Bisoprolol fumarate is a medication used to treat high blood pressure, heart failure, and angina (chest pain). It belongs to the class of drugs called beta-blockers, which work by blocking the action of certain natural chemicals in the body such as adrenaline. This causes the heart to beat slower and with less force, reducing blood pressure and the workload on the heart. Bisoprolol fumarate is usually taken orally as a tablet, and is available in various strengths. It is important to follow the instructions of a healthcare professional when taking this medication.
