Condition non-steroidal anti-inflammatory drug adverse reaction
Treatments part1:teprenone, part1:eac-t, part1:ea-emc-t, part2:gga group
Sponsor Sun Yat-sen University
Start date June 2007

Trial size 369 participants
Trial identifier NCT01547559, 5010-2007005


We aim to evaluate the protective effects of eradication of HP and continue using Geranylgeranylacetone (GGA) on NSAIDs related gastroenterological lesions. We further aim to explore the effect of GGA on small-intestinal mucosal injuries induced by diclofenac sodium in patients with rheumatic diseases who didn't take NSAIDs in the preceding 6 months.

Additional Information

Official title Evaluation of Preventive and Treatment Effects of Hp Eradication and Teprenone in Patients Taking NSAIDs
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.On the other hand, Small-intestinal mucosal injuries induced by non-steroidal anti-inflammatory drugs (NSAIDs) are common. However, there are still no effective and reliable interventions established. Geranylgeranylacetone (GGA) is a mucosal protective agent, so we develop an additional trail to clarify the discrepancies of GGA effects on NSAIDs-induced small-intestinal mucosal injuries.
