Bisoprolol is a prescription cardiovascular medication belonging to the beta‑blocker class. It works by blocking beta‑1 adrenergic receptors in the heart, which slows the heart rate and reduces blood pressure, making it easier for the heart to pump and helping to lower the workload on the cardiovascular system. 
It is commonly used to treat high blood pressure (hypertension) and angina (chest pain), and in some cases heart failure.
