Valsartan belongs to the class of medicines called angiotensin II inhibitors. It is used to treat high blood pressure (hypertension). It is also used to treat heart failure and it can lower the need for hospitalization that happens from heart failure. Valsartan can also treat left ventricular dysfunction after a heart attack. Left ventricular dysfunction occurs when the left ventricle (the main pumping chamber of the heart) stiffens and enlarges and can cause the lungs to fill with blood .
High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled.
Valsartan works by blocking the action of a substance in the body that causes blood vessels to tighten. As a result, valsartan relaxes blood vessels. This lowers blood pressure.
valsartan is available only with your doctor's prescription.
