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.
Prednisolone is a synthetic glucocorticoid that binds to the glucocorticoid receptor, modulating gene transcription to suppress inflammation, immune response, and adrenal function.
110 mcg (2 sprays) intranasally once daily; after 1 week, may reduce to 55 mcg (1 spray) per nostril once daily for maintenance.
20-40 mg intramuscularly every 3 weeks; for intra-articular use: 20-40 mg per large joint, 10-20 mg per medium joint, 4-10 mg per small joint.

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.
Plasma t1/2 ~2.5-3.5 hours. Duration of adrenal suppression may persist for 24-48 hours.
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.
Primarily renal (80-90% as inactive metabolites and unchanged drug). Biliary excretion accounts for <5%.
