Mechanism of action

Colistin acts as a cationic antimicrobial peptide that interacts with the outer membrane of gram-negative bacteria, particularly effective against multidrug-resistant organisms like Pseudomonas aeruginosa and Acinetobacter baumannii. The saline solution serves as a vehicle for delivery and maintains osmotic balance. This combination is typically used for inhalation therapy to treat respiratory infections in hospitalized patients.
