In this examine, the in vitro potency of modafinil in binding DAT and Web was minimal relative to methylphenidate, buproprion, or benztropine; having said that, modafinil showed DAT occupancy by PET that was akin to methylphenidate at clinically applicable doses. Furthermore, the doses utilized to detect DAT binding were 2–eight times reduce than that which promotes wakefulness in monkeys (Hermant et al, 1991). Also, whereas modafinil ten μg did not exhibit direct binding into the trace amine receptor one (TA1) in vitro, it did augment the stimulation of TA1 by phenylethylamine in cells expressing DAT and NET.
