[Drug induced angioedema (ACE-inhibitors and other)]

Angiotensin Converting Enzyme inhibitors (ACE-I) use is a frequent cause of AE and must be suspected systematically in all patients with AE. The risk of AE is increased in: black people, transplanted patients, those who take gliptins or immunosuppressants (mTOR i). Angiotensin converting enzyme inhibitors induced angioedema (ACE-I AE) can occur a few days to several years after the beginning of this treatment and persist a few months after stopping it. ACE-I AE affect mainly the face and particularly the tongue but also the abdomen. ACE-I AE can be life threatening, due to the involvement of the tongue and the larynx. ACE-I AE must be treated as in the hereditary form when life threatening signs are present, with icatibant or C1 inhibitor concentrate. AE can occur in 10% of angiotensin receptor blockers (ARBs) treated patients who had developed ACE-I AE.
