Bisoprolol is a drug belonging to the group of beta blockers, a class of medicines used primarily in cardiovascular diseases. More specifically, it is a selective type β1 adrenergic receptor blocker. The U.S. Food and Drug Administration (FDA) approved an application by Duramed Pharmaceutical for Zebeta Oral Tablets (Bisoprolol Fumarate) as a new molecular entity on July 31, 1992.[3] It has since been approved by the FDA for manufacture by Teva, Mylan, Sandoz, Aurobino, and Unichem.[4]
