Ecallantide (Kalbitor) vs Teduglutide (Gattex)
An educational, source-based comparison of Ecallantide (Kalbitor) and Teduglutide (Gattex) — how each peptide works, what it's researched for, and what to know before going deeper.
Plasma kallikrein inhibitor for hereditary angioedema.
60-amino-acid recombinant protein that selectively inhibits plasma kallikrein, reducing bradykinin generation during HAE attacks.
- Hereditary angioedema (acute attacks, ≥12 yrs)
- • FDA-approved.
- • Boxed warning: anaphylaxis — administer by healthcare professional.
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.
