The novel antipsychotic drug sertindole has an atypical pharmacological profile. We have estimated striatal D2 dopamine binding in schizophrenic patients treated with sertindole using 123I iodobenzamide (IBZM) SPET. Patients were recruited from a clinical trial of sertindole's tolerability and efficacy. Striatal D2 binding in sertindole-treated patients (n = 5), was compared with previously reported data from clozapine (n = 10); olanzapine (n = 6); typical antipsychotic responsive (n = 10); and risperidone (n = 6)-treated groups. Mean PANSS (structured clinical interview for the positive and negative syndrome scale) scores showed clinical improvement in the sertindole group. Few extrapyramid..View full abstract
