Valsartan reduces high blood pressure. The active ingredient valsartan is a type of medicine called an angiotensin II receptor antagonist, also referred to as an angiotensin II blocker. Valsartan causes the peripheral blood vessels to widen, which lowers the pressure in the blood vessels. 

What is Valsartan? 

Valsartan is a blood pressure reducer. It relaxes the muscles around the blood vessels, causing the blood vessels to widen. This means there is more space and less resistance in these blood vessels. As a result, the pressure in the blood vessels is lowered. 

When is Valsartan used? 

Valsartan primarily prescribed to treat the following conditions: 

  • High blood pressure. Most people with high blood pressure will not experience any symptoms. Nevertheless, having uncontrolled high blood pressure can be dangerous. When blood pressure is elevated it can thicken and narrow blood flow and damage the arteries, increasing the risk of cardiovascular disease. Valsartan is used to lower the blood pressure and thus reduces these health risks. 
  • Heart failure. Heart failure means that the heart is unable to pump blood around the body properly. This can lead to various symptoms, including shortness of breath, fatigue and an increase in lung fluid. Valsartan Improves the condition of the heart and lowers blood pressure. As a result, heart function will improve. 
  • Poorly functioning heart. Valsartan is also used to treat adults with a poorly functioning heart as result of a recent heart attack in which part of the heart muscle dies. Valsartan helps the heart to pump the blood around the body and so reduces the chance of additional heart problems caused by a heart attack.
