[Pharmacotherapy for the treatment of anxiety disorders in children and adolescents: a sistematic review].

Anxiety disorders are very prevalent in children and adolescents, causing serious impairments. The pharmacological treatment for these disorders is not much investigated in children and adolescents. Thus, there is no consensus about its indication. The present study aims to check the efficacy and tolerability of drugs used for the treatment of anxiety disorders in children and adolescents in the context of evidence based medicine. A systematic literature review was carried out in the main databases. In addition, authors were contacted. We found seven studies classified as A or B according to criteria established by the Cochrane Collaboration. Findings suggest efficacy for selective serotonin reuptake inhibitors, insignificant or unfavorable results for benzodiazepines and imipramine. Some studies present methodological problems. Methodological improvements are needed in futures clinical trials.
