Remoxipride acts as an antagonist at the D2 dopamine receptor. It is believed that overactivity of dopamine systems in the mesolimbic pathway may contribute to the "positive symptoms" of schizophrenia (such as delusions and hallucinations), whereas problems with dopamine function in the mesocortical pathway may be responsible for the "negative symptoms", such as avolition, flat emotional response and alogia. Therefore, by decreasing the levels of dopamine in these pathways, it is thought that remoxipride is able to reduce the symptoms of schizophrenia, particularily the "positive symptoms". (en)
