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; inhibits phospholipase A2, decreases prostaglandin and leukotriene synthesis; suppresses cytokine production and immune cell activity.
2 inhalations (100 mcg each) twice daily orally, maximum 400 mcg/day.
4-48 mg/day orally in divided doses; 10-40 mg IV/IM bolus, then 10-40 mg IV q4-6h; high-dose IV pulse: 1 g/day for 3 days.

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.
Plasma: 2.5-3.5 hours; biological half-life (tissue): 18-36 hours due to glucocorticoid receptor-mediated effects; clinical context: anti-inflammatory effects persist beyond plasma clearance
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 (primarily as inactive metabolites, <10% unchanged); minor biliary/fecal elimination
