A dopamine reuptake inhibitor (DRI) is a type 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. This, in turn, leads to increased extracellular concentrations of dopamine and therefore an increase in dopaminergic neurotransmission.
