Alcohol dependence
Brief summary
Naltrexone is an opioid antagonist with a high affinity for the mu opioid receptor. The efficacy of extended-release naltrexone (Vivitrol) as a treatment for alcohol dependence has been demonstrated in clinical trials, raising the prospect of integrating pharmacologic treatment for alcohol dependence into general medical care settings. However, the feasibility of implementing this United States Food and Drug Administration approved treatment in the front-line settings in which it is most needed has not been demonstrated. This is an open-label pilot feasibility study of implementing treatment with Vivitrol in primary care medical clinics in a safety net hospital system affiliated with an urban academic center.
Interventions
Three sequential monthly injections of extended release injectable naltrexone (Vivitrol), with option to extend participation for an additional 12 months.

Recruitment details
The study began July 2007. Community recruitment was performed from August 2007 to September 2008 in the primary care clinics of Bellevue Hospital and Gouverneur Diagnostic and Treatment Centers, two public hospital facilities in lower Manhattan. 116 persons contacted study staff regarding possible participation, and 76 were consented and screened.
Pre-assignment details
Four consented patients were ineligible due to elevated liver function tests (n = 2), opioid dependence (n =1), and an uncontrolled psychiatric condition (n = 1). Seventy two participants met eligibility criteria and consented to study involvement, sixty-five participants presented for the initial treatment visit.
Participants by arm
| Arm | Count |
|---|---|
| Extended Release Injectable Naltrexone This was a single arm trial, with no formal control group. The treatment administered was a single 380-mg extended-release naltrexone (Vivitrol)dose injected intramuscularly into the upper, outer gluteus,alternating sides monthly. Medication injection was performed by physicians per package insert guidelines. A final Month 4 visit assessed treatment outcomes and satisfaction. Patients interested in further extended-release naltrexone treatment at study end were referred to a related 12-month extended-release naltrexone extension study, and all patients were able to continue in primary care. | 65 |
