GENERIC NAME: metoclopramide
BRAND NAME: Reglan, Metozolv ODT, (Reglan ODT, Octamide, and Maxolon are discontinued)
DRUG CLASS AND MECHANISM: Metoclopramide is a "prokinetic" drug that stimulates the muscles of the gastrointestinal tract including the muscles of the lower esophageal sphincter, stomach, and small intestine by interacting with receptors for acetylcholine and dopamine on gastrointestinal muscles and nerves.
The lower esophageal sphincter, located between the esophagus and the stomach, normally prevents reflux of acid and other contents in the stomach from backing up into the esophagus. In patients with gastroesophageal reflux disease (GERD), a weakened lower esophageal sphincter allows reflux of stomach acid into the esophagus, causing heartburn and damage to the esophagus (esophagitis). Metoclopramide decreases the reflux of stomach acid by strengthening the muscle of the lower esophageal sphincter. Metoclopramide also stimulates the muscles of the stomach and thereby hastens emptying of solid and liquid meals from the stomach and into the intestines.
In some patients, particularly those with diabetes, damage to nerves in the stomach can interfere with function of the muscles and cause delayed emptying of the stomach, resulting in nausea, vomiting, a sense of abdominal fullness and distention, and heartburn (diabetic gastroparesis). Metoclopramide can be effective in relieving the symptoms related to diabetic gastroparesis by stimulating more rapid emptying of the stomach as well as decreasing the reflux of stomach acid into the esophagus. Dopamine receptors on nerves in the brain are important in producing nausea. Metoclopramide interacts with the dopamine receptors in the brain and can be effective in treating nausea. The FDA approved metoclopramide in June 1985.
