An educational, source-based comparison of Colistin (Polymyxin E) and Telavancin (Vibativ) — how each peptide works, what it's researched for, and what to know before going deeper.
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.
Lipoglycopeptide for complicated skin infections and HABP/VABP.
Semisynthetic vancomycin derivative with a lipophilic side chain that inhibits peptidoglycan synthesis and depolarizes the bacterial cell membrane, active against MRSA and other Gram-positives.
- Complicated skin and skin structure infections
- Hospital-acquired and ventilator-associated bacterial pneumonia caused by S. aureus
- • FDA-approved.
- • Boxed warning: nephrotoxicity, increased mortality in pre-existing moderate/severe renal impairment HAP.
- • Avoid in pregnancy.
