Cisapride

Cisapride is a gastroprokinetic agent, a drug that increases motility in the upper gastrointestinal tract. It acts directly as a serotonin 5-HT4 receptor agonist and indirectly as a parasympathomimetic. Stimulation of the serotonin receptors increases acetylcholine release in the enteric nervous system. It has been sold under the trade names Prepulsid (Janssen-Ortho) and Propulsid (in the United States). It was discovered by Janssen Pharmaceuticals in 1980. In many countries, it has been either withdrawn from the market or had its indications limited due to incidence of serious cardiac side-effects. Propulsid was linked to children's deaths.
