Ekterly is the first and only oral, on-demand therapy for hereditary angioedema (HAE) attacks in patients aged 12 and older. It works by inhibiting plasma kallikrein, preventing excessive bradykinin production to reduce swelling rapidly. Approved in the U.S. and U.K. in 2025, Ekterly offers fast relief, convenient oral dosing, and a major advance over injectable treatments, giving patients greater independence and control during acute HAE episodes.
