Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; inhibits inflammatory mediators including cytokines, chemokines, and adhesion molecules; reduces nasal inflammation.
Glucocorticoid receptor agonist; modulates gene expression leading to anti-inflammatory and immunosuppressive effects.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.
Topical: Apply a thin film to affected area twice daily. Maximum 2-week continuous use. In severe cases, apply up to 4 times daily. Do not exceed 50 g/week.

The terminal elimination half-life of mometasone furoate is approximately 5.8 hours. This short half-life supports once-daily dosing for intranasal use, but systemic accumulation is minimal with topical administration.
Terminal elimination half-life is 1.5-2 hours (intravenous) and 2-3 hours (oral), reflecting rapid clearance; clinical context: supports twice-daily dosing for systemic effects.
Mometasone furoate is predominantly eliminated via biliary/fecal excretion. After intravenous administration, approximately 74% of the dose is recovered in feces and about 8% in urine. The drug undergoes extensive hepatic metabolism, and metabolites are excreted primarily in bile.
Renal: 60-70% as metabolites; biliary/fecal: 20-30% as metabolites; unchanged drug: <5%.
