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; modulates gene expression to inhibit pro-inflammatory cytokines, phospholipase A2, and NF-κB; suppresses immune response and inflammation.
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).
5-60 mg orally once daily or divided every 12-24 hours; dose depends on condition and severity. For acute exacerbations, 200-400 mg intramuscularly once.

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: 2-4 hours (plasma); biological (tissue) half-life: 18-36 hours due to prolonged glucocorticoid receptor-mediated effects. Half-life prolonged in hepatic disease.
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 (fraction excreted unchanged: <1%); primarily hepatic metabolism to inactive glucuronide and sulfate conjugates eliminated renally and fecally. After oral administration, 12-15% of dose recovered in bile/feces as metabolites.
