Bystolic is made by Forest Pharmaceuticals, Inc.
Bystolic belongs to a group of drugs called beta-adrenergic blocking agents, more often known as
beta blockers. As the name implies, these medications block beta receptors in the body. Beta receptors are located in a number of places within the body, including the heart and blood vessels. Stress hormones (such as adrenaline) bind to these receptors and cause certain reactions in the body, such as:
At lower doses in most people, Bystolic helps to block a specific type of beta receptor called beta-1 receptors (at higher doses, it also blocks beta-2 receptors). By blocking beta-1 receptors, Bystolic causes the reverse effect of stress hormones. It decreases heart rate and both
systolic and diastolic blood pressure.
