The authors evaluated the in vivo effects of the new drug Cisapride on gastrointestinal hormone release in the mini-pig. Cisapride has been reported to stimulate and coordinate peristalsis of the GI tract. Selective endoluminal perfusion with Cisapride solution of the isolated but not denervated gastric antrum, duodenum and distal ileum demonstrated a significant increase of gastrin levels following perfusion of the gastric antrum and a decrease in vasoactive intestinal peptide following perfusion of the duodenum, only at very high doses.

The influence of the prokinetic drug cisapride on the release of gastrointestinal hormones was studied in volunteers. First, acute effects of single doses of cisapride compared with saline were investigated. Cisapride at doses of 8 mg and 20 mg intravenously significantly increased plasma concentrations of pancreatic polypeptide (hPP) by 145% and 146%, respectively. Cholecystokinin (CCK) levels were increased by 176% at 8 mg cisapride, whereas gastrin and insulin levels remained unchanged. Enhancement of PP and CCK secretion was almost completely abolished by pretreatment with 1 mg atropine. Carbachol (250 micrograms subcutaneously) increased PP release by 62% but did not affect the other hormones. Second, the influence of a 1-week treatment (10 mg three times daily, given orally) on plasma hormone levels was studied. After 1 week the postprandial CCK release was diminished by 58%. Basal levels and postprandial responses of gastrin, PP, and insulin were not altered by prolonged cisapride administration. It is concluded that acute application of cisapride stimulates secretion of PP and CCK via atropine-sensitive mechanisms and that chronic treatment with cisapride diminishes CCK release by an unknown mechanism.

Cisapride is a novel gastrointestinal prokinetic drug. The aim of the present study was to investigate gastric emptying time and secretion of gastrointestinal hormones (Gastrin, Motilin, Glucagon) after single oral intake of 5 mg or 10 mg cisapride. The healthy men aged 23-55 years participated the study. The gastric emptying time and gastrointestinal hormones were measured by gamma-camera radioisotopic technique and radioimmunoassay, respectively. The half time of emptying phase was reduced from 31.78 min to 29.88 min, and emptying rate increased in 10 mg cisapride group. There was a tendency that cisapride accelerated a stimulation of Motilin secretion.
