Amphetamine-type stimulants are defined by their impact on dopamine in the brain, particularly by increasing dopamine availability either by releasing it or by blocking its reuptake. Methamphetamine and dextroamphetamine are classic members of this group that drive release of dopamine into the synapse. Methylphenidate, while it works primarily by blocking the dopamine transporter to prevent reuptake, is commonly included in this broader stimulant category because it produces similar dopaminergic effects. Together, these examples illustrate how this class raises dopamine levels to produce stimulating effects.

Cocaine also blocks dopamine reuptake, but it is not categorized with the amphetamine family and has a distinct pharmacological profile. Ketamine and PCP are dissociative anesthetics that act mainly as NMDA receptor antagonists, not as dopamine reuptake blockers, so they don’t fit this description.
