Open study with bromperidol (C-C 2489), a new neuroleptic, for the determination of the neuroleptic threshold and the neuroleptic-therapeutic range.

In an open study involving 30 schizophrenic patients the neuroleptic threshold dose (measured via Haase's graphopathological test), the maximum dose, and the maintenance dose were determined. The neuroleptic threshold dose was 5.6 mg/day (0.08 mg/kg body weight); the maximum dose was 11 mg/day (0.16 mg/kg body weight); and the maintenance dose was 6 mg/day (0.09 mg/kg body weight). With reference to the effectiveness, good to very good results were obtained in 19 cases. Regarding side effects 15 patients complained of extrapyramidal disturbances, this was to be expected in view of the study design aiming at the determination of the maximum dose level. When administered in one single dose in the evening, bromperidol influenced the night sleep positively, so that sleep-inducing drugs could be reduced, and, in some cases, even dispensed with.

Neuroleptic potency of bromperidol.

The following statements can be made on the basis of our study. 1. The butyrophenone bromperidol is an absolutely effective drug of the series of very high-potency neuroleptics, with a mean neuroleptic threshold dose of 5.6 mg/day. The mean optimum dose is 6 mg/day, and the mean maximum dose reaches 11 mg/day, i.e. twice the neuroleptic threshold dose. 2. The substance is generally well tolerated; when it was administered to one third of all cases in one single dose in the evening, it not only had the same beneficial neuroleptic-antipsychotic effect as on administration t.i.d., but also positively influenced sleep, so that sleep-inducing drugs could be reduced and, in some cases, even dispensed with. This relatively long-lasting effect confirms the finding made in animal experiments.

The purely neuroleptic effects and its relation to the "neuroleptic threshold".

Since 1953 when for the first time author pointed at correlation between clinical-neuroleptic effectiveness and the extrapyramidal system, more than 50,000 investigations with 30 different short-term and long-term neuroleptics have been carried out on approximately 850 schizophrenics whose extrapyramidal fine movements were tested according to author's handwriting-test. The results have been comprehended by author as follows: 1. the neuroleptic threshold; 2. the neuroleptic potency according to the neuroleptic threshold; 3. the neuroleptic therapeutic range; 4. the disposition to the neuroleptic threshold-dosage.
