Cardipin is used alone or together with other medicines to treat angina (chest pain) and 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. High blood pressure may also increase the risk of heart attacks. These problems may be less likely to occur if blood pressure is controlled. Cardipin is a calcium channel blocker. It affects the movement of calcium into the cells of the heart and blood vessels. As a result Cardipin relaxes blood vessels and increases the supply of blood and oxygen to the heart while reducing its workload.
