Last-resort lipopeptide antibiotic for multidrug-resistant Gram-negatives.
Cationic cyclic lipopeptide that disrupts the outer membrane of Gram-negative bacteria by binding lipid A of LPS, causing membrane permeability and cell death.
- Carbapenem-resistant Acinetobacter, Klebsiella, Pseudomonas
- • FDA-approved.
- • Nephrotoxicity and neurotoxicity dose-limiting.
