Amoxicillin can be used to treat gastric erosion, but only as an adjunct, not alone, and it needs to be used specifically under the guidance of a specialist. The actual fact is that it is a type of chronic gastritis, that is, a lesion with gastric mucosal erosion on top of chronic gastritis. The main treatment is to give acid-suppressing drugs combined with drugs that promote mucosal repair. If the patient has gastric mucosal erosion or gastritis and there is clearly a bacterial infection such as Helicobacter pylori infection, anti-infective treatment with amoxicillin can be added, but usually another antibiotic is needed to eradicate Helicobacter pylori, and a specialist needs to be consulted for the specific medication.
