Application

Colistin sodium methanesulfate is used to permeabilize bacterial cell membranes and to study mannose-resistant haemagglutination.

Biochem/physiol Actions

Colistin sodium methanesulfate is a cyclopolypeptide antibiotic with endotoxin-binding capacity Colistin′s activity stems from the hydrophobic and hydrophillic regions. They solubilze the cytoplasmic membrane which contributes to the bactericidal effect .
Mode of Action: Binds to lipids on the cell cytoplasmic membrane of Gram-negative bacteria and disrupts the cell wall integrity.
Antimicrobial spectrum: Gram-negative bacteria.

Expert review of anti-infective therapy, 6(5), 593-600 (2008-10-14)
Despite the constantly increasing need for new antimicrobial agents, antibiotic drug discovery and development seem to have greatly decelerated in recent years. Presented with the significant problem of advancing antimicrobial resistance, the global scientific community has attempted to find alternative

Infections caused by multidrug-resistant gram-negative bacteria have caused a resurgence of interest in colistin. To date, information about pharmacokinetics of colistin is very limited in critically ill patients, and no attempts have been made to evaluate its concentration in BAL.

With increasing clinical emergence of multidrug-resistant Gram-negative pathogens and the paucity of new agents to combat these infections, colistin (administered as its inactive prodrug colistin methanesulfonate [CMS]) has reemerged as a treatment option, especially for critically ill patients. There has
