Meccanismo d'azione
Calcitonin (Lachs)
Salmon calcitonin binds the calcitonin receptor, which is particularly densely expressed on bone-resorbing osteoclasts. The literature describes that receptor activation inhibits osteoclast activity and motility, thereby reducing bone resorption. This results in reduced release of calcium and phosphate from bone into the blood, which is regarded as the mechanistic basis for the calcium-lowering effect. The salmon variant binds the receptor more strongly and for longer than human calcitonin, which explains its higher potency. Central nervous system mechanisms are additionally discussed in relation to its pain effect in fractures, the basis of which is regarded in the literature as not fully elucidated.
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.

Frequently asked questions
- What is the difference between Calcitonin (Lachs) and Sekretin?
- Calcitonin (Lachs) is classified as "Ricerca (altro)", while Sekretin is classified as "Ricerca (altro)". Calcitonin (Lachs): Salmon calcitonin is a synthetically produced 32-amino-acid peptide hormone that corresponds to the body's own calcitonin but exhibits higher biological potency than the human hormone. In the scientific literature it is studied in the context of inhibiting osteoclast-mediated bone resorption and lowering elevated calcium levels. It was historically broadly approved for the treatment of postmenopausal osteoporosis; following European safety reviews, however, its use was restricted. 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). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Calcitonin (Lachs) or Sekretin?
- The highest available evidence level is "RCT sull'uomo" for Calcitonin (Lachs) and "Studio sull'uomo" for Sekretin. 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 Calcitonin (Lachs) and Sekretin in Germany and the United States?
- Germania: Calcitonin (Lachs) — Su prescrizione, Sekretin — Su prescrizione. Stati Uniti: Calcitonin (Lachs) — Su prescrizione, Sekretin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
