Valsartil 40 mg is an oral medication containing Valsartan, an angiotensin II receptor blocker (ARB) used primarily to treat high blood pressure (hypertension) and heart failure, and to improve survival after a heart attack. Each tablet provides 40 mg of Valsartan, which works by relaxing blood vessels, allowing blood to flow more easily and helping to lower blood pressure. This reduction in blood pressure helps prevent strokes, heart attacks, and kidney problems. Valsartil may also be prescribed to protect kidney function in patients with diabetes. It is typically taken once or twice daily, with or without food, depending on the patient's medical condition and response to treatment.
