Jp. De Los Cobos et al., A controlled trial of daily versus thrice-weekly buprenorphine administration for the treatment of opioid dependence, DRUG AL DEP, 59(3), 2000, pp. 223-233
This study was aimed at determining whether thrice-weekly administration of
buprenorphine is as effective as daily administration for treating opioid
dependence. A total of 60 treatment-seeking opioid addicts were randomly as
signed to take buprenorphine tablets sublingually either every day (8 mg) o
r thrice-weekly (16 mg on Mondays and Wednesdays and 24 mg on Fridays) over
the course of a 12-week. double-blind, parallel trial. The buprenorphine d
osing schedule had no significant effect on treatment retention. The rates
of opioid-positive urine tests were significantly higher among those subjec
ts who were given buprenorphine thrice weekly (58.5%) than among those who
took it daily (46.6%). An analysis of the completers did not detect a signi
ficant effect of buprenorphine dosing schedule. The results obtained in our
clinical trials indicate the advisability of-daily doses of buprenorphine,
at least at the beginning of a maintenance programme. (C) 1999 Elsevier Sci
