[Effect of nootropic drugs on the dopamine release and dopamine uptake in structures of the rat striatum].

Nootropics increase the overflow of dopamine from rat striatum slices in a concentration dependent manner, but without relation to their clinical effectiveness. The influence of a nootropic drugs and of amphetamine on the stimulus induced dopamine release points to a relationship between nootropic and nooanaleptic activity, on the one hand, and transmitter release, on the other. Dopamine re-uptake is not altered by nootropics like piracetam.
