Werkingsmechanisme

Sekretin

Secretin binds the Gs-coupled secretin receptor (SCTR) on pancreatic duct cells, opens CFTR chloride channels and triggers secretion of bicarbonate-rich pancreatic fluid and bile flow.

Selank

Selank is a glyproline-tuftsin analog. Proposed mechanisms include modulation of the GABAergic system, effects on serotonin bioavailability, and influence on enkephalinases. Animal studies show anxiolytic and neuroprotective markers; a clear receptor target is not established.

Frequently asked questions

What is the difference between Sekretin and Selank?: Sekretin is classified as "Onderzoek (overig)", while Selank is classified as "Onderzoek (overig)". Sekretin: Secretin is a 27-amino-acid hormone that regulates pancreatic bicarbonate secretion. As ChiRhoStim it is FDA-approved as a diagnostic agent (pancreatic function test, gastrinoma test, secretin-enhanced MRCP). Selank: Synthetic heptapeptide derived from natural tuftsin. Approved as an anxiolytic (Selank) in Russia and some CIS states. Western phase-3 trials are absent; efficacy assessment relies on Russian research literature. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Sekretin or Selank?: The highest available evidence level is "Humane studie" for Sekretin and "Humane studie" for Selank. 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 Sekretin and Selank in Germany and the United States?: Duitsland: Sekretin — Op recept, Selank — Niet goedgekeurd. Verenigde Staten: Sekretin — Op recept, Selank — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
