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 corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines, immune responses, 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.
5-60 mg orally once daily or divided as 5-15 mg every 4-12 hours; adjust based on response and condition.

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.
4-5 hours (terminal); prolonged in renal impairment (up to 12+ hours in anuria) and hepatic dysfunction; clinical context: dosing interval adjustment in severe renal failure
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 60-80% as unchanged drug and conjugated metabolites; biliary/fecal: minor (5-10%)
