Reflux esophagitis treatment is mainly to reduce reflux and reduce gastric mucosal irritation. The main drugs used to reduce gastric reflux are those that promote esophageal and gastric emptying, which are commonly used in clinical practice, including gastroflucan, domperidone, cisapride, etc. These drugs can promote esophageal and gastric emptying, thus reducing gastroesophageal reflux. Drugs to reduce gastric acid mainly include neutralizing gastric acid and inhibiting gastric acid secretion, among which drugs to neutralize gastric acid include aluminum hydroxide gel, oxidase, etc., so as to reduce the damage of acidic gastric contents to esophageal mucosa. Drugs that inhibit gastric acid secretion include famotidine, metformin and proton pump inhibitors such as omeprazole, pantoprazole, lansoprazole, etc.
