How it works

Bradykinin, the swelling molecule, rebuilt to block its own B2 receptor, so vessels stop leaking. For hereditary angioedema.

What it's made of

10 amino acids: bradykinin (9), the molecule that causes swelling, with one more in front and five non-natural pieces. That way it stops activating its receptor, blocks it and lasts longer.

What it's for

Prescribed for

Acute attacks of hereditary angioedema caused by missing or faulty C1 inhibitor.
