  Purpose

We wish to compare the effect of long acting vs short acting opioids in chronic non-malignant pain. The study opioid is Dihydrocodeine Continus and Dihydrocodeine 30 mg tablets. We measure pain relief, health related quality of life, sleep, breakthrough pain and depression with validated questionnaires to compare the two treatment arms.

Hypothesis: The pain relief will be better and more stable with long acting opioids. Quality of sleep, breakthrough pain and quality of life will also be improved with long acting dihydrocodeine.

Secondary Outcome Measures:
  • sleep quality and duration [ Time Frame: 9 weeks ] [ Designated as safety issue: No ]
    Validated questionaires which have been properly translated to Norwegian will be used in the assessment of each outcome variable:Pain, Quality and duration of sleep, Quality of life, Depression, Moods and breakthrough pain will be measured.

  • quality of life [ Time Frame: 9 weeks ] [ Designated as safety issue: No ]
    Validated questionaires which have been properly translated to Norwegian will be used in the assessment of each outcome variable:Pain, Quality and duration of sleep, Quality of life, Depression, Moods and breakthrough pain will be measured.

  • Depression and moods [ Time Frame: 9 weeks ] [ Designated as safety issue: No ]
    Validated questionaires which have been properly translated to Norwegian will be used in the assessment of each outcome variable:Pain, Quality and duration of sleep, Quality of life, Depression, Moods and breakthrough pain will be measured
