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 with anti-inflammatory and immunosuppressive properties; suppresses multiple inflammatory cytokines and induces lipocortin synthesis.
110 mcg (2 sprays) intranasally once daily; after 1 week, may reduce to 55 mcg (1 spray) per nostril once daily for maintenance.
Intravenous: Initial dose 100-250 mg, then repeat every 10-30 minutes as needed. Intramuscular: 100-250 mg every 10-30 minutes. Intra-articular: 10-40 mg per joint every 1-2 weeks.

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 ~2-3 hours; clinically, adrenal suppression may persist >24h.
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.
Renally eliminated: ~80% as metabolites, <10% unchanged. Biliary/fecal: minor.
