Abstract

Clozapine and melperone exhibit higher affinity for the dopamine D4 receptor than the D2 receptor. Raclopride and chlorpromazine exhibit high selectivity for the dopamine D2 receptor. D4 selective compounds have a low incidence of EPS and TD, whereas D2 selective compounds have a higher incidence. It is postulated that a drug's affinity for the D4 receptor may confer antipsychotic activity and its affinity for the D2 receptor may confer EPS and/or TD activity.
