What Is Valsartan?

Valsartan is a medication that is taken to treat high blood pressure (hypertension) and certain heart-related conditions.

The drug belongs to a group of angiotensin II receptor blockers which work by blocking the hormone angiotensin II to lower blood pressure.

Valsartan is available in generic form (generic Diovan) as well as under the brand names Diovan and Prexxartan.

How Does Valsartan Work?

Being a receptor blocker, Valsartan works by blocking the effects of the hormone angiotensin. This means it cannot bind to the receptors that are found on blood vessels and other tissues stopping them from restricting and narrowing which helps enhance blood flow and improve blood pressure as well as stimulate aldosterone production.

Valsartan also indirectly reduces the secretion of the hormone aldosterone, which in turn encourages the kidneys to excrete sodium and water, further helping to lower blood pressure.

What Is Valsartan Used For?

Valsartan is used for a variety of different conditions, mainly lowering blood pressure. Through dilating the blood vessels, blood can flow through more easily and is less likely to become blocked.

Other uses for Valsartan include:

• Managing heart failure
• As a treatment post-heart attack to help reduce the risk of further events or complications

• Treating diabetic nephropathy, a kidney disorder common in people with diabetes, usually as part of a broader treatment plan
