How Takhzyro (lanadelumab) works
Takhzyro (lanadelumab) is a monoclonal antibody that's in a group of medications called plasma kallikrein inhibitors. It blocks the activity of a protein in your blood called plasma kallikrein.
Plasma kallikrein is more active in people with hereditary angioedema (HAE) and raises the production of bradykinin, a substance that's responsible for pain and swelling. By lowering plasma kallikrein activity, Takhzyro (lanadelumab) can help prevent pain and swelling attacks in people with HAE.
