LCZ696 (Sacubitril/Valsartan), ti o ni Valsartan (ARB) ati Sacubitril (AHU377) ni 1: 1 molar ratio, jẹ ẹya akọkọ-ni-kilasi, ẹnu bioavailable, ati meji-angiotensin receptor-neprilysin (ARN) inhibitor fun haipatensonu. ati ikuna ọkan [1][2][3].LCZ696 ṣe atunṣe cardiomyopathy dayabetik nipasẹ didi iredodo, aapọn oxidative ati apoptosis.

LCZ696 jẹ akọkọ ni kilasi ARNi (angiotensin receptor neprilysin inhibitor) ti o ni awọn ẹya anionic ti AR valsartan ati prodrug neprilysin inhibitor AHU377 (1: 1 ratio) fun ikuna ọkan ati haipatensonu.
