Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with predominant glucocorticoid activity; binds to glucocorticoid receptors, modulating gene expression and suppressing inflammatory mediators (e.g., prostaglandins, leukotrienes) and immune cell function.
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.
DRICORT (dexamethasone) typical adult dose: 0.5-9 mg/day orally in divided doses every 6-12 hours, or 0.5-24 mg IV/IM once or divided. Anti-inflammatory: 0.75-9 mg/day PO/IV in 2-4 divided doses. Severe conditions: up to 16 mg/day in divided doses. Short-term high-dose: up to 40-100 mg IV push for specific indications.
110 mcg (2 sprays) intranasally once daily; after 1 week, may reduce to 55 mcg (1 spray) per nostril once daily for maintenance.

Terminal elimination half-life is 10-12 hours in adults with normal renal function, allowing twice-daily dosing.
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.
Primarily renal (80-85% as unchanged drug and metabolites), with 15-20% excreted in feces via biliary elimination.
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.
