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.
Synthetic glucocorticoid that binds to the glucocorticoid receptor, leading to regulation of gene expression and suppression of inflammatory cytokines, immune response, and adrenal function.
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.
Adult: 0.75-9 mg/day orally in divided doses every 6-12 hours; IV/IM: initial 0.5-9 mg/day in divided doses every 6-12 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: 36-54 hours; prolonged in hepatic impairment (up to 72 hours) due to reduced clearance.
Renal: ~80-90% of chloramphenicol as inactive metabolites (glucuronide conjugate) and 5-10% unchanged. Biliary: <3% of unchanged drug. Fecal: minimal.
Primarily renal: ~65-80% as unchanged drug and metabolites via glomerular filtration, with tubular reabsorption; minor biliary/fecal (5-10%).
