METHODS： Seventy-one consecutive patients on chronic therapy with NSAIDs were enrolled in the study and divided into groups A and 13 （group A receiving 40 mg pantoprazole daily, group B only receiving NSAIDs）. Sucrose test was performed at baseline and after 2, 4 and 12 wk, respectively. The symptoms in the upper gastrointestinal tract were recorded. RESULTS： The patients treated with pantoprazole had sucrose excretion under the limit during the entire follow-up period. The patients without gastroprotection had sucrose excretion above the limit after 2 wk, with an increasing trend in the following weeks （P = 0.000）. A number of patients in this group revealed a significantly altered gastric permeability although they were asymptomatic during the follow-up period. CONCLUSION： Sucrose test can be proposed as a valid tool for the clinical evaluation of NSAIDs-induced gastric damage in both acute and chronic therapy. This tecnique helps to identify patients with clinically silent gastric damages. Pantoprazole （40 mg daily） is effective and well tolerated in chronic NSAID users .展开更多

However, gastrointestinal(GI) toxicity associated with NSAIDs is an important medical and socioeconomic problem. Local generation of various reactive oxygen species plays a significant role in the formation of gastric ulceration associated with NSAIDs therapy. Co-medication of antioxidants along with NSAIDs has been found to be beneficial in the prevention of GI injury. This paper describes the synthesis and biological evaluation of N-1-(phenylsulfonyl)-2-methylamino-substituted-1H-benzimidazole derivatives as anti-inflammatory analgesic agents with lower GI toxicity. Studies in vitro and in vivo demonstrated that the antioxidant activity of the test compounds decreased GI toxicity.展开更多
