Lumiracoxib: the Evidence of Its Clinical Impact on the Treatment of Osteoarthritis

Introduction: The symptoms of osteoarthritis (OA) include joint pain, stiffness, and a reduced ability to perform normal daily activities, which result in decreased quality of life. There is currently no known cure or means of preventing the progression of joint damage due to OA. Therefore, treatment focuses on the control of symptoms, including the use of various agents [including nonselective and selective nonsteroidal antiinflammatory drugs (NSAIDs)] to provide pain relief and reduce inflammation. Lumiracoxib is a selective cyclooxygenase-2 (COX-2) inhibitor for the treatment of OA.

Aims: To review the evidence for the treatment of OA with lumiracoxib.

Evidence Review: There is evidence that lumiracoxib reduces the pain and stiffness associated with OA, and is as effective as nonselective NSAIDs, and the COX-2 inhibitor celecoxib. There is some evidence that lumiracoxib treatment results in a lower incidence of upper gastrointestinal (GI) ulcer complications compared with nonselective NSAIDs. However, evidence suggests that there is no GI benefit in patients receiving concomitant aspirin medication. With the exception of GI ulcers, the evidence indicates that lumiracoxib has a tolerability profile similar to nonselective NSAIDs: low risk of cardiovascular (CV) events and a low incidence of edema. Changes in liver function occur in some patients, largely at doses >100 mg. The cost effectiveness of lumiracoxib compared with nonselective NSAIDs remains to be determined.

Clinical Value: Lumiracoxib is an alternative treatment option for OA which provides effective pain relief without the GI complications associated with nonselective NSAIDs, and with a low risk of CV events. Lumiracoxib is contraindicated in patients with current, previous, or at risk of, hepatic impairment.
