How Chloramphenicol Indo Farma works

Chloramphenicol Indo Farma 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.

Toxicity

Oral, mouse: LD₅₀ = 1500 mg/kg; Oral, rat: LD₅₀ = 2500 mg/kg. Toxic reactions including fatalities have occurred in the premature and newborn; the signs and symptoms associated with these reactions have been referred to as the gray syndrome. Symptoms include (in order of appearance) abdominal distension with or without emesis, progressive pallid cyanosis, vasomotor collapse frequently accompanied by irregular respiration, and death within a few hours of onset of these symptoms.

Precaution

Impaired renal or hepatic function; premature and full-term neonates. Monitor plasma concentrations to avoid toxicity.
