Colistin (Polymyxin E) vs Teduglutide (Gattex)
An educational, source-based comparison of Colistin (Polymyxin E) and Teduglutide (Gattex) — 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.
GLP-2 analog for short bowel syndrome dependent on parenteral support.
Recombinant analog of glucagon-like peptide-2 with alanine→glycine substitution at position 2, resisting DPP-IV degradation; promotes intestinal mucosal growth, villus height, and absorptive capacity.
- Short bowel syndrome with intestinal failure
- Reduction of parenteral nutrition dependence
- • FDA-approved.
- • Colorectal polyp surveillance required.
- • Risk of intestinal obstruction and biliary/pancreatic disease.
