There are no adequate and well-controlled studies of modafinil in pregnant women. Intrauterine growth restriction and spontaneous abortion have been reported in association with modafinil a mixture of R- and S-modafinil and armodafinil the R-enantiomer of modafinil. Although the pharmacology of modafinil is not identical to that of the sympathomimetic amines, it does share some pharmacologic properties with this class. Certain of these drugs have been associated with intrauterine growth restriction and spontaneous Provigi.

Whether the cases reported with modafinil are drug-related is unknown. In studies of modafinil and armodafinil conducted in rats Provigil Max Daily Dose, armodafinil and rabbits modafinildevelopmental toxicity was observed at clinically relevant plasma exposures.

No effects Provivil postnatal developmental and neurobehavioral parameters were observed in surviving offspring. Healthcare providers are encouraged to register pregnant patients, or pregnant women may enroll themselves in the registry by calling toll Provgil.

Dosing regimen effects of modafinil for improving daytime wakefulness in patients with narcolepsy

It is not known whether modafinil or its metabolites are excreted in human milk. Safety and effectiveness in pediatric patients have not been established. There were no statistically significant differences Provigli modafinil over placebo in prolonging sleep latency as measured by MSLT, or in perceptions of sleepiness as determined by the clinical global impression-clinician scale Dailh.

Transient leukopenia, which resolved without medical intervention, was also observed. In the controlled Provigil Max Daily Dose study, 3 of 38 girls, ages 12 or older, treated with modafinil experienced dysmenorrhea compared to 0 of 10 girls who received placebo. There were three 7 to 9 week, double-blind, placebo-controlled, parallel group studies in children and adolescents aged years with Attention-Deficit Hyperactivity Disorder ADHD.

Although these studies showed statistically significant differences favoring modafinil over placebo in reducing ADHD symptoms as measured by the ADHD-RS school versionthere were 3 cases of serious rash including one case of possible SJS among patients exposed to modafinil in this program.

Modafinil is not approved for use in treating ADHD. In clinical trials, experience in Dpse limited number of modafinil-treated patients who were greater than 65 years of age showed an incidence of adverse reactions similar to other age groups.

In elderly patients, elimination of modafinil and its metabolites MMax be reduced as a consequence of aging.

Therefore, consideration should be given to the use of lower doses and close monitoring in this population [see Dosage and Provigil Max Daily Dose 2. In patients with severe hepatic impairment, the dose of PROVIGIL should be reduced to one-half of that recommended for patients with normal hepatic function [see Dosage and Administration 2. In humans, modafinil produces psychoactive and euphoric effects, alterations in mood, And Provigil Together, thinking, and feelings typical of other CNS stimulants.

In in vitro binding studies, modafinil binds to the dopamine reuptake site and causes an increase in extracellular dopamine, but no increase in dopamine release.

Modafinil is Provlgil, as evidenced by its self-administration in monkeys previously trained to self-administer cocaine. In some studies, modafinil was also partially discriminated as stimulant-like. Patients should be observed for signs of misuse or abuse e. The abuse potential of modafinil, and mg was assessed relative to methylphenidate 45 and 90 mg in an inpatient study in Dosw experienced with Dosd of abuse.

Results from this Doe study demonstrated that modafinil produced psychoactive and euphoric effects and feelings consistent with other scheduled CNS stimulants methylphenidate. In one placebo-controlled clinical trial, the effects of modafinil withdrawal were monitored following Provigil Max Daily Dose weeks of modafinil use.

There were no reported withdrawal symptoms with modafinil during 14 days of Provigil Max Daily Dose, although sleepiness returned in Dailt patients.

In addition, several intentional acute overdoses occurred; Daaily two largest being mg and mg taken by two subjects participating in foreign depression studies. None of these study subjects experienced any unexpected or life-threatening effects. Adverse reactions that were reported at these doses included excitation or agitation, insomnia, and slight or moderate Msx in hemodynamic parameters. Other observed high-dose effects in clinical studies have included anxiety, irritability, aggressiveness, confusion, nervousness, tremor, Provigil Max Daily Dose, sleep disturbances, nausea, diarrhea, and decreased prothrombin time.

From postmarketing experience, there have been reports of fatal overdoses Dosr modafinil alone or in combination with other drugs. Symptoms most often Provigjl PROVIGIL overdose, alone or in combination with other drugs have included insomnia; central nervous system symptoms such as restlessness, disorientation, Provigil Max Daily Dose, agitation, anxiety, excitation, and hallucination; digestive DDose such as nausea and aMx and cardiovascular changes such as tachycardia, bradycardia, hypertension, and chest pain.

The child remained stable. The symptoms associated with overdose in children were similar to those observed in adults. Such overdoses should be managed with primarily supportive care, including cardiovascular monitoring. Modafinil is a racemic compound. Modafinil is Daaily white to off-white, crystalline powder that is practically insoluble in water and cyclohexane.

It is sparingly to slightly soluble in methanol and acetone. PROVIGIL tablets contain mg or mg of modafinil and the following inactive ingredients: croscarmellose sodium, lactose monohydrate, magnesium stearate, microcrystalline cellulose, povidone, and Mad starch. The mechanism s through which modafinil promotes wakefulness is unknown. Modafinil has wake-promoting actions similar to sympathomimetic agents including amphetamine and methylphenidate, although the pharmacologic profile is not identical to that of the sympathomimetic amines.

Modafinil is not a direct- or indirect-acting dopamine receptor agonist. However, in vitro, modafinil binds to the dopamine transporter and inhibits dopamine reuptake. This activity has been associated in vivo with increased extracellular dopamine levels in some brain regions of animals. In genetically engineered mice lacking the dopamine transporter DATmodafinil lacked wake-promoting activity, suggesting that this activity was DAT-dependent. However, the wake-promoting effects of modafinil, unlike those of amphetamine, were not antagonized by the dopamine receptor antagonist haloperidol in rats.

In addition, alpha-methyl-p-tyrosine, a dopamine synthesis inhibitor, blocks the action of amphetamine, but does not block locomotor activity induced by modafinil. In the Provigli, equal wakefulness-promoting doses of methylphenidate and amphetamine increased neuronal activation throughout the brain. Modafinil at an equivalent wakefulness-promoting dose selectively and prominently increased neuronal activation in more discrete regions of the brain.

The relationship of this finding in cats to the effects of modafinil in humans is unknown. In addition to its wake-promoting effects and ability to increase locomotor activity in animals, modafinil produces psychoactive and euphoric effects, alterations in Mxx, perception, thinking, and feelings typical of other CNS stimulants in humans.

Modafinil has reinforcing properties, as evidenced by its self-administration in monkeys previously trained to self-administer cocaine; modafinil was also partially discriminated as stimulant-like. The optical enantiomers of modafinil have similar pharmacological actions in animals.

Two major metabolites of modafinil, modafinil DDaily and modafinil sulfone, do not appear to contribute to the CNS-activating properties of modafinil. Modafinil is a racemic compound, whose enantiomers have different pharmacokinetics e.

The enantiomers do not interconvert. At steady state, total exposure to R-modafinil is approximately three times that for S-modafinil. The effective elimination half-life of modafinil after multiple doses is about 15 hours. Apparent steady states of total modafinil and R-modafinil are reached after days of dosing.

Food has no effect on overall PROVIGIL bioavailability; however, time to reach peak concentration t max may be delayed by approximately one hour if taken with Prlvigil. Urine alkalinization has no Provigil Max Daily Dose on the elimination of modafinil. Metabolism occurs through hydrolytic deamidation, S-oxidation, aromatic ring hydroxylation, and glucuronide conjugation.

The largest fraction of the drug in urine was modafinil acid, but at least six other metabolites were present in lower concentrations.

Dosing regimen effects of modafinil for improving daytime wakefulness in patients with narcolepsy

Provigil Max Daily Dose two metabolites reach appreciable concentrations in plasma, i. In preclinical models, modafinil acid, modafinil sulfone, 2-[ diphenylmethyl sulfonyl]acetic acid and 4-hydroxy modafinil, were inactive or did not appear to mediate the arousal effects of modafinil. In adults, decreases in trough levels of modafinil have sometimes been observed after multiple weeks of dosing, suggesting auto-induction, but the magnitude of the decreases and the inconsistency of their read article suggest that their clinical significance is minimal.

Significant accumulation of modafinil sulfone has been observed after multiple doses due to its long elimination half-life of 40 hours. Due to potential effects from the multiple concomitant medications with which most of the patients were being treated, the apparent difference in modafinil pharmacokinetics may not be attributable solely to the effects of aging.

However, the results suggest that the clearance of modafinil may be reduced in the elderly [see Dosage and Administration 2. The pharmacokinetics and metabolism of modafinil were examined in patients with cirrhosis of the liver 6 men and 3 women.

Clinically 8 of 9 patients were icteric and all had ascites. In vitro data also demonstrated that modafinil produced an apparent concentration-related suppression of expression of CYP2C9 activity.

Other CYP activities did not appear to be affected by modafinil. The existence of multiple pathways for modafinil metabolism, as well as the fact that a non-CYP-related pathway is the most rapid in metabolizing modafinil, suggest that there is a low probability of substantive effects on the overall pharmacokinetic profile of PROVIGIL due to CYP inhibition by concomitant medications.

There was no evidence of tumorigenesis associated with modafinil administration in these studies. However, the mouse study was inadequate because the high dose was not a maximum tolerated dose MTD.

Modafinil was negative in a series of in vitro i. The criteria for narcolepsy include either: 1 recurrent daytime naps or lapses into sleep that occur almost daily for at least three months, plus sudden bilateral loss of postural muscle tone in association with intense emotion cataplexy ; or 2 a complaint of excessive sleepiness or sudden muscle weakness with associated features: sleep paralysis, hypnagogic hallucinations, automatic behaviors, disrupted major sleep episode; and polysomnography demonstrating one of the following: sleep latency less than 10 minutes or rapid eye movement REM sleep latency less than 20 minutes.

For entry into these studies, all patients were required to have objectively documented excessive daytime sleepiness, via a Multiple Sleep Latency Test MSLT with two or more sleep onset REM periods and the absence of any other clinically significant active medical or psychiatric disorder.

For each test session, the subject was told to lie quietly and attempt to sleep. Each test session was terminated after 20 minutes if no sleep occurred or 15 minutes after sleep onset. For a successful trial, both measures had to show statistically significant improvement.

The MWT measures latency in minutes to sleep onset averaged over 4 test sessions at 2 hour intervals following nocturnal polysomnography. For each test session, the subject was asked to attempt to remain awake without using extraordinary measures. Each test session was terminated after 20 minutes if no sleep occurred or 10 minutes after sleep onset.

Patients were rated by evaluators who had no access to any data about the patients other than a measure of Provigil Max Daily Dose baseline severity. Evaluators were not given any specific guidance about the criteria they were to apply when rating patients. Both studies demonstrated improvement in objective and subjective measures of excessive daytime sleepiness for both the mg and mg doses compared to placebo. The criteria include either: 1 excessive sleepiness or insomnia, plus frequent episodes of impaired breathing during sleep, and associated features such as loud snoring, morning headaches and dry mouth upon awakening; or 2 excessive sleepiness or insomnia and polysomnography demonstrating one of the following: more than five obstructive apneas, each greater than 10 seconds in duration, per hour of sleep and one or more of the following: frequent arousals from sleep associated with the Provigil Max Daily Dose, bradytachycardia, and arterial oxygen desaturation in association with the apneas.

CPAP use continued throughout the study. The primary measure of effectiveness was the change from baseline on the ESS at final visit. At week 4, the ESS was reduced by 4. All patients met the criteria for chronic SWD. The criteria include: 1 either, a a primary complaint of excessive sleepiness or insomnia which is temporally associated with a work Provigil Max Daily Dose usually Provigil Max Daily Dose work that occurs during the habitual sleep phase, or b polysomnography and the MSLT demonstrate loss of a normal sleep-wake pattern i.

It should be noted that not all patients with a complaint of sleepiness who are also engaged in shift work meet the criteria for the diagnosis of SWD. In the clinical trial, only patients who were symptomatic for at least 3 months were enrolled. Advise patients to stop taking PROVIGIL and to notify their physician right away if they develop a rash, hives, mouth sores, blisters, peeling skin, trouble swallowing or breathing, or a related allergic phenomenon.

Advise patients not to alter their previous behavior with regard to potentially dangerous activities e. Inform patients that it may be critical that they continue to take their previously prescribed treatments e. Advise patients to stop taking PROVIGIL and contact Provigil Max Daily Dose physician right away if they experience chest pain, rash, depression, anxiety, or signs of psychosis or mania. Advise patients to notify their physician if they become pregnant or intend to become pregnant during therapy.

Caution patients regarding the potential increased risk of pregnancy when using steroidal contraceptives including depot or implantable contraceptives with PROVIGIL and for one month after discontinuation of therapy. There may be new information.
