Barilol 5mg Tablets are a medication used for the treatment of high blood pressure (hypertension). The active ingredient in Barilol is bisoprolol fumarate, which is a beta-blocker. Bisoprolol works by blocking the effects of the hormone adrenaline, which can increase heart rate and blood pressure. This helps to reduce the workload on the heart and improve blood flow, which can help to lower blood pressure. Barilol is typically taken once a day and should be taken regularly for best results. As with all medications, it is important to follow the instructions of your doctor or pharmacist and to report any side effects or concerns you may have.
