Reglan is the brand name for the drug metoclopramide. It is classified as a prokinetic and antiemetic medication. The drug works by blocking dopamine receptors in the chemoreceptor trigger zone. It also enhances the activity of the upper gastrointestinal tract. By increasing gastric emptying and intestinal motility it helps prevent nausea and vomiting. Clinically it is used to treat gastroesophageal reflux disease and diabetic gastroparesis. Its effect on the central nervous system reduces the sensation of nausea. The overall result is improved digestive function and symptom relief.

Reglan is the brand name for metoclopramide, a medication that enhances gastrointestinal motility by acting as a dopamine d2 receptor antagonist in the chemoreceptor trigger zone. It blocks dopamine signals in the brain, which reduces nausea and vomiting and increases the strength of stomach and intestinal contractions. This dual effect helps patients with delayed gastric emptying or gastroesophageal reflux disease experience faster digestion and reduced symptoms. Reglan also stimulates acetylcholine release, further promoting gastric emptying and intestinal movement. By modulating the chemoreceptor zone, it prevents the activation of pathways that trigger emesis, making it useful for both diagnostic and therapeutic purposes. Overall the drug provides symptomatic relief while supporting the normal coordination of digestive tract activity through central receptor antagonism.

Common side effects include drowsiness and dizziness. Some people report nausea or diarrhea. Headache and dry mouth are also frequently reported. Muscle stiffness or tremor may occur in certain individuals. Restlessness or an inability to sit still can be observed. Rarely movement disorders such as tardive dyskinesia have been documented.
