Valsartan

Valsartan is a medication commonly used to manage high blood pressure and certain heart conditions. It works by helping to relax blood vessels, making it easier for the heart to pump blood.

This medication is often prescribed to adults who need to control their blood pressure or improve heart function after a heart attack.

Information about Valsartan

Valsartan Uses

Valsartan is primarily used to address cardiovascular conditions. It is often prescribed for:

High blood pressure (hypertension)
Heart failure

How Valsartan Works

Valsartan belongs to a class of drugs known as angiotensin II receptor blockers (ARBs). It works by blocking the action of a substance in the body that causes blood vessels to tighten.

By preventing this tightening, Valsartan helps blood vessels relax and widen, which lowers blood pressure and improves blood flow.

This mechanism also reduces the workload on the heart, which can be beneficial for patients with heart failure.
