Adrenergic transporter (norepinephrine transporter), a protein transporting norepinephrine from the synaptic cleft into nerve cells; Regarding pharmaceutical drugs: Adrenergic receptor agonist, a type of drug activating one or more subtypes of adrenergic receptors This includes drugs regulating blood pressure and antiasthmatic drugs.
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 ...
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.
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 mechanisms of sympathomimetic drugs can be direct-acting (direct interaction between drug and receptor), such as α-adrenergic agonists, β-adrenergic agonists, and dopaminergic agonists; or indirect-acting (interaction not between drug and receptor), such as MAOIs, COMT inhibitors, release stimulants, and reuptake inhibitors that increase the levels of endogenous catecholamines.
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]
