Morpholine, I believe many friends have the impression that if you have stomach bloating, use morpholine. Morpholine is the trade name of domperidone, which is produced by Xi’an Janssen Pharmaceutical Company. This drug is mainly used for stomach bloating, indigestion, gastroesophageal reflux disease and other diseases, and its mechanism of action is to act as a peripheral dopamine D2 receptor antagonist, which can promote the emptying of the gastroduodenum. When there is a history of gastroesophageal reflux disease, it needs to be treated together with drugs that inhibit gastric acid such as omeprazole; when there is dyspepsia, it needs to be used together with compounded gastrin or multi-enzyme tablets. The usage of morpholine is: 1 tablet 3 times a day, 15-30 minutes before meals.
