Cisapride differs from metoclopramide in which of the following aspect?

Cisapride does not block the dopamine receptors, thus does not cause extrapyramidal symptoms or alter the prolactin levels. Though its effects on the stomach and small bowel motility are similar to metoclopramide, the colonic motility is increased with cisapride (no effect with metoclopramide). Like metoclopramide, its actions on the gut are blocked by atropine.
