Werkingsmechanisme
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.
Icatibant
Icatibant competitively blocks the bradykinin B2 receptor. Because bradykinin mediates the vascular permeability, swelling and pain typical of hereditary angioedema, the blockade interrupts the acute attack.

Frequently asked questions
- What is the difference between Calcitonin (Lachs) and Icatibant?
- Calcitonin (Lachs) is classified as "Onderzoek (overig)", while Icatibant is classified as "Onderzoek (overig)". 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. Icatibant: Icatibant is a synthetic decapeptide and selective antagonist of the bradykinin B2 receptor. It is approved to treat acute attacks of hereditary angioedema (HAE). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Calcitonin (Lachs) or Icatibant?
- The highest available evidence level is "Humane RCT" for Calcitonin (Lachs) and "Humane RCT" for Icatibant. 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 Icatibant in Germany and the United States?
- Duitsland: Calcitonin (Lachs) — Op recept, Icatibant — Op recept. Verenigde Staten: Calcitonin (Lachs) — Op recept, Icatibant — Op recept. These are factual summaries with source and review date on the individual pages.
