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.
Betamethasone valerate is a corticosteroid that induces phospholipase A2 inhibitory proteins (lipocortins), which control the release of arachidonic acid from membrane phospholipids, thereby inhibiting prostaglandin and leukotriene synthesis. It has anti-inflammatory, antipruritic, and vasoconstrictive effects.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.
Topical: Apply a thin layer to affected skin once or twice daily. Maximum duration: 2 weeks.

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.
Approximately 1.7 hours after topical application; systemic half-life is short due to rapid metabolism.
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 (primarily as metabolites, <5% unchanged); biliary/fecal elimination accounts for <10%.
