Abstract

Inhibitors of angiotensin converting enzyme may rarely cause an angioneurotic oedema of the upper aerodigestive tract. The pathomechanism of this side effect depends on an interaction of the drug with hormones regulating the vascular resistance such as the kallikrein kinin system and the prostaglandin system. Anglo-oedema is characterised by subcutaneous or submucosal swelling, which preferably affects the lips, the soft palate, the tongue and the larynx. Pathomechanisms, differential diagnosis and treatment of ACE-inhibitor induced oedema of the upper aerodigestive tract are described by means of 3 case reports.
