Cisapride tartrate is chemically related to metoclopramide, but unlike metoclopramide, it does not cross the blood-brain barrier or have antidopaminergic effects. Cisapride is a serotonin-4 (5-HT4) receptor agonist. Cisapride was indicated for the symptomatic treatment of adult patients with nocturnal heartburn due to gastroesophageal reflux disease.

Cisapride for animals has been found helpful in some cases of megaesophagus and is a common treatment for feline megacolon.

Concurrent administration of certain anticholinergic compounds, such as belladonna alkaloids and dicyclomine, would be e......
