Pindolol augmentation in aggressive schizophrenic patients: a double-blind crossover randomized study.

Treatment of aggression in schizophrenic patients is a major challenge. We sought to examine the efficacy of augmentation of antipsychotic treatment with pindolol in the amelioration of aggression. Thirty male inpatients meeting DSM-IV criteria for schizophrenia, aged 20-65 years involved in four or more aggressive incidents in the two previous months, were enrolled in a double-blind crossover study.
