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] In newborn babies it continues to be the preferred treatment for very low blood pressure. [5]
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.
Although it is important to know that there is a correlation between the two drugs, if l-DOPA doesn't work dopamine agonists are also ineffective. [1] The early dopamine agonists, such as bromocriptine, were ergot derived and activated the D 2-receptor. [7] They induced major side effects such as fibrosis of cardiac valves.
Dopaminergic medications that are used to treat Parkinson's disease are sometimes associated with the development of a dopamine dysregulation syndrome, which involves the overuse of dopaminergic medication and medication-induced compulsive engagement in natural rewards like gambling and sexual activity.
Other medications that convert into dopamine, as opposed to functioning as dopamine analogs, alleviate the effects of the degeneration of dopamine-producing neurons. One dopamine precursor, Levodopa, was the first drug approved specifically for Parkinson's disease. [2] DRT increases dopamine in the brain to optimal levels in order to return ...
A dopamine reuptake inhibitor (DRI) is a class of drug which acts as a reuptake inhibitor of the monoamine neurotransmitter dopamine by blocking the action of the dopamine transporter (DAT). Reuptake inhibition is achieved when extracellular dopamine not absorbed by the postsynaptic neuron is blocked from re-entering the presynaptic neuron.

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 have been used in treating schizophrenia , bipolar disorder , and stimulant psychosis . [ 1 ]
