The generic name for morphine is domperidone, which is a medication that promotes gastric motility. Reflux pharyngitis can be treated with medications that promote gastric motility, such as domperidone, which can increase gastric motility and reduce food reflux. Food enters the gastrointestinal tract through the oral esophagus and does not usually return the same way. If the barrier function is reduced, food from the stomach refluxes into the throat, forming reflux pharyngitis. It may cause symptoms such as dry throat, sore throat, hoarseness, and chronic cough. The key to the treatment of the disease is mainly to control gastric acid reflux, and esomeprazole and aluminum phosphate gel can be given, which can reduce the secretion of gastric acid and also protect the gastric mucosa. If necessary, with domperidone, mosapride and other drugs, can promote gastrointestinal power, reduce acid reflux. For symptoms such as dry throat, hoarseness, sore throat, etc., it is recommended to go to the ENT and Gastroenterology Departments of the hospital. For specific medication, please follow your doctor’s instructions.
