Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluticasone propionate is a corticosteroid that binds to glucocorticoid receptors, inhibiting inflammatory mediators such as cytokines, leukotrienes, and prostaglandins, thereby reducing nasal inflammation.
Corticosteroid that binds to glucocorticoid receptors, leading to inhibition of phospholipase A2, decreased prostaglandin and leukotriene synthesis, and suppression of inflammatory cytokines.
2 sprays (50 mcg/spray) per nostril once daily; may increase to 2 sprays per nostril twice daily if needed. Intranasal route.
Intramuscular: 40-80 mg every 4 weeks. Intra-articular: 5-40 mg depending on joint size. Topical: Apply thin film to affected area 2-4 times daily.

Terminal elimination half-life is approximately 3 hours (range 2-4 hours). This short half-life supports twice-daily dosing for systemic effects; however, intranasal administration achieves local therapeutic concentrations with minimal systemic exposure.
Terminal elimination half-life approximately 2-5 hours; but suppression of adrenal function (HPA axis) can persist for 7-30 days depending on dose and duration.
Primarily hepatic metabolism (CYP3A4), with metabolites excreted in feces (approximately 87-90%) and urine (<5% unchanged). Less than 5% of a dose is excreted renally as unchanged drug.
Renal (primarily as metabolites, <5% unchanged); biliary/fecal (minor).
