5. Study Description
Brief Summary
The primary objective of this study is to evaluate the relative efficacy of a centrally-acting analgesic (duloxetine) versus a peripherally acting analgesic (topical diclofenac) for pain and associated symptom management in knee osteoarthritis. Secondary objectives include the determination of which self-report and experimental pain measures best differentiate those who respond better to duloxetine than diclofenac.
Detailed Description
This is a randomized, blinded, crossover, controlled study design comparing duloxetine and topical diclofenac for osteoarthritis pain.
The study cohort will be individuals who have a confirmed diagnosis of knee osteoarthritis. Subjects will be randomized only after all entry criteria have been met. These individuals will be evaluated at baseline, and then followed longitudinally following enrollment.
