A double-blind comparison of flupenthixol decanoate and fluphenazine decanoate in the treatment of chronic schizophrenia.

Sixty-four chronic stabilised schizophrenics were studied for 18 months in order to assess the possible difference in therapeutic effects and side effects between flupenthixol decanoate and fluphenazine decanoate. Although certain differences in the BPRS sub-scores in favour of flupenthixol were present at various stages in the study, there was no significant difference between the two drugs in the overall antipsychotic scores at the end of the assessment period; however, more patients on fluphenating required additional therpay for depression or anxiety during the trial period.
