The science

How it works, mechanistically.

Core mechanism

Blocks the reuptake of dopamine and norepinephrine by inhibiting their respective transporters (DAT and NET) in the prefrontal cortex and striatum. Unlike amphetamines, methylphenidate primarily acts as a reuptake inhibitor rather than a releaser of catecholamines, resulting in increased synaptic dopamine and norepinephrine concentrations.
