Detailed Description:

An initial screening visit was performed in order to assess subject medical history and the potential eligibility of subjects. Following the initial screening visit, all potential subjects underwent a washout period from their usual arthritis medication and returned to the study center for a baseline visit to verify their eligibility.

At the completion of the baseline visit, all eligible subjects were randomly assigned to a treatment group and instructed on the dosing regimen for their assigned study medication.

Subjects returned to the study center for follow-up visits after Week 1 and Week 2 of treatment and a final visit after Week 4 of treatment or upon discontinuation from the study.

Eligibility

Ages Eligible for Study:	40 Years and older

Criteria

Inclusion Criteria:

Symptomatic idiopathic osteoarthritis of the knee for a minimum of six months duration requiring treatment with either an analgesic or anti-inflammatory agent on a regular basis (greater than or equal to three days/week) for at least three months.
A history of osteoarthritis of the knee characterized by pain of at least a moderate intensity.
Demonstrated radiographic evidence of mild to moderate osteoarthritis based on the Kellgren and Lawrence radiographic entry criteria of grade 2 or 3 osteoarthritis.
Subjects' physical ability was to be either American College of Rheumatology (ACR) Function Class I or II
At the baseline visit, subjects must have reported a maximum pain intensity experienced over the previous 24 hours of at least moderate on a five-point scale of none(0), mild(1), moderate(2), moderately severe(3), or severe(4) in order to be enrolled in the study.

Exclusion Criteria:
