VALZAAR 80 HValsartan+HCTZTorrent Pharma. Rx quality 90 (9 x 10) 80/12.5mg Tabs . This drug is used to treat high blood pressure (hypertension). This medication is a combination of two drugs (an angiotensin receptor blocker and a thiazide "water pill"/diuretic). Valsartan blocks the hormone angiotensin thereby relaxing blood vessels, causing them to widen. The thiazide diuretic increases the amount of urine you make, therefore decreasing excess water and salt in your body. High blood pressure reduction helps prevent strokes, heart attacks, and kidney problems.OTHER USES: This .
