Ferraro et al (2001) calculated tritiated serotonin efflux from modafinil in vitro on serontonergic synaptosomes and cortical slices and located that modafinil was unable to improve spontaneous 5-HT efflux or K+-evoked five-HT efflux in synaptosomes, but modafinil was able to extend electrically evoked 5-HT efflux in cortical slices, and this influence was enhanced by serotonin uptake blockade.
It is also valuable for persons whose Work demand them to become notify and Energetic in the evening when their circadian clocks are telling them to sleep.

In vivo reports demonstrate anatomically selective neurochemical consequences of modafinil on monoaminergic systems (de Saint Hilaire et al 2001; Ferraro et al 2002), and, notably, although modafinil boosts TMN fos expression (Scammell et al 2000) and HAergic tone it can be unable to exert this effect when administered straight in to the TMN (Ishizuka et al 2003).
