2. -adrenergic agonist. Beta2-adrenergic agonists, also known as adrenergic β2 receptor agonists, are a class of drugs that act on the β 2 adrenergic receptor. Like other β adrenergic agonists, they cause smooth muscle relaxation. β 2 adrenergic agonists' effects on smooth muscle cause dilation of bronchial passages, vasodilation in muscle ...
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-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 ...
β 2 -adrenoceptor agonists are a group of drugs that act selectively on β 2 -receptors in the lungs causing bronchodilation. β 2 -agonists are used to treat asthma and COPD, diseases that cause obstruction in the airways. Prior to their discovery, the non-selective beta-agonist isoprenaline was used. The aim of the drug development through ...
Beta blocker. Skeletal formula of propranolol, the first clinically successful beta blocker. 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 ).

Universal Audio is an American company that designs, imports, and markets audio signal processing hardware and effect pedals, audio interfaces, digital signal processing, virtual instrument, and digital audio workstation software and plug-ins . Founded in 1958 by Bill Putnam, Sr. with products produced under the Universal Audio brand through ...
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 ...
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.
