 mg twice daily; maintenance 25-50 mg twice daily. Maximum 200 mg/day.

Terminal elimination half-life is approximately 10 hours (range 7–14 hours), reflecting slow release from tissue binding sites; accumulation occurs with once-daily dosing, achieving steady state in 1–2 weeks.
Terminal elimination half-life: 2.6-3.8 hours. Clinical context: Short half-life requires multiple daily dosing; no significant accumulation with regular dosing.
Primarily hepatic metabolism via CYP3A4; renal excretion accounts for <5% as unchanged drug, with the remainder as metabolites in feces (approximately 90%) and urine (approximately 5%).
Renal: 20-30% as unchanged drug; biliary/fecal: 70-80% as metabolites and unchanged drug.
