Cisapride.
Renal patients often complain of vague abdominal symptoms compatible with a gastric motility disorder. Cisapride is a recently available prokinetic agent that improves motility and emptying of the upper gastrointestinal tract in patients on long-term dialysis. The drug is extensively metabolized in the liver producing metabolites with minimal pharmacologic activity. Adverse reactions are primarily gastrointestinal in nature and include abdominal cramps, flatulence, and diarrhea.
