Detailed Description:

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.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Outpatient or inpatient subjects with a clinical diagnosis of OA or RA or any bone pain
  • Subjects expected to require regular anti-inflammatory therapy for arthritis symptom management
  • Subjects should have no history of peptic ulcer complications
  • Screening tests are negative for H pylori
  • Subjects who test positive can be re-screened after eradication of H. pylori

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
  • Suspected or clinical diagnosis of inflammatory bowel disease
  • Congestive heart failure (NYHA class III- IV)
  • Subjects considered to have a requirement for continued use of:

    • Corticosteroids (dose equivalent of prednisolone/ prednisone >10mg daily stable dose)
    • 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)
    • COX-2 inhibitors
    • anti-ulcer medications or COX-2 selective inhibitor at screening allowed if treatments discontinued at this time
