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.

- 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.

beta-blocker medical Definition of beta-blocker : any of a group of drugs (as propranolol) that combine with and block the activity of a beta-receptor to decrease the heart rate and force of contractions and lower high blood pressure and that are used especially to treat hypertension, angina pectoris, and ventricular and supraventricular arrhythmias — compare alpha-blocker

Beta blocker Beta blockers block the action of endogenous catecholamines epinephrine (adrenaline) and norepinephrine (noradrenaline) -in particular on adrenergic beta receptors, of the sympathetic nervous system, which mediates the fight-or-flight response.1-adrenergic receptors are located mainly in the heart and in the kidneys. β2-adrenergic receptors are located mainly in the lungs, gastrointestinal tract, liver, uterus, vascular smooth muscle, and skeletal muscle. β3-adrenergic receptors are located in fat cells.

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.

- Beta-blockers can also block the stimulation of the heart form electrical impulses-they can control irregular heartbeats-thus lowering the activity of the heart and slowing down the heart rate. Hypertension-beta-blockers lower blood pressure by slowing down the heart rate, as well as reducing the force of the heart. Blood still gets to all parts of the body, but at reduced pressure. Glaucoma-pressure within the eyeball is reduced with beta-blocker eye drops.

Beta-blockers Because of their effect on the heart cells, beta-blockers may be used to: 1  Prevent angina pains. 2  Reduce the risk of a further heart attack (myocardial infarction) if you have already had one. 3  Control certain abnormal heart rhythms (arrhythmias). 4  Help to treat heart failure. 5  Lower your blood pressure if it is too high.

- Calcium channel blockers are also called calcium antagonists or calcium blockers. They disrupt the calcium ion conduction of calcium channels. Calcium channel blockers helps to decrease the heart rate, which can further lower the blood pressure, relieve the chest pain and control an irregular beat. They are majorly used to treat Angina Pectoris and Hypertension, they are also employed in Cardiac Arrhythmias. CLASSIFICATION:1. MECHANISM OF ACTION:1.

Why Do Antihypertensives Cause Cough? Beta-blockers are used for their antagonistic effect on cardiac beta-1 adrenoceptors. Two types of beta-blockers are available: beta-1 selective adrenoceptor antagonists (eg, metoprolol, atenolol) and nonselective beta-1/ beta-2 adrenoceptor antagonists (eg, carvedilol, propranolol, sotalol, timolol).

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. If you require the regular use of a beta blocker, you should not take allergy shots. Below is a partial list of the currently available beta blocker medications. Ask your pharmacist, prescribing physician or one of our nurses if you are not sure if your medication is a beta blocker.

How do beta blockers reduce the heart rate? Answers. Best Answer: Beta blockers are medicines that affect the body's response to certain nerve impulses. This, in turn, decreases the force and rate of the heart's contractions, which lowers blood pressure and reduces the heart's demand for oxygen.
