Angiotensin Receptor Neprilysin Inhibitor LCZ696: a Novel Targeted Therapy for Arterial Hypertension?

The need for novel antihypertensive therapies represents a continuous challenge. LCZ696 is a first-in-class angiotensin receptor neprilysin inhibitor that has been shown to enhance endogenous natriuretic peptide (NP) actions on neurohormonal activation. This effect seems to be additive to that of the renin-angiotensin-aldosterone system (RAAS) suppression, as impressively suggested in the PARADIGM HF study. LCZ696 has been shown to be effective in reducing blood pressure in several small studies; however, its effectiveness and safety remain to be proved in larger studies. This review summarizes the role of RAAS and NP system in the pathophysiology of hypertension and reviews the current data on the antihypertensive effects of LCZ696.
