Sacubitril is an antihypertensive drug used in combination with valsartan. The combination drug, valsartan/sacubitril, known during trials as LCZ696 and marketed under the brand name, Entresto, is a treatment for heart failure.
Sacubitril (AHU377) is a prodrug inhibitor of the membrane metallo-endopeptidase neprilysin. Sacubitril forms half of the heart failure combination drug LCZ696, along with the angiotensin-receptor blocker Valsartan. Sacubitril (AHU377) is cojnverted by esterases into the active inhibitor LBQ657, which prevents neprilysin′s degradation of atrial and brain natriuretic peptide, two blood pressure lowering peptides. The AHU377 valsartan combination drug LCZ696 showed a reduction in the risk of cardiovascular death of 20% compared to the standard ACE inhibitor enalapril, and also a 21% drop in the risk of hospitalization.
