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.
Corticosteroid that binds to glucocorticoid receptors, leading to modulation of gene expression and suppression of inflammatory mediators (e.g., prostaglandins, leukotrienes) and immune cell activity.
110 mcg (2 sprays) intranasally once daily; after 1 week, may reduce to 55 mcg (1 spray) per nostril once daily for maintenance.
20-60 mg intramuscularly or intra-articularly once daily as a single dose or divided every 6-12 hours; dose varies by indication and severity.

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.
Terminal half-life: 2-4 hours (plasma); clinical effects persist longer (18-36 hours) due to prolonged receptor occupancy and transcriptional effects.
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.
Renal: primarily as metabolites, <20% unchanged; small fecal/biliary contribution.
