CHLOROMYCETIN HYDROCORTISONE vs CORTRIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chloromycetin (chloramphenicol) is a bacteriostatic antibiotic that inhibits protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation. Hydrocortisone is a corticosteroid that suppresses inflammation by inhibiting phospholipase A2 and reducing prostaglandin and leukotriene synthesis.
Cortril (hydrocortisone) is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators and suppression of immune response.
Apply 1-2 drops or a small amount (approximately 0.5 cm ribbon) into the affected eye(s) every 3-4 hours, or more frequently as needed. For severe infections, may be used every 2 hours. Not to exceed 6 times daily. Otic: Instill 3-4 drops into the affected ear(s) 2-3 times daily.
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.

Chloramphenicol: 1.5-4 hours in adults with normal hepatic function; prolonged to 3-7 hours in neonates and up to 15 hours in severe liver disease. Hydrocortisone: 1-2 hours.
Terminal elimination half-life: 1.5–2.5 hours. Clinically, the biologic half-life (duration of ACTH suppression) is longer (8–12 hours).
Renal: ~80-90% of chloramphenicol as inactive metabolites (glucuronide conjugate) and 5-10% unchanged. Biliary: <3% of unchanged drug. Fecal: minimal.
Renal (95% as free cortisol and metabolites, primarily tetrahydrocortisol and glucuronide conjugates). Biliary/fecal excretion is minimal (<5%).
