Asp-Tyr(SO3H)-Met-Gly-Trp-Met-Asp-Phe-NH2Mechanism of action
Lanreotid
Lanreotide activates somatostatin receptors (chiefly SSTR2, additionally SSTR5), thereby suppressing the release of growth hormone, IGF-1 and various gastrointestinal and neuroendocrine hormones. It is metabolically far more stable than natural somatostatin.
Sincalide
Sincalide activates CCK receptors, triggering gallbladder contraction and pancreatic enzyme secretion. This effect is used diagnostically to measure the gallbladder ejection fraction (e.g. in HIDA scintigraphy).

Frequently asked questions
- What is the difference between Lanreotid and Sincalide?
- Lanreotid is classified as "Research other", while Sincalide is classified as "Research other". Lanreotid: Lanreotide is a synthetic cyclic octapeptide analog of somatostatin. It binds preferentially to the somatostatin receptors SSTR2 and SSTR5 and is approved for treating acromegaly and certain neuroendocrine tumours. Sincalide: Sincalide is the synthetic C-terminal octapeptide of the hormone cholecystokinin (CCK-8). As Kinevac it is FDA-approved to stimulate gallbladder contraction for diagnostic imaging. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Lanreotid or Sincalide?
- The highest available evidence level is "Human RCT" for Lanreotid and "Human trial" for Sincalide. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Lanreotid and Sincalide in Germany and the United States?
- Germany: Lanreotid — Prescription, Sincalide — Unclear. United States: Lanreotid — Prescription, Sincalide — Prescription. These are factual summaries with source and review date on the individual pages.
