Description_x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ 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.
