Beta-adrenoceptor blocking drugs (beta-blockers) block the beta-adrenoceptors in the heart, peripheral vasculature, bronchi, pancreas, and liver. Many beta-blockers are available but experience in children is limited to the use of only a few. . beta-adrenoceptor: One of the many the receptor sites at which noradrenaline and other hormones act to cause muscle to contract or relax. Beta-adrenoceptors occur in blood vessels, in the heart, in the bronchi, in the intestines, in the bladder, in the womb and elsewhere. The effect of the hormones at these sites can be prevented by.

Beta-adrenoceptor blocking agents, or beta-blockers as they are more commonly called, are used predominantly in the treatment of such conditions as hypertension, angina and cardiac arrhythmias.

They work by preventing catecholamines from accessing the beta-adrenergic receptor sites in the heart, bronchi and other organs (Hopkins, ). beta-adrenergic blocking agent (beta-blocker) any of a group of drugs that block the action of epinephrine at beta-adrenergic receptors on cells of effector organs.

Anthony C. Hackney, in Doping, Performance Enhancing Drugs, and Hormones in Sport, Beta blockers—beta-adrenergic receptor blockers—are used primarily to treat heart disease and related conditions. These drugs reduce blood pressure and manage cardiac arrhythmias and are cardioprotective after myocardial infarction (heart attack).

Many beta-blockers are now available and in general they are all equally effective. There are, however, differences between them, which may affect choice in treating particular diseases or individual.

Beta adrenergic blocking agents: A class of drugs, also called beta blockers, that block beta-adrenergic substances such as adrenaline (epinephrine), a key agent in the "sympathetic" portion of the autonomic (involuntary) nervous system. By blocking the action of the sympathetic nervous system on the heart, these agents relieve stress on the heart.

They slow the heart beat. Alpha- and beta-adrenoceptor-blocking agents are divided into primary subgroups on the basis of their receptor selectivity. All of these agents are pharmacologic antagonists or partial agonists and most are reversible and competitive in action.

Beta-adrenergic blocking agents for the eye are used to treat certain types of glaucoma. They appear to work by reducing the production of fluid in the eye. This lowers the pressure in the eye.

The availability of beta-adrenoceptor blocking agents has been recognized as a major therapeutic advance of this century.

Nadolol () Definition (NCI) A non-selective beta-adrenergic antagonist with antihypertensive and antiarrhythmic activities.

Nadolol competitively blocks beta-1 adrenergic receptors located in the heart and vascular smooth muscle, inhibiting the activities of the catecholamines epinephrine and norepinephrine and producing negative inotropic and chronotropic effects. beta-blocker or beta-adrenergic blocking agent (bā`tə ăd'rənûr`jĭk), drug that reduces the symptoms connected with hypertension hypertension or high blood pressure, elevated blood pressure resulting from an increase in the amount of blood pumped by the heart or from increased resistance to the flow of blood through the small arterial blood vessels (arterioles).

Beta blockers, also known as beta-adrenergic blocking agents, are a class of drugs that works by blocking the neurotransmitters norepinephrine and epinephrine from binding to receptors.

There are three known types of beta receptors, known as beta 1 (β 1), beta 2 (β 2) and beta 3 (β 3). β 1 -adrenergic receptors are located commonly in the.

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.

Beta blockers cause your heart to beat more slowly and with less force, which lowers blood pressure.

Beta blockers are a group of drugs that inhibit the sympathetic activation of β-adrenergic receptors. Cardioselective blockers (e.g., atenolol, bisoprolol) primarily block β 1 receptors in the heart, causing decreased heart rate, cardiac contractility, cardiac workload, and AVN conduction.
