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.
Teduglutid
Teduglutide activates the GLP-2 receptor, promoting growth and regeneration of small-intestinal villi, increasing nutrient and fluid absorption and thereby reducing dependence on parenteral nutrition. The glycine substitution at position 2 makes it resistant to rapid breakdown by DPP-4.

Frequently asked questions
- What is the difference between Calcitonin (Lachs) and Teduglutid?
- Calcitonin (Lachs) is classified as "Ricerca (altro)", while Teduglutid 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. Teduglutid: Teduglutide is a DPP-4-resistant analog of GLP-2 (glucagon-like peptide-2). It promotes growth and function of the intestinal mucosa and is approved for treating short bowel syndrome. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Calcitonin (Lachs) or Teduglutid?
- The highest available evidence level is "RCT sull'uomo" for Calcitonin (Lachs) and "RCT sull'uomo" for Teduglutid. 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 Teduglutid in Germany and the United States?
- Germania: Calcitonin (Lachs) — Su prescrizione, Teduglutid — Su prescrizione. Stati Uniti: Calcitonin (Lachs) — Su prescrizione, Teduglutid — Su prescrizione. These are factual summaries with source and review date on the individual pages.
