The term vasopeptidase means any peptidase able to generate or to inactivate a vasoactive peptide. This term got a more definitive meaning when a new class of drugs, the vasopeptidase inhibitors, was introduced. These drugs are especially represented by the inhibitors of angiotensin-converting enzyme (ACE) and neutral endopeptidase (NEP). ACE is now primarily considered a kininase rather than an angiotensinase and ACE-inhibitors have been used successfully in the treatment of many cardiovascular diseases, including hypertension and heart failure. Preliminary results suggest that the use of NEP inhibitors could also contribute to improve prognosis of cardiovascular diseases. Vasopeptidase inhibitors simultaneously inhibiting both NEP and ACE have shown to be more effective than currently available ACE inhibitors. (Omapatrilat is at present the most clinically advanced in these drugs). However, many side-effects of vasopeptidase inhibitors have been reported, but the most dangerous is angioedema which is potentially life threatening. Since this complication is mediated by bradykinin, and both inhibition of ACE and NEP can produce bradykinin increasing, it has been suggested that the incidence of angioedema due to vasopeptidase inhibitors could be higher compared with that related to ACE-inhibitors. The FDA raised concern about this adverse effect, and the manufacturer decided to withdraw the application temporarily. In order to identify patients at risk of angioedema we have recently shown that low plasma levels of aminopeptidase P, another enzyme which cabolises bradykinin, could indicate a predisposition for development of angioedema in some patients treated with vasoinhibitor drugs.
