Sincalide (Kinevac) vs Teduglutide (Gattex)
An educational, source-based comparison of Sincalide (Kinevac) and Teduglutide (Gattex) — how each peptide works, what it's researched for, and what to know before going deeper.
Synthetic C-terminal octapeptide of cholecystokinin for gallbladder imaging.
Synthetic CCK-8 that binds CCK-A receptors on gallbladder smooth muscle, triggering contraction; used to assess gallbladder ejection fraction in cholescintigraphy.
- Gallbladder ejection fraction (HIDA scan)
- Pancreatic secretion testing
- Small bowel transit imaging
- • FDA-approved.
- • Abdominal cramping, nausea, diarrhea common; contraindicated in suspected gallstone obstruction.
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.
