CHLOROMYCETIN HYDROCORTISONE vs EXSERVAN
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.
Exservan (riluzole) is a benzothiazole derivative that modulates glutamatergic neurotransmission. Its mechanism of action involves inhibition of glutamate release, inactivation of voltage-dependent sodium channels, and interference with neurotransmitter binding to excitatory amino acid receptors.
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.
Adults: 15 mg orally once daily in the morning; increase to 30 mg after 2 weeks if needed. Maximum 30 mg/day.

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 is approximately 3–4 hours in patients with normal renal function; prolonged in renal impairment (up to 8–10 hours in ESRD).
Renal: ~80-90% of chloramphenicol as inactive metabolites (glucuronide conjugate) and 5-10% unchanged. Biliary: <3% of unchanged drug. Fecal: minimal.
Primarily renal excretion as unchanged drug: 80% excreted unchanged in urine; approximately 20% as metabolites; biliary/fecal <5%.
