A medication called Telgard M 25 Tablet ER is used to treat high blood pressure. When the blood arteries supplying your heart with blood narrow, you get hypertension, or elevated blood pressure. As a result, the heart cannot pump blood to other areas of the body efficiently, blood cannot flow easily to the heart, and the heart rate rises. A heart attack or even chest pain may result from the strain this places on the heart. Telgard M 25 Tablet ER lowers blood vessel pressure. It facilitates easier blood flow to your heart by relaxing the blood arteries. This lowers cardiac strain and lowers heart rate.
