Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Beta-2 adrenergic receptor agonist that stimulates adenylyl cyclase, increasing cAMP levels, leading to bronchodilation.
Glucocorticoid receptor agonist; inhibits inflammatory mediators including cytokines, chemokines, and adhesion molecules; reduces nasal inflammation.
Initial: 25 mg orally twice daily; may increase gradually to 100 mg twice daily based on tolerance and response.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.

Terminal elimination half-life is 3-5 hours in patients with normal renal function; prolonged to 10-20 hours in severe renal impairment (CrCl <30 mL/min).
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.
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%; the remainder undergoes hepatic 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.
