Antiemetic use
Metoclopramide is commonly used to treat nausea and vomiting (emesis) associated with conditions including: emetogenic drugs, uraemia, radiation sickness, malignancy, labor, and infection.
It is also used by itself or in combination with paracetamol (acetaminophen) for the relief of migraine.
It is considered ineffective in postoperative nausea and vomiting (PONV) at standard doses, and ineffective for motion sickness. In nausea and vomiting associated with cancer chemotherapy, it has been superseded by the more effective 5-HT3 antagonists (e.g. ondansetron).
Prokinetic use
Metoclopramide increases peristalsis of the jejunum and duodenum, increases tone and amplitude of gastric contractions, and relaxes the pyloric sphincter and duodenal bulb. These prokinetic effects make metoclopramide useful in the treatment of gastric stasis (e.g. after gastric surgery or diabetic gastroparesis), as an aid in gastrointestinal radiology by increasing transit in barium studies, and as an aid in difficult small intestinal intubation. It is also used in gastroesophageal reflux disease (GERD/GORD).Other indications
By inhibiting the action of prolactin inhibiting hormone (i.e. dopamine), metoclopramide has sometimes been used to stimulate lactation
