According to Joyce Oen-Hsiao, MD, associate professor of medicine at Yale School of Medicine: Sacubitril prevents the breakdown of natriuretic peptides, which helps relax blood vessels and promote sodium excretion. Valsartan inhibits the effects of angiotensin II, a hormone that causes blood vessels to constrict and increases blood pressure.
