title: [Angioedema induced by ACE inhibitors and angiotensin II-receptor antagonists: analysis of 98 cases].
abstract: Angiooedema has been reported as a rare but in most cases serious adverse effect of ACE inhibitors. Recent reports have indicated that angiotensin II-receptor antagonists may also induce angiooedema. As part of the spontaneous reporting scheme in Switzerland the Swiss Drug Monitoring Centre (SANZ) has received reports on 94 cases of ACE inhibitor-induced and 4 cases of angiotension II-receptor antagonist-induced angiooedema. These 98 spontaneously reported cases were analysed in detail. 28 cases were classified as serious and in three patients intubation was even required. In 35% of cases angiooedema was induced within the first week of therapy and in 64% within the first year. In one case the angio-oedema displayed latency of 8 years. Latency of this duration shows that this adverse drug reaction (ADR) may be hard to detect. In 45 of the 98 cases the oedema persisted for more than one day (maximum 2 months), although in some instances the patients continued ACE-inhibitor therapy. In 25 cases the oedema recurred, in one instance as many as 20 times. In rare cases angiooedema may also be induced by angiotensin II-receptor antagonists, although in such instances the course of the oedema was usually milder. In two of the four reported cases angiooedema recurred after switching from an ACE inhibitor to an angiotensin II-receptor antagonists. The four reported cases from Switzerland showed a similar profile when compared with 25 internationally documented cases. Our data indicate that angiooedema is a specific ACE inhibitor ADR. A protracted latency period may be observed and recurrence of oedema is frequent. Angiotensin II-receptor antagonist-induced angiooedema may also occur in rare instances.
