Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • The proportion of patients with no gastric ulcers after 8 weeks of treatment. [ Time Frame: Esophagogastroduodenscopy (EGD) assessments at baseline, week 4, week 8, and efficacy evaluations at each visit including endoscopic evaluation for the presence of ulcers and erosions. ]

Secondary Outcome Measures:
  • The patient and investigator symptoms, defined as control of NSAID-associated GI symptoms up to 8 weeks of treatment with esomeprazole 40 mg vs ranitidine 150 mg bid and esomeprazole 20 mg qd versus ranitidine 150 mg bid in patients receiving daily N [ Time Frame: Assessments at Week 0, Week 4 and Week 8 ]
  • To look at any side effects of esomeprazole 40 mg vs ranitidine 150 mg bid and esomeprazole 20 mg qd versus ranitidine 150 mg bid in patients receiving daily NSAID therapy. [ Time Frame: Assessments at Week 0, Week 4 and Week 8 ]
