Icatibant (Firazyr) vs Teduglutide (Gattex)

An educational, source-based comparison of Icatibant (Firazyr) and Teduglutide (Gattex) — how each peptide works, what it's researched for, and what to know before going deeper.

Bradykinin Antagonist · Immunology
Icatibant (Firazyr)

Bradykinin B2 receptor antagonist for hereditary angioedema attacks.

Mechanism

Synthetic decapeptide that competitively blocks the bradykinin B2 receptor, halting the vascular leak that drives HAE swelling attacks.

Research areas
  • Hereditary angioedema (acute attacks)
Considerations
  • FDA-approved.
  • Injection-site reactions very common.

GLP-2 Analog · Gastrointestinal
Teduglutide (Gattex)

GLP-2 analog for short bowel syndrome dependent on parenteral support.

Mechanism

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.

Research areas
  • Short bowel syndrome with intestinal failure
  • Reduction of parenteral nutrition dependence
Considerations
  • FDA-approved.
  • Colorectal polyp surveillance required.
  • Risk of intestinal obstruction and biliary/pancreatic disease.
