Beta-1 adrenergic receptor. The beta-1 adrenergic receptor (β 1 adrenoceptor), also known as ADRB1, can refer to either the protein-encoding gene (gene ADRB1) or one of the four adrenergic receptors. [5] It is a G-protein coupled receptor associated with the Gs heterotrimeric G-protein that is expressed predominantly in cardiac tissue.
The membrane the receptor is bound to in cells is shown with a gray stripe. The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like beta blockers, beta-2 (β 2 ...
Beta-blockade of the β 1 receptor will inhibit cAMP from phosphorylating, and it will decrease the ionotrophic and chronotropic effect. Note that drugs may be cardioselective, or act on β 1 receptors in the heart only, but still have instrinsic sympathomimetic activity. Acebutolol (has intrinsic sympathomimetic activity, ISA) [80] Atenolol [80]

1. -adrenergic agonist. β1-Adrenergic receptor agonists, also known as beta-1 agonists, are a class of drugs that bind selectively to the β 1 -adrenergic receptor. As a result, they act more selectively upon the heart. β-Adrenoceptors typically bind to norepinephrine release by sympathetic adrenergic nerves and to circulating epinephrine.
Beta-adrenergic agonist. Beta adrenergic agonists or beta agonists are medications that relax muscles of the airways, causing widening of the airways and resulting in easier breathing. [1] They are a class of sympathomimetic agents, each acting upon the beta adrenoceptors. [2] In general, pure beta-adrenergic agonists have the opposite function ...
Bisoprolol. Bisoprolol, sold under the brand name Zebeta among others, is a beta blocker which is selective for the beta-1 receptor [7] and used for cardiovascular diseases, [7] including tachyarrhythmias, high blood pressure, angina, and heart failure. [7][8] It is taken by mouth. [7]
