DELTA-CORTEF vs FLONASE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid; binds to glucocorticoid receptors, modulating gene expression to suppress 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.
Prednisolone (DELTA-CORTEF) typical adult dose: 5-60 mg orally once daily or in divided doses, depending on condition. For acute exacerbations: 20-60 mg orally daily. Route: oral. Frequency: once daily or divided.
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: 1.5-2.5 hours (mean ~2 hours) for prednisolone; clinical context: short-acting glucocorticoid, requires multiple daily dosing for sustained anti-inflammatory effect, adrenocortical suppression lasts approximately 1.25-1.5 days after discontinuation.
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: approximately 80-90% as unchanged drug and metabolites (primarily 20β-dihydrocortisone and other inactive conjugates); biliary/fecal: <10%.
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.
