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.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines, immune responses, and adrenal function.
2 inhalations (100 mcg each) twice daily orally, maximum 400 mcg/day.
5-60 mg orally once daily or divided as 5-15 mg every 4-12 hours; adjust based on response and condition.

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.
4-5 hours (terminal); prolonged in renal impairment (up to 12+ hours in anuria) and hepatic dysfunction; clinical context: dosing interval adjustment in severe renal failure
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: approximately 60-80% as unchanged drug and conjugated metabolites; biliary/fecal: minor (5-10%)
