Mechanism of action
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.
Pasireotid
Pasireotide binds more broadly than older somatostatin analogs (SSTR1/2/3/5) with particularly high affinity for SSTR5. This suppresses, among others, ACTH release in Cushing's disease and GH release in acromegaly.

Frequently asked questions
- What is the difference between Icatibant and Pasireotid?
- Icatibant is classified as "Research other", while Pasireotid is classified as "Research other". 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). Pasireotid: Pasireotide is a multireceptor somatostatin analog binding to four of the five somatostatin receptors (especially SSTR5). It is approved for Cushing's disease and acromegaly. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Icatibant or Pasireotid?
- The highest available evidence level is "Human RCT" for Icatibant and "Human RCT" for Pasireotid. 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 Icatibant and Pasireotid in Germany and the United States?
- Germany: Icatibant — Prescription, Pasireotid — Prescription. United States: Icatibant — Prescription, Pasireotid — Prescription. These are factual summaries with source and review date on the individual pages.
