The drug that relaxes blood vessels and slows the heart rate to improve blood flow and decrease blood pressure is Metoprolol (Toprol). Metoprolol belongs to a class of drugs called beta blockers, which work by blocking the action of certain natural chemicals in the body, such as adrenaline. This helps to reduce the workload on the heart and widens the blood vessels, allowing blood to flow more easily.
