Specific treatments for angiotensin-converting-enzyme inhibitor (ACE-I) and angiotensin-receptor-blocker (ARB)-induced angioedema exist. Early access to these treatments is challenging because they are expensive and have short shelf lives making it illusory that all emergency department (ED) stock them. The aim of this retrospective study was to define, for each patient with a confirmed ACE-I or ARB-induced angioedema, at which step of the care, the specific treatment was administered. The second objective was to analyse the availability of these treatment in the area around Lyon, France and the factors that may influence it.
