[44] Modafinil was screened at a large panel of receptors and transporters in an attempt to elucidate its pharmacology. This means it has an accepted medical use but may also cause physical or psychological dependence and may be abused. To determine potential pathways via which modafinil acts, we administered a range of doses of modafinil to rats, recorded sleep/wake activity, and studied the pattern of neuronal activation using Fos immunohistochemistry. These phenomenological differences between modafinil and amphetamines, however, do not exclude the possibility that modafinil’s wake-promoting action are catecholaminergic in nature.

Modafinil has been shown to enhance cognition significantly, both in healthy non-fatigued people[13] and in people experiencing sleep deprivation.[14], Studies indicate that modafinil can improve attention, executive functions, memory, and learning in healthy people, whether sleep-deprived or not.[15], Some studies suggest that modafinil’s effects may be most marked among low-performing subjects.[16], Clinical trials confirmed that modafinil improves mood in healthy subjects but may result in anxiety.[17], Many users report that modafinil also enhances focus, memory, motivation, and verbal fluency.[18], It has also been shown to improve mental function for people with conditions that impair attention processing, such as ADHD,[19] cognitive decline related to physical or neurological disorders,[20][21] or drug dependence.[22], Modafinil has been shown to improve sports and exercise performance, largely by significantly extending the time before feelings of exhaustion are experienced and reducing the perception of fatigue.[23], Modafinil was added to the World Anti-Doping Agency’s list of prohibited substances in 2004.[24]. Taking Provigil with warfarin (Coumadin, Jantoven) may make your body get rid of warfarin more slowly.

(Taurasi and another player, Monique Coker, tested at the same lab, were later cleared. Peak plasma concentrations of modafinil (mean 4.82 mg/L) were reached 2.3 hours after a single 200mg oral dose in healthy volunteers.
