To investigate the safety and tolerability of the atypical antipsychotic quetiapine in anorexia nervosa patients, and to determine the effect of quetiapine treatment on anorexic psychopathology and other key outcome measures including weight and body image, we conducted a naturalistic, open-label, 12-week randomized controlled trial of low-dose (100-400 mg/day) quetiapine treatment versus treatment as usual in 33 anorexia nervosa patients from our Eating Disorder Clinics. To monitor the effects of treatment over the medium term, the participants were then followed up with assessment visits at 6 and 12 months after the end of the treatment phase. Low-dose quetiapine treatment resulted in both psychological and physical improvements, with minimal associated side-effects. Given the overall trend toward improvement that we observed, quetiapine appears to be a promising candidate for the treatment of anorexia nervosa. Further large-scale placebo-controlled clinical trials will be necessary to fully evaluate the benefits of quetiapine treatment for this disorder.
