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 corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of pro-inflammatory cytokines, suppression of inflammatory cell migration, and reduction of mucosal edema.
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.
110 mcg (2 sprays) intranasally once daily; after 1 week, may reduce to 55 mcg (1 spray) per nostril once daily for maintenance.

Terminal elimination half-life is approximately 2.5-3 hours in adults. The half-life may be prolonged in patients with hepatic impairment.
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.
Primarily hepatic metabolism; <10% excreted unchanged in urine. Fecal excretion accounts for approximately 30% of metabolites. Renal excretion of metabolites accounts for about 60%.
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.
