A Preliminary Investigation of Outcome Following Gradual or Rapid Buprenorphine Detoxification

Eight opioid-dependent individuals were maintained on daily sublingual buprenorphine (8 mg) for 28 days and assigned randomly to one of two outpatient detoxification schedules under double-blind, double-dummy conditions. The two detoxification schedules were buprenorphine gradual (36 days; N = 3) or buprenorphine rapid (12 days; N = 5). Outcome variables were subject- and observer-ratings of opioid withdrawal, treatment retention and illicit-opioid use. Outcome measures were similar for the two groups during buprenorphine maintenance. Increases in subject-rated opioid withdrawal and illicit-opioid use, and a drop in treatment retention occurred during rapid detoxification. Stable subject-rated opioid withdrawal and treatment retention, and less illicit-opioid use occurred during gradual detoxification. These data suggest that gradual reduction in buprenorphine dose is likely to produce superior treatment outcomes than more rapid buprenorphine detoxification.
