A controlled clinical study--phase III--with bromperidol was conducted on 30 male patients with a diagnosis of schizophrenia of different subtypes, realized by psychiatric assessments and by laboratory measures over an eight-week investigational period. A global improvement (from very much up to moderately) was achieved in 76% of the patients; two patients dropped out. The optimal dosage of bromperidol seemed to lie between 4 and 6 mg/day. The adverse effects were confined to moderate extrapyramidal symptoms in the extent of a higher dosage. Bromperidol appears to be a potent longacting neuroleptic drug without essential psychomotor damping, anxiolytic and hypnosedating properties, but with a strong antipsychotic potential against the basic schizophrenic disintegration. It is mainly indicated in paranoia, depressive-paranoia and simple forms of schizophrenia.

Bromperidol is a close structural analogue of haloperidol. Both agents possess similar pharmacodynamic properties which are consistent with central antidopaminergic activity. The available clinical data from non-comparative and comparative trials have shown that bromperidol possesses antipsychotic activity. Its overall efficacy was slightly greater than chlorpromazine and perphenazine, and similar to or slightly better than haloperidol in a small number of comparative studies. Bromperidol frequently displayed a faster onset of action than these comparative agents and there have been reports of bromperidol causing an activating effect. However, extrapyramidal side effects occurred with similar frequency and severity after bromperidol compared with the 3 reference drugs. Data from additional controlled clinical trials are required to confirm the comparative antipsychotic efficacy of bromperidol and to assess whether it possesses any advantages in certain sub-types of schizophrenia.

Bromperidol therapeutic efficacy, and tolerance was studied by means of a 3-month open trial on 25 chronic psychotic female inpatients from a room at San Juan ward for medium to extensive length of stay, The Braulio A. Moyano National Psychiatric Hospital, Buenos Aires. This drug was administered orally on a single 10- to 35 mg night dose. No effect whatsoever was observed on periodic catatonia. However, its being well-tolerated and effective on chronic psychotic patients, coupled to the "bonus" of a single daily dose, turns BP into a suitable alternative drug for Haloperidol when dealing with schizophrenia, and delusions with no deficitary evolution.

Bromperidol is a close structural analog of haloperidol. The authors studied the effects of levomepromazine and thioridazine, which are frequently added to other neuroleptics as sedatives, on plasma concentrations of bromperidol and its reduced metabolite. The subjects were 26 inpatients with schizophrenia receiving bromperidol, 12 to 24 mg/day, for 1 to 19 weeks. In 10 cases, 50 mg levomepromazine per day and in nine cases, 50 mg thioridazine per day were coadministered for 1 week. In seven cases, both drugs were coadministered with > or = 2-week intervals. Plasma concentrations of bromperidol and reduced bromperidol were measured by a high-performance liquid chromatographic method. Levomepromazine (n = 17) significantly (p < 0.001) increased plasma concentrations of bromperidol (7.3 +/- 4.1 versus 10.2 +/- 4.8 ng/ml) and reduced bromperidol (1.8 +/- 1.4 versus 4.5 +/- 3.3 ng/ml). Thioridazine (n = 16) did not significantly change plasma concentrations of bromperidol (9.1 +/- 5.7 versus 8.6 +/- 5.5 ng/ml), while those of reduced bromperidol could not be measured because of interfering peaks. The current study suggests that levomepromazine, but not thioridazine, increases plasma concentrations of bromperidol and reduced bromperidol by inhibiting the metabolism of these compounds.
