•Diagnosis of rheumatoid arthritis (RA) occurred at least 6 months prior to the prescreening visit and no earlier than 16 years of age.
•Approved nonstudy anti-rheumatic therapy (including: antimalarials, azathioprine, oral or injectable gold salts, leflunomide, methotrexate, sulfasalazine, oral corticosteroids, or a solubilized TNF antagonist or TNF receptor antagonist) has been at stable dosing for 1 month. Patient must not have discontinued such therapy within 1 month prior to the prescreening visit.
•Patient is willing to avoid excess alcohol for the duration of the study [i.e., will consume no more than 2 drinks (beer 8 oz, wine 4 oz, liquor 1 oz) per day].
•Excepting rheumatoid arthritis, patient is judged to be in otherwise general good health based on medical history, physical examination, and routine laboratory tests.
•In the opinion of the study nurse/coordinator and the investigator, the patient is willing and able to comply with the protocol.

Exclusion Criteria

Previous or Concurrent Diseases
a. Patient is mentally or legally incapacitated» has significant emotional problems at the time of the study, has a history of psychosis, or is unable to give informed consent.

Systemic lupus erythematosus, spondyloarthropathy, polymyalgia
rheumatica, psoriatic arthritis, ochronosis, pseudogout, or Pagets disease. Note: Patients with a history of gout are allowed to enroll in the study; however, additional NSAID therapy will not be allowed for treatment of exacerbations during the course of the study. Patients with rheumatoid arthritis and secondary Sjogrens disease or fibromyalgia are permitted to enter the study.
c. Patient has a history of esophageal, gastric, biliary, or small intestine surgery (except simple ciosure of a perforation greater than 3 months prior to the study). This includes any gastrointestinal surgery that causes clinical malabsorption.
d. Patients estimated creatinine clearance is less than 30 ml/min or serum creatinine is greater than 2.0 mg/dL.
e. Patient has angina or congesiive heart failure, with symptoms that occur at rest or minimal activity, or has a history of myocardial infarction, coronary angioplasty, or coronary arterial bypass grafting within the past 1 year.
f. Patient has uncontrolled hypertension [Note: Patients with medically controlled hypertension (diastolic blood pressure <95 mm Hg, systolic blood pressure <165 mm Hg) may participate.)
g. Patient has a history of stroke or transient ischemic attack within the past
2 years.
h. Patient has a history of hepatitis/hepatic disease that has been active within the previous 2 years.
i. Patient has a history of neoplastia disease and does not meet one of the exceptions listed below. If the patient has a history of leukemia, lymphoma, or myeloproliferative disease, then he/she is ineligible for the study regardless of the time since treatment, and in such cases, no exceptions will apply.
Exceptions
• Patient has adequately treated basal cell carcinoma or carcinoma in situ of the cervix or in a resected colonic polyp.
• Patient has other malignancies which have been successfully treated for over 5 years prior to screening, where in the judgment of both the investigator and treating physician, appropriate follow-up has revealed no evidence of recurrence from the time of treatment through the time of screening.
Patients who, in the joint opinion of the Merck Clinical Monitor and Investigator, are highly unlikely to sustain a recurrence during the duration of the study.
j. Patient has evidence of occult GI bleeding as documented by any one of three stool Hemocult screens obtained and read prior to allocation.
k. Patient has a history of any illness that, in the opinion of the investigator, might confound the results of the study, pose additional risk to the patient, or contraindicate treatment with an NSAID such as naproxen. If there is any question, the Merck Clinical Monitor will be consulted.
1. Patient has a history of inflammatory bowel disease.
m. A gastric, esophageal, and/or duodenal ulcer is present at initial endoscopy, or the patient has endoscopically evident pyloric obstruction or erosive esophagitis.
