What is Valsartan and Hydrochlorothiazide?
Valsartan and Hydrochlorothiazide is a combination medication used to treat high blood pressure (hypertension). It contains two active ingredients:
- Valsartan (an angiotensin II receptor blocker - ARB)

Together, they help lower blood pressure more effectively than either medicine alone.

This combination works in two different ways:
1. Valsartan
- Relaxes blood vessels

- Reduces fluid buildup in the body
- Lowers blood pressure volume
Combined effect = better and more stable blood pressure control
