Adrenergic agonist - Wikipedia
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. However, there are also other mechanisms ...

Adrenergic agonists are drugs that work by mimicking the functioning of the sympathetic nervous system—the part of the nervous system that increases heart rate, blood pressure, breathing rate, and eye pupil size.

Drugs that bind to and activate adrenergic receptors. A medication used to treat symptomatic neurogenic orthostatic hypotension (nOH) caused by dopamine beta-hydroxylase deficiency, non-diabetic autonomic neuropathy and primary autonomic failure caused by conditions such as Parkinson's disease.
Adrenergic receptor - Wikipedia
Adrenaline or noradrenaline are receptor ligands to either α 1, α 2 or β-adrenoreceptors. The α 1 couples to G q, which results in increased intracellular Ca 2+ and subsequent smooth muscle contraction.
Alpha-2 Adrenergic Receptor Agonists: A Review of Current ...
Guanabenz, guanfacine, clonidine, tizanidine, medetomidine, and dexmedetomidine are all α-2 agonists that vary in their potency and affinities for the various α-2 receptor subtypes. Clonidine, tizanidine, and dexmedetomidine have received the greatest clinical use and will be addressed more thoroughly. Summary data are provided in Table 2. Table 2.
