Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects via inhibition of phospholipase A2, reduction of prostaglandins and leukotrienes, and modulation of gene transcription.
Fluticasone propionate is a synthetic corticosteroid with anti-inflammatory activity. It binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory transcription factors (e.g., NF-κB) and increased synthesis of lipocortin-1, which reduces phospholipase A2 activity and subsequent release of arachidonic acid metabolites (prostaglandins, leukotrienes). In the lungs, it decreases airway inflammation by reducing eosinophil infiltration, mast cell degranulation, and cytokine release.
0.75-9 mg/day orally in divided doses every 6-12 hours; for anti-inflammatory/immunosuppressive effects, initial dose 0.75-9 mg/day; for cerebral edema, 10 mg IV then 4 mg IM/IV every 6 hours.
Inhalation aerosol: 88-880 mcg twice daily; typical starting dose: 88 mcg twice daily. Max: 880 mcg twice daily. Oral inhalation powder: 100-1000 mcg twice daily; typical starting: 100 mcg twice daily. Max: 1000 mcg twice daily.

Terminal elimination half-life: 36-54 hours (adults); clinically, biological half-life (duration of HPA axis suppression) is longer (24-72 hours).
Approximately 14.4 hours (range 7.8–24.6 hours) for the inhaled route; supports twice-daily dosing; prolonged in hepatic impairment.
Renal (approximately 65-80% as metabolites, <10% as unchanged drug); biliary/fecal (minor).
Primarily hepatic metabolism (CYP3A4) with fecal excretion of metabolites; renal excretion accounts for <5% of the dose as unchanged drug and metabolites combined.
