Concor COR 1.25 Tablet is used to manage high blood pressure and chest pain due to angina. It works by slowing the heart rate, reducing strain on the heart, and making it easier for blood to circulate. This helps control hypertension, improves heart function, and lowers the risk of future cardiovascular complications.

In addition to managing hypertension, this tablet can also be used in conjunction with other medications for the management of angina pectoris (chest pain) and as an add-on therapy for stable chronic heart failure. By lowering blood pressure and slowing the heart rate, it aids in preventing heart attacks, strokes, and kidney problems.

It's important to take this medicine orally as directed by your doctor. Let your doctor know about any pre-existing conditions or ongoing medications before starting this medicine. If you notice any side effects while on this medicine, inform your doctor immediately. Continue taking the tablet for the duration prescribed by your doctor for optimal results.
