Primary Outcome Measures:
  • To assess the efficacy of esomeprazole 40 mg qd versus placebo and esomeprazole 20 mg qd versus placebo for up to 6 months of the treatment for the prevention of gastric (and/or duodenal) ulcers in patients receiving daily NSAID therapy and being at risk [ Time Frame: Assessments at Week 0, Week 4, Week 12, Week 26 ]

Secondary Outcome Measures:
  • Investigator-assessed symptoms, defined as control of NSAID-associated GI symptoms for up to 6 months of treatment with esomeprazole 40 mg qd versus placebo and esomeprazole 20mg qd versus placebo in patients receiving daily NSAID therapy. [ Time Frame: Assessments at Week 0, Week 4, Week 12, Week 26 ]
  • Safety and tolerability of esomeprazole 40 mg qd versus placebo and esomeprazole 20mg qd versus placebo for up to 6 months of treatment in patients receiving daily NSAID therapy [ Time Frame: Assessments at Week 0, Week 4, Week 12, Week 26 ]
