ACE-inhibitor induced angioedema

ACE-inhibitor induced angioedema is a non-allergic drug-related side effect. Inhibited bradykinin degradation leads to an unphysiological enhanced bradykinin plasma level with vascular leakage and, consequently, to angioedema. ACE-inhibitor induced angioedema develop rapidly in the head and neck region. Typical sites of manifestation are lips, tongue, and larynx. Novel pharmacotherapies may allow a causal treatment of the ACE-inhibitor induced angioedema in the future.
