Summary
Brief summary
Background: Osteoarthritis (OA) is a common, painful and disabling condition. Venlafaxine, a centrally acting antidepressant, has demonstrated analgesic effects in other chronic pain conditions. Primary aim: To determine the effectiveness, safety and tolerability of venlafaxine (75-150mg daily) compared to placebo in reducing pain in knee OA patients using a randomised, placebo-controlled double-blind design over 12-week. Primary hypothesis: Compared with placebo, in knee OA pain patients, 12-week treatment with venlafaxine will lead to a 10mm reduction in pain (assessed by 100mm visual analogue scale (VAS)). Significance and Innovation: Positive results will have a substantial and immediate impact on OA pain management. It will provide compelling evidence that venlafaxine can reduce pain in OA patients. Such findings can be easily translatable into clinical practice, as venlafaxine is low cost, well tolerated and currently available in Australia.
