A strong interplay exists between sleep and dietary habits, and sleep disturbances have been repeatedly documented in individuals with eating disorders (EDs). The orexin system - implicated in sleep regulation, energy homeostasis, and food reward - may represent a mechanist link between sleep alterations and disordered eating behaviors. Daridorexant is a dual orexin receptor antagonist (DORA) recently approved for the treatment of insomnia, with demonstrated efficacy and tolerability. Owing to its action on orexin neurons, the compound represents an intriguing option for addressing both sleep-related and core symptoms of EDs. By inhibiting motor hyperactivity, daridorexant may reduce excessive physical exercise in individuals with anorexia nervosa (AN) restricting type. Additionally, the compound may exert anti-binge effects, suggesting broad applicability in binge ED, bulimia nervosa, and binge/purging AN. In this framework, daridorexant emerges as a promising therapeutic option, offering a multifaceted approach to improving circadian rhythms, energy balance, and overall quality of life in individuals with diverse ED subtypes.
