Basic Info

What is Chloramphenicol?

Chloramphenicol is a type of broad-spectrum antibiotic that can hinder the growth of bacteria generated by Streptomyces chloramphenicol. Natural chloramphenicol is L-body (additionally called levomycin). The artificial item is white or yellowish needle-like or half-cracked crystal, odorless, extremely bitter taste, slightly soluble in water, ether and also chloroform, quickly soluble in methanol, alcohol, acetone or ethyl acetate, insoluble in benzene and also petroleum ether. It is fairly secure in neutral or weakly acidic liquid option, and also it is very easy to fall short when it runs into alkali. The artificial item is a racemate, additionally referred to as Synmycin. Synthromycin is a blend of L- as well as D-forms of chloramphenicol. Due to the fact that the dextrorotary type has no anti-bacterial impact, the medicinal effect of synmycin is only half of that of all-natural products.

Chloramphenicol has inhibitory effects on Gram-negative microorganisms as well as Gram-positive microorganisms, as well as can be made use of to treat typhoid bacillary dysentery, urinary system infection, pertussis, pneumonia, blood poisoning as well as other diseases. Nevertheless, it is damaging to the liver, and also the dose and dose must purely comply with the medical professional’s recommendations. Chloramphenicol palmitate is insoluble in water, unappetizing when taken orally, additionally known as tasteless chloramphenicol. After consumption, chloramphenicol is launched by fat disintegration and enzymatic hydrolysis when going through the small intestine. Unsavory chloramphenicol has about 60% chloramphenicol, so the dose must be increased by 2/3 when taking it. Especially suitable for youngsters to take. Ointment consisting of chloramphenicol 1% can be made use of for the treatment of eye and also skin infections. In farming, it is mainly efficient against plant bacterial conditions, such as rice microbial curse, with strong systemic effect and also safe for plants.

Chloramphenicol Uses

Chloramphenicol has a wide range of activities and is effective against Gram-positive bacteria, including most drug-resistant Staphylococcus aureus, Gram-negative bacteria and anaerobic organisms. It does not work against Pseudomonas aeruginosa or Enterobacter species. For Burkholderia pseudomallei, it has little effect but has been replaced by ceftazidime and meropenem. In the West, the use of chloramphenicol is mainly limited to topical use because of its risk of causing aplastic anemia.

Initially, chloramphenicol was only used to treat typhoid fever, but now there are typhoid bacilli that can resist multiple drugs, showing that chloramphenicol can only inhibit certain bacteria. Chloramphenicol can also be used as second-line therapy for tetracycline-resistant cholera.

Because of its high permeability to CSF (much higher than that of cephalosporins), chloramphenicol is the first choice for treating brain abscesses caused by S. aureus. It is also used in the treatment of brain abscesses caused by various organisms or of unknown origin.

Chloramphenicol can effectively inhibit the three main bacteria causing meningitis: Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae. In the West, chloramphenicol is used to treat meningitis patients allergic to penicillins or cephalosporins. It is suggested that family doctors should be equipped with intravenous preparations of chloramphenicol. In some low-income countries, the World Health Organization also recommends the use of chloramphenicol oil as the first-line treatment of meningitis.
