Eating disorders in children and adolescents: pharmacological therapies.

Anorexia nervosa and bulimia nervosa do exist in childhood, frequently have their onset in adolescence, and can result in serious medical and psychiatric sequelae that impede physical, emotional, and behavioral development. Although we use the same Diagnostic and Statistical Manual of Mental Disorders-Version 4 [DSM-IV] definitions to diagnose eating disorders in children, adolescents, and adults, these disorders may be expressed somewhat differently in younger populations, requiring assessment and treatment procedures that are tailored to their developmental needs. Significant advances have been made in recent years in our understanding of treatments for eating disorders in adults, and specifically pharmacological treatments for these disorders. Multiple double-blind, placebo-controlled studies have documented the short-term efficacy of antidepressant medications in bulimia nervosa. While the usefulness of pharmacological treatments for the acute treatment of anorexia nervosa is less clear, recent evidence suggests a role for medication in the relapse-prevention stage of the illness. The majority of the medication trials for the eating disorders have been conducted with adults, and the literature on the pharmacological treatment of children and adolescents with these disorders is very limited. This review article summarizes the current literature on the role of medication in the treatment of anorexia nervosa and bulimia nervosa, with particular emphasis on studies conducted in child and adolescent populations.
