Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexamethasone is a potent glucocorticoid that binds to glucocorticoid receptors, modulating gene expression to inhibit pro-inflammatory cytokines (e.g., IL-1, IL-6, TNF-α) and reduce inflammation, immune response, and adrenal function.
Fluticasone propionate is a corticosteroid that binds to glucocorticoid receptors, inhibiting inflammatory mediators such as cytokines, leukotrienes, and prostaglandins, thereby reducing nasal inflammation.
0.75 mg orally once daily, typically as part of a tapering regimen for anti-inflammatory or immunosuppressive effects.
2 sprays (50 mcg/spray) per nostril once daily; may increase to 2 sprays per nostril twice daily if needed. Intranasal route.

Terminal elimination half-life: 36-54 hours in adults with normal renal function; prolonged to 72-168 hours in severe renal impairment.
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.
Renal: ~65-80% as unchanged drug; Fecal: ~10-15% as metabolites; Minor biliary excretion.
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.
