Intrauterine growth restriction and spontaneous abortion have been Oc 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 Dosr with this class. Certain of Prrovigil drugs have been associated Nodmal intrauterine growth restriction and spontaneous abortions.
Whether the cases reported with modafinil are drug-related is unknown. In studies of modafinil and armodafinil conducted in rats Wha, armodafinil and rabbits modafinildevelopmental toxicity was observed at clinically relevant plasma exposures.
No effects on Provigi developmental and neurobehavioral parameters were observed in surviving offspring.
Healthcare providers are encouraged to register pregnant patients, or pregnant women Iw enroll themselves in the registry by calling toll free. 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 favoring 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 CGI-C.
Transient leukopenia, which resolved without medical intervention, was also Whaf. In the controlled clinical 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.

In clinical trials, experience in a 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.
Dosing regimen effects of modafinil for improving daytime wakefulness in patients with narcolepsy
In elderly patients, elimination of Whar and its metabolites may 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 Administration 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, perception, 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 reinforcing, 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 individuals experienced with drugs of abuse. Results from this clinical study demonstrated that modafinil produced psychoactive and euphoric effects and feelings consistent with other scheduled CNS stimulants methylphenidate.
In Iz placebo-controlled clinical trial, the effects of modafinil withdrawal were monitored following 9 weeks of modafinil use. There were no reported withdrawal symptoms with modafinil during 14 days of observation, although sleepiness returned in narcoleptic patients. In addition, several intentional acute overdoses occurred; the two largest being mg and mg taken by two subjects participating in foreign depression studies.
None of these study Nornal experienced any unexpected or life-threatening effects. Adverse reactions that were reported at these doses included excitation or agitation, insomnia, and slight or moderate elevations in hemodynamic parameters. Other observed high-dose effects in clinical studies have included anxiety, irritability, aggressiveness, confusion, nervousness, tremor, palpitations, sleep disturbances, nausea, diarrhea, and decreased prothrombin time.
From postmarketing experience, there have been reports of fatal overdoses involving modafinil alone or in combination with other drugs. Symptoms most often accompanying PROVIGIL overdose, alone or in combination with other drugs have included insomnia; central nervous system symptoms such as restlessness, disorientation, confusion, Pgovigil, anxiety, excitation, and hallucination; digestive changes such as nausea and diarrhea; and cardiovascular changes such as tachycardia, bradycardia, hypertension, and chest pain.
The child remained stable. The symptoms associated What Is A Normal Dose Of Provigil 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 a 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 pregelatinized starch. The mechanism s through which modafinil promotes wakefulness is sI. 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, Notmal those of amphetamine, were not antagonized by the dopamine receptor antagonist haloperidol IIs rats.
In addition, alpha-methyl-p-tyrosine, a dopamine synthesis inhibitor, blocks the action of amphetamine, but does not block locomotor https://buymodafinilntx.com/2-provigil-iherb-vyg.php induced by modafinil. In the cat, 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 Dode to its wake-promoting effects and ability to increase locomotor activity in animals, modafinil produces psychoactive and euphoric effects, alterations in mood, 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 acid 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 DDose reach peak concentration t max may be delayed by approximately one hour if taken with food.
Urine alkalinization has no effect on What Is A Normal Dose Of Provigil 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 learn more here acid, Ov at least six other metabolites were present in lower concentrations.
Only 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 Wyat appear to mediate the arousal effects of modafinil.
