Alizapride is a potent antiemetic, acting as a dopamine receptor antagonist on the chemoreceptor trigger zone with few gastrokinetic properties. Little is known of its activity on the human sphincter of Oddi (SO). The aim of this study was to assess the effect of alizapride on SO motor function and to evaluate a possible use of alizapride in premedication for endoscopy of the upper digestive tract. We selected ten patients who underwent retrograde cholangiopancreaticography, but had no evidence of biliary or pancreatic disease. Endoscopic manometry was applied before and for 10 min after administration of alizapride 100 mg i.v. No significant modification of basal pressure or phasic activity was observed. Alizapride can be proposed as an antiemetic in patients with biliary disorders.

A series of studies was carried out in infants and children suffering from gastro-oesophageal reflux to assess the therapeutic efficacy and tolerability of alizapride, a recently developed dopaminergic-receptor blocker. Investigational techniques such as manometry, pH monitoring, endoscopy and scintigraphy were used to evaluate a prokinetic activity of the drug and its effects on oesophageal and gastric motility when given by the intravenous and oral routes. Preliminary findings indicate that alizapride had a significant effect on lower oesophageal sphincter pressure and peristaltic wave amplitude, but the evidence for an effect on gastric motility was less clear.
