Mechanism of action

Colistin is a polymyxin antibiotic that acts as a cationic detergent, inserting into the outer and inner membranes of gram-negative bacteria. This disrupts membrane integrity and leads to leakage of cellular contents and bacterial cell death. It is primarily used against multidrug-resistant gram-negative organisms when other antibiotics have failed.
