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.
Hydrocortisone is a corticosteroid that binds to the glucocorticoid receptor, leading to anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
2 sprays (50 mcg/spray) per nostril once daily; may increase to 2 sprays per nostril twice daily if needed. Intranasal route.
100-500 mg intravenously every 2-6 hours for initial management of adrenal insufficiency; oral maintenance: 20-30 mg daily in divided doses (e.g., 10 mg morning, 5 mg afternoon).

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.
Terminal elimination half-life: 1.5–2.5 hours (plasma), but biological half-life (duration of HPA axis suppression) is 8–12 hours.
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.
Renal (primarily as inactive metabolites; <5% unchanged) and biliary/fecal (minor).
