There is no scientific basis for H. pylori prescriptions; treatment is a quadruple therapy containing bismuth, which cannot be eradicated with medication alone.
Quadruple therapy means a proton pump inhibitor, two antibiotics, and a bismuth agent. Antibiotics can choose any two of clarithromycin, metronidazole, tetracycline, furazolidone, levofloxacin, tinidazole, amoxicillin, proton pump inhibitors can choose omeprazole, rabeprazole, lansoprazole, etc., and bismuth can choose bismuth pectin, bismuth potassium citrate and so on.
The cycle of treatment for diseases caused by Helicobacter pylori is usually 10~14 days and needs to be reviewed. Infection with Helicobacter pylori needs to receive professional treatment, under the guidance of a doctor, and not abuse the prescription. Drug selection for the elderly should pay attention to liver and kidney function and other comorbidities.
