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.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory mediators (cytokines, prostaglandins, leukotrienes).
2 sprays (50 mcg/spray) per nostril once daily; may increase to 2 sprays per nostril twice daily if needed. Intranasal route.
5-60 mg/day orally in divided doses; typical starting dose 5-10 mg every 6-12 hours.

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.
2.1–3.5 hours (terminal elimination half-life; shorter half-life in children; prolonged in hepatic impairment).
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.
Primarily renal: prednisolone is excreted as glucuronide and sulfate conjugates; less than 1% unchanged. Biliary/fecal excretion accounts for <5%.
