What Is Diovan (Valsartan)?

Diovan is a brand name for the prescription medication valsartan. It belongs to a class of drugs known as angiotensin II receptor blockers (ARBs). Valsartan is commonly used to treat high blood pressure (hypertension) and heart failure and to improve the chances of living longer after a heart attack.

How Does It Work?

Valsartan, the active ingredient in Diovan, works by selectively blocking angiotensin II type 1 receptors, which are present in various tissues, including blood vessels. Angiotensin II is a powerful vasoconstrictor that narrows blood vessels and raises blood pressure. Diovan prevents angiotensin II from binding to its receptors, resulting in vasodilation, reduced peripheral resistance, and lowered blood pressure. Furthermore, it proves effective in treating heart failure by alleviating the heart’s workload and enhancing its pumping capability.

Diovan Dosage and Storage Instructions


Diovan is available in different forms, including oral tablets and oral solutions. The tablets come in various strengths, such as:

  • Diovan 40 mg tablets 
  • Diovan 80 mg tablets
  • Diovan 160 mg tablets
  • Diovan 320 mg tablets

The dosage prescribed by a healthcare professional depends on the specific condition being treated and the individual patient’s needs. Typically, Diovan is taken once or twice daily, with or without food. It is crucial to follow the prescribed dosage and administration instructions provided by the healthcare provider to ensure the Diovan 160 mg price and effectiveness.

How to Store?

Diovan should be stored at room temperature, away from excessive heat and moisture. It is advisable to keep Diovan in its original packaging and out of reach of children. Avoid storing the medication in the bathroom, as the humidity can affect its stability. Additionally, always check the Diovan 160 mg price and expiration date before using it.
