Brief summary: It is hypothesized that the use of aripiprazole (Abilify) in patients with alcohol and/or drug dependence with comorbid psychiatric conditions will lead to:

* Reduction in the amount of alcohol and/or drugs used as measured by the Time Line Follow Back (TLFB) and the Addiction Severity Index (ASI)
* Reduction in cravings for alcohol and drugs as measured by the Penn Alcohol Craving Scale
* Reduction in symptoms of co-morbid psychiatric disorders compared to before starting aripiprazole.

Detailed description: Substance abuse disorders are a major public health problem. With a current prevalence rate of 18%, substance abuse and dependence costs the nation over $300 billion per year in treatment costs and lost productivity. Approximately 20% of all patients attending primary care clinics and 35% of all patients attending psychiatric clinics meet Diagnostic and Statistical Manual IV (DSM IV) criteria for substance abuse or dependence.

The treatment of substance abuse and dependence disorders is complex and involves individual and group therapy, maintenance of sobriety, commitment to structured living, and participation in self-help groups. To date, pharmacotherapy for substance dependence disorders has had limited success. Several medications have been tested in the past, including tricyclic antidepressants, selective serotonin reuptake inhibitors, buspirone, bupropion, venlafaxine, nefazodone, bromocriptine, amantadine, naltrexone, and acamprosate. Of these, naltrexone has obtained an FDA indication for treatment of alcohol dependence, and acamprosate is in use in Europe. However, these medications are effective in only a relatively small proportion of patients. Benzodiazepines may be useful in treatment of withdrawal syndromes, but their potential for abuse and dependence limits their use in maintenance treatment.

This is an open label pilot study of aripiprazole therapy in the treatment of patients with substance use disorders and co-morbid disorders like Schizophrenia, Schizoaffective disorder, Bipolar disorder, Major depressive disorder, Anxiety (Panic disorder, Generalized Anxiety Disorder, Post-Traumatic Stress Disorder). While Aripiprazole has been approved for the treatment of Schizophrenia, its use in other psychiatric disorders is off label use. Increasing evidence suggests that Aripiprazole might offer some benefit for other psychiatric disorders besides Schizophrenia.
