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).
These muscle fibers are called the lower esophageal sphincter (LES). When this ring of muscle does not close all the way, stomach contents can leak back into the esophagus. This is called reflux or gastroesophageal reflux. Reflux may cause symptoms. Harsh stomach acids can also damage the lining of the esophagus.
