A 2011 study for brief and extended use of buprenorphine followed by a taper-off period.
The success outcome tested by the study was “minimal or no opioid use based on urine test–confirmed self-reports.”
According to the abstract, the study did not include patients not given buprenorphine. The study found that even after 12-weeks on buprenorphine followed by an 8-week taper “the likelihood of an unsuccessful outcome is high.”
