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.
[4] [19] [13] [12] Dopamine releasing agents like dextroamphetamine are able to rapidly increase striatal dopamine levels by 700 to 1,500% of baseline in rodents. [62] These drugs show greater magnitudes of impact on dopamine levels than do dopamine reuptake inhibitors like methylphenidate.
Conversely, these levels are decreased and the rewarding properties of BSR are blocked following administration of drugs that antagonize dopamine receptors or reduce the amount of extracellular dopamine, by promoting either degradation or re-uptake of the neurotransmitter. While dopamine is generally considered to be the main neurotransmitter ...
