What is an alpha-blocker? A Brigham and Women's Hospital answered. Alpha blockers are very potent medications often used for people whose blood pressure doesn't respond to less strong drugs. Most people who have high blood pressure aren't controlled with one medicine. Usually it takes two medicines to control it. But alpha blockers are sort of the bigger guns.

- 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.

Beta blocker The mixed alpha-and beta blocker labetalol is especially useful for treatment of concomitant tachycardia and hypertension induced by methamphetamine. The phenomenon of unopposed alpha stimulation has not been reported with the use of beta blockers for treatment of methamphetamine toxicity.

Beta Blockers (Drug Class, List of Brand and Generic Names) What are beta blockers and how do they work? Beta blockers, also known as beta-adrenergic blocking agents, are drugs that block norepinephrine and epinephrine (adrenaline) from binding to beta receptors on nerves. Norephinephrine and epinephrine are produced by nerves throughout the body as well as by the adrenal gland.

Heart Disease and Beta-Blocker Therapy Beta-blockers are one of the most widely prescribed classes of drugs to treat hypertension (high blood pressure) and are a mainstay treatment of congestive heart failure. Beta-blockers work by blocking the effects of epinephrine (adrenaline) and slowing the heart's rate, thereby decreasing the heart’s demand for oxygen. Long-term use of beta-blockers helps manage chronic heart failure. Examples of beta-blockers include:

Beta blockers By Mayo Clinic Staff. 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.

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.

Beta-Adrenoceptor Antagonists (Beta-Blockers) General Pharmacology. 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.

Beta-Adrenoceptor Antagonists (Beta-Blockers) The first generation of beta-blockers were non-selective, meaning that they blocked both beta-1 (β1) and beta-1 (β2) adrenoceptors. Second generation beta-blockers are more cardioselective in that they are relatively selective for β1 adrenoceptors. Note that this relative selectivity can be lost at higher drug doses.

Betablockers A beta blocker is often used to treat high blood pressure or an irregular heart beat. This medicine can also be used to treat congestive heart failure, but people with severe heart failure may not be able to take a beta blocker. A beta blocker reduces the risk of another heart attack for people who have already had one.

Beta blocker Beta blockers block the action of endogenous catecholamines epinephrine (adrenaline) and norepinephrine (noradrenaline) on adrenergic beta receptors, of the sympathetic nervous system, which mediates the fight-or-flight response.eta receptors are found on cells of the heart muscles, smooth muscles, airways, arteries, kidneys, and other tissues that are part of the sympathetic nervous system and lead to stress responses, especially when they are stimulated by epinephrine (adrenaline).

- 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.
