By inhibiting the dopamine transporter, a dopamine reuptake inhibitor increases the body's extracellular concentrations of dopamine, which in turn increases dopaminergic neurotransmission and creates feelings of pleasure or even euphoria. A dopamine reuptake inhibitor has a number of medical applications.
HOW DRUGS AFFECT NEUROTRANSMITTERS. Dopamine appeared very early in the course of evolution and is involved in many functions that are essential for survival of the organism, such as motricity, attentiveness, motivation, learning, and memorization.ut not all drugs increase dopamine levels in the brain in the same way. 1  Some substances imitate natural neuromediators and take their place on their receptors. 2  Other substances increase the secretion of natural neuromediators. 3  Still other substances block a natural neuromediator.
