Diovan⁚ A Comprehensive Guide
Introduction
Diovan, also known by its generic name valsartan, is a prescription medication primarily used to treat high blood pressure (hypertension) in adults and children aged 6 to 16. It belongs to a class of drugs called angiotensin II receptor blockers (ARBs).
How Does Diovan Work?
Angiotensin II is a hormone that causes blood vessels to constrict, raising blood pressure. Diovan blocks the action of angiotensin II, allowing blood vessels to relax and widen, thereby lowering blood pressure.
