HealingWell.com Forum > Diseases & Conditions > GERD - Heartburn > Prokinetic agents - drugs that tighten the lower esophageal sphincter. These drugs work by tightening the lower esophageal sphincter, which helps prevent acid from washing back up into the esophagus. They also slightly increase the contractions of the esophagus and the stomach to help empty the stomach faster. Prokinetic agents include metoclopramide (also known as Reglan), bethanechol (Duvoid) and tegaserod (Zelnorm).
Gastroesophageal Reflux Disease (GERD) is caused by reflux of stomach acid into the esophagus. In most sufferers this is due to a relaxation of the lower esophageal sphincter (LES) that opens to allow food and liquids to pass into the stomach, and closes to prevent food and stomach acid from flowing back into the esophagus. This relaxation of the LES happens a few times each day in people without GERD.
