Can we effectively manage binge eating disorder with pharmacotherapy?

Abstract

Introduction: Pharmacological and other treatments for binge eating disorder (BED) predate its inclusion as the third main eating disorder in the 2013 DSM-5. Currently, second in line to psychological therapy are psychotropics such as antidepressants, anticonvulsants and stimulants.

Areas covered: This review summarizes the evidence and emerging evidence on the pharmacotherapies for BED and their potential for wider use.

Expert opinion: Pharmacotherapy has utility as an alternative or adjunctive treatment for those exhibiting insufficient response to, or not preferencing, psychological interventions. Medications may also benefit individuals with BED and other co-occurring mental health conditions, such as depression and attention deficit hyperactivity disorder. In addition, there are several agents (e.g. glucagon like peptide-1 receptor agonists and the combination of naltrexone-bupropion) displaying promise for weight and binge eating reduction in people with BED and high BMI. Future research should extend the understanding of the role of medication in BED, focusing on their sustained effects over time, when and if they may be ceased, their effectiveness in people with adequate weight, and the risks associated with weight loss in those with BED and high weight.
