Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone is a glucocorticoid receptor agonist. It binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of pro-inflammatory cytokines, chemokines, and adhesion molecules. It also inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis.
Glucocorticoid receptor agonist; inhibits inflammatory mediators including cytokines, chemokines, and adhesion molecules; reduces nasal inflammation.
4 to 48 mg/day orally or intramuscularly in divided doses every 12 hours; for acute conditions, up to 120 mg/day intravenously in divided doses every 4-6 hours.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.

Terminal elimination half-life: 2–4 hours. Clinical context: shorter than other corticosteroids; requires multiple daily doses for sustained anti-inflammatory effect.
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 hepatic metabolism; <20% excreted unchanged in urine. Negligible biliary/fecal elimination.
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.
