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.
Glucocorticoid receptor agonist; induces phospholipase A2 inhibitory proteins (lipocortins), which suppress release of arachidonic acid and subsequent prostaglandin/leukotriene synthesis; also suppresses cytokine production and immune cell migration.
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 use: 45 g/week.

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 elimination half-life of approximately 2-3 hours; clinical context: duration of action may extend beyond half-life due to tissue binding.
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 (approximately 80% as metabolites, <5% unchanged), biliary/fecal (remainder).
