Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines (e.g., IL-1, IL-2, TNF-alpha). It 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 orally once daily or every other day, depending on condition. Initial dose may be up to 48 mg/day.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.

Terminal half-life of methylprednisolone is 2.5-3.5 hours; for the active metabolite (prednisolone), half-life is 2.1-3.5 hours. Clinical context: Despite short half-life, pharmacodynamic effects persist beyond plasma presence due to receptor-mediated actions.
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 (approximately 80-90% as metabolites, <5% unchanged); biliary/fecal (minor, <5%)
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.
