يستعمل دواء اوكيوفينيكول قطرة للعين 10ملocuphenicol 0.5% eye dps. 10 ml antibiotic antibiotic

description -an antibiotic first isolated from cultures of streptomyces venequelae in 1947 but now produced synthetically. it has a relatively simple structure and was the first broad-spectrum antibiotic to be discovered. it acts by interfering with bacterial protein synthesis and is mainly bacteriostatic. - -indication -used in treatment of cholera as it destroys the vibrios and decreases the diarrhea. it is effective against tetracycline-resistant vibrios. it is also used in eye drops or ointment to treat bacterial conjunctivitis. - -mechanism of action -chloramphenicol is lipid-soluble allowing it to diffuse through the bacterial cell membrane. it then reversibly binds to the l16 protein of the 50s subunit of bacterial ribosomes where transfer of amino acids to growing peptide chains is prevented (perhaps by suppression of peptidyl transferase activity) thus inhibiting peptide bond formation and subsequent protein synthesis.
