Remoxipride in schizophrenia. A preliminary report.

Remoxipride, a substituted benzamide with preferential action on mesolimbic dopaminergic brain functions, was investigated in an open study in 10 schizophrenic patients. After 1 week with placebo, patients received remoxipride in a increasing doses from 150 to maximal 450 mg daily for 6 weeks. In six patients a clinically relevant reduction of psychotic symptomatology as assessed with the BPRS was observed. Few adverse effects were noted; extrapyramidal symptoms, if present, decreased during treatment, while the reported side effects were only mild. No consistent changes in plasma levels of prolactin and HVA were found.
