Gastritis is a common type of benign disease. There are generally three types of drugs used to treat gastritis: the first type, anti-inflammatory drugs. Since the bacteria that form gastritis are more commonly known as Helicobacter pylori, a combination of antimicrobials is generally required, the most commonly used being levofloxacin and amoxicillin, or a combination of levofloxacin and cephalosporins can be used for anti-inflammatory treatment. The second category, the anti-acid drugs, the representative drugs are omeprazole, ranitidine, etc. The third category, protective agents of gastric mucosa, can be treated symptomatically with such drugs as bismuth potassium citrate tablets and bismuth citrate agent. It is usually a triple drug treatment at the same time, which can provide a better treatment effect.
