Other names: Acquired angioedema
ACE-I induced angioedema

Drug-induced angioedema is a known complication of the use of angiotensin-converting enzyme (ACE) inhibitors, angiotensin II antagonists (ARBs), and Angiotensin-Neprilysin Inhibitor LCZ969.[1]: 120  The angioedema appears to be dose dependent as it may resolve with decreased dose.[1]: 120 

Signs and symptoms

Angioedema presents itself as an abrupt onset of non-pitting, non-itchy swelling that involves the mucosal layers. Some common locations of angioedema are the face, particularly the lips and around the eyes, hands and feet, and genitalia.[2] A rare, yet serious complication is one inside the abdomen, the symptom usually being severe stomach upset, which is much less obvious than the other locations.[3]

Risk factor

Some common ACE Inhibitors are:

Some common ARBs are:


The diagnosis of drug-induced angioedema is done via, but not limited to:[4]


The treatment for this induced condition may include emergency medication as well as epinephrine.[4]


The chance of drug-induced angioedema is extremely uncommon, however, as studies show incidence of less than 1%.[5] The reason this adverse effect may occur is due to the build-up of bradykinin, a vasodilator. This causes blood vessels to dilate and allow for fluid buildup in the mucosal surfaces.
