CORTRIL vs FLONASE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cortril (hydrocortisone) is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators and suppression of immune response.
Fluticasone propionate is a corticosteroid that binds to glucocorticoid receptors, inhibiting inflammatory mediators such as cytokines, leukotrienes, and prostaglandins, thereby reducing nasal inflammation.
Hydrocortisone (Cortril) for adrenal insufficiency: 20-30 mg orally daily divided into two or three doses. For acute conditions, IV or IM hydrocortisone sodium succinate 100 mg every 8 hours.
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. Clinically, the biologic half-life (duration of ACTH suppression) is longer (8–12 hours).
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 (95% as free cortisol and metabolites, primarily tetrahydrocortisol and glucuronide conjugates). Biliary/fecal excretion is minimal (<5%).
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.
