Beta 1-adrenergic agonists, also known as Beta 1-adrenergic receptor agonists, are a class of drugs that bind selectively to the beta-1 adrenergic receptor. As a result, they act more selectively upon the heart. Beta-adrenoceptors typically bind to norepinephrine release by sympathetic adrenergic nerves and to circulating epinephrine.
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.
β 1 agonists stimulate adenylyl cyclase activity and opening of calcium channel (cardiac stimulants; used to treat cardiogenic shock, acute heart failure, bradyarrhythmias). Selected examples are: Denopamine; Dobutamine; Dopexamine (β 1 and β 2) Epinephrine (non-selective) Isoprenaline , isoproterenol (β 1 and β 2) Prenalterol; Xamoterol
Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms ( arrhythmia ), and to protect the heart from a second heart attack after a first heart attack ( secondary prevention ). [1]
Bisoprolol, sold under the brand name Zebeta among others, is a beta blocker which is selective for the beta-1 receptor and used for cardiovascular diseases, including tachyarrhythmias, high blood pressure, angina, and heart failure. It is taken by mouth.

It primarily works by direct stimulation of β 1 receptors, which increases the strength of the heart's contractions, leading to a positive inotropic effect. Generally it has little effect on a person's heart rate. Dobutamine was approved for medical use in the United States in 1978.
Metoprolol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a selective antagonist of the β 1-adrenergic receptor and has no intrinsic sympathomimetic activity. Metoprolol exerts its effects by blocking the action of certain neurotransmitters, specifically adrenaline and noradrenaline.
An adrenergic agonist is a drug that stimulates a response from the adrenergic receptors. The five main categories of adrenergic receptors are: α 1, α 2, β 1, β 2, and β 3, although there are more subtypes, and agonists vary in specificity between these receptors, and may be classified respectively. However, there are also other mechanisms ...
Betaxolol is a selective beta 1 receptor blocker used in the treatment of hypertension and angina. It is also a adrenergic blocker with no partial agonist action and minimal membrane stabilizing activity.
Beta 1 blockers. Beta 1 blockers bind to the beta 1 receptor without activating it, inhibiting the receptor-mediated effects. The beta-1 receptor is a G-protein-coupled receptor with the Gs alpha subunit as its main signaling protein.
