title: Repeated high dosage naloxone treatment without therapeutic efficacy in schizophrenic patients.
abstract: 6 schizophrenic patients were treated in a cross-over design for 4 days each with 20 mg naloxone or placebo. No patient showed a significant change of his or her psychotic behaviour. This result is not in agreement with an antipsychotic action of the opiate antagonist.
