An educational, source-based comparison of Colistin (Polymyxin E) and Nesiritide (Natrecor) — 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.
Recombinant BNP for acute decompensated heart failure.
Recombinant human B-type natriuretic peptide that binds natriuretic peptide receptors to cause vasodilation, natriuresis, and reduction of preload/afterload in decompensated heart failure.
- Acute decompensated heart failure
- • FDA-approved.
- • Hypotension common; renal monitoring needed.
