title: Remoxipride. A review of its pharmacodynamic and pharmacokinetic properties, and therapeutic potential in schizophrenia.
abstract: Remoxipride is a substituted benzamide of the same class as sulpiride, and has a pharmacodynamic profile consistent with central antidopaminergic activity. It is a weak, but relatively selective, central dopamine D2-receptor antagonist and appears to have preferential affinity for extrastriatal dopamine D2-receptors. It also has marked affinity for central sigma receptors. Clinical data from noncomparative and comparative studies show that remoxipride has antipsychotic acticvity in patients with chronic schizophrenia, and acute exacerbation of chronic schizophrenia, with activity on both positive and negative symptoms. Its overall efficacy in these studies was similar to that of haloperidol. Importantly, however, remoxipride produced a substantially lower incidence of extrapyramidal effects than haloperidol. Further long term comparative studies are required to ascertain the relative suitability of remoxipride for preventing relapse in psychotic patients, and to determine whether tardive dyskinesia occurs in remoxipride recipients--the latter has not been reported with remoxipride to date. Thus, while further experience (particularly of a long term comparative nature) is needed, at present remoxipride appears to offer an important tolerability advantage over haloperidol.
