Primary Outcome Measures:
  • The Percentage of Subjects Whose Gastric Ulcer(s) (GUs) Was (Were) Healed at Week 4 After Treatment With Esomeprazole 20 mg qd and Ranitidine 150 mg Bid in Patients Receiving Daily Non-steroidal Anti-inflammatory Drug (NSAID)Therapy. [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]

    Healed was defined as the absence of gastric ulcers. It was calculated as the proportion of subjects whose gastric ulcer(s) healed after 4 weeks treatment.

    (Ulcers were on S stage, stage 1 = Nonblanchable erythema of intact skin, stage 2 = Partial thickness skin loss involving epidermis, dermis, or both, stage 3 = Full thickness skin loss involving damage to or necrosis of subcutaneous tissue, stage 4 = Full thickness skin loss with extensive destruction, tissue necrosis, or damage to muscle, bone, or supporting structures or absent).



Secondary Outcome Measures:
  • The Percentage of Subjects Whose Gastric Ulcer(s) Was (Were) Healed at Week 8 After Treatment With Esomeprazole 20 mg qd and Ranitidine 150 mg Bid in Patients Receiving Daily NSAID Therapy. [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Healed was defined as the absence of gastric ulcers (Ulcers were on S stage or absent). It was calculated as the proportion of subjects whose gastric ulcer(s) healed after 8 weeks treatment.

  • The Resolution of Heartburn Symptoms at Week 4 and Week 8 After Treatment With Esomeprazole 20 mg qd and Ranitidine 150 mg Bid in Patients Receiving Daily NSAID Therapy. [ Time Frame: week 4 and week 8 ] [ Designated as safety issue: No ]
    Resolution rate of investigator-assessed GI symptoms, including heartburn, acid regurgitation, nausea, abdominal fullness and sleep disorder. It was calculated as the percentage of subjects whose heartburn symptoms were resolved at Week 8.

  • Percentage of Participants With the Occurance of Any Adverse Event. [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]
    Safety evaluation including vital signs, physical examination, ECG, adverse events and clinical laboratory evaluations during 8 weeks treatment.

  • The Percentage of Participants Whose Duodenal Ulcer(s) (DUs) Was (Were) Healed at Week 4 and Week 8 After Treatment With Esomeprazole 20 mg qd and Ranitidine 150 mg Bid in Patients Receiving Daily NSAID Therapy. [ Time Frame: 4 and 8 week ] [ Designated as safety issue: No ]
    Healed was defined as the absence of ulcers (Ulcers were on S stage or absent). It was calculated as the proportion of subjects whose duodenal ulcer healed after 4 and 8 weeks treatment.

  • The Percentage of Participants Whose GU(s) and DU(s) in Combination Were Healed at Week 4 and Week 8 After Treatment With Esomeprazole 20 mg qd and Ranitidine 150 mg Bid in Patients Receiving Daily NSAID Therapy [ Time Frame: 4 & 8 weeks ] [ Designated as safety issue: No ]
    Healed was defined as the absence of ulcers (Ulcers were on S stage or absent). It was calculated as the proportion of subjects whose gastric and duodenal ulcer healed after 4 and 8 weeks treatment.
