US Brand Names
Amlodipine and valsartan is a combination of medicines that are used to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a heart failure or kidney failure. Lowering blood pressure reduces the risk of strokes and heart attacks.
Amlodipine is a calcium channel blocker (CCB). It affects the movement of calcium into the cells of the heart and blood vessels. As a result, amlodipine relaxes the blood vessels and increases the supply of blood and oxygen to the heart while reducing its workload.
Valsartan is an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes blood vessels to tighten. As a result, valsartan relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.
