Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic glucocorticoid receptor agonist; modulates transcription via glucocorticoid response elements, suppressing inflammatory cytokines (e.g., IL-1, IL-6, TNF-α) and immune cell activity.
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.
Initial dose: 600 mg (6 tablets of 100 mg or 3 tablets of 200 mg) orally once daily for 4 weeks, then 400 mg orally once daily for weeks 5-8; total treatment duration 8 weeks.
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 is approximately 2.5-3 hours in adults. The half-life may be prolonged in patients with hepatic impairment.
Terminal elimination half-life is approximately 7.8 hours (range 6.5-10.6 hours) after inhalation, supporting twice-daily dosing.
Primarily hepatic metabolism; <10% excreted unchanged in urine. Fecal excretion accounts for approximately 30% of metabolites. Renal excretion of metabolites accounts for about 60%.
Primarily fecal (approximately 60-80%) after biliary elimination, with renal excretion accounting for <5% as unchanged drug and metabolites.
