How useful are pharmacological treatments in eating disorders?
The eating disorders anorexia nervosa (AN) and bulimia nervosa (BN) are multifactorial syndromes of unknown origin which occur typically in female adolescents or young women. Nowadays, AN and BN are most often triggered by dietary restriction. Both are treatable conditions. As in other psychiatric disorders, a lower comorbidity, a shorter duration of illness, less familial psychopathology, and, in AN, a higher minimal weight have been shown to be associated with a better outcome. So far, no abnormalities specific to AN or BN that would shed light on their etiology have been identified. Controlled and uncontrolled studies testing antipsychotic, antidepressant, weight-promoting, and prokinetic drugs have demonstrated that the core symptoms of AN are refractory to currently available psychotropic medication. For relapse prevention, however, antidepressant medication may be useful. Renutrition, psychotherapy, and family therapy remain the cornerstones of treatment for AN. Placebo-controlled studies with antidepressant drugs have been far more promising for treating BN in the short term. Recent studies have found that lasting symptomatic improvement and remission require the addition of psychological treatments in the form of cognitive and interpersonal psychotherapy. The steady stream of newly identified peptides and other molecules involved in appetite and body weight control may ultimately provide cues to better targeted treatments of eating disorders.
