Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Corticosteroid with anti-inflammatory and immunosuppressive properties; suppresses multiple inflammatory cytokines and induces lipocortin synthesis.
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.
Intravenous: Initial dose 100-250 mg, then repeat every 10-30 minutes as needed. Intramuscular: 100-250 mg every 10-30 minutes. Intra-articular: 10-40 mg per joint every 1-2 weeks.

Approximately 14.4 hours (range 7.8–24.6 hours) for the inhaled route; supports twice-daily dosing; prolonged in hepatic impairment.
Terminal half-life ~2-3 hours; clinically, adrenal suppression may persist >24h.
Primarily hepatic metabolism (CYP3A4) with fecal excretion of metabolites; renal excretion accounts for <5% of the dose as unchanged drug and metabolites combined.
Renally eliminated: ~80% as metabolites, <10% unchanged. Biliary/fecal: minor.
