Vasopeptidase inhibitors
Giuseppe A Sagnella

Vasopeptidase inhibitors are a new class of drugs that have dual inhibitory effects on two key enzymes involved in the metabolism of vasoactive peptides. Essentially, they inhibit angiotensin-converting enzyme (ACE), thereby blocking the generation of angiotensin II (Ang II); at the same time they prevent the breakdown of natriuretic peptides by the enzyme neutral endopeptidase. The combination of reduction of Ang II on a background of increased natriuretic peptide activity has several potential advantages for the treatment of cardiovascular and renal disease and in particular, hypertension and congestive heart failure (CHF). Several vasopeptidase inhibitors, such as sampatrilat, fasidotril, gemopatrilat and omapatrilat (VanlevTM, the most clinically developed vasopeptidase inhibitor to date) are under intensive clinical investigation. Recent clinical trials have demonstrated effective antihypertensive activity in hypertension, independent of age, renin and salt status or ethnic origin, and have also highlighted the potential for vasopeptidase inhibition as a new therapeutic modality for the treatment of CHF. Moreover, ongoing research suggests that this new class of drugs may be an important approach, not only for the treatment of hypertension and of conditions associated with overt volume overload but also for ischaemic heart disease.
