Preliminary note on the antipsychotic efficacy of bromperidol

Bromperidol was administered to 20 acute and chronic psychotic inpatients during six to eight weeks at a mean daily dose of 18 to 10 mg. The neuroleptic was given orally or intramuscularly once a day (in the morning in order to evaluate its therapeutic and side effects). In 13 patients, bromperidol was substituted for haloperidol; in 7 cases, it was given immediately after the washout period. Descriptive psychopathology was complemented with quantitative psychopathology (ad hoc 29-item scale, AMDP Psychopathology Scale, Bf/Bf' Mood Scales). According to a preliminary analysis of data, both descriptive and psychometric, bromperidol seems to be a potent antipsychotic drug without disturbing adrenolytic side-effects or sedation, with classical extrapyramidal effects of the hypertonia type.
