The antipsychotic effect of neuroleptic drugs is well established (Delay and Deniker 1957; Klein and Davis 1962). The individual response to treatment with neuroleptic drugs is, however, highly variable. Some patients do not respond to treatment, and in some patients severe side effects are recorded. For such reasons there is a need for useful methods to examine the mechanism of antipsychotic drug action in patients and for measures to guide the determination of proper dosage. During the past 20 years techniques have been available for the measurement of drug concentrations in body fluids. Despite a large number of studies on the relationships between serum drug concentrations and antipsychotic effect, no consistent relationships have been generally confirmed (Dahl 1986).
