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.
Oxytocin
Oxytocin is synthesised in the hypothalamus and released via the posterior pituitary. Peripherally it binds the oxytocin receptor, a G-protein-coupled receptor, and through the phospholipase-C cascade and calcium release triggers contraction of uterine smooth muscle and milk ejection — the pharmacological basis of the obstetric approval. Centrally, oxytocin acts as a neuromodulator and has been linked to social bonding, trust and modulation of stress and anxiety circuits. Its central effects in humans are mechanistically incompletely understood, particularly because it is unclear to what extent peripherally or intranasally administered oxytocin crosses the blood-brain barrier.

Frequently asked questions
- What is the difference between Icatibant and Oxytocin?
- Icatibant is classified as "Ricerca (altro)", while Oxytocin 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). Oxytocin: Oxytocin is an endogenous nonapeptide hormone of the posterior pituitary. In synthetic form (Pitocin, Syntocinon) it has been approved for decades to induce and augment labour and to control postpartum uterine bleeding. Strictly separate from this is intranasal use to influence social behaviour, trust, anxiety or autism symptoms: this use is unapproved, purely experimental, and yields inconsistent and often negative results in controlled trials. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Icatibant or Oxytocin?
- The highest available evidence level is "RCT sull'uomo" for Icatibant and "RCT sull'uomo" for Oxytocin. 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 Oxytocin in Germany and the United States?
- Germania: Icatibant — Su prescrizione, Oxytocin — Su prescrizione. Stati Uniti: Icatibant — Su prescrizione, Oxytocin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
