Action: How Metoclopramide Injection works

Metoclopramide Injection belongs to a group of medicines known as antiemetics. Antiemetics stop or prevent nausea and vomiting.

This medicine works by blocking the action of a chemical in the brain which causes nausea and vomiting. It also acts in the stomach and upper intestine to increase muscle contractions.

It stimulates motility of the upper gastrointestinal tract without stimulating gastric, biliary or pancreatic secretions. The rate of gastric emptying is increased due to increased peristalsis of the jejunum and duodenum. The tone and amplitude of gastric contractions are increased, with the relaxation of the pyloric sphincter and duodenal bulb. These effects combine to result in decreased intestinal transit time.

Metoclopramide Injection contains metoclopramide hydrochloride 5 mg/ mL and sodium chloride in water for injections. It does not contain a preservative.
