Administration of cisapride, 3 x 5 mg in a suspension one day before surgery and 30 mg 3 and 8 hours after abdominal surgery with subsequent administration of 2 x 30 mg in suppositories up to the time when oral ingestion is possible, hastens significantly the restoration of GIT motility as compared with placebo. It can be therefore recommended as effective medication in the prevention of complications caused by impaired motility of the digestive tract.
