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.
Corticosteroid with anti-inflammatory and immunosuppressive properties; suppresses inflammatory cytokines and immune cell activity.
2 sprays (50 mcg/spray) per nostril once daily; total dose 200 mcg/day.
IV or IM: 10-40 mg methylprednisolone (as sodium succinate) every 4-6 hours; high-dose pulse therapy: 30 mg/kg IV over 30-60 minutes every 4-6 hours for 48-72 hours.

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: 2.5–3.5 hours. In clinical context, the biologic half-life (suppression of HPA axis) is longer (24–36 hours) due to tissue retention of active metabolites.
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: approximately 80% as metabolites (glucuronide and sulfate conjugates) and unchanged drug; biliary/fecal: less than 5%.
