Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that reduces inflammation by inhibiting phospholipase A2, decreasing arachidonic acid release, and suppressing prostaglandin and leukotriene synthesis.
Corticosteroid with anti-inflammatory activity; binds to glucocorticoid receptors, inhibiting inflammatory mediators like prostaglandins and leukotrienes.
2 sprays (100 mcg total) per nostril twice daily; maximum 8 sprays (400 mcg) per day in each nostril.
Mometasone furoate 200 mcg per day as 2 sprays (50 mcg/spray) in each nostril once daily. May reduce to 100 mcg per day (1 spray per nostril once daily) if symptoms controlled. Maximum 200 mcg per day.

Terminal elimination half-life: 1-2 hours; clinically, intranasal dosing achieves prolonged local effects with minimal systemic accumulation.
The terminal elimination half-life of mometasone furoate following intranasal administration is approximately 5.8 hours (range 2.7–11.5 hours) in adults, reflecting rapid clearance from systemic circulation.
Primarily hepatic metabolism via CYP3A4; metabolites and unchanged drug excreted in feces (approximately 60%) and urine (approximately 40%, with <1% unchanged).
Mometasone furoate is extensively metabolized in the liver, primarily via CYP3A4, and metabolites are excreted mostly in feces (approximately 74%) and to a lesser extent in urine (approximately 8%).
