Atypical antipsychotics show promise for treating anorexia nervosa (AN) symptoms like depression and anxiety, but more research is needed to confirm their effectiveness, especially for weight gain.
Area of Science:
- Psychiatry
- Pharmacology
Background:
- Mixed opinions exist on the efficacy of atypical antipsychotics for anorexia nervosa (AN).
- A comprehensive literature review was conducted to address this uncertainty.
Purpose of the Study:
- To evaluate existing literature on the use of atypical antipsychotics in treating patients with AN.
Main Methods:
- A narrative synthesis of studies and clinical guidelines published before September 2009.
- Included randomized-controlled trials, open-label trials, and case reports.
Main Results:
- Forty-three publications were reviewed, focusing on olanzapine, quetiapine, and risperidone.
- Atypical antipsychotics appear safe and may improve depression, anxiety, and core eating disorder psychopathology.
- Evidence for weight gain enhancement is currently insufficient.
Conclusions:
- High-quality evidence is required to guide clinical practice.
- Recruiting sufficient numbers of AN patients for research trials remains a significant challenge.
