Injectable Versus Oral Naltrexone Treatment of Alcohol Dependence In Serious Mental Illness (SMI)

The primary aim of this study is to determine the feasibility of long-acting injectable naltrexone administration in a clinical trial in patients with SMI who also have a diagnosis of alcohol dependence. Secondary aims include providing a preliminary assessment of the tolerability and safety of long-acting injectable naltrexone as compared with oral naltrexone in patients with SMI who also have a diagnosis of alcohol dependence. An additional aim is to provide a preliminary assessment of the efficacy of long-acting injectable naltrexone as compared with oral naltrexone in reducing alcohol use from baseline levels
