CORTRIL vs PREDNISONE INTENSOL
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.
Prednisone is a prodrug that is converted to prednisolone, which binds to the glucocorticoid receptor, modulating gene expression to produce anti-inflammatory and immunosuppressive effects by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppressing cytokine production.
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.
5-60 mg orally once daily or divided twice daily, titrated to response.

Terminal elimination half-life: 1.5–2.5 hours. Clinically, the biologic half-life (duration of ACTH suppression) is longer (8–12 hours).
2-4 hours (terminal) for prednisone; prednisolone half-life 2-4 hours. Clinical context: shorter than anti-inflammatory effect due to delayed receptor-mediated action.
Renal (95% as free cortisol and metabolites, primarily tetrahydrocortisol and glucuronide conjugates). Biliary/fecal excretion is minimal (<5%).
Renal: <30% unchanged; major metabolites (prednisolone, 20-dihydroprednisolone) conjugated and excreted in urine. Fecal: <10%.
