colistin sulfate

Description:
Colistin sulfate, with the CAS number 1264-72-8, is an antibiotic that belongs to the polymyxin class of antibiotics, primarily used to treat infections caused by Gram-negative bacteria. It is derived from the bacterium Bacillus polymyxa and is known for its effectiveness against multidrug-resistant strains. Colistin sulfate is a complex mixture of polypeptides, with colistin A and colistin E being the most prominent components. The substance is characterized by its amphipathic nature, allowing it to disrupt bacterial cell membranes, leading to cell death. Colistin sulfate is typically administered via injection or inhalation, as it is poorly absorbed from the gastrointestinal tract. Its use has been limited due to potential nephrotoxicity and neurotoxicity, prompting careful monitoring during treatment. Despite these concerns, colistin sulfate has regained attention in recent years due to the rise of antibiotic-resistant infections, making it a critical option in the antimicrobial arsenal. Its formulation as a sulfate salt enhances its solubility and stability, facilitating its use in clinical settings.
