Ticalopride is an isomer of the active metabolite of cisapride, which is marketed by Janssen for the treatment of nocturnal heartburn due to gastroesophageal reflux disease. Ticalopride 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 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. Phase II clinical trials of the Ticalopride are being suspended while investigators study reports of adverse events in patients with gastroesophageal reflux disease and diabetes.

Cisapride 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. The Food and Drug Administration (FDA) in America stopped the marketing of cisapride as of 14th July 2000. They had received at least 341 reports of heart rhythm abnormalities and these led to 80 deaths. Other reported adverse effects are: headache, diarrhea, abdominal pain, nausea, constipation. Cisapride for animals has been found helpful in some cases of megaesophagus and is a common treatment for feline megacolon. Clarithromycin, erythromycin, and troleandomycin markedly inhibit the metabolism of cisapride. Concurrent administration of certain anticholinergic compounds, such as belladonna alkaloids and dicyclomine, would be expected to compromise the beneficial effects of cisapride.

Mosapride is a gastroprokinetic agent, a 5-HT4 receptor agonist and 5-HT3 receptor antagonist exhibiting no activity at dopamine D2, 5-HT1 and 5-HT2 receptors. Mosapride stimulates serotonin receptor in the digestive tract and increases acetylcholine release to promote upper digestive tract (stomach and duodenum) and lower digestive tract (colon) motility. It is usually used to treat heartburn, nausea and vomiting caused by chronic gastritis. Mosapride is approved and marketed in the countires of Asia and Latin America.

Itopride is a dopamine D2 receptor antagonist and inhibitor of acetylcholinesterase. It is indicated in the for the treatment of gastrointestinal symptoms caused by reduced gastrointestinal motility, such as functional non-ulcer dyspepsia (chronic gastritis), gastric fullness, rapid satiation, pain or discomfort in the upper abdomen, anorexia, heartburn, nausea, and vomiting. The drug is not approved in the USA or UK but is available in Japan and Western European countries.
