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.
Dexamethasone is a glucocorticoid receptor agonist, binding to the glucocorticoid receptor (GR) and modulating gene expression through transactivation and transrepression. It inhibits phospholipase A2, reduces prostaglandin and leukotriene synthesis, suppresses cytokine production (IL-1, IL-2, IL-6, TNF-alpha), and decreases immune cell migration and activation.
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.
0.5 mg orally once daily, with gradual taper to lowest effective dose

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.
3.0-4.5 hours; prolonged in hepatic impairment (up to 6-8 hours) or concurrent CYP3A4 inhibitors
Renal: ~80-90% of chloramphenicol as inactive metabolites (glucuronide conjugate) and 5-10% unchanged. Biliary: <3% of unchanged drug. Fecal: minimal.
Renal: 70-80% (mostly as 6β-hydroxydexamethasone); biliary/fecal: 10-15%
