Uses For Twynsta
Telmisartan and amlodipine is a combination of medicines that may be used alone or with other medicines 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 can reduce the risk of strokes and heart attacks.
Telmisartan 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, the blood vessels relax and this decreases blood pressure. When blood pressure is lowered, the amount of blood and oxygen that go to the heart is increased.
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.
This medicine is available only with your doctor's prescription.
