Chronic superficial gastritis and chronic atrophic gastritis are two diseases, and the difference between them is whether there is atrophy of the gastric mucosa. At present, there is no drug for atrophic gastritis that can effectively reverse the atrophy of the gastric mucosa. For these two kinds of gastritis, mainly for the patient’s clinical manifestations of medication, there are the following three types of drugs: 1, drugs to inhibit gastric acid secretion, such as proton pump inhibitors, such as omeprazole enteric capsules. 2, drugs to protect the gastric mucosa, such as magnesium aluminum carbonate tablets, aluminum phosphate gel. 3, drugs to promote gastrointestinal tract dynamics, such as trimebutine maleate.
