Anti-adrenaline: A beta blocker is a medication which prevents adrenaline-like compounds from connecting to the "beta adrenergic receptors" in the body. Beta-1 receptors affect heart squeeze, relaxation and rhythm and are usually the primary target. Medicines like metoprolol and atenolol work only on this receptor. Other "nonselective" beta blockers block beta-1 and beta-2, with or without other effects as well.
