A catecholamine (/ ˌ k æ t ə ˈ k oʊ l ə m iː n /; abbreviated CA) is a monoamine neurotransmitter, an organic compound that has a catechol (benzene with two hydroxyl side groups next to each other) and a side-chain amine. [1] Catechol can be either a free molecule or a substituent of a larger molecule, where it represents a 1,2 ...
Catecholaminergic means "related to catecholamines". The catecholamine neurotransmitters include dopamine , epinephrine (adrenaline), and norepinephrine (noradrenaline). A catecholaminergic agent (or drug ) is a chemical which functions to directly modulate the catecholamine systems in the body or brain.
Monoamine neurotransmitters are neurotransmitters and neuromodulators that contain one amino group connected to an aromatic ring by a two-carbon chain (such as -CH 2-CH 2-). Examples are dopamine , norepinephrine and serotonin .

These are drugs whose primary effects are thought to be mediated by different neurotransmitter systems (dopamine for stimulants, serotonin for antidepressants), but many also increase levels of norepinephrine in the brain. [53] Amphetamine, for example, is a stimulant that increases release of norepinephrine as well as dopamine. [54]
l-DOPA can be manufactured and in its pure form is sold as a drug with the INN Tooltip International Nonproprietary Name levodopa. Trade names include Sinemet, Pharmacopa, Atamet, and Stalevo. As a drug, it is used in the clinical treatment of Parkinson's disease and dopamine-responsive dystonia. l-DOPA has a counterpart with opposite chirality ...
Nicotinic receptors cause the release of catecholamine from the adrenal medulla, and also site specific excitation or inhibition in brain. Both Nm and Nn receptor types are non-selective cation channels, permeable to sodium and potassium ions, in addition to that, Nn type receptors allow for calcium ion flow.
Catecholaminergic cell groups refers to collections of neurons in the central nervous system that have been demonstrated by histochemical fluorescence to contain one of the neurotransmitters dopamine or norepinephrine. Thus, it represents the combination of dopaminergic cell groups and noradrenergic cell groups. [1]
