Extor Tab is a medication formulated to help treat high blood pressure. The prescription medication contains two active ingredients, amlodipine and valsartan, which work together to reduce the blood pressure and improve blood flow in all parts of the body. Amlodipine is known as a calcium blocker, which helps to relax the blood vessels and improve the flow of blood. While valsartan is an angiotensin receptor blocker, it helps to lower blood pressure by blocking the action of a hormone called angiotensin II. The medicine should be taken once a day at the same time, with food or without food.
