Concomitant medication in patients with bradykinin‐mediated angioedema – there's more than ACE inhibitors

Abstract

SummaryBradykinin‐mediated angioedema is a rare, non‐allergic, potentially life‐threatening disease. ACE inhibitor‐induced angioedema and hereditary angioedema (HAE) are the two most common presentations. Therapeutic options, pathophysiology and diagnosis continue to be investigated, with considerable progress in HAE over the last few decades. For all patients with bradykinin‐mediated angioedema, there are several medications that should be avoided or administered with caution. Some of the triggering medications are well known, while others are suspected or of unknown significance. A common denominator is that there is no approved therapy for bradykinin‐mediated angioedema as a drug side effect. Some medications, such as tissue plasminogen activator, have a higher incidence of angioedema with potential airway compromise than ACE inhibitors, although this fact is widely underappreciated. In this review, we aim to summarize what is currently known and recommended about concomitant medication in HAE patients and the interaction of other bradykinin‐influencing drugs.
