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 ...
Adrenergic means "working on adrenaline (epinephrine) or noradrenaline (norepinephrine)" [1] [2] (or on their receptors). When not further qualified, it is usually used in the sense of enhancing or mimicking the effects of epinephrine and norepinephrine in the body.
This is a list of adrenergic drugs. These are pharmaceutical drugs , naturally occurring compounds and other chemicals that influence the function of the neurotransmitter epinephrine (adrenaline). Receptor ligands
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.
Thujone (/ ˈ θ uː dʒ oʊ n / ⓘ [2]) is a ketone and a monoterpene that occurs predominantly in two diastereomeric forms: (−)-α-thujone and (+)-β-thujone. [3] [4]Though it is best known as a chemical compound in the spirit absinthe, it is only present in trace amounts and is unlikely to be responsible for the spirit's purported stimulant and psychoactive effects.
Alpha-adrenergic agonists are a class of sympathomimetic agents that selectively stimulates alpha adrenergic receptors. The alpha-adrenergic receptor has two subclasses α 1 and α 2. Alpha 2 receptors are associated with sympatholytic properties. Alpha-adrenergic agonists have the opposite function of alpha blockers.
The α 1-adrenergic receptor has several general functions in common with the α 2-adrenergic receptor, but also has specific effects of its own. α 1-receptors primarily mediate smooth muscle contraction, but have important functions elsewhere as well. [3]
Adrenergic blocking agents are a class of drugs that exhibit its pharmacological action through inhibiting the action of the sympathetic nervous system [1] in the body. The sympathetic nervous system(SNS) is an autonomic nervous system that we cannot control by will.
