It has small to no in vivo affinity for the serotonin (5HT) or norepinephrine (NE) transporters. However, elevated concentrations of NE and 5HT while in the prefrontal cortex and hypothalamus have been observed adhering to modafinil administration, perhaps as an indirect result of elevated extracellular dopamine.
Stone et al (2002) showed that the α1A adrenergic receptor antagonist WB4101 and the α1D antagonist BMY7378 experienced tiny effect on the rise in motor activity brought on by modafinil, but terazosin, which blocks α1A, α1D, and α1B receptors significantly attenuated this outcome. On top of that, modafinil had quite compact results on gross movement in α1B receptor knockout mice.

Modafinil inhibits CYP2C19, and is a potent suppressor in hepatocytes of CYP2C9 (Robertson et al 2000), which itself hasn't nonetheless been discovered to be existing from the Mind, but other cytochrome P450 enzymes which include CYP2C enzymes are actually located in the brain, and there is proof for a role of brain CYP 2C9 specially (Llerena et al 2003; Gervasini et al 2004). This distinct member of your cytochrome P450 family has been revealed to generally be a functionally suitable source of reactive oxygen species in coronary artery ischemia and reperfusion injuries, and inhibition of cytochrome P450 enzymes is demonstrated to lessen harm in coronary artery ischemia and reperfusion (Fleming et al 2001; Granville et al 2004).
