MedKoo CAT#: 525780

CAS#: 167305-00-2

Description: Omapatrilat is a novel antihypertensive agent that inhibits both neutral endopeptidase (NEP) and angiotensin converting enzyme. NEP inhibition results in elevated natriuretic peptide levels, promoting natriuresis, diuresis, vasodilation, and reductions in preload and ventricular remodeling. The drug was promoted for possible uses in congestive heart failure.
