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.
Corticosteroid receptor agonist; modulates gene transcription to produce anti-inflammatory and immunosuppressive effects.
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).
5 mg orally once daily for 7 days, then 5 mg orally every other day for 7 days. Alternatively, 1 mg/kg intravenously every 12 hours for 14 days.

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.
3.5 ± 0.8 hours (terminal); prolonged in renal impairment (up to 12 hours in ESRD) and hepatic disease; requires dose adjustment in CrCl <30 mL/min
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 (80% as unchanged drug and metabolites, primarily via glomerular filtration and tubular secretion); biliary/fecal (15%)
