NCIt definition : A vasopeptidase inhibitor with antihypertensive activity. Omapatrilat exerts its effect
by inhibiting angiotensin converting enzyme (ACE) and neutral endopeptidase (NEP).
ACE inhibition results in inhibition of the renin-angiotensin-aldosterone system thereby
leading to the reduction of vasoconstriction. Inhibition of NEP leads to the inhibition
of hydrolyzation of a number of endogenous vasoactive peptides, such as bradykinin
and substance P and as NEP is the principal enzyme degrading natriuretic peptides,
NEP inhibition also results in an increase in natriuretic peptidase circulation. Ultimately
both effects result in blood vessel relaxation.;
