Much has been written about hereditary angioedema (HAE) in recent literature; however, the prevalence of angiotensin-converting enzyme inhibitor-induced angioedema (ACEiIA) far exceeds that of HAE. Similarly, multiple therapies have been developed for HAE, yet no definitive therapy is available for ACEiIA. In this article, we discuss the mechanism, prevalence, pathophysiology, and management of ACEiIA, with focus on newer therapies recently approved for HAE and how they may be effective for ACEiIA.
