CHLOROMYCETIN HYDROCORTISONE vs FLORONE E
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.
FLORONE E contains diflorasone diacetate, a corticosteroid that induces phospholipase A2 inhibitory proteins (lipocortins), inhibiting arachidonic acid release and reducing prostaglandin and leukotriene synthesis, resulting in anti-inflammatory, antipruritic, and vasoconstrictive effects.
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 film to affected skin area twice daily. Not for ophthalmic, oral, or intravaginal use.

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.
Approximately 2-4 hours (terminal) for the active moiety diflorasone; clinically, this supports twice-daily dosing for chronic skin conditions.
Renal: ~80-90% of chloramphenicol as inactive metabolites (glucuronide conjugate) and 5-10% unchanged. Biliary: <3% of unchanged drug. Fecal: minimal.
Primarily renal (<1% unchanged as metabolite) and biliary, with <1% excreted unchanged in urine. The remainder is metabolized and excreted in feces via bile.
