Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mometasone furoate is a corticosteroid that exerts anti-inflammatory effects by inhibiting multiple inflammatory cell types and mediators, including eosinophils, mast cells, macrophages, and lymphocytes, and reducing the release of pro-inflammatory cytokines and chemokines.
Glucocorticoid receptor agonist; modulates gene expression leading to anti-inflammatory and immunosuppressive effects.
2 inhalations (100 mcg each) twice daily orally, maximum 400 mcg/day.
Topical: Apply a thin film to affected area twice daily. Maximum 2-week continuous use. In severe cases, apply up to 4 times daily. Do not exceed 50 g/week.

The terminal elimination half-life of mometasone furoate following inhalation is approximately 25 hours (range 15–40 hours), reflecting slow absorption from the lungs and prolonged systemic clearance.
Terminal elimination half-life is 1.5-2 hours (intravenous) and 2-3 hours (oral), reflecting rapid clearance; clinical context: supports twice-daily dosing for systemic effects.
Following oral inhalation, the absorbed fraction of mometasone furoate is extensively metabolized in the liver. Excretion is primarily via feces (approximately 74%) and urine (approximately 8%) as metabolites. Biliary excretion contributes to fecal elimination.
Renal: 60-70% as metabolites; biliary/fecal: 20-30% as metabolites; unchanged drug: <5%.
