Colistin, also known as polymyxin E, is an antibiotic medication used as a last-resort treatment for multidrug-resistant Gram-negative infections including pneumonia.[7][8] These may involve bacteria such as Pseudomonas aeruginosa, Klebsiella pneumoniae, or Acinetobacter.[9] It comes in two forms: colistimethate sodium can be injected into a vein, injected into a muscle, or inhaled, and colistin sulfate is mainly applied to the skin or taken by mouth.[10] Colistimethate sodium[11] is a prodrug; it is produced by the reaction of colistin with formaldehyde and sodium bisulfite, which leads to the addition of a sulfomethyl group to the primary amines of colistin. Colistimethate sodium is less toxic than colistin when administered parenterally. In aqueous solutions, it undergoes hydrolysis to form a complex mixture of partially sulfomethylated derivatives, as well as colistin. Resistance to colistin began to appear as of 2015.[12]

Common side effects of the injectable form include kidney problems and neurological problems.[8] Other serious side effects may include anaphylaxis, muscle weakness, and Clostridioides difficile-associated diarrhea.[8] The inhaled form may result in constriction of the bronchioles.[8] It is unclear if use during pregnancy is safe for the fetus.[13] Colistin is in the polymyxin class of medications.[8] It works by breaking down the cytoplasmic membrane, which generally results in bacterial cell death.[8]

Colistin was discovered in 1947 and colistimethate sodium was approved for medical use in the United States in 1970.[9][8] It is on the World Health Organization's List of Essential Medicines.[14] The World Health Organization classifies colistin as critically important for human medicine.[15] It is available as a generic medication.[16] It is derived from bacteria of the genus Paenibacillus.[10]
