Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; suppresses inflammation and immune responses by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and modulating gene transcription.
Glucocorticoid receptor agonist; inhibits inflammatory mediators including cytokines, chemokines, and adhesion molecules; reduces nasal inflammation.
Oral: Initial dose 50-100 mg twice daily; maintenance 25-50 mg twice daily. Maximum 200 mg/day.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.

Terminal elimination half-life: 2.6-3.8 hours. Clinical context: Short half-life requires multiple daily dosing; no significant accumulation with regular dosing.
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: 20-30% as unchanged drug; biliary/fecal: 70-80% as metabolites and unchanged drug.
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.
