Case reports of olanzapine treatment of anorexia nervosa

Two females with severe anorexia nervosa were treated with olanzapine in open trials. Olanzapine was tried because it has caused weight gain in other patient groups. Both anorexic patients had a chronic illness and had failed multiple other treatments. Olanzapine administration was associated with weight gain and maintenance as well as reduced agitation and resistance to treatment. These case histories support further exploration of this class of drugs in anorexia nervosa.
