Description: Avoralstat, also known as BCX-4161, is a potent and orally active Kallikrein inhibitor and Bradykinin inhibitor. Avoralstat may be potentially useful for treatment for Hereditary angioedema. Avoralstat inhibits plasma kallikrein and suppresses bradykinin production. Bradykinin is the mediator of acute swelling attacks in HAE patients.
