Beta blockers are used to lower blood pressure and slow the heart. The following drugs are on a common list of beta blockers.: According to the American Heart Association (AHA), commonly prescribed beta blockers include: -Acebutolol (Sectral) -Atenolol (Tenormin) -Betaxolol (Kerlone)
Beta-blockers are drugs that bind to beta-adrenoceptors and thereby block the binding of norepinephrine and epinephrine to these receptors. This inhibits normal sympathetic effects that act through these receptors. Therefore, beta-blockers are sympatholytic drugs. Some beta-blockers, when they bind to the beta-adrenoceptor, partially activate the receptor while preventing norepinephrine from binding to the receptor. These partial agonists therefore provide some background of sympathetic activity while preventing normal and enhanced sympathetic activity.
