Usage of Takhzyro

Takhzyro is a monoclonal antibody that works by reducing the activity of an enzyme that is uncontrolled in people with hereditary angioedema (a rare genetic immune system disorder). Takhzyro is used to prevent attacks of hereditary angioedema (HAE) in people who are at least 2 years old.

People with hereditary angioedema have high levels of a substance called bradykinin, Takhzyro (Lanadelumab-flyo) works by reducing  the level of bradykinin, which helps to prevent the swelling and related symptoms of angioedema.
