In order to elucidate the differences between the in vivo and in vitro pharmacological characteristics of CPZ , we used a radioreceptor assay to measure the anti - D2 activity and the anti - 5 - HT2A activity of CPZ and five major metabolites of CPZ , and compared the results to the anti - D2 activity and anti - 5 - HT2A activity of risperidone , zotepine , perospirone , the major metabolites of each of these drugs , and olanzapine , bromperidol , and haloperidol .
