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.
Betamethasone valerate is a corticosteroid that induces phospholipase A2 inhibitory proteins (lipocortins), which control the release of arachidonic acid from membrane phospholipids, thereby inhibiting prostaglandin and leukotriene synthesis. It has anti-inflammatory, antipruritic, and vasoconstrictive effects.
110 mcg (2 sprays) intranasally once daily; after 1 week, may reduce to 55 mcg (1 spray) per nostril once daily for maintenance.
Topical: Apply a thin layer to affected skin once or twice daily. Maximum duration: 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.
Approximately 1.7 hours after topical application; systemic half-life is short due to rapid metabolism.
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, <5% unchanged); biliary/fecal elimination accounts for <10%.
