Interventions

The main therapy will be supplied in tablets packed in blisters. Patients will either take a placebo, or MK-0663 120 mg once a day, or naproxen 500 mg twice a day, in a double-blind, placebo-controlled, double-dummy modality. Each morning, for 12 weeks, patients will take 3 tablets of the corresponding blister by mouth and 1 tablet each afternoon. Group name:Placebo Type of group

Primary

MeasureTime frame
Outcome name:Cumulative incidence of gastric and / or duodenal ulcers> 3 mm, either in the stomach or in the duodenum. An ulcer will be defined as a circumscribed rupture of the mucosa,> 3 mm in its greatest dimension (length), as measured by the close application of an open endoscopic biopsy forceps. The injury must also demonstrate an unequivocal depth. Measure:Accumulated incidence of gastric and / or duodenal ulcers Timepoints:At 12 weeks of treatment
