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.
Corticosteroid that binds to glucocorticoid receptors, altering gene expression to inhibit inflammatory mediators (e.g., prostaglandins, leukotrienes) and suppress immune cell activity.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.
Apply a thin film to the affected area once or twice daily for up to 2 weeks, using the lowest effective dose. Not for use under occlusive dressings or on large areas.

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 half-life: 2-3 hours (topical) due to rapid clearance; systemic half-life: 1-2 hours
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: 90% as metabolites; biliary/fecal: minimal (<5%)
