Detailed Description:

NSAIDs are mainly used drugs in rheumatic disease and cardiologic disease. However the gastroenterological lesions prevent patients get benefits from continuing taking NSAIDs. HP is another important factor that increase gastroenterological lesions. Both HP and NSAIDs increase risk of peptic ulcers, however, no exact relation between these two factors has been found. It is important to evaluate the protective effects of eradication of HP in NSAIDs-taking patients. In many countries ,PPI is recommended as maintain treatment in NSAIDs-taking patients to prevent gastroenterological lesions. A multicenter, open-label, randomized, parallel-group study is needed to prove the effects of Teprenone as a replacer of PPI in maintain treatment.
