This week a study was published today in The New England Journal of Medicine. It showed that in a randomized controlled clinical trial, Vivitrol significantly prevented relapse to opioid dependence in men previously substance-dependent and involved with the criminal justice system. Here’s a link to the study. Full text is free.

Thank you for your comment regarding this new study publication. The results are encouraging: long-acting naltrexone was a more effective treatment option in this patient population when given in addition to the usual community counseling programs (21% lower relapse rate during the 6-month trial). It is also encouraging that there were fewer overdoses both during and after completion of the 6-month naltrexone treatment. Unfortunately, the benefit of relapse prevention in this naltrexone study group was only present during the 6 months of treatment with injections, as the rate of opioid use was similar in both groups at the 12-month and 18-month follow-ups.
