ReviewIcatibant as acute treatment for hereditary angioedema in adults.
Hereditary angioedema with C1 inhibitor deficiency (C1-INH-HAE) is a rare disease, characterized by recurrent, unpredictable episodes of cutaneous and/or mucosal edema. Bradykinin, released by the activation of the contact system, binds to bradykinin B2 receptors on the endothelial cell surface to enhance vascular permeaility, which leads to angioedema. ⋯ C1-INH-HAE therapy is aimed at the inhibition of bradykinin release, as well as at the blockage of its effects mediated by its receptor. Three controlled trials, three open-label extensions, and two open-label studies, and a prospective, observational study have confirmed the safety and efficacy of the bradykinin B2 receptor antagonist, icatibant administered as acute treatment for HAE attacks in adult patients with C1-INH-HAE. Expert commentary: The ready-to-use, pre-filled syringes of icatibant can be self-administered easily, effectively, safely and, importantly, conviently. - This has resulted in patients being able to quickly treat an attack and realize a dramatic change for the better in their lives.
