Positive and negative symptoms, depression and social disability in chronic schizophrenia: a comparative trial of bromperidol and fluphenazine decanoates.

A 1 year double-blind trial of bromperidol decanoate and fluphenazine decanoate was conducted in the maintenance treatment of 47 outpatients with schizophrenia. Six patients relapsed on bromperidol decanoate and none on fluphenazine decanoate, a difference which is statistically significant. No significant differences in positive and negative symptoms, nor depression measures were found between treatment groups when comparisons were made for change in score from entry to last visit. However, patients on fluphenazine decanoate achieved significantly better changes on social disability (Morningside scale) compared to those on bromperidol decanoate. The incidence of extrapyramidal side-effects was similar in both groups, and no statistically significant differences emerged in body weight change between treatments.
