WHY is this medicine prescribed?

Aprocitentan is used to treat high blood pressure. Aprocitentan is in a class of medications called endothelin receptor antagonists. It lowers blood pressure by relaxing the blood vessels so the heart does not have to pump as hard.

High blood pressure is a common condition, and when not treated it can cause damage to the brain, heart, blood vessels, kidneys, and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
