    Abstract:
    Two hundred and forty-two patients with acute schizophrenia were enrolled in a double-blind, comparative, dose-finding study of a novel antipsychotic, remoxipride. Remoxipride was evaluated in a low (30 to 90 mg), medium (120 to 240 mg) and a high (300 to 600 mg) dose range and compared with a haloperidol (15 to 45 mg), which was administered to a similar group of patients. The results support the antipsychotic effect of remoxipride, with maximum efficacy occurring at daily doses between 120 mg and 600 mg. Side-effects were more frequent at doses of remoxipride over 300 mg. In all groups, remoxipride caused consistently fewer extrapyramidal side-effects than haloperidol. The antipsychotic effect of remoxipride may be derived from specific blockade of dopamine D2 receptors in the mesolimbic tract. The findings also suggest that remoxipride may have a therapeutic effect on negative symptoms of schizophrenia.
