🩺 Clinical
Armodafinil is used to treat excessive sleepiness caused by narcolepsy (a condition that causes excessive daytime sleepiness) or shift work sleep disorder (sleepiness during scheduled waking hours and difficulty falling asleep or staying asleep during scheduled sleeping hours in people who work at night or on rotating shifts). Armodafinil is also used along with breathing devices or other treatments to prevent excessive sleepiness caused by obstructive sleep apnea/hypopnea syndrome (OSAHS; a sleep disorder in which the patient briefly stops breathing or breathes shallowly many times during sle...

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Armodafinil tablets are indicated to improve wakefulness in adult patients with excessive sleepiness associated with obstructive sleep apnea (OSA), narcolepsy, or shift work disorder (SWD). Limitations of Use In OSA, armodafinil tablets are indicated to treat excessive sleepiness and not as treatment for the underlying obstruction. If continuous positive airway pressure (CPAP) is the treatment of choice for a patient, a maximal effort to treat with CPAP for an adequate period of time should be made prior to initiating armodafinil tablets for excessive sleepiness.
Armodafinil tablets are indicated to improve wakefulness in adult patients with excessive sleepiness associated with obstructive sleep apnea (OSA), narcolepsy, or shift work disorder (SWD). ( 1 ) Limitations of Use In OSA, armodafinil tablets are indicated to treat excessive sleepiness and not as treatment for the underlying obstruction.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION The recommended dosage of armodafinil tablets for each indication is as follows: OSA or Narcolepsy: 150 mg to 250 mg once a day in the morning. ( 2.1 ) SWD: 150 mg once a day, taken approximately one hour prior to start of the work shift. ( 2.2 ) Hepatic Impairment: reduced dose in patients with severe hepatic impairment. ( 2.3 , 12.3 ) Geriatric Patients: consider lower dose. ( 2.4 , 12.3)
2.1Dosage in Obstructive Sleep Apnea (OSA) and Narcolepsy The recommended dosage of armodafinil tablets for patients with OSA or narcolepsy is 150 mg to 250 mg taken orally once a day as a single dose in the morning. In patients with OSA, doses up to 250 mg/day, given as a single dose, have been well tolerated, but there is no consistent evidence that these doses confer additional benefit beyond that of the 150 mg/day dose [see Clinical Pharmacology (12.3 ) and Clinical Studies (14.1 , 14.2 )].
2.2Dosage in Shift Work Disorder (SWD) The recommended dosage of armodafinil tablets for patients with SWD is 150 mg taken orally once a day as a single dose approximately 1 hour prior to the start of their work shift.
2.3Dosage Modification in Patients with Severe Hepatic Impairment In patients with severe hepatic impairment, the dosage of armodafinil tablets should be reduced [see Use in Specific Populations ( 8.6 ) and Clinical Pharmacology ( 12.3 )].
2.4Use in Geriatric Patients Consideration should be given to the use of lower doses and close monitoring in geriatric patients [see Use in Specific Populations ( 8.5 )].

⛔ Contraindications ▾
4 CONTRAINDICATIONS Armodafinil tablets are contraindicated in patients with known hypersensitivity to modafinil or armodafinil or its inactive ingredients [see Warnings and Precautions (5.1 , 5.2, 5.3) ]. Armodafinil tablets are contraindicated in patients with known hypersensitivity to modafinil or armodafinil
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Serious Rash, including Stevens-Johnson Syndrome: discontinue armodafinil tablets at the first sign of rash, unless the rash is clearly not drug-related. ( 5.1 ) DRESS/Multi-organ Hypersensitivity Reactions: if suspected, discontinue armodafinil tablets. ( 5.2 ) Angioedema and Anaphylaxis Reactions: if suspected, discontinue armodafinil tablets.
( 5.3 ) Persistent Sleepiness: assess patients frequently for degree of sleepiness and, if appropriate, advise patients to avoid driving or engaging in any other potentially dangerous activity. ( 5.4 ) Psychiatric Symptoms: use particular caution in treating patients with a history of psychosis, depression, or mania. Consider discontinuing armodafinil tablets if psychiatric symptoms develop.
( 5.5 ) Known Cardiovascular Disease: consider increased monitoring. ( 5.7 )
5.1Serious Dermatologic Reactions, including Stevens-Johnson Syndrome and Toxic Epidermal Necrosis Serious rash requiring hospitalization and discontinuation of treatment has been reported in association with the use of armodafinil or modafinil (the racemic mixture of S- and R-enantiomers). Armodafinil tablets have not been studied in pediatric patients in any setting and are not approved for use in pediatric patients for any indication. In clinical trials of modafinil, the incidence of rash resulting in discontinuation was approximately 0.8% (13 per 1,585) in pediatric patients (age <17 years); these rashes included 1 case of possible Stevens-Johnson Syndrome (SJS) and 1 case of apparent multi-organ hypersensitivity reaction/ Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) [see Warnings and Precautions (5.2)].
Several of the cases were associated with fever and other abnormalities (e.g., vomiting, leukopenia). The median time to rash that resulted in discontinuation was 13 days. No such cases were observed among 380 pediatric patients who received placebo.
Skin and mouth sores, blistering, and ulceration have been reported with modafinil and armodafinil in the postmarketing setting. Recurrence of signs and symptoms of serious dermatologic reactions following rechallenge has been reported in some cases. Rare cases of serious or life-threatening rash, including SJS and toxic epidermal necrolysis (TEN), have been reported in adults and children in worldwide postmarketing experience with modafinil and armodafinil.
There are no factors, including duration of therapy, that are known to predict the risk of occurrence or the severity of rash associated with modafinil or armodafinil tablets. In cases where the time to onset was reported, serious rash occurred 1 day to 2 months after initiation of treatment, but isolated cases of serious dermatologic reactions have been reported with symptoms beginning after prolonged treatment (e.g., 3 months). Although benign rashes also occur with armodafinil tablets, it is not possible to reliably predict which rashes will prove to be serious.
Accordingly, armodafinil tablets should be discontinued at the first sign of rash, skin or mouth sores, or blistering or ulceration, unless the rash is clearly not drug-related. Discontinuation of treatment may not prevent a rash from becoming life-threatening or permanently disabling or disfiguring.
5.2Drug Reaction with Eosinophilia and System Symptoms (DRESS)/Multiorgan Hypersensitivity DRESS, also known as multi-organ hypersensitivity, has been reported with armodafinil tablets. DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling, in association with other organ system involvement, such as hepatitis, nephritis, hematologic abnormalities, myocarditis, or myositis, sometimes resembling an acute viral infection. Eosinophilia is often present.
This disorder is variable in its expression, and other organ systems not noted here may be involved. It is important to note that early manifestations of hypersensitivity (e.g., fever, lymphadenopathy) may be present eve…

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Armodafinil tablets have been evaluated for safety in over 1,100 patients with excessive sleepiness associated with OSA, SWD, and narcolepsy. Most Common Adverse Reactions In the placebo-controlled clinical trials, the most common adverse reactions (≥ 5%) associated with the use of armodafinil tablets more frequently than in placebo-treated patients were headache, nausea, dizziness, and insomnia.
The adverse reaction profile was similar across the studies. Table 1 presents the adverse reactions that occurred at a rate of 1% or more and were more frequent in armodafinil tablets-treated patients than in placebo-treated patients in the placebo-controlled clinical trials.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Effects of Armodafinil Tablets on CYP3A4/5 Substrates The clearance of drugs that are substrates for CYP3A4/5 (e.g., steroidal contraceptives, cyclosporine, midazolam, and triazolam) may be increased by armodafinil tablets via induction of metabolic enzymes, which results in lower systemic exposure. Dosage adjustment of these drugs should be considered when these drugs are used concomitantly with armodafinil tablets [see Clinical Pharmacology (12.3) ]. The effectiveness of steroidal contraceptives may be reduced when used with armodafinil tablets and for one month after discontinuation of therapy.
Alternative or concomitant methods of contraception are recommended for patients taking steroidal contraceptives (e.g., ethinyl estradiol) when treated concomitantly with armodafinil tablets and for one month after discontinuation of armodafinil tablets treatment. Blood levels of cyclosporine may be reduced when used with armodafinil tablets. Monitoring of circulating cyclosporine concentrations and appropriate dosage adjustment for cyclosporine should be considered when used concomitantly with armodafinil tablets.
Effects of Armodafinil Tablets on CYP2C19 Substrates Elimination of drugs that are substrates for CYP2C19 (e.g., phenytoin, diazepam, propranolol, omeprazole, and clomipramine) may be prolonged by armodafinil tablets via inhibition of metabolic enzymes, with resultant higher systemic exposure. Dose reduction of these drugs may be required when these drugs are used concomitantly with armodafinil tablets. Warfarin More frequent monitoring of prothrombin times/INR should be considered whenever armodafinil tablets are coadministered with warfarin [see Clinical Pharmacology (12.3) ].
Monoamine Oxidase (MAO) Inhibitors Caution should be used when concomitantly administering MAO inhibitors and armodafinil tablets. Steroidal contraceptives (e.g., ethinyl estradiol): use alternative or concomitant methods of contraception while taking armodafinil tablets and for one month after discontinuation of armodafinil tablets treatment. ( 7 ) Cyclosporine: blood concentrations of cyclosporine may be reduced.
( 7 ) CYP2C19 substrates, such as omeprazole, phenytoin, and diazepam: exposure of these medications may be increased. ( 7 )
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: based on animal data, may cause fetal harm. ( 8.1 )
8.1Pregnancy Risk Summary Limited available data on armodafinil use in pregnant women are insufficient to inform a drug associated risk of adverse pregnancy outcomes. Intrauterine growth restriction and spontaneous abortion have been reported in association with armodafinil and modafinil. Although the pharmacology of armodafinil is not identical to that of the sympathomimetic amines, armodafinil shares some pharmacologic properties with this class [see Clinical Pharmacology (12.1) ].
Some sympathomimetics have been associated with intrauterine growth restriction and spontaneous abortions. In animal reproduction studies of armodafinil (R-modafinil) and modafinil (a mixture of R-and S-modafinil) conducted in pregnant rats (armodafinil, modafinil) and rabbits (modafinil) during organogenesis, evidence of developmental toxicity (increased embryofetal and offspring mortality, decreased fetal growth) was observed at clinically relevant plasma exposures. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes.
The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data Oral administration of armodafinil (60, 200, or 600 mg/kg/day) to pregnant rats throughout organogenesis resulted in decreased fetal body weight and increased incidences of fetal variations indicative of growth delay at the highest dose, which was also maternally toxic.
The highest no-effect dose for embryofetal developmental toxicity in rat (200 mg/kg/day) was associated with a plasma armodafinil exposure (AUC) less than that in humans at the maximum recommended human dose (MRHD) of armodafinil (250 mg/day). Modafinil (50, 100, or 200 mg/kg/day) administered orally to pregnant rats throughout organogenesis produced an increase in resorptions and an increased incidence of fetal variations at the highest dose tested. The higher no-effect dose for embryofetal developmental toxicity (100 mg/kg/day) was associated with a plasma armodafinil AUC less than that in humans at the MRHD of armodafinil tablets.
However, in a subsequent rat study of up to 480 mg/kg/day of modafinil, no adverse effects on embryofetal development were observed. In a study in which modafinil (45, 90, or 180 mg/kg/day) was orally administered to pregnant rabbits during organogenesis, embryofetal death was increased at the highest dose. The highest no-effect dose for developmental toxicity (100 mg/kg/day) was associated with a plasma armodafinil AUC less than that in humans at the MRHD of armodafinil tablets.
Modafinil administration to rats throughout gestation and lactation at oral doses of up to 200 mg/kg/day resulted in decreased viability in the offspring at doses greater than 20 mg/kg/day, a dose resulting in a plasma armodafinil AUC less than that in humans at the MRHD of armodafinil tablets. No effects on postnatal developmental and neurobehavioral parameters were observed in surviving offspring.
8.2Lactation Risk Summary There are no data on the presence of armodafinil or its metabolites in human milk, the effects on the breastfed infant, or the effect of this drug on milk production. Modafinil was present in rat milk when animals were dosed during the lactation period. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for armodafinil and any potential adverse effects on the breastfed child from armodafinil or from the underlying maternal condition.

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness in pediatric patients have not been established. Serious rash has been seen in pediatric patients receiving modafinil [see Warnings and Precautions (5.1) ].
🧓 Geriatric Use ▾
8.5Geriatric Use In elderly patients, elimination of armodafinil 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 (2.4) and Clinical Pharmacology (12.3) ].
🆘 Overdosage ▾
10 OVERDOSAGE Fatal overdoses involving modafinil alone or involving armodafinil tablets or modafinil in combination with other drugs have been reported in the postmarketing setting. Symptoms most often accompanying armodafinil tablets or modafinil overdose, alone or in combination with other drugs, have included anxiety, dyspnea, insomnia; central nervous system symptoms such as restlessness, disorientation, confusion, excitation and hallucination; digestive changes such as nausea and diarrhea; and cardiovascular changes such as tachycardia, bradycardia, hypertension, and chest pain.
No specific antidote exists for the toxic effects of an armodafinil tablets overdose. Such overdoses should be managed with primarily supportive care, including cardiovascular monitoring.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The mechanism(s) through which armodafinil promotes wakefulness is unknown. Armodafinil (R-modafinil) has pharmacological properties similar to those of modafinil (a mixture of R- and S-modafinil), to the extent tested in animal and in vitro studies. The R- and S-enantiomers have similar pharmacological actions in animals.
Armodafinil and modafinil have wake-promoting actions similar to sympathomimetic agents including amphetamine and methylphenidate, although their pharmacologic profile is not identical to that of the sympathomimetic amines. Modafinil-induced wakefulness can be attenuated by the α1-adrenergic receptor antagonist, prazosin; however, modafinil is inactive in other in vitro assay systems known to be responsive to α-adrenergic agonists such as the rat vas deferens preparation. Armodafinil is an indirect dopamine receptor agonist; both armodafinil and modafinil bind in vitro to the dopamine transporter and inhibit dopamine reuptake.
For modafinil, 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 (DAT), modafinil 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 addition 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.
Based on nonclinical studies, two major metabolites, acid and sulfone, of modafinil or armodafinil, do not appear to contribute to the CNS-activating properties of the parent compounds.
12.3Pharmacokinetics Armodafinil exhibits linear time-independent kinetics following single and multiple oral dose administration. Increase in systemic exposure is proportional over the dose range of 50 to 400 mg. No time-dependent change in kinetics was observed through 12 weeks of dosing.
Apparent steady state for armodafinil was reached within 7 days of dosing. At steady state, the systemic exposure for armodafinil is 1.8 times the exposure observed after a single dose. The concentration-time profiles of the R-enantiomer following administration of a single-dose of 50 mg armodafinil tablets or 100 mg modafinil (modafinil, a 1:1 mixture of R- and S-enantiomers) are nearly superimposable.
However, the C max and AUC 0-∞ , of armodafinil at steady-state were approximately 37% and 70% higher, respectively, following administration of 200 mg armodafinil tablets than the corresponding values of modafinil following administration of 200 mg modafinil due to the more rapid clearance of the S-enantiomer (elimination half-life approximately 4 hours) as compared to the R-enantiomer. Absorption Armodafinil is readily absorbed after oral administration. The absolute oral bioavailability was not determined due to the aqueous insolubility of armodafinil, which precluded intravenous administration.
Peak plasma concentrations are attained at approximately 2 hours in the fasted state. Food effect on the overall bioavailability of armodafinil is considered minimal; however, time to reach peak concentration (t max ) may be delayed by approximately 2-4 hours in the fed state. Since the delay in t max is also associated with elevated plasma concentrations later in time, food can potentially affect the onset and time course of p…
🧬 Mechanism of Action ▾
12.1Mechanism of Action The mechanism(s) through which armodafinil promotes wakefulness is unknown. Armodafinil (R-modafinil) has pharmacological properties similar to those of modafinil (a mixture of R- and S-modafinil), to the extent tested in animal and in vitro studies. The R- and S-enantiomers have similar pharmacological actions in animals.
Armodafinil and modafinil have wake-promoting actions similar to sympathomimetic agents including amphetamine and methylphenidate, although their pharmacologic profile is not identical to that of the sympathomimetic amines. Modafinil-induced wakefulness can be attenuated by the α1-adrenergic receptor antagonist, prazosin; however, modafinil is inactive in other in vitro assay systems known to be responsive to α-adrenergic agonists such as the rat vas deferens preparation. Armodafinil is an indirect dopamine receptor agonist; both armodafinil and modafinil bind in vitro to the dopamine transporter and inhibit dopamine reuptake.
For modafinil, 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 (DAT), modafinil 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 addition 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.
Based on nonclinical studies, two major metabolites, acid and sulfone, of modafinil or armodafinil, do not appear to contribute to the CNS-activating properties of the parent compounds.
