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.
Bremelanotide
Bremelanotide is a cyclic peptide that binds non-selectively to melanocortin receptors (MC1R through MC5R) — with highest affinity at MC4R in the central nervous system. The precise role of MC4R activation in sexual behaviour is not fully understood; animal data show effects on hypothalamic circuits. Peripheral effects (blood pressure, hyperpigmentation) are attributed to MC1R/MC2R.

Frequently asked questions
- What is the difference between Icatibant and Bremelanotide?
- Icatibant is classified as "Ricerca (altro)", while Bremelanotide is classified as "Ricerca (altro)". 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). Bremelanotide: Synthetic cyclic heptapeptide acting as a non-selective melanocortin-receptor agonist. FDA-approved in 2019 as Vyleesi for hypoactive sexual desire disorder (HSDD) in pre-menopausal women. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Icatibant or Bremelanotide?
- The highest available evidence level is "RCT sull'uomo" for Icatibant and "RCT sull'uomo" for Bremelanotide. 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 Bremelanotide in Germany and the United States?
- Germania: Icatibant — Su prescrizione, Bremelanotide — Non approvato. Stati Uniti: Icatibant — Su prescrizione, Bremelanotide — Su prescrizione. These are factual summaries with source and review date on the individual pages.
