Dopamine receptors are a class of G protein-coupled receptors that are prominent in the vertebrate central nervous system (CNS) and are implicated in many neurological processes, including motivational and incentive salience, cognition, memory, learning, and fine motor control, as well as modulation of neuroendocrine signaling.
The side effects are predominantly collected from studies of Parkinson's disease, where dopamine agonists are commonly used as a first-line treatment with levodopa. [16] Dopamine agonists are divided into two subgroups or drug classes, first-generation and newer agents.
Administration can prevent common side-effects, such as nausea and vomiting, as a result of interaction with D 2 receptors in the vomiting center (or cheomoreceptor trigger zone) located outside the blood–brain barrier. [2] Examples of extracerebral decarboxylase inhibitors include carbidopa and benserazide.
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.

[5] [6] However, non-selective DRAs, including norepinephrine–dopamine releasing agents (NDRAs) like amphetamine and methamphetamine, serotonin–norepinephrine–dopamine releasing agents (SNDRAs) like MDMA and mephedrone, and serotonin–dopamine releasing agents (SDRAs) like 5-chloro-αMT are known. [7] [8] [9]
Side effects of levodopa include nausea, the wearing-off phenomenon, dopamine dysregulation syndrome, and levodopa-induced dyskinesia, among others. [3] The drug is a centrally permeable monoamine precursor and prodrug of dopamine and hence acts as a dopamine receptor agonist. [3] Chemically, levodopa is an amino acid, a phenethylamine, and a ...
This in turn leads to increased extracellular concentrations of both norepinephrine and dopamine and, therefore, an increase in adrenergic and dopaminergic neurotransmission. [1] A closely related type of drug is a norepinephrine–dopamine releasing agent (NDRA).
