Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines, suppression of inflammatory cell migration, and reduction of mucosal edema.
Adrenocorticosteroid; binds to glucocorticoid receptor, modulating gene expression to produce anti-inflammatory, immunosuppressive, and metabolic effects.
110 mcg (2 sprays) intranasally once daily; after 1 week, may reduce to 55 mcg (1 spray) per nostril once daily for maintenance.
10-20 mg orally once daily

The terminal elimination half-life of fluticasone propionate after intravenous administration is approximately 7.8 hours. After intranasal administration, due to slow absorption from the nasal mucosa and extensive first-pass metabolism, the apparent half-life is prolonged, ranging from 10 to 15 hours, reflecting the flip-flop pharmacokinetics.
2-3 h. The terminal elimination half-life is short, requiring thrice-daily dosing for sustained effect. Context: In patients with hepatic impairment, half-life may be prolonged up to 4-5 h.
Fluticasone propionate is eliminated primarily via hepatic metabolism and subsequent renal excretion. Following oral administration, approximately 87-90% of the dose is excreted in feces as metabolites, with less than 5% excreted unchanged in urine. After intranasal administration, the swallowed portion undergoes first-pass metabolism, and systemic absorption is minimal; the eliminated fraction follows the same pattern.
Primarily hepatic metabolism (>90%) with renal excretion of inactive metabolites (approximately 80% in urine, 20% in feces). Less than 5% of the parent drug is excreted unchanged in urine.
