Angioedema associated with angiotensin-converting enzyme inhibitors

A review of two cases of angioedema associated with therapeutic doses of the angiotensin-converting enzyme inhibitor enalapril are presented along with a review of the relevant literature. Although angioedema of the facial and oral pharyngeal regions is a relatively rare occurrence with the use of ACE inhibitors, recognition of these agents as the cause of such a condition, when subacute, can lead to a rapid cure. Knowledge of these effects may also be helpful in the management of an acute clinical manifestation and, as importantly, may help prevent a recurrent episode due to the ill-guided continuation of the drug.
