Actions and spectrum:
colistin is an antibiotic that belongs to the class of polymyxins. It is used to treat infections which are caused by Gram-ve bacteria, including Pseudomonas aeruginosa, Acinetobacter baumannii, and Klebsiella pneumoniae.
colistin is a last-resort antibiotic and is typically used only when other antibiotics are ineffective or not available. It acts by binding to the bacterial cell membrane and disrupting its structure, leading to bacterial death.
