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.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, and adrenal function.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 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.
Terminal elimination half-life: 3-4 hours in adults; prolonged in hepatic impairment (up to 8 hours).
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: 60-70% as metabolites, 5-10% unchanged; Biliary/fecal: 20-30% as metabolites.
