Summary

The aim of this project is to conduct a multi-site effectiveness study to determine whether the addition of a monthly injection of depot naltrexone to treatment as usual (TAU) will significantly improve outcome in parolees and probationers with a history of opioid addiction compared to TAU alone. Participants will be randomized to either treatment as usual in community programs or monthly injections of depot naltrexone for six months with treatment as usual in community programs. The effectiveness of depot naltrexone has never been studied in opioid dependent parolees. all parolee subjects will be evaluated at baseline, while in treatment, and at 6, 12 and 18 month post entry time points. The primary study outcomes are retention in treatment, drug use, re-arrests, psychosocial and medical/psychiatric functioning, and economic costs and benefit costs of naltrexone.

  • Have dx of opioid dependence according to DSM-IV criteria
  • be in good general health as determined by complete physical and laboratory tests;
  • Under some form of criminal justice supervision for at least 12 months;
  • Have a negative result for urinary opioids and no sign of opiate withdrawal after IV (or IM) injection of 0.8 mg of naloxone; and
  • Express a goal of opiate free treatment rather than agonist maintenance

Exclusion Criteria

  • Current drug or alcohol dependence that requires medical supervision;
  • untreated psychiatric disorders that might make participation hazardous (e.g. untreated psychosis, bipolar disorder with mania, significant suicide risk). Adequately treated psychiatric disorders and appropriate psychotropic medications would be allowed.

Adequately treated medical conditions are acceptable; 4. female subjects who are pregnant or lactating, or female subjects of childbearing potential who are not using birth control (oral contraceptives, barrier (diaphragm or condom) plus spermicide, or levonorgestriel implant); 5. Liver failure or liver function test levels greater than three times normal; 6. History of allergic reaction to naltrexone; 7. History of a drug overdose in the past 3 years; and 8. Current diagnosis of chronic pain disorder for which opioids are prescribed for pain relief.
