As of 2006, modafinil had been tested in one small (N=34) double-blind randomized controlled trial for this use. [58] Modafinil has been found to directly inhibit the firing of midbrain dopaminergic neurons in the ventral tegmental area and substantia nigra of rats via activation of D2 receptors. [94] The first and only modafinil products was approved in November 2017,[95] but its marketing status in mainland China is still unknown. [50], Modafinil has been described as an "atypical" DAT inhibitor, and shows a profile of effects that is very different from those of other dopaminergic stimulants. Canada - Schedule F, therefore not an actively controlled drug; however a recent warning from Health Canada means that there has been an increase in seizures by the Border Services Agency, as well as a reduction in prescriptions from doctors. Modafinil reduces extreme sleepiness due to narcolepsy and other sleep disorders, such as periods of stopped breathing during sleep (obstructive sleep apnea). Russia – Schedule 2 controlled substance; can only be possessed if you have a … [1][29], Large-scale clinical studies have found no evidence of tolerance with modafinil at therapeutic dosages even with prolonged use (for 40 weeks and as long as three years). Modafinil is "available to crew to optimize performance while fatigued" and helps with the disruptions in circadian rhythms and with the reduced quality of sleep astronauts experience. VA Class: CN809 Modafinil, sold under the brand name Provigil among others, is a medication to treat sleepiness due to narcolepsy, shift work sleep disorder, or obstructive sleep apnea. Clin Pharmacol Ther.

"[128], A 2015 review of clinical studies of possible nootropic effects in healthy people found: "... whilst most studies employing basic testing paradigms show that modafinil intake enhances executive function, only half show improvements in attention and learning and memory, and a few even report impairments in divergent creative thinking. Neuroreport. ", In Sweden, modafinil is classified as a schedule IV substance and possession is therefore illegal without prescription.[104]. Biol Psychiatry.

magnitude of decreases in modafinil trough concentrations and inconsistency of occurrence suggest clinical importance is minimal.1, Potent inducers or inhibitors of CYP3A4: Potential pharmacokinetic interaction (altered elimination of modafinil).1, Substrates of CYP1A2, CYP2B6, and CYP3A4: Potential pharmacokinetic interaction (decreased plasma substrate concentrations).1 Caution if used concomitantly.1, Substrates of CYP2C19: Potential pharmacokinetic interaction (possible prolonged elimination of substrate).1, Substrates of CYP2C9: Potential metabolic interaction.1, Potential for interactions with highly protein-bound drugs considered unlikely.55, Possible increased SSRI concentration in patients who are CYP2D6 deficient1, Dosage adjustment of SSRI may be necessary1, Possible increased concentration of certain tricyclic antidepressants (e.g., clomipramine, desipramine) in patients who are CYP2D6 deficient1, Dosage reduction of tricyclic antidepressant may be necessary1, Antifungals, azoles (itraconazole, ketoconazole), Possible increased plasma modafinil concentrations1, Possible decreased modafinil plasma concentrations1, Pharmacokinetic interaction unlikely; however, increased concentrations of clomipramine and its active desmethyl metabolite reported in a patient who was a poor CYP2D6 metabolizer21 55, Dosage reduction of clomipramine may be necessary55, Possible elevation in serum clozapine concentrations and resulting clozapine toxicity53, Use concomitantly with caution; closely monitor serum clozapine concentrations53, Possible decreased blood concentrations and effectiveness of cyclosporine1 54, Consider monitoring cyclosporine concentrations; adjust cyclosporine dosage if necessary55, Clinically important pharmacokinetic interaction unlikely, although modafinil absorption may be delayed by approximately 1 hour1 25, Possible increased plasma diazepam concentrations1, May need to reduce diazepam dosage and monitor for toxicity1, Potential for decreased plasma concentrations of ethinyl estradiol; possible hormonal contraceptive failure1 45, Alternative or concomitant nonhormonal methods of contraception recommended during and for 1 month after discontinuance of modafinil therapy1, Interaction studies not performed to date55, Acute chorea, confusion, and hyperthermia (possibly related to serotonin syndrome) reported with concurrent modafinil and tranylcypromine56, Clinically important pharmacokinetic interaction unlikely, although modafinil absorption may be delayed by approximately 1 hour1 20, Possible decreased plasma modafinil concentrations1, Possible increased plasma phenytoin concentrations1, May need to reduce phenytoin dosage and monitor for toxicity1, Possible increased plasma propranolol concentrations1, May need to reduce propranolol dosage and monitor for toxicity1, Potential for reduced plasma concentrations and effectiveness of triazolam 1 45 54, Dosage adjustment of triazolam may be necessary1, Single-dose pharmacokinetics of warfarin not substantially affected by chronic administration of modafinil1, Monitor PT and/or INR more frequently1 43, Rapidly absorbed from the GI tract after oral administration, with peak plasma concentrations attained within 2–4 hours.1 b Absolute oral bioavailability not determined due to low aqueous solubility.1 b, Food may delay GI absorption by approximately 1 hour, but does not affect extent of absorption.1, Not known whether modafinil or its metabolites are distributed into milk.55, Metabolized to inactive metabolites via hydrolytic deamidation, S-oxidation, aromatic ring hydroxylation, and glucuronide conjugation.1 b, Excreted in urine (80%) and in feces (1%), mainly as metabolites.1, Approximately 10–15 hours after multiple dosing.1 b, In patients with severe hepatic impairment and cirrhosis (Child-Pugh class B, B+, C, or C+), clearance of modafinil is decreased by about 60% and steady-state concentrations are doubled compared with healthy individuals.1, In patients with severe chronic renal impairment (Clcr ≤20 mL/minute), pharmacokinetics of modafinil are not substantially altered, but exposure to modafinil acid (an inactive metabolite) is increased ninefold compared with healthy individuals.1, In geriatric patients, clearance of modafinil and metabolites may be reduced.1, Modafinil, a nonamphetamine wakefulness-promoting agent, is a 50:50 racemic mixture of the R- and S-enantiomers; exhibits pharmacologic properties similar to those of armodafinil.54 55, Promotes vigilance and wakefulness.1 2 3 4 6 8 10 26 27 28 30 32 34 37 38 39 40 41 42 44 Exact mechanism of action unknown,1 but may alter metabolic activity and increase neuronal activity in areas of the brain that control sleep/wakefulness and the biologic clock.1 9 10 11 16, Inhibits release of GABA2 4 5 6 14 and increases release of glutamate from the cerebral cortex,12 hippocampus,10 12 nucleus accumbens,6 12 medial preoptic area,5 6 12 and posterior hypothalamus in animals.5 12, Does not appear to act as a direct- or indirect-acting dopamine-receptor or α1-adrenergic agonist1 2 10 13 16 or as a sympathomimetic agent; 1 may stimulate central α1-adrenergic activity8 15 32 33 but has no important peripheral adrenergic activity.1 2 8 32 Blocked dopamine transporters and increased dopamine concentrations in the human brain (including the nucleus accumbens); drugs with such activity generally have abuse potential.57, At usual pharmacologic concentrations, does not bind to certain receptors that regulate sleep and wakefulness (e.g., norepinephrine, serotonin, dopamine, GABA, adenosine, histamine H3, melatonin, benzodiazepine).1, Does not inhibit MAO-B or phosphodiesterases 2-5; does not alter plasma melatonin or cortisol hormone profiles.7 55, Reinforcing properties in animals; produces psychoactive, euphoric, and subjective effects typical of classic CNS stimulants (e.g., amphetamines, methylphenidate) in humans.35 55, Importance of providing copy of written patient information (medication guide) each time modafinil is dispensed; importance of reading this information prior to taking modafinil.55, Importance of advising clinician of existing or contemplated therapy, including prescription and OTC drugs and/or herbal supplements, as well as any concomitant illnesses.55 Advise patient that it is prudent to avoid alcohol since combined use has not been studied.55, Potential increased risk of pregnancy in women taking hormonal contraceptives (e.g., oral contraceptives, injectable or implantable contraceptives, transdermal systems, vaginal rings, intrauterine devices) during and for 1 month after discontinuing modafinil therapy;
