Osteoarthritis of knee is common degenerative musculoskeletal diseases. Non-steroidal antiinflammatory drugs (NSAIDs) are used to decrease pain symptom but someone can not tolerate its gastrointestinal adverse effects. In vitro studies showed that curcumin had an inhibitory effect on substances playing an important role in inflammatory pathway. The mechanisms by which curcumin prevents inflammation are postulated through inhibition of many cytokines, for example, lipo-oxygenase, cyclo-oxygenase, and phospholipase. Therefore, if curcumin is effective as NSAIDs with less side effects, it can be an alternative treatment for those OA knee patients.

Arms Assigned Interventions
Experimental: curcuma domestica
1,500 mg/day (oral) divided into 3 times for 28 days
Drug: Curcuma domestica extracts
1,500 mg per day (oral)divided into 3 times for 28 days
Other Name: Curcumin
Active Comparator: Ibuprofen
1,200 mg/day (oral) divided into 3 times for 28 days
Drug: Ibuprofen
1,200 mg/days (oral) divided into 3 times for 28 days
Other Name: Brufen

Detailed Description:

Curcumin was demonstrated to be safe and had anti-inflammatory activity in six studies in humans. It may exert its anti-inflammatory activity by inhibition of a number of different molecules that play a role in inflammation.

Our experience in a study of 100 subjects revealed a trend towards a greater effect in OA patients receiving Curcuma domestica extracts. However, studies with adequate sample and dosage of Ibuprofen are recommended to demonstrate the efficacy of C.domestica extracts in alleviating knee pain and improving knee functions.

The objective of the study was to determine the efficacy and safety of C.domestica extracts in pain reduction and functional improvement in patients with knee osteoarthritis.
