CORTRIL vs DEPO-MEDROL
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.
Methylprednisolone acetate is a synthetic glucocorticoid receptor agonist that modulates gene expression to suppress inflammation, immune responses, and adrenal function by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and decreasing 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.
IV: 10-40 mg every 1-2 weeks; IM: 40-120 mg every 1-4 weeks; Intra-articular/soft tissue: 4-80 mg per injection, repeat every 1-5 weeks as needed.

Terminal elimination half-life: 1.5–2.5 hours. Clinically, the biologic half-life (duration of ACTH suppression) is longer (8–12 hours).
Plasma terminal elimination half-life: 2.5-4.0 hours (methylprednisolone acetate formulation). Duration of adrenal suppression correlates with tissue esterase hydrolysis and prolonged tissue retention.
Renal (95% as free cortisol and metabolites, primarily tetrahydrocortisol and glucuronide conjugates). Biliary/fecal excretion is minimal (<5%).
Primarily hepatic metabolism; renal excretion of metabolites (<10% unchanged). Fecal excretion is minor (<5%).
