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.
Amphetamine's Effects on the Brain. When amphetamines are used, the neurotransmitters dopamine and norepinephrine are released from nerve endings in the brain and their reuptake is inhibited. This a buildup of these neurotransmitters at synapses in the brain.5 When mixed with alcohol or other drugs, the effects of prescription amphetamines are enhanced. 16 The onset of effects from injecting methamphetamines occurs immediately. When this drug is snorted, effects occur within 3 to 5 minutes; when ingested orally, effects occur within 15 to 20 minutes.
