A dopamine antagonist, also known as an anti-dopaminergic and a dopamine receptor antagonist (DRA), is a type of drug which blocks dopamine receptors by receptor antagonism. Most antipsychotics are dopamine antagonists, and as such they have found use in treating schizophrenia , bipolar disorder , and stimulant psychosis . [ 1 ]
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.

[3] [4] Use in pregnancy and breastfeeding is of unclear safety. [5] It is a dopamine agonist and works by triggering dopamine D 2 receptors. [4]
This is a list of dopaminergic drugs. These are pharmaceutical drugs , naturally occurring compounds and other chemicals that influence the function of the neurotransmitter dopamine . Dopamine receptor ligands
[22] [21] Janssen pharmacologists discovered that some antipsychotic drugs had a significant effect on dopamine receptors in the central chemoreceptor trigger zone that regulated vomiting, and started searching for a dopamine antagonist that would not pass the blood–brain barrier, thereby being free of the extrapyramidal side effects that ...
Dopamine, sold under the brand name Intropin among others, is a medication most commonly used in the treatment of very low blood pressure, a slow heart rate that is causing symptoms, and, if epinephrine is not available, cardiac arrest. [4]
