Popular FAQ

What is Takhzyro’s mechanism of action?

Takhzyro’s mechanism of action involves blocking the activity of plasma kallikrein, a protein in the body that can lead to hereditary angioedema (HAE) attacks. Inhibiting kallikrein helps to slow down the release of bradykinin, an inflammatory peptide, and reduce the number of attacks. HAE is a rare genetic condition that causes swelling in areas such as the stomach, limbs, face and throat.
