This product contains3 medications: amlodipine, valsartan, and hydrochlorothiazide. Amlodipine is a calcium channel blocker, and valsartan is an angiotensin receptor blocker(ARB).

Hydrochlorothiazide is called a "water pill" (diuretic) and causes your body to get rid of extra salt and water by making more urine.
