The study is designed to compare the risk of cardiovascular events (heart attacks, strokes) in patients receiving either etoricoxib or diclofenac. It will also compare the gastrointestinal tolerability of the two medicines. The study will be conducted in patients with either rheumatoid or osteo-arthritis.

Primary Outcome Measures:
  • Incidence of Confirmed Thrombotic Cardiovascular Serious Adverse Experiences based on combined data from this trial and MK0663 Protocols 061 & 072 (GI Tolerability in OA Patients and GI Tolerability Study in RA Patients ), respectively.

Secondary Outcome Measures:
  • Incidence of Confirmed Thrombotic Cardiovascular Serious Adverse Experiences from this trial alone. Gastrointestinal tolerability based on the percentage of patients that discontinue for clinical or laboratory gastrointestinal adverse experiences.
