timiperone and Chronic-Disease

The efficacy of timiperone in schizophrenia as compared with perphenazine was assessed in a double-blind fashion in 205 patients throughout a 12-week treatment period. More than half of the subjects were chronic schizophrenics. Global improvement in the timiperone treatment group was superior to that in the perphenazine group in view of a lower rate of aggravation. With regard to overall safety and general usefulness rating, there were no significant differences between the two drug treatments. However, timiperone showed less frequency of excitability, irritability, anxiety and anorexia than perphenazine on occasions during the 12 week treatment period. From these results it may be concluded that the efficacy of timiperone could be superior or equivalent to that of perphenazine which has been confirmed to be of use as an antipsychotic.
