New research funded by the National Institute on Drug Abuse (NIDA) revealed that the relapse rates among criminal justice involved adults with a history of opioid dependence were lower for participants receiving extended-release naltrexone than for those receiving treatment as usual (brief counseling and referrals for community treatment programs). Administered as a monthly injection, naltrexone is an FDA-approved sustained-release, opioid antagonist for the prevention of relapse to opioid dependence.

This study is the first large randomized trial of extended-release naltrexone versus usual care conditions among criminal justice involved adults. The findings showed that 24 weeks (six monthly injections) of extended-release naltrexone resulted in a significantly lower opioid relapse rate (43 percent vs. 64 percent) among the two groups. Additionally, while there were no overdoses observed in the extended-release naltrexone group, there were seven in the usual care group, with three resulting in fatalities.
