Ziprasidone for Severe Conduct and Other Disruptive Behavior Disorders

• Status: Completed
• Trial end date: 2008-06-01
• Target enrollment: 0
• Participant gender: All

Summary

To investigate and compare the efficacy, safety and tolerability of ziprasidone versus placebo in the treatment of conduct disorder (CD), oppositional defiant disorder (ODD) and disruptive behavior disorder not otherwise specified (DBD-NOS) of older children and adolescents in an outpatient setting.

Conduct and other behavior disorders are some of the most common forms of psychopathology in children and adolescents. The main characteristic of these disorders is a repetitive and persistent pattern of antisocial, aggressive or defiant behavior that involves major violations of age-appropriate expectations or norms. According to the guidelines of the German Society for Child & Adolescent Psychiatry & Psychotherapy (Deutsche Gesellschaft für Kinder- und Jugendpsychiatrie und -psychotherapie DGKJPP), the European Society for Child and Adolescent Psychiatry (ESCAP), and the American Academy of Child and Adolescent Psychiatry (AACAP) currently no standard pharmacotherapy is established and recommended for children and adolescents. However Risperidone has been shown to be effective in the treatment of patients with disruptive behavior disorders and below average IQ.
