Partial agonists are effective for stimulants, opiate, cocaine and nicotine dependence and dopami- ne D2 receptors have been implicated in the abuse related effects of substances. In addition, it has shown that aripiprazole reduced substance use in schizophrenic, bipolar or schizoaffective disor- der patients comorbid with substance use disorders, suggesting that aripiprazole would be useful in patients with substance use disorders and co-existing psychiatric conditions. Open-label eviden- ce is also available for use of aripiprazole in disruptive behavior disorders in children and adoles- cent. Therefore, aripiprazole might be an effective strategy for adolescent patients with inhalants use disorders and conduct disorder. In the reported cases, aripiprazole treatment successfully cont- rolled on psychiatric symptoms of adolescent patients and also reduced the frequency of substan- ce use in these patients.
