What is the generic name for the brand Diovan?

The generic name for the brand Diovan is Valsartan. This medication is classified as an angiotensin II receptor blocker (ARB), which is commonly used to treat high blood pressure and heart failure. It works by relaxing blood vessels, thereby lowering blood pressure and increasing the supply of blood and oxygen to the heart.

Valsartan is specifically designed to prevent the effects of certain hormones that can constrict blood vessels, making it effective in managing cardiovascular conditions. This mechanism of action is fundamental to its therapeutic effects, distinguishing it from other medications in the ARB class.

In the context of the other medications listed—Candesartan, Losartan, and Irbesartan—while they all belong to the same class and are used for similar indications, they are different drugs with their own distinct molecular characteristics and branding. This makes Valsartan the correct answer in identifying the generic name for the brand Diovan.
