Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to regulation of gene expression and suppression of inflammatory cytokines, immune response, and adrenal function.
Glucocorticoid receptor agonist; inhibits inflammatory mediators including cytokines, chemokines, and adhesion molecules; reduces nasal inflammation.
Adult: 0.75-9 mg/day orally in divided doses every 6-12 hours; IV/IM: initial 0.5-9 mg/day in divided doses every 6-12 hours.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.

Terminal elimination half-life: 36-54 hours; prolonged in hepatic impairment (up to 72 hours) due to reduced clearance.
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.
Primarily renal: ~65-80% as unchanged drug and metabolites via glomerular filtration, with tubular reabsorption; minor biliary/fecal (5-10%).
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.
