Gastrodin, or mosapride citrate tablets, is a drug commonly used for the relief of gastrointestinal symptoms. It works mainly through selective 5-hydroxytryptamine 4 agonists, which can promote the release of acetylcholine from the vagus nerve to facilitate the movement of the gastrointestinal tract in order to work, and can significantly improve the symptoms that appear in patients with dyspepsia, such as heartburn, belching, nausea, vomiting, and abdominal distention. The drug does not affect the secretion of gastric acid by the cells of the stomach lining, and is commonly used clinically in the treatment of patients with gastroesophageal reflux, gastroparesis, and post-gastrectomy complications. This drug is rapidly absorbed by the body after oral administration, has a fast action, is excreted through the kidneys and gastrointestinal tract, and can cause rashes, dry mouth, dizziness and other disorders. Those who are ineffective after 2 weeks of taking Mosapride citrate tablets should not continue taking them.
