The purpose

Long-term use of opioids for chronic pain is a growing health and social problem, mainly because of the risk of dependence. Buprenorphine/naloxone is used as substitution therapy for opioid dependence. This substitution therapy in patients with opioid dependence lessens withdrawal symptoms and craving. There is limited research on the effectiveness of buprenorphine/naloxone in patients with chronic pain and iatrogenic opioid dependence. The primary aim of this study is to investigate the effectiveness of buprenorphine/naloxone in patients suffering from chronic pain and an iatrogenic induced dependence on opioids. This study will investigate the effects of opioid substitution by buprenorphine/naloxone in patients suffering from chronic pain using long-term opioids, with pain and withdrawal symptoms as primary outcome measures. Secondary outcome measures will be craving, substance use, psychiatric comorbidity and quality of life.
