[NSAID ulcer (H. pylori, treatment, prevention)].

Although it has been reported that NSAID ulcer has been increasing in western countries, the epidemiology and treatment or prevention of this type of peptic ulcer have not been fully studied. Recently 'Guideline for the treatment of gastric ulcer' has been published in Japan. Based on the data described in the guideline, at present it is recommended to use misoprostol, protonpump inhibitor, or high dose of H2 receptor in the prevention of NSAID ulcer. In the treatment of NSAID ulcer, to stop NSAID and/or to use misoprostol or protonpump inhibitor are recommended.
