Alpha-adrenergic agonist. 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.
Clonidine. Clonidine, sold under the brand name Catapres among others, is an α 2A -adrenergic agonist [10] medication used to treat high blood pressure, ADHD, drug withdrawal ( alcohol, opioids, or nicotine ), menopausal flushing, diarrhea, spasticity, and certain pain conditions. [11]
The alpha-2 ( α2) adrenergic receptor (or adrenoceptor) is a G protein-coupled receptor (GPCR) associated with the G i heterotrimeric G-protein. It consists of three highly homologous subtypes, including α 2A -, α 2B -, and α 2C -adrenergic. Some species other than humans express a fourth α 2D -adrenergic receptor as well. [1]
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) agonists and alpha-2 (α 2) agonists, which are used to treat high blood ...
Adrenergic agonist. 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.
Xylazine is a potent α 2 adrenergic agonist. [23] [3] When xylazine and other alpha-2 adrenergic receptor agonists are administered, they distribute throughout the body within 30–40 minutes. [17] Due to xylazine's highly lipophilic nature, it directly stimulates central α 2 receptors as well as peripheral α-adrenoceptors in a variety of ...
Tizanidine, sold under the brand name Zanaflex among others, is an alpha-2 (α 2) adrenergic receptor agonist, [2] similar to clonidine, that is used to treat muscle spasticity due to spinal cord injury, multiple sclerosis, and spastic cerebral palsy. [3] Effectiveness appears similar to baclofen or diazepam. [4]
Brimonidine is an α 2 agonist medication used to treat open-angle glaucoma, ocular hypertension, and rosacea. [1] [2] In rosacea it improves the redness. [2] It is used as eye drops or applied to the skin. [1] [2] Common side effects when used in the eyes include itchiness, redness, and a dry mouth. [1] Common side effects when used on the ...
