Double-blind comparison of bromperidol and perphenazine.
Within the scope of a clinical double-blind study, effects and side effects of Bromperidol and Perphenazine were compared. Forty newly-hospitalized schizophrenic patients were included in the trial. Assessments were made on days 0, 2, 5, 10, 20, and 30. Data were documented by means of the AMP system, the EPRS scale of Simpson and Angus, and a Brief Ward Behaviour Rating Scale. Laboratory tests and ECGs were performed before and after treatment. Treatment was scheduled for 30 days and dosages were established depending on effects and side effects. We found a therapeutic effective mean daily dose of 6 mg for Bromperidol and 20 mg for Perphenazine. Both substances caused autonomic and extrapyramidal side effects and, in a few patients, temproary fatigue. The employed dosage caused no strong sedation. To sum up, Bromperidol and Perphenazine can be described as highly potent and well tolerated antipsychotic drugs. We observed stronger efficacy and earlier onset of action with Bromperidol. The superior effect of Bromperidol cannot be explained by a higher dosage as compared with Perphenazine, since both substances showed a similar severity of extrapyramidal side effects, and the dosage of both substances was established individually for each patient, depending on effects and side effects.
