What Is a Beta Blocker? 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 Beta Blockers Beta blockers are medicines used for high blood pressure, heart problems and glaucoma. Patients receiving allergen immunotherapy (allergy shots) should not be on beta blockers because they function by blocking the effects of epinephrine, which is the treatment for a serious allergic reaction.

- Beta Blockers. This includes a group of drugs usually ending in “-ol”, such as atenolol, metoprolol, nebivolol, carvedilol, and bisoprolol. This group of drugs acts primarily by reducing heart rate and the strength of heart contraction. The major use of these drugs was in treating hypertension (previously)and angina.

List of Beta Blockers Sotalol (Betapace®, Sorine®) is unique among beta blockers in that it also blocks potassium channels in the heart. Beta blockers that have not been approved (or are unavailable) in the United States are not included in these lists.

Beta-Blockers for Heart Failure How It Works. Beta-blockers are a class of drugs used to control symptoms of heart failure that are made worse by certain hormones called catecholamines. The body releases these hormones as part of its response to heart failure. For this and other reasons, beta-blockers have been shown to be effective for treating most people who have heart failure.

Among Taking Aspirin, Beta Blockers, Cholesterol-Lowering 'Statin' Drug Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure. Beta blockers work by blocking the effects of the hormone epinephrine, also known as adrenaline. When you take beta blockers, your heart beats more slowly and with less force, thereby reducing blood pressure. Beta blockers also help blood vessels open up to improve blood flow.

- They block sympathetic stimulation of the heart and reduce systolic pressure, heart rate, cardiac contractility and output, so decrease myocardial oxygen demand and increase exercise tolerance. Beta adrenergic blocking agents are used to treat angina, control abnormal heart rhythms and to reduce high blood pressure. However, blocking of the beta receptors may cause bronchial constriction therefore care has to be taken with the use of beta blockers in patients with respiratory conditions. Please refer to the drug classes listed below for further information.

Drug cabinet: Beta blockers Control of blood pressure. Beta blockers are commonly used to help lower blood pressure, usually as a part of a treatment plan that may include an ACE inhibitor (for example, ramipril) and/or a calcium channel blocker (for example, amlodipine).Read more about calcium channel blockers.eta blockers are classified as being non-selective and selective. Non-selective beta blockers, such as propranolol, are active in blocking adrenaline and noradrenaline in other areas of the body, as well as the heart.

- Uses. Beta blockers are widely known as beta-adrenergic blocking agents, these block adrenaline from binding to the beta receptors on the nerves. Beta blockers are used primarily in the treatment of cardiac arrhythmia and high blood pressure.eta Receptors. To best explain what a beta blocker does, you need to understand a little bit about the nervous system and what beta receptors are. A beta receptor is a protein molecule that processes specific messages carried by the central nervous system and various hormones.

5 Lifestyle Changes Could Prevent 80 Percent of Heart Attacks Beta-blockers are drugs commonly used in the treatment of high blood pressure and congestive heart failure. They work primarily by blocking the neurotransmitters norepinephrine and epinephrine (adrenaline) from binding to beta receptors, thereby dilating blood vessels, which reduces your heart rate and blood pressure.

Beta-blockers - blood pressure medication Beta-blockers lower your blood pressure by blocking the effect of hormones called adrenaline and ­noradrenaline. By blocking these hormones, beta-blockers slow down your heart rate and reduce the force at which blood is pumped round your body. Beta-blockers also block your kidneys from ­producing a hormone called angiotensin II. Reducing the amount of angiotensin in your body allows your blood vessels to relax and widen, making it easier for blood to flow through. Beta-blockers are not usually used as a first choice medicine for high blood pressure.

Newport Beach Neurologists Beta Blockers in the Treatment of Migraine. Of all the preventative medicines available across the United States, the drugs known as beta blockers are probably the most frequently prescribed. The beta refers to receptors on the blood vessels known as beta receptors. Beta blockers prevent the chemical interaction of certain chemicals with this receptor, hence, the term beta blockers..

Resurrection Plant Font Size. A. A. A. Beta-blockers are drugs used to treat high blood pressure. They block the effects of the sympathetic nervous system on the heart. This reduces the work of the heart so that it requires less blood and oxygen. As a result, the heart doesn't have to work as hard, which in turn lowers blood pressure.
