Toxicity of beta-1 blocker will contribute to symptoms including bradycardia, hypotension, due to its extensive blockage of beta-1 receptor. [5] Moreover, overdose of beta-1 blocker may lead to the loss of their selectivity and bind to beta-2 receptor, causing bronchopulmonary symptoms. [5]
While some studies suggest that there are minimal differences in side effects between asthma patients and non-asthma patients, beta 1 blockers are generally avoided in patients with asthma or chronic obstructive pulmonary disease due to their potential to block beta 2 receptors, particularly at high doses.

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) antagonists and alpha-2 (α 2) agonists, which are used to treat high ...
Some beta blockers block activation of all types of β-adrenergic receptors and others are selective for one of the three known types of beta receptors, designated β 1, β 2 and β 3 receptors. [3]: 153 β 1-adrenergic receptors are located mainly in the heart and in the kidneys. [4] β 2-adrenergic receptors are located mainly in the lungs ...
The beta-2 adrenergic receptor (β 2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that binds epinephrine (adrenaline), a hormone and neurotransmitter whose signaling, via adenylate cyclase stimulation through trimeric G s proteins, increases cAMP, and, via downstream L-type calcium channel interaction, mediates physiologic responses such as smooth ...
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]
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. In addition to cardiac tissue, beta ...
β 1-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 .
