Chloramphenicol Palmitate（Cat No.:R023220）is an esterified prodrug form of chloramphenicol, designed to enhance its stability and palatability, especially for pediatric use. Once administered, it converts to active chloramphenicol, a broad-spectrum antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, leading to bacterial growth inhibition. Chloramphenicol Palmitate is effective against a wide range of gram-positive and gram-negative bacteria and is commonly used for serious infections like typhoid fever and meningitis. Its improved taste and stability make it suitable for oral suspensions in children.
