Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Agonist at glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response.
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.
0.6 mg/kg orally once daily (maximum 60 mg/day); titrate to lowest effective dose based on clinical response.
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.

6.2 hours (range 4.5–8.1 h) in healthy adults; prolonged in hepatic impairment.
Approximately 14.4 hours (range 7.8–24.6 hours) for the inhaled route; supports twice-daily dosing; prolonged in hepatic impairment.
Renal excretion of inactive metabolites; less than 5% excreted as unchanged drug in urine. Biliary/fecal elimination accounts for <1%.
Primarily hepatic metabolism (CYP3A4) with fecal excretion of metabolites; renal excretion accounts for <5% of the dose as unchanged drug and metabolites combined.
