CORTRIL vs KENALOG
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.
Triamcinolone acetonide is a synthetic corticosteroid with potent glucocorticoid and weak mineralocorticoid activity. It binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, decreased release of arachidonic acid, and reduced synthesis of prostaglandins and leukotrienes. It also suppresses cytokine production and immune cell migration.
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.
Kenalog (triamcinolone acetonide) 40-80 mg intramuscularly (deep gluteal) every 4 weeks; or 0.5-1 mg/kg intravenously every 24 hours (for acute conditions).

Terminal elimination half-life: 1.5–2.5 hours. Clinically, the biologic half-life (duration of ACTH suppression) is longer (8–12 hours).
Terminal half-life ~2-5 hours (triamcinolone acetonide); clinical duration prolonged due to crystalline depot formulation
Renal (95% as free cortisol and metabolites, primarily tetrahydrocortisol and glucuronide conjugates). Biliary/fecal excretion is minimal (<5%).
Renal (primarily as metabolites), ~30% unchanged; biliary/fecal minor (≤10%)
