Metoclopramide is called a 'prokinetic' drug that helps in invigorating the muscles in the gastrointestinal tract, counting the muscles in the stomach, lower esophageal sphincter, as well as the small intestine by means of acting together with the dopamine and acetylcholine receptors on the nerves and the gastrointestinal muscles.
It may be noted here that the lower esophageal sphincter is positioned between the stomach and the esophagus and it generally puts off the reflex of acids as well as other substances in the stomach from going back into the esophagus. In people suffering from gastroesophageal reflux disease (GERD), a debilitated lower esophageal sphincter allows the backward flow of stomach acid into the esophagus resulting in heartburn as well as esophagitis (a condition wherein the esophagus is damaged). Metoclopramide helps in reducing the reflux or backward flow of stomach acid by means of fortifying the lower esophageal sphincter muscle. In addition, this medication excites the stomach muscles and, by this means, speeds up evacuating the solid as well as fluid meals from the stomach into the intestines.
In a number of patients, especially people having diabetes, injuries to the nerves present in the stomach may possibly hinder the functioning of the muscles and result in delaying the evacuation of the substances in the stomach. This often causes vomiting, nausea, heartburn (also known as diabetic gastroparesis) and a feeling of fullness as well as distention in the abdomen. Using metoclopramide may prove to be helpful in alleviating the symptoms associated with diabetic gastroparesis by encouraging faster evacuation of the stomach, in addition to restricting the stomach acid from flowing back into the esophagus. Dopamine receptors found on the nerves within the brain are vital in generating a queasy feeling. Metoclopramide works in conjunction with the dopamine receptors and may prove to be helpful in treating queasiness. Metoclopramide was approved for sale and use by the Food and Drug Administration in June 1985.
