The main function of domperidone tablets is to promote gastric motility and prevent food reflux. Domperidone is a common pro-gastric motility drug that can be considered for treatment in cases of indigestion causing nausea and vomiting. The drug helps increase the tone of the esophageal sphincter and allows food to enter the stomach smoothly. It also enhances the peristaltic function of the stomach and coordinates the movement of the stomach and duodenum, allowing the food to empty as soon as possible. Once the food is emptied, the stimulation of the stomach can be avoided, which not only relieves nausea and vomiting, but also does not affect the secretion of digestive juices. Morpholine is often used in the treatment of gastroesophageal reflux disease, and care should be taken to avoid using it together with anticholinergics during treatment, as this may affect the effect of the drug.
