Domperidone tablets should be taken orally 15 or 30 minutes before meals. Domperidone tablets work primarily to promote gastric emptying and are best absorbed when taken orally on an empty stomach. If taken after a meal, absorption will actually be delayed. Domperidone can act directly on the stomach wall and intestinal wall, can make the peristalsis and tension of the gastrointestinal tract increase, and then increase the peristalsis of the gastric sinus and duodenum, in coordination with the pyloric contraction at the same time, but also can enhance the lower esophageal sphincter tension and peristalsis, and promote gastric content as soon as possible discharge, but also can inhibit nausea and vomiting. If Domperidone is taken orally after meals, the therapeutic effect will be reduced due to the increased secretion of gastric acid. It is recommended to use the drug under the guidance of a doctor to avoid reducing adverse drug reactions such as dry mouth, insomnia, skin rash and tardive dyskinesia.
