A Study of Rabeprazole for Prevention of Non Steroidal Anti-inflammatory Drug -Associated Gastroduodenal Injury
A Double-blind Randomized Placebo Controlled Trial of Rabeprazole for Prevention of NSAID-associated Dyspepsia and Gastroduodenal Injury
The aim of this study is to determine whether rabeprazole is superior to placebo in preventing dyspepsia and gastroduodenal injury in subjects with osteoarthritis (OA) and/or rheumatoid arthritis (RA) and/or bone pain.

Non steroidal anti-inflammatory drugs (NSAIDs) are well known to increase the risk of gastroduodenal (GD) ulcer and its complications. Up to 40% of average-risk NSAID users suffer from dyspepsia without endoscopic evidence of gastroduodenal injury. It results a significant loss of productivity and impairment of Quality of Life (QoL). Proton pump inhibitors (PPIs) have been shown to be effective in preventing and reducing NSAID-induced GD injury. PPIs are believed to have a class effect but Rabeprazole, the least expensive PPI, is grossly under-utilized in this area .

Current Hospital Authority (HA) guidelines, however, only endorse the use of PPI in patients at high risk of ulcer bleeding. Since NSAID-induced dyspepsia is not an indication for PPI according to HA guidelines, those patients do not receive PPI for treatment.

Exclusion Criteria:

  • History of gastrointestinal (GI) hemorrhage
  • History of gastric or duodenal surgery
  • Presence of erosive esophagitis, gastric-outlet obstruction
  • Likelihood of requiring treatment during the study with drugs not permitted by the protocol
  • Impaired hepatic function (SGPT (ALT) or serum glutamate oxaloacetate transaminase (SGOT) (AST) > 2 x upper limit of normal) or renal function (serum creatinine > 200 umol/l)
  • Any other condition or baseline finding which, in the investigator's judgment, might increase risk to the subject or decrease the chance of obtaining satisfactory data to achieve study objectives
  • Anemia with Hb < 10 g/dL

    • disease-modifying antirheumatic drug (DMARDs) (unless stable dose for ≥ 12 weeks)
    • Iron replacement therapy (a dose > 15mg elemental iron/day)
    • Iron replacement therapy (a dose > 15mg elemental iron/day) or supplements for deficiency prevention (a dose ≤ 15mg elemental iron/day) due to anemia or any other reason
    • Double anti-platelet therapy (e.g. aspirin + Plavix)
    • Anti-coagulants
    • Anti-ulcer medications, e.g. sucralfate, H2 receptor antagonists (H2RAs), misoprostol, PPIs other than study medications
    • Sucralfate, misoprostol or regular H2 receptor antagonists (H2RAs) (> 3 days/week)
