Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to glucocorticoid receptors, inhibiting inflammatory mediators such as prostaglandins, leukotrienes, and cytokines, thereby reducing nasal inflammation.
Corticosteroid with anti-inflammatory activity; binds to glucocorticoid receptors, inhibiting inflammatory mediators like prostaglandins and leukotrienes.
2 sprays (50 mcg/spray) in each nostril once or twice daily; maximum 8 sprays/day.
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 half-life approximately 15-25 minutes for flunisolide (the active ingredient in NASAREL) in the systemic circulation after intranasal administration. Clinically, the half-life is short, reducing the risk of systemic accumulation but requiring twice-daily dosing for consistent effect.
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; renal excretion of metabolites accounts for <30% of dose. Fecal elimination minimal (<5%).
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%).
