Buprenorphine maintenance: office-based treatment with addiction clinic support.
BACKGROUND
Buprenorphine has already been registered in 27 European countries for maintenance therapy in opioid-dependent patients. In our office-based prescription study we applied sublingual buprenorphine, initiating the treatment at the addiction clinic with subsequent treatment at the offices of general practitioners (GPs) to evaluate its efficacy and feasibility in two different treatment settings.


METHODS
Sixty opioid-dependent patients were studied for a period of 15 weeks. The first 3 weeks of treatment initiation took place at the addiction clinic, followed by 12 weeks of treatment by GPs. Mean outcome measures were retention rate and additional consumption of illicit substances in addition to the evaluation of whether buprenorphine can be prescribed successfully by GPs.


RESULTS
The retention rate was 57% (n = 34). No significant differences occurred between the treatment phases at the specialized addiction unit and the GPs' offices. During the 15-week period a significant improvement in well-being and a significant reduction in craving for heroin (p < 0.001) and cocaine (p < 0.001) could be calculated for patients stabilized on a mean dose of 16 mg buprenorphine. Furthermore a significant reduction in additional consumption of opioids (p < 0.001) was found.


CONCLUSIONS
Our results show the involvement of office-based prescription, which should further encourage colleagues to treat opioid-dependent subjects with buprenorphine to make more treatment options for this target group available.
