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.
Corticosteroid receptor agonist; modulates gene transcription to produce anti-inflammatory and immunosuppressive effects.
2 inhalations (100 mcg each) twice daily orally, maximum 400 mcg/day.
5 mg orally once daily for 7 days, then 5 mg orally every other day for 7 days. Alternatively, 1 mg/kg intravenously every 12 hours for 14 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.
3.5 ± 0.8 hours (terminal); prolonged in renal impairment (up to 12 hours in ESRD) and hepatic disease; requires dose adjustment in CrCl <30 mL/min
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 (80% as unchanged drug and metabolites, primarily via glomerular filtration and tubular secretion); biliary/fecal (15%)
