Corabrad 5 mg Tablet is used to treat symptomatic stable angina pectoris and chronic heart failure. It contains Ivabradine, which works by reducing the heart rate by a few beats per minute. In this way, it lowers the heart's requirement for oxygen, especially in situations where an angina attack can happen. This helps control or reduce the chances of more angina attacks. It may cause side effects such as feeling tired, irregular or rapid feeling heartbeat, headache, dizziness, visual impairment or blurry vision. Before taking this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions.
