Clinical use of the radioreceptor assay for neuroleptics

Abstract

The potential clinical utility of the radioreceptor assay for neuroleptics (NRRA) was examined. The NRRA was able to detect neuroleptic activity in blood specimens from patients receiving a variety of neuroleptic medications. For each medication, mean plasma neuroleptic activity was lower in patients showing a poor response to treatment than in those showing a good response. Because the range of plasma neuroleptic activities found was quite different from drug to drug, it appears that results obtained by the NRRA must be standarized for each drug.
