Which medication is used to treat binge eating disorder?

Lisdexamfetamine is recognized as an effective treatment for binge eating disorder. It is a stimulant medication that works by affecting neurotransmitters in the brain, primarily dopamine and norepinephrine. This modulation can help manage the impulsivity and hyperactivity often associated with binge eating.

Research has shown that lisdexamfetamine can reduce the frequency of binge-eating episodes and improve any associated psychological distress. It is particularly beneficial because it not only addresses the behavior of binge eating but also has the potential to enhance overall mood and cognitive function, which can be impacted by disordered eating.

In contrast, the other medications listed are not typically first-line treatments for binge eating disorder. Zonisamide, while sometimes considered for weight management, is not specifically indicated for binge eating. Olanzapine, an antipsychotic, may lead to weight gain and might not be effective in targeting the specific impulses associated with binge eating. Naltrexone is primarily used to treat alcohol and opioid dependence and is not a standard treatment for this eating disorder, even though some studies have explored its use for weight management.

Understanding the specific pharmacological actions and indications of each medication reinforces the knowledge about effective treatment strategies for binge eating disorder, making lisdexamfetamine
