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 that binds to glucocorticoid receptors, increasing the synthesis of lipocortins, which inhibit phospholipase A2, thereby reducing arachidonic acid release and decreasing prostaglandin and leukotriene production. It also suppresses inflammatory cell migration and cytokine release, leading to reduced airway inflammation and hyperreactivity.
0.6 mg/kg orally once daily (maximum 60 mg/day); titrate to lowest effective dose based on clinical response.
Adult: 88-880 mcg twice daily via oral inhalation; typical starting dose: 88 mcg twice daily for patients previously on bronchodilators alone, 220 mcg twice daily for patients on inhaled corticosteroids.

6.2 hours (range 4.5–8.1 h) in healthy adults; prolonged in hepatic impairment.
Terminal elimination half-life is approximately 7.8 hours (range 6.5-10.6 hours) after inhalation, supporting twice-daily dosing.
Renal excretion of inactive metabolites; less than 5% excreted as unchanged drug in urine. Biliary/fecal elimination accounts for <1%.
Primarily fecal (approximately 60-80%) after biliary elimination, with renal excretion accounting for <5% as unchanged drug and metabolites.
