CHLOROMYCETIN HYDROCORTISONE vs KENALOG IN ORABASE
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.
Corticosteroid that binds to glucocorticoid receptors, modulating gene expression to reduce inflammation, suppress immune response, and inhibit fibroblast proliferation.
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.
Apply a thin layer to the affected area 2-4 times daily, after meals and at bedtime. Do not rub in; allow to form a film.

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 half-life approximately 2-5 hours following mucosal application.
Renal: ~80-90% of chloramphenicol as inactive metabolites (glucuronide conjugate) and 5-10% unchanged. Biliary: <3% of unchanged drug. Fecal: minimal.
Primarily hepatic metabolism; metabolites excreted renally (~75%) and in feces (~10%).
