Practice parameter for the assessment and treatment of children and adolescents with attention-deficit/hyperactivity disorder. Treatment for hypersomnia includes medication, CPAP machines, and lifestyle changes.When sleepiness interferes with daily routines and activities, or reduces the ability to function, it is called "problem sleepiness." Symptomatic treatment of narcolepsy to improve wakefulness in adults with excessive daytime sleepiness.Careful attention to diagnosis and treatment of the sleep disorder is essential.Symptomatic treatment (in combination with standard treatment[s] for underlying obstruction) of OSAHS to improve wakefulness in adults with excessive sleepiness.If continuous positive airway pressure (CPAP) is the treatment of choice for a patient, make every effort to optimize treatment with CPAP for an adequate period prior to initiating modafinil.Careful attention to diagnosis and treatment of the sleep disorder is essential.Symptomatic treatment of SWSD to improve wakefulness in adults with excessive sleepiness.Careful attention to diagnosis and treatment of the sleep disorder is essential.Administer orally once daily without regard to meals.In patients with narcolepsy or OSAHS, usually administer as a single dose in the morning.In patients with narcolepsy, modafinil also has been administered in 2 divided doses daily, in the morning and at noonDosages up to 400 mg daily have been well tolerated, but may not provide additional clinical benefit beyond 200-mg daily dosage.Long-term efficacy (>9 weeks) not systematically established.Dosages up to 400 mg daily have been well tolerated, but may not provide additional clinical benefit beyond 200-mg daily dosage.Long-term efficacy (>12 weeks) not systematically established.Dosages up to 400 mg daily have been well tolerated, but may not provide additional clinical benefit beyond 200-mg daily dosage.Long-term efficacy (>12 weeks) not systematically established.Reduce dosage to 100 mg daily in patients with severe hepatic impairment (with or without cirrhosis).Current information inadequate to make specific dosage recommendations in patients with severe renal impairment.Consider use of lower than usual recommended dosage.Known hypersensitivity to modafinil, armodafinil, or any ingredient in the formulation.Serious skin rash (e.g., Stevens-Johnson syndrome [SJS]) requiring hospitalization and drug discontinuance reported in adult and pediatric patients receiving modafinil.Severe rash (e.g., possible SJS, multiorgan hypersensitivity reaction), sometimes associated with fever and other abnormalities (e.g., vomiting, leukopenia), reported in pediatric clinical trials.No known risk factors predict the occurrence or severity of rash.Benign rashes also occur with modafinil; not possible to predict which rashes will become serious.In patients with abnormal levels of sleepiness, level of wakefulness may improve with modafinil therapy, but may not return to normal.Frequently reassess degree of sleepiness, and, if appropriate, advise patients to avoid driving or other potentially dangerous activity.Adverse psychiatric effects (e.g., mania, delusions, hallucinations, suicidal ideation, aggression), sometimes resulting in hospitalization, reported in modafinil-treated patients;In controlled clinical trials, psychiatric symptoms that required treatment discontinuance in ≥0.3% of patients and more often for modafinil than for placebo included anxiety, nervousness, insomnia, confusion, agitation, and depression.Use with caution in patients with a history of psychosis, depression, or mania.Some clinicians recommend careful monitoring of patients receiving modafinil or other CNS stimulants for possible psychiatric effects.Angioedema and hypersensitivity (with rash, dysphagia, and bronchospasm) reported with armodafinil.Immediately discontinue therapy if any signs or symptoms of angioedema or anaphylaxis (e.g., swelling of face, eyes, lips, tongue, or larynx; difficulty swallowing or breathing; hoarseness) develop.Multiorgan hypersensitivity reactions, including at least 1 fatality, reported with modafinil.Reactions detected a median of 13 days (range: 4–33 days) after initiation of modafinil.No risk factors known to predict occurrence or severity.If a multi-organ hypersensitivity reaction is suspected, discontinue therapy.Use only in patients who have had a complete evaluation (e.g., complete history, physical examination, testing in a laboratory setting [polysomnography]) of excessive sleepiness and in whom a diagnosis of narcolepsy, OSAHS, and/or SWSD has been made in accordance with International Classification of Sleep Disorders (ICSD) or DSM diagnostic criteria.Consider that >1 sleep disorder may contribute to excessive sleepiness in some patients (e.g., OSAHS and SWSD concurrently in the same patient).Although modafinil has not been shown to cause functional impairment, altered judgment, thinking, or motor skills is possible with any drug affecting the CNS.In OSAHS, modafinil is indicated as an adjunct to standard treatment(s) for the underlying obstruction.Adverse cardiovascular effects (e.g., chest pain, palpitations, dyspnea, transient ischemic T-wave changes on ECG) reported in several modafinil-treated patients in association with mitral valve prolapse or left ventricular hypertrophy.Not recommended in patients with history of left ventricular hypertrophy or in patients with mitral valve prolapse who have experienced mitral valve prolapse syndrome (e.g., ischemic ECG changes, chest pain, arrhythmia) with previous CNS stimulant use.Use with caution in patients with recent history of MI or unstable angina.A greater proportion of modafinil-treated patients required new or increased use of antihypertensive medication compared with those receiving placebo in a retrospective analysis (2.4 and 0.7%, respectively).Modafinil is subject to control as a schedule IV (C-IV) drug.Produces psychoactive and euphoric effects, and alterations in mood, perception, thinking, and feelings similar to those observed with other CNS stimulants (e.g., amphetamines, methylphenidate), but current evidence indicates risk of abuse or misuse is lower with modafinil than with schedule II CNS stimulants (e.g., amphetamine, methylphenidate).Monitor patients closely during treatment for possible signs of misuse or abuse (e.g., incrementation of doses, drug-seeking behavior), particularly in those with history of drug or stimulant abuse (e.g., amphetamine, cocaine, methylphenidate).Possible reduced efficacy of hormonal contraceptives during and for 1 month after discontinuance of therapy.Possible reduced blood cyclosporine concentrations when given concurrently with modafinil.Not known whether modafinil or its metabolites are distributed into milk.Modafinil is not approved for use in pediatric patients for Serious skin rashes (e.g., erythema multiforme, Stevens-Johnson syndrome) associated with use of modafinil in pediatric patients.Limited experience indicates that the incidence of adverse effects in patients >65 years of age is similar to that in younger patients.Elimination of modafinil and its metabolites may be reduced; consider reduced dosage.Reduce dosage in patients with severe hepatic impairment.Use with caution in patients with severe renal impairment.Possible auto-induction of modafinil metabolism after multiple weeks of dosing; magnitude of decreases in modafinil trough concentrations and inconsistency of occurrence suggest clinical importance is minimal.Potent inducers or inhibitors of CYP3A4: Potential pharmacokinetic interaction (altered elimination of modafinil).Substrates of CYP1A2, CYP2B6, and CYP3A4: Potential pharmacokinetic interaction (decreased plasma substrate concentrations).Substrates of CYP2C19: Potential pharmacokinetic interaction (possible prolonged elimination of substrate).Substrates of CYP2C9: Potential metabolic interaction.Potential for interactions with highly protein-bound drugs considered unlikely.Possible increased SSRI concentration in patients who are CYP2D6 deficientPossible increased concentration of certain tricyclic antidepressants (e.g., clomipramine, desipramine) in patients who are CYP2D6 deficientDosage reduction of tricyclic antidepressant may be necessaryPharmacokinetic interaction unlikely; however, increased concentrations of clomipramine and its active desmethyl metabolite reported in a patient who was a poor CYP2D6 metabolizerPossible elevation in serum clozapine concentrations and resulting clozapine toxicityUse concomitantly with caution; closely monitor serum clozapine concentrationsPossible decreased blood concentrations and effectiveness of cyclosporineConsider monitoring cyclosporine concentrations; adjust cyclosporine dosage if necessaryClinically important pharmacokinetic interaction unlikely, although modafinil absorption may be delayed by approximately 1 hourMay need to reduce diazepam dosage and monitor for toxicityPotential for decreased plasma concentrations of ethinyl estradiol; possible hormonal contraceptive failureAlternative or concomitant nonhormonal methods of contraception recommended during and for 1 month after discontinuance of modafinil therapyAcute chorea, confusion, and hyperthermia (possibly related to serotonin syndrome) reported with concurrent modafinil and tranylcypromineClinically important pharmacokinetic interaction unlikely, although modafinil absorption may be delayed by approximately 1 hourMay need to reduce phenytoin dosage and monitor for toxicityPossible increased plasma propranolol concentrationsMay need to reduce propranolol dosage and monitor for toxicityPotential for reduced plasma concentrations and effectiveness of triazolam Single-dose pharmacokinetics of warfarin not substantially affected by chronic administration of modafinilRapidly absorbed from the GI tract after oral administration, with peak plasma concentrations attained within 2–4 hours.Food may delay GI absorption by approximately 1 hour, but does not affect extent of absorption.Not known whether modafinil or its metabolites are distributed into milk.Metabolized to inactive metabolites via hydrolytic deamidation, Excreted in urine (80%) and in feces (1%), mainly as metabolites.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.In patients with severe chronic renal impairment (ClIn geriatric patients, clearance of modafinil and metabolites may be reduced.Modafinil, a nonamphetamine wakefulness-promoting agent, is a 50:50 racemic mixture of the Does not appear to act as a direct- or indirect-acting dopamine-receptor or αAt usual pharmacologic concentrations, does not bind to certain receptors that regulate sleep and wakefulness (e.g., norepinephrine, serotonin, dopamine, GABA, adenosine, histamine HDoes not inhibit MAO-B or phosphodiesterases 2-5; does not alter plasma melatonin or cortisol hormone profiles.Reinforcing properties in animals; produces psychoactive, euphoric, and subjective effects typical of classic CNS stimulants (e.g., amphetamines, methylphenidate) in humans.Importance of providing copy of written patient information (medication guide) each time modafinil is dispensed; importance of reading this information prior to taking modafinil.Importance of advising clinician of existing or contemplated therapy, including prescription and OTC drugs and/or herbal supplements, as well as any concomitant illnesses.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; discuss use of alternative or concomitant methods of contraception during these periods.Advise that modafinil may affect judgment, thinking, or motor skills.Advise patient that modafinil may improve, but not eliminate, the abnormal tendency to fall asleep.Importance of continuing previously prescribed therapy (e.g., patients with OSAHS should continue using their CPAP machine while sleeping).Importance of advising patients of other important precautionary information.Subject to control under the Federal Controlled Substances Act of 1970 as a schedule IV (C-IV) drug.2.
