At present, quadruple therapy is mostly used to treat H. pylori infection, i.e. 2 antibiotics + proton pump inhibitor + bismuth, and the specific treatment plan should be in accordance with the principle of individualization.
1. Antibiotics: amoxicillin + levofloxacin or amoxicillin + clarithromycin can be chosen, which have better bactericidal effect on H. pylori.
2. Proton pump inhibitors: commonly used drugs are rabeprazole, omeprazole, etc. The main function is to reduce the secretion of gastric acid in the cells of the stomach wall.
3. Bismuth: commonly used drugs are bismuth potassium citrate and bismuth pectin, which can also form a diffuse protective layer in the acidic environment of the stomach and thus protect the gastric mucosa.
The above drugs are prohibited for those who are allergic to them and should be taken in accordance with medical advice. If the patient is diagnosed with Helicobacter pylori infection, it is recommended to go to the regular hospital in time, under the guidance of the doctor for targeted treatment.
