Dopamine-active drugs produce predictable changes in CSF prolactin, and these alterations are in the same direction as the plasma prolactin responses to similar compounds. The decrease in prolactin with piribedil apparently reflects direct dopamine receptor stimulation by the drug, while the concomitant decrease in HVA accumulations may represent a secondary decrease in dopamine synthesis. Increased prolactin in the pimozide-treated patients would be compatible with dopamine receptor blockade, even though the HVA accumulations were not consistently elevated. Prolactin response may provide a relatively direct and sensitive index of pharmacologically-induced alterations in central dopamine receptor activity.
