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).
Acid reflux occurs when the lower esophageal sphincter muscle (LES), located at the bottom of your esophagus, relaxes abnormally, allowing stomach acid to flow back into your esophagus. The LES works like a valve, connecting the esophagus to the stomach.
