These medications result in increased levels of circulating bradykinins. This case illustrates the result of a local traumatic event to the upper lip, presumably causing marked bradykinin release in a patient who was taking an ACE inhibitor. The local release of bradykinin from trauma, in addition to decreased bradykinin catabolism secondary to ACE inhibitor therapy, resulted in angioedema predominantly in the upper lip. The angioedema resolved with discontinuation of the ACE inhibitor.
