Actions and Spectrum:Â
chloramphenicol is a broad-spectrum antibiotic that inhibits bacterial protein synthesis. Its mechanism of action involves interference with the bacterial ribosome, specifically the 50S subunit. Â
Spectrum of Activity:Â
chloramphenicol exhibits a broad spectrum of activity against both Gram-positive and Gram-negative bacteria. It is effective against a wide range of bacterial species, including those causing respiratory, urinary tract, skin, and gastrointestinal infections.Â
Frequency not definedÂ
NauseaÂ
Inflammation of the optic nerveÂ
RashÂ
HeadacheÂ
NightmaresÂ
Weakness in hands and feetÂ
Inflamed and sore mouthÂ
Black box warning:Â
NoneÂ
Contraindications/caution:Â
Pregnancy consideration: chloramphenicol crosses the placenta, so its use during pregnancy is discouragedÂ
Lactation: chloramphenicol is excreted in breast milk due to concerns about potential adverse effects on fetal and neonatal development. Â
Pregnancy category:Â
Category A: well-controlled and Satisfactory studies show no risk to the fetus in the first or later trimester.Â
Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women.Â
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.   Â
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.   Â
Category X: Drugs listed in this category outweigh the risks over benefits. Hence, these categories of drugs need to be avoided by pregnant women.   Â
Category N: There is no data available for the drug under this categoryÂ
Pharmacology:Â
Spectrum of Activity:Â
Pharmacokinetics:Â
AbsorptionÂ
chloramphenicol can be administered through various routes, including oral, intravenous (IV), and topical.Â
chloramphenicol is well-absorbed from the gastrointestinal tract when taken orally, but oral absorption can be variable. When applied topically, chloramphenicol can be absorbed through the skin, and the extent of absorption depends on the formulation.Â
DistributionÂ
chloramphenicol is distributed widely in various tissues, including the liver, kidneys, lungs, and central nervous system (CNS). It can penetrate tissues well, including the blood-brain barrier, making it effective in treating some central nervous system infections. A significant portion of chloramphenicol is bound to plasma proteins, primarily albumin.Â
MetabolismÂ
chloramphenicol is primarily metabolized in the liver through glucuronidation, forming inactive metabolites. The primary metabolic pathway involves the conjugation of chloramphenicol with glucuronic acid, leading to the formation of chloramphenicol glucuronide.Â
Elimination and ExcretionÂ
The elimination half-life of chloramphenicol is relatively long, and it can vary among individuals. Both the active drug and its metabolites are excreted in the urine. A significant portion of chloramphenicol is eliminated unchanged in the urine.Â
Administration:Â
