Description

Biochem/physiol Actions

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.

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 .

Packaging
