Definition
A substituted benzamide used for its prokinetic properties. It is used in the management of gastroesophageal reflux disease, functional dyspepsia, and other disorders associated with impaired gastrointestinal motility. (Martindale The Extra Pharmacopoeia, 31st ed)
Description
In many countries (including Canada) cisapride has been either withdrawn or has had its indications limited due to reports about long QT syndrome due to cisapride, which predisposes to arrhythmias. The FDA issued a warning letter regarding this risk to health care professionals and patients.

General Information
- Metabolism: Hepatic. Extensively metabolized via cytochrome P450 3A4 enzyme. Half Life: 6-12 hours
- Uses/Sources: For the symptomatic treatment of adult patients with nocturnal heartburn due to gastroesophageal reflux disease.
- Symptoms: Diarrhea, upset stomach, stomach discomfort, vision changes, constipation.
- Treatment: In instances of overdose, patients should be evaluated for possible QT prolongation and ventricular arrhythmias, including torsades de pointes. Treatment should include gastric lavage and/or activated charcoal, close observation and general supportive measures. (L1712)
- Route of Exposure: Cisapride is rapidly absorbed after oral administration, with an absolute bioavailability of 35-40%.

Cisapride acts through the stimulation of the serotonin 5-HT4 receptors which increases acetylcholine release in the enteric nervous system (specifically the myenteric plexus). This results in increased tone and amplitude of gastric (especially antral) contractions, relaxation of the pyloric sphincter and the duodenal bulb, and increased peristalsis of the duodenum and jejunum resulting in accelerated gastric emptying and intestinal transit. |
