Uses for Byvalson
Nebivolol and valsartan combination is 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 stroke, heart failure, or kidney failure. Lowering blood pressure will reduce the risk of strokes and heart attacks.
Nebivolol is a beta-blocker. It works by affecting the response to nerve impulses in certain parts of the body, like the heart. As a result, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of blood and oxygen is increased to the heart.
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.
This medicine is available only with your doctor's prescription.
