Which drug remains a CNS stimulant that blocks dopamine reuptake in the brain?

Blocking the dopamine transporter (DAT) increases dopamine in the synaptic cleft, producing strong CNS stimulant effects. Cocaine is defined by its high affinity for DAT, effectively preventing dopamine reuptake and rapidly boosting dopamine signaling in the brain. This rapid reuptake blockade underlies its potent stimulant and reinforcing properties, along with sympathetic activation from increased norepinephrine and serotonin as well. Amphetamine also enhances dopaminergic signaling, but its primary action is to increase dopamine release and reverse transport through DAT rather than blocking reuptake as the main mechanism. Ketamine and PCP are dissociative drugs that act mainly as NMDA receptor antagonists and do not function primarily as dopamine reuptake inhibitors. So, the drug that best fits the description of a CNS stimulant that blocks dopamine reuptake is cocaine.
