Higher concentrations of one of the circulating metabolites, modafinil sulfone, are current in kids and adolescents as compared to adults. In non-clinical models, modafinil has weak to negligible interactions with receptors involved in the regulation of sleep/wake states (e.g., adenosine, benzodiazepine, dopamine, GABA, histamine, melatonin, norepinephrine, orexin, and serotonin).
