Eleven patients with Huntington's disease and nine patients with tardive dyskinesia participated in a randomised double-blind crossover trial of sulpiride (as sole antidopaminergic therapy) versus placebo. Although functional improvement was not seen in Huntington's disease patients, sulpiride reduced movement count and total dyskinesia score in both conditions. Sulpiride differs pharmacologica...
Dopamine improves learning and memory formation. The neurophysiological basis for these effects might be a focusing effect of dopamine on neuroplasticity: Accordingly, in humans L-dopa prolongs focal facilitatory plasticity, but turns nonfocal facilitatory plasticity into inhibition. Here we explore the impact of D(1) receptors on plasticity. Nonfocal plasticity was induced by transcranial dire...
The human ether-a-go-go-related gene (hERG) channel is important for repolarization in human myocardium and is a common target for drugs that prolong the QT interval. We studied the effects of two antipsychotics, tiapride and sulpiride, on hERG channels expressed in Xenopus oocytes and also on delayed rectifier K(+) currents in guinea pig cardiomyocytes. Neither the amplitude of the hERG outwar...
It is well documented that sulpiride causes hormonal adverse events, like amenorrhoea and galactorrhea, due to its mechanism of action. Furthermore, risperidone can produce amenorrhoea and galactorrhea also, due to its mechanism of action, which differs from that of sulpiride. This case report is of a patient that was treated with large doses of sulpiride, but did not develop an adverse event l...
The effects of hyperprolactinemia on the release of immunoreactive luteinizing hormone-releasing hormone (LH-RH) and luteinizing hormone (LH) in response to iv injection of 20 mg conjugated estrogens (Premarin) were studied. Five normal cycling women were injected with Premarin on the morning of the 7th day of the first cycle (control cycle), and then the plasma levels of LH-RH, LH, and prolact...
Previously, we have found that some antipsychotic drugs are able to inhibit glucocorticoid receptor (GR)-mediated gene transcription. Since these drugs are known not only to inhibit hypothalamic-pituitary-adrenal (HPA) axis activity, but also to modulate the immunological system, the aim of the present study was to compare the effect of sulpiride and clozapine on GR function under basal culture...
The abnormal involuntary movements in tardive dyskinesia can be reduced by the dopamine antagonist drugs, phenothiazines and butyrophenones, but most cause an increase in Parkinsonian signs. Sulpiride, a benzamide derivative, and selective antagonist of D2 receptors had a significantly beneficial effect on most of 15 patients (p less than 0.01). In 12 patients the improvement was marked. The re...
