The triple therapy of Helicobacter pylori has been eliminated at this stage due to its low sterilization eradication rate. At present, the commonly used quadruple therapy contains bismuth, that is, an acid inhibitor, plus a bismuth agent, plus two antibiotics. There are many commonly used acid inhibitors, such as rabeprazole, omeprazole, pantoprazole, esomeprazole, etc. Antibiotics include amoxicillin, clarithromycin, metronidazole, furazolidone, tetracycline, etc. Bismuth is generally used bismuth potassium citrate, colloidal bismuth pectin, etc. If there is no penicillin allergy, must choose amoxicillin, its resistance rate is very low and side effects are small, eradication rate is relatively high.
