  Purpose
The purpose of this study is to evaluate the acceptability and safety of switching to Suboxone® (buprenorphine plus naloxone) and the effect of the switch on medication dispensing. Subjects, for whom a therapy with Suboxone® is indicated and planned prior to study enrollment and who are willing to participate, will initiate therapy on Day 1 of the study. The dosage will be adjusted between Day 2 to 7 depending on patient's needs and determined by the treating physicians in accordance with the SmPC of Suboxone®. Data will be collected at baseline, day 1 til 7, the end of weeks 2 and 4 and monthly up to the end of Month 12.

Primary Outcome Measures:
  • Retention Rate [ Time Frame: month 6, month 12 ]
    The primary objective of this study was to determine the retention rate of patients after 6 and 12 months of treatment with buprenorphine/naloxone measured by the percentage of patients remaining in the study


Secondary Outcome Measures:
  • Dosing of Suboxone (Buprenorphine Plus Naloxone) [ Time Frame: day 1, month 6, month 12 ]
    One of the secondary objectives was to evaluate the effect of the switch to buprenorphine/naloxone on medication dispensing measured by dose.

  • Dispensing of Suboxone (Buprenorphine Plus Naloxone) [ Time Frame: month 6, month 12 ]
    Another of the secondary objectives was to evaluate the effect of the switch to Suboxone (buprenorphine plus naloxone) on medication dispensing measured by frequency of visits to the treating physician or pharmacy to receive the medication (daily, biweekly, once weekly, monthly, other)
