Oxycodone/Naloxone (OXN) Combination in Moderate to Severe Non-malignant Pain

The main objective of the study is to observe the OXN treatment of patients with moderate to severe non-malignant pain in daily clinical practise with respect to pain relief and bowel function. Patients who have insufficient pain relief and/or unacceptable side effects with the previous analgesic treatment WHO step 1 or 2 and require around-the-clock opioid therapy can be included in the study.
