What Are Sacubitril/Valsartan (Entresto)?
Sacubitril/valsartan, known by the brand name Entresto,® is an Angiotensin-Receptor Neprilysin Inhibitor (ARNI). It is a new drug combining a neprilysin inhibitor and an angiotensin II receptor blocker (ARB).1-2 Sacubitril/valsartan is indicated to reduce the risk of cardiovascular death and hospitalization for heart failure in adult patients with chronic heart failure. Benefits are most clearly evident in patients with left ventricular ejection fraction (LVEF) below normal.2
Sacubitril/valsartan helps lower the risk of hospitalization and death from worsening heart failure symptoms.1-2 It is prescribed in place of an ACE inhibitor/ARB.2 It is also indicated for the treatment of symptomatic heart failure with left ventricular systolic dysfunction in children over age one.2
What are the ingredients in sacubitril/valsartan?
The active ingredients are sacubitril and valsartan.2
How does sacubitril/valsartan work?
The drug combination contains sacubitril and valsartan, two medicines that work in different ways. Valsartan is an ARB that has been used in heart failure treatment for years. Angiotensin II receptor blockers (ARBs) are a type of vasodilator, a drug that widens blood vessels to lower blood pressure, improve blood flow, and decrease the workload on the heart.1-3 They do this by blocking angiotensin II, a hormone in the body that acts as a vasoconstrictor, causing the blood vessels to narrow (constrict).
Sacubitril is a new medicine that is only found in the Entresto brand. Sacubitril is a neprilysin inhibitor that prevents the breakdown of certain vasoactive peptides in the body causing the blood vessels to widen. Together the medicines work to relax blood vessels and improve blood flow to help a weakened and enlarged heart to pump more effectively.1-2
What are the possible side effects of sacubitril/valsartan?

Common side effects include coughing, dizziness, and lightheadedness. Some people experience lower blood pressure (hypotension), increased potassium (hyperkalemia), and increased serum creatinine levels. This is not a complete list of side effects.1-3
