A Beta blocker is a prescription drug used to lower blood pressure and reduce heart rate. It counteracts the effects of adrenaline to beta receptors, which are located throughout the body including the nervous system and heart.Beta blockers relax the heart and allow it to beat slower, which reduces blood pressure.eta blockers are used for treating high blood pressure, heart failure, glaucoma, hyperthyroidism, chest pain (angina), migraine headaches, heart attacks, irregular heart rhythm (arrhythmia), certain types of tremors and generalized anxiety disorder.
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.
