Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; induces phospholipase A2 inhibitory proteins (lipocortins), which suppress release of arachidonic acid and subsequent prostaglandin/leukotriene synthesis; also suppresses cytokine production and immune cell migration.
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.
Topical: Apply a thin layer to affected skin once or twice daily. Maximum use: 45 g/week.
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.

Terminal elimination half-life of approximately 2-3 hours; clinical context: duration of action may extend beyond half-life due to tissue binding.
Terminal elimination half-life is approximately 7.8 hours (range 6.5-10.6 hours) after inhalation, supporting twice-daily dosing.
Renal (approximately 80% as metabolites, <5% unchanged), biliary/fecal (remainder).
Primarily fecal (approximately 60-80%) after biliary elimination, with renal excretion accounting for <5% as unchanged drug and metabolites.
