Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Glucocorticoid receptor agonist that modulates gene expression, leading to anti-inflammatory, immunosuppressive, and vasoconstrictive effects.
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.
Topical: Apply a thin layer to affected area 2-4 times daily.

Terminal elimination half-life is approximately 7.8 hours (range 6.5-10.6 hours) after inhalation, supporting twice-daily dosing.
Terminal elimination half-life: 1-2 hours (plasma cortisol); biological half-life (duration of action) 8-12 hours due to intracellular receptor effects.
Primarily fecal (approximately 60-80%) after biliary elimination, with renal excretion accounting for <5% as unchanged drug and metabolites.
Renal: primarily as 17-hydroxycorticosteroids and 17-ketosteroids; <5% unchanged. Biliary/fecal: minimal. Metabolites conjugated with glucuronide or sulfate.
