Vasopeptidase inhibition: a new direction in cardiovascular treatment

Abstract

The development of new antihypertensive agents is becoming even more important. We need better blood pressure control and also agents that treat hypertension as a disease of the vascular endothelium. Recently, it has been shown that blocking the renin-angiotensin system with angiotensin converting enzyme (ACE) inhibitors reduces blood pressure and decreases the incidence of vascular disease. Another peptide system, the natriuretic peptide system, has also been shown to be important in blood pressure control and volume homeostasis. Because ACE and neutral endopeptidase, the enzyme responsible for the degradation of the natriuretic peptides, are both zinc metalloproteases, new pharmaceuticals that inhibit both enzymes have been developed. The first of these, omapatrilat, has been shown to be an effective antihypertensive agent and to have great potential for treating congestive heart failure.
