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 ]
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
The most commonly prescribed class of antidepressants in the USA today are the selective serotonin reuptake inhibitors (SSRIs). These drugs inhibit the uptake of the neurotransmitter 5-HT by blocking the SERT, thus increasing its synaptic concentration, and have shown to be efficacious in the treatment of depression, however sexual dysfunction ...
Relative to serotonin–norepinephrine–dopamine reuptake inhibitors (SNDRIs), which also inhibit the reuptake of norepinephrine in addition to serotonin and dopamine, SDRIs might be expected to have a reduced incidence of certain side effects, namely insomnia, appetite loss, anxiety, and heart rate and blood pressure changes.

A norepinephrine–dopamine reuptake inhibitor (NDRI) is a type of drug that inhibits the reuptake of the monoamine neurotransmitters norepinephrine and dopamine and thereby increases extracellular levels of these neurotransmitters and noradrenergic and dopaminergic neurotransmission. [1]
Rare but serious side effects include seizures, [10] [11] liver toxicity, [24] psychosis, [25] and risk of overdose. [26] Bupropion use during pregnancy may be associated with increased likelihood of congenital heart defects. [27] Bupropion acts as a norepinephrine–dopamine reuptake inhibitor (NDRI) and a nicotinic receptor antagonist. [2]
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.
