Lee: Gastrointestinal Motility Modulating Drugs

Abstract

Gastrointestinal motility modulating drugs include all compounds which have pharmacological activity of modulating (stimulating or inhibiting) gastrointestinal motility. They are mainly used for the treatment of functional gastrointestinal diseases. Gastrointestinal motility modulating drugs include 5HT receptor agonists, antagonists, and antidopaminergic agents. Many new gastrointestinal motility modulating drugs are currently under investigation. The aims of this article are to review the mechanism of action, efficacy and side effects of the gastrointestinal motility modulating drugs.
