Compatibility of high doses of both oral domperidone and neuroleptics in chronic psychotics

Twenty chronic schizophrenic inpatients who were being treated with high doses of neuroleptics and of whom seven had extra-pyramidal symptoms in spite of anti-Parkinsonian therapy, were given oral domperidone (50 mg t.d.s. for 2 weeks) for the relief of chronic dyspepsia. The dyspepsia symptoms were markedly improved, no side effects were seen and, even at high doses, domperidone did not intensify the existing extra-pyramidal side effects of the neuroleptics or produce new ones.
