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.
Mineralocorticoid receptor agonist; promotes sodium reabsorption and potassium excretion in renal distal tubules, increasing extracellular fluid volume. Also has glucocorticoid activity.
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.
0.1 mg orally once daily, range 0.05-0.2 mg/day

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 3.5 hours (range 2–5 h); clinical effect duration exceeds half-life due to mineralocorticoid receptor binding.
Renal (95% as free cortisol and metabolites, primarily tetrahydrocortisol and glucuronide conjugates). Biliary/fecal excretion is minimal (<5%).
Renal (80%) as inactive metabolites; less than 5% unchanged; minor biliary/fecal elimination.
