title: Lack of effect of 28 days of neuroleptic treatment on platelet benzodiazepine binding sites in schizophrenics.
abstract: Twenty-eight days of neuroleptic treatment of 11 schizophrenics aged 16-23 years did not affect the binding values of 3H-PK 11195 to platelets. This lack of effect was in contrast to reduced peripheral benzodiazepine binding sites (PBS) observed in platelets of schizophrenics medicated over 2 years. These results may indicate that neuroleptic-induced down-regulation of PBS is a time-dependent phenomenon.
