Colistin (Polymyxin E) vs Enfuvirtide (Fuzeon)
An educational, source-based comparison of Colistin (Polymyxin E) and Enfuvirtide (Fuzeon) — 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.
36-amino-acid peptide that binds the gp41 subunit of HIV-1 envelope, blocking the conformational change required for viral-host membrane fusion and cell entry.
- Treatment-experienced HIV-1 infection
- • FDA-approved.
- • Injection-site reactions nearly universal.
