The use of both cognitive behavioral therapy (CBT) and methylphenidate were linked with reduced binge eating and body mass index in patients with binge eating disorder, according to results from a study published in Psychiatry Research.

Researchers conducted a randomized study of 49 female patients with binge eating disorder. Study participants were randomly assigned to receive either CBT (n=27) or methylphenidate (n=22) for a total of 12 weeks. Psychostimulant therapy was started at 18 mg daily and titrated to a maximum of 72 mg daily, based on tolerance. The primary outcome was the number of objective binge episodes assessed weekly using a daily binge diary.

After analysis, the researchers found that both treatment strategies were associated with a significantly lower number of subjective (P <.001) and objective (P <.001) binge episodes. In addition, the investigators reported that methylphenidate was linked with a greater degree of weight loss vs CBT (4.4% vs 0.0%; P <.01).

One key limitation of the study was the self-reported nature of outcomes.

“Results provide preliminary support for the therapeutic benefit of methylphenidate in [binge eating disorder] treatment, and prognostic utility of impulsivity in this context,” the researchers wrote.

“Future investigations incorporating both men and women will be important to replicate and extend these results,” they concluded.
