Which neurotransmitter is affected by antipsychotic medications?

Antipsychotic drugs, neurotransmitters, and schizophrenia. Inhibition of central dopamine functions appears to be a common basic property of antipsychotic drugs. The mesolimbic and nigrostriatal portions of the dopaminergic system are probably the main targets for the mental and the extrapyramidal actions, respectively, of these drugs.
