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 that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2, decreased prostaglandin and leukotriene synthesis, and suppression of inflammatory cytokines.
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).
Intramuscular: 40-80 mg every 4 weeks. Intra-articular: 5-40 mg depending on joint size. Topical: Apply thin film to affected area 2-4 times daily.

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 approximately 2-5 hours; but suppression of adrenal function (HPA axis) can persist for 7-30 days depending on dose and duration.
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 (primarily as metabolites, <5% unchanged); biliary/fecal (minor).
