🩺 Clinical
Perampanel is used to treat certain types of partial onset seizures (seizures that involve only one part of the brain) in adults and children 4 years of age and older. It is also used in combination with other medications to treat certain types of primary generalized tonic-clonic seizures (formerly known as a grand mal seizure; seizure that involves the entire body) in adults and children 12 years of age or older. Perampanel is in a class of medications called anticonvulsants. It works by decreasing abnormal electrical activity in the brain.

⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Dosing in the absence of moderate or strong CYP3A4 inducers Starting dose: 2 mg once daily orally at bedtime ( 2.1 , 2.2 ) May increase dose based on clinical response and tolerability by increments of 2 mg once daily no more frequently than at weekly intervals ( 2.1 , 2.2 ) Recommended maintenance dose in monotherapy or adjunctive therapy for partial-onset seizures: 8 mg to 12 mg once daily at bedtime ( 2.1 ) Recommended maintenance dose in adjunctive therapy for primary generalized tonic-clonic seizures: 8 mg once daily at bedtime ( 2.2 ) Dosing in the presence of concomitant moderate or strong CYP3A4 inducers : see section
2.3Specific Populations Mild and Moderate Hepatic Impairment: Maximum recommended daily dose is 6 mg (mild) and 4 mg (moderate) once daily at bedtime ( 2.4 ) Severe Hepatic Impairment: Not recommended ( 2.4 ) Severe Renal Impairment or on Hemodialysis: Not recommended ( 2.5 ) Elderly: Increase dose no more frequently than every 2 weeks ( 2.6 )
2.1Dosage for Partial-Onset Seizures Monotherapy or Adjunctive Therapy The recommended starting dosage of perampanel in adults and pediatric patients 4 years of age and older is 2 mg once daily taken orally at bedtime. Increase dosage no more frequently than at weekly intervals by increments of 2 mg once daily based on individual clinical response and tolerability. The recommended maintenance dose range is 8 mg to 12 mg once daily, although some patients may respond to a dose of 4 mg daily.
A dose of 12 mg once daily resulted in somewhat greater reductions in seizure rates than the dose of 8 mg once daily, but with a substantial increase in adverse reactions. Dosage adjustment is recommended with concomitant use of moderate or strong CYP3A4 enzyme inducing drugs, which include certain antiepileptic drugs (AEDs) [see Dosage and Administration (2.3) ] .
2.2Dosage for Primary Generalized Tonic-Clonic Seizures Adjunctive Therapy The recommended starting dosage of perampanel in adults and pediatric patients 12 years of age and older is 2 mg once daily taken orally at bedtime. Increase dosage no more frequently than at weekly intervals by increments of 2 mg once daily based on individual clinical response and tolerability. The recommended maintenance dose is 8 mg once daily taken at bedtime.
Patients who are tolerating perampanel at 8 mg once daily and require further reduction of seizures may benefit from a dose increase up to 12 mg once daily if tolerated. Dosage adjustment is recommended with concomitant use of moderate or strong CYP3A4 enzyme inducing drugs, which include certain AEDs [see Dosage and Administration (2.3) ] .
2.3Dosage Modifications with Concomitant Use of Moderate or Strong CYP3A4 Enzyme Inducers Moderate and strong CYP3A4 inducers, including enzyme-inducing AEDs such as phenytoin, carbamazepine, and oxcarbazepine, cause a reduction in perampanel plasma levels [see Drug Interactions (7.2) , Clinical Pharmacology (12.3) ] . Therefore, in adults and pediatric patients 4 years of age and older receiving these concomitant enzyme-inducing drugs, the recommended starting dosage of perampanel is 4 mg once daily taken orally at bedtime.
Increase dosage by increments of 2 mg once daily based on individual clinical response and tolerability, no more frequently than at weekly intervals. A maintenance dose has not been established in clinical trials. The highest dose studied in patients on concomitant enzyme-inducing AEDs was 12 mg once daily.
When moderate or strong CYP3A4 inducers are introduced or withdrawn from a patient's treatment regimen, the patient should be closely monitored for clinical response and tolerability. Dose adjustment of perampanel may be necessary.
2.4Dosage Adjustment in Patients with Hepatic Impairment In patients with mild and moderate hepatic impairment, the starting dose of perampanel is 2 mg once daily. Increase dosage by increments of 2 mg once daily no more frequently than every 2 weeks. The maximum…

5 WARNINGS AND PRECAUTIONS Suicidal Behavior and Ideation: Monitor for suicidal thoughts or behavior ( 5.2 ) Neurologic Effects: Monitor for dizziness, gait disturbance, somnolence, and fatigue ( 5.3 ) Patients should use caution when driving or operating machinery ( 5.3 ) Falls: Monitor for falls and injuries ( 5.4 ) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multi-Organ Hypersensitivity: Discontinue if no alternate etiology ( 5.5 ) Withdrawal of Antiepileptic Drugs: In patients with epilepsy, there may be an increase in seizure frequency ( 5.6 )
5.1Serious Psychiatric and Behavioral Reactions In the controlled partial-onset seizure clinical trials, hostility- and aggression-related adverse reactions occurred in 12% and 20% of patients randomized to receive perampanel at doses of 8 mg and 12 mg per day, respectively, compared to 6% of patients in the placebo group. These effects were dose-related and generally appeared within the first 6 weeks of treatment, although new events continued to be observed through more than 37 weeks. Perampanel-treated patients experienced more hostility- and aggression-related adverse reactions that were serious, severe, and led to dose reduction, interruption, and discontinuation more frequently than placebo-treated patients.
In general, in placebo-controlled partial-onset seizure clinical trials, neuropsychiatric events were reported more frequently in patients being treated with perampanel than in patients taking placebo. These events included irritability, aggression, anger, and anxiety, which occurred in 2% or greater of perampanel-treated patients and twice as frequently as in placebo-treated patients. Other symptoms that occurred with perampanel and were more common than with placebo included belligerence, affect lability, agitation, and physical assault.
Some of these events were reported as serious and life-threatening. Homicidal ideation and/or threat were exhibited in 0.1% of 4,368 perampanel-treated patients in controlled and open label trials, including non-epilepsy trials. Homicidal ideation and/or threat have also been reported postmarketing in patients treated with perampanel.
In the partial-onset seizure clinical trials, these events occurred in patients with and without prior psychiatric history, prior aggressive behavior, or concomitant use of medications associated with hostility and aggression. Some patients experienced worsening of their pre-existing psychiatric conditions. Patients with active psychotic disorders and unstable recurrent affective disorders were excluded from the clinical trials.
The combination of alcohol and perampanel significantly worsened mood and increased anger. Patients taking perampanel should avoid the use of alcohol [see Drug Interactions (7.3) ]. Similar serious psychiatric and behavioral events were observed in the primary generalized tonic-clonic seizure clinical trial.
In healthy volunteers taking perampanel, observed psychiatric events included paranoia, euphoric mood, agitation, anger, mental status changes, and disorientation/confusional state. In the non-epilepsy trials, psychiatric events that occurred in perampanel-treated patients more often than placebo-treated patients included disorientation, delusion, and paranoia. In the postmarketing setting, there have been reports of psychosis (acute psychosis, hallucinations, delusions, paranoia) and delirium (delirium, confusional state, disorientation, memory impairment) in patients treated with perampanel [see Adverse Reactions (6.2) ] .
Patients, their caregivers, and families should be informed that perampanel may increase the risk of psychiatric events. Patients should be monitored during treatment and for at least 1 month after the last dose of perampanel, and especially when taking higher doses and during the initial few weeks of drug therapy (titration period) or at other times of dose increases. Dose of perampanel should be reduced if these symptoms occur.

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 clinical practice. Partial-Onset Seizures Adult and Adolescent Patients (12 years of age and older) A total of 1,038 patients receiving perampanel (2 mg, 4 mg, 8 mg, or 12 mg once daily) constituted the safety population in the pooled analysis of the placebo-controlled trials (Studies 1, 2, and 3) in patients with partial-onset seizures.
Approximately 51% of patients were female, and the mean age was 35 years. Adverse Reactions Leading to Discontinuation In controlled clinical trials (Studies 1, 2, and 3), the rate of discontinuation as a result of an adverse reaction was 3%, 8%, and 19% in patients randomized to receive perampanel at the recommended doses of 4 mg, 8 mg, and 12 mg per day, respectively, and 5% in patients randomized to receive placebo [see Clinical Studies (14) ]. The adverse reactions most commonly leading to discontinuation (≥1% in the 8 mg or 12 mg perampanel group and greater than placebo) were dizziness, somnolence, vertigo, aggression, anger, ataxia, blurred vision, irritability, and dysarthria [see Warnings and Precautions (5.1 , 5.3) ].
Most Common Adverse Reactions Table 2 gives the incidence in the controlled clinical trials (Studies 1, 2, and 3) of the adverse reactions that occurred in ≥2% of patients with partial-onset seizures in the perampanel 12 mg dose group and more frequent than placebo (in order of decreasing frequency for the 12 mg dose group). The most common dose-related adverse reactions in patients receiving perampanel at doses of 8 mg or 12 mg (≥4% and occurring at least 1% higher than the placebo group) included dizziness (36%), somnolence (16%), fatigue (10%), irritability (9%), falls (7%), nausea (7%), ataxia (5%), balance disorder (4%), gait disturbance (4%), vertigo (4%), and weight gain (4%).
For almost every adverse reaction, rates were higher on 12 mg and more often led to dose reduction or discontinuation. Table 2.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Contraceptives: 12 mg once daily may decrease the effectiveness of hormonal contraceptives containing levonorgestrel ( 7.1 ) Moderate and Strong CYP3A4 Inducers (including carbamazepine, oxcarbazepine, and phenytoin): increase clearance of perampanel and decrease perampanel plasma concentrations. When moderate or strong CYP3A4 inducers are introduced or withdrawn, monitor patients closely. Dose adjustment of perampanel tablets may be necessary ( 2.3 , 7.2 )
7.1Contraceptives With concomitant use, perampanel at a dose of 12 mg per day reduced levonorgestrel exposure by approximately 40% [see Clinical Pharmacology (12.3) ] . Use of perampanel with contraceptives containing levonorgestrel may render them less effective. Additional non-hormonal forms of contraception are recommended [see Use in Specific Populations (8.3) ] .
7.2Moderate and Strong CYP3A4 Inducers The concomitant use of known moderate and strong CYP3A4 inducers including carbamazepine, phenytoin, or oxcarbazepine with perampanel decreased the plasma levels of perampanel by approximately 50% to 67% [see Clinical Pharmacology (12.3) ] . The starting doses for perampanel should be increased in the presence of moderate or strong CYP3A4 inducers [see Dosage and Administration (2.3) ] . When these moderate or strong CYP3A4 inducers are introduced or withdrawn from a patient's treatment regimen, the patient should be closely monitored for clinical response and tolerability.
Dose adjustment of perampanel may be necessary [see Dosage and Administration (2.3) ].
7.3Alcohol and Other CNS Depressants The concomitant use of perampanel and CNS depressants including alcohol may increase CNS depression. A pharmacodynamic interaction study in healthy subjects found that the effects of perampanel on complex tasks such as driving ability were additive or supra-additive to the impairment effects of alcohol [see Clinical Pharmacology (12.3) ]. Multiple dosing of perampanel 12 mg per day also enhanced the effects of alcohol to interfere with vigilance and alertness, and increased levels of anger, confusion, and depression.
These effects may also be seen when perampanel is used in combination with other CNS depressants. Care should be taken when administering perampanel with these agents. Patients should limit activity until they have experience with concomitant use of CNS depressants (e.g., benzodiazepines, narcotics, barbiturates, sedating antihistamines).
Advise patients not to drive or operate machinery until they have gained sufficient experience on perampanel to gauge whether it adversely affects these activities.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm ( 8.1 )
8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (AEDs), such as perampanel, during pregnancy. Encourage women who are taking perampanel during pregnancy to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org. Risk Summary There are no adequate data on the developmental risk associated with use in pregnant women.
In animal studies, perampanel induced developmental toxicity in pregnant rat and rabbit at clinically relevant doses [see Data ] . In the U.S. general population the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown.
Data Animal Data Oral administration of perampanel (1 mg/kg/day, 3 mg/kg/day, or 10 mg/kg/day) to pregnant rats throughout organogenesis resulted in an increase in visceral abnormalities (diverticulum of the intestine) at all doses tested; maternal toxicity was observed at the mid and high doses. In a dose-ranging study at higher oral doses (10 mg/kg/day, 30 mg/kg/day, or 60 mg/kg/day), embryo lethality and reduced fetal body weight were observed at the mid and high doses tested. The lowest dose tested (1 mg/kg/day) is similar to a human dose of 8 mg/day based on body surface area (mg/m 2 ).
Upon oral administration of perampanel (1 mg/kg/day, 3 mg/kg/day, or 10 mg/kg/day) to pregnant rabbits throughout organogenesis, embryo lethality and maternal toxicity were observed at the mid and high doses tested; the no-effect dose for embryo-fetal developmental toxicity in rabbit (1 mg/kg/day) is approximately 2 times a human dose of 8 mg/day based on body surface area (mg/m 2 ). Oral administration of perampanel (1 mg/kg/day, 3 mg/kg/day or 10 mg/kg/day) to rats throughout gestation and lactation resulted in fetal and pup deaths at the mid and high doses (associated with maternal toxicity) and delayed sexual maturation in males and females at the highest dose tested.
No effects were observed on measures of neurobehavioral or reproductive function in the offspring. The no-effect dose for pre- and postnatal developmental toxicity in rat (1 mg/kg/day) is similar to a human dose of 8 mg/day based on body surface area (mg/m 2 ).
8.2Lactation Risk Summary There are no data on the presence of perampanel in human milk, the effects on the breastfed child, or the effects of the drug on milk production. Perampanel and/or its metabolites are present in rat milk, and are detected at concentrations higher than that in maternal plasma. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for perampanel and any potential adverse effects on the breastfed child from perampanel or from the underlying maternal condition.
8.3Females and Males of Reproductive Potential Contraception Use of perampanel may reduce the efficacy of hormonal contraceptives containing levonorgestrel. Advise women taking perampanel who are using a levonorgestrel-containing contraceptive to use an additional non-hormonal form of contraception while using perampanel and for a month after discontinuation [see Drug Interactions (7.1) , Clinical Pharmacology (12.3) ] .
8.4Pediatric Use Safety and effectiveness of perampanel for the treatment of partial-onset seizures have been established in pediatric patients 4 years of age and older. The safety and effectiveness of perampanel in patients 12 years of age and older was established by three randomized double-blind, placebo-controlled, multicenter studies, which included 72 pediatric patients between 12 and 16 years of age exposed to perampanel [see Clinical Pharmacology (12.3)…

In a dose-ranging study at higher oral doses (10 mg/kg/day, 30 mg/kg/day, or 60 mg/kg/day), embryo lethality and reduced fetal body weight were observed at the mid and high doses tested. The lowest dose tested (1 mg/kg/day) is similar to a human dose of 8 mg/day based on body surface area (mg/m 2 ).
Upon oral administration of perampanel (1 mg/kg/day, 3 mg/kg/day, or 10 mg/kg/day) to pregnant rabbits throughout organogenesis, embryo lethality and maternal toxicity were observed at the mid and high doses tested; the no-effect dose for embryo-fetal developmental toxicity in rabbit (1 mg/kg/day) is approximately 2 times a human dose of 8 mg/day based on body surface area (mg/m 2 ). Oral administration of perampanel (1 mg/kg/day, 3 mg/kg/day or 10 mg/kg/day) to rats throughout gestation and lactation resulted in fetal and pup deaths at the mid and high doses (associated with maternal toxicity) and delayed sexual maturation in males and females at the highest dose tested.
No effects were observed on measures of neurobehavioral or reproductive function in the offspring. The no-effect dose for pre- and postnatal developmental toxicity in rat (1 mg/kg/day) is similar to a human dose of 8 mg/day based on body surface area (mg/m 2 ).
🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness of perampanel for the treatment of partial-onset seizures have been established in pediatric patients 4 years of age and older. The safety and effectiveness of perampanel in patients 12 years of age and older was established by three randomized double-blind, placebo-controlled, multicenter studies, which included 72 pediatric patients between 12 and 16 years of age exposed to perampanel [see Clinical Pharmacology (12.3) and Clinical Studies (14.1) ] . Use of perampanel for the treatment of partial-onset seizures in pediatric patients 4 years to less than 12 years of age is supported by evidence from adequate and well-controlled studies of perampanel in patients 12 years of age and older with partial onset seizures, pharmacokinetic data from adult and pediatric patients, and safety data in 225 pediatric patients 4 years to less than 12 years of age treated with perampanel [see Adverse Reactions (6.1) and Clinical Pharmacology (12.3) ] .
The safety and efficacy of perampanel for the adjunctive therapy of primary generalized tonic-clonic seizures in pediatric patients 12 years of age and older was established in a single randomized double-blind, placebo-controlled, multicenter trial (n=164), which included 11 pediatric patients 12 to 16 years of age exposed to perampanel; an additional 6 patients were treated with perampanel in the open-label extension of the study [see Clinical Studies (14.2) ] . The safety and effectiveness of perampanel for the treatment of partial-onset seizures in pediatric patients less than 4 years of age or for the treatment of primary generalized tonic-clonic seizures in pediatric patients less than 12 years of age have not been established.
Juvenile Animal Data Oral administration of perampanel (1 mg/kg/day, 3 mg/kg/day, 3/10/30 mg/kg/day; high dose increased on postnatal days [PND] 28 and 56) to young rats for 12 weeks starting on PND 7 resulted in reduced body weight, reduced growth, neurobehavioral impairment (water maze performance and auditory startle habituation) at the mid and high doses, and delayed sexual maturation at the high doses. CNS signs (reduced activity, incoordination, excessive grooming/scratching), pup death, decreased hindlimb splay, and decreased hindlimb grip strength were observed at all doses.
Effects on pup body weight, pup growth, hindlimb splay, impairment in the water maze performance, and auditory startle persisted after dosing was stopped. A no-effect dose for postnatal developmental toxicity was not identified in this study. Oral administration of perampanel (1 mg/kg/day, 5 mg/kg/day, 5/10 mg/kg/day; high dose increased on PND 56) to juvenile dogs for 33 weeks, starting on PND 42, resulted in CNS signs (incoordination, excessive grooming/licking/scratching, spatial disorientation, and/or ataxic gait) at all doses tested.
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of perampanel did not include sufficient numbers of patients aged 65 and over to determine the safety and efficacy of perampanel in the elderly population. Because of increased likelihood for adverse reactions in the elderly, dosing titration should proceed slowly in patients aged 65 years and older [see Dosage and Administration (2.5) ].
🆘 Overdosage ▾
10 OVERDOSAGE The highest reported overdose of perampanel was 300 mg. Events reported after perampanel overdose include somnolence, stupor, coma, psychiatric or behavioral reactions, altered mental status, and dizziness or gait disturbances. There is no available specific antidote to the overdose reactions of perampanel.
In the event of overdose, standard medical practice for the management of any overdose should be used. An adequate airway, oxygenation, and ventilation should be ensured; monitoring of cardiac rhythm and vital sign measurement is recommended. A certified poison control center should be contacted for updated information on the management of overdose with perampanel.
Due to its long half-life, the reactions caused by perampanel could be prolonged.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Perampanel is a non-competitive antagonist of the ionotropic α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) glutamate receptor on post-synaptic neurons. Glutamate is the primary excitatory neurotransmitter in the central nervous system and is implicated in a number of neurological disorders caused by neuronal over excitation. The precise mechanism by which perampanel exerts its antiepileptic effects in humans is unknown.
12.2Pharmacodynamics Psychomotor Performance In a healthy volunteer study to assess the effects of perampanel tablets on psychomotor performance using a standard battery of assessments including simulated driving, single and multiple daily doses of perampanel 4 mg did not impair simple psychomotor tasks, driving performance, or sensorimotor coordination. Single and multiple doses of 8 mg and 12 mg impaired psychomotor performance in a dose-related manner. Car handling ability was impaired after dosing of perampanel 12 mg, but postural stability was not significantly impaired.
Performance testing returned to baseline within 2 weeks of cessation of perampanel dosing. Interactions with Alcohol In the above study (see Psychomotor Performance ) , when administered to healthy subjects receiving alcohol to achieve a blood concentration of 80 mg/100mL to 100 mg/100 mL, perampanel consistently impaired simple psychomotor performance after single doses of 4 mg to 12 mg, and after 21 days of multiple 12 mg/day doses. The effects of perampanel on complex tasks such as driving ability were additive or supra-additive to the impairment effects of alcohol.
Perampanel enhanced the effects of alcohol on vigilance and alertness, and increased levels of anger, confusion, and depression. Potential to Prolong QT Interval In a placebo-controlled thorough QT study of perampanel in healthy subjects, there was no evidence that perampanel caused QT interval prolongation of clinical significance at doses of 6 mg or 12 mg (i.e., the upper bound of the 95% confidence interval for the largest placebo-adjusted baseline-corrected QTc was below 10 msec). The exposures observed with the 12 mg dose in this study will not cover the exposures expected in patients with hepatic impairment taking doses over 6 mg/day.
At the highest recommended dose (12 mg), perampanel did not prolong the QTc interval to any clinically relevant extent.
12.3Pharmacokinetics Pharmacokinetics of perampanel are similar in healthy subjects, patients with partial-onset seizures, and patients with primary generalized tonic-clonic seizures. The half-life of perampanel is about 105 hours, so that steady state is reached in about 2 to 3 weeks. AUC of perampanel increased in a dose-proportional manner after single-dose administration of 0.2 mg to 12 mg tablets and after multiple-dose administration of 1 mg to 12 mg tablets once daily.
Perampanel oral suspension has comparable bioavailability to perampanel tablets under steady state. Both formulations may be used interchangeably. The pharmacokinetics of perampanel are similar when used as monotherapy or as adjunctive therapy for the treatment of partial-onset seizures (in the absence of concomitant moderate or strong CYP3A4 inducers).
Absorption Perampanel is rapidly and completely absorbed after oral administration with negligible first-pass metabolism. Median time to reach peak concentration (t max ) ranged from 0.5 to 2.5 hours under fasted condition. Co-administration of perampanel tablet with a high fat meal had no impact on the total exposure (AUC 0-inf ) of perampanel and reduced the peak plasma concentration (C max ) of perampanel by 11% to 40%.
The t max was delayed by approximately 1 to 3 hours in fed state compared to that under fasted conditions. Distribution Data from in vitro studies indicate that, in the concentration range of 20 ng/mL to 2000 ng/mL, perampanel is approximately 95 to 96% bound to plasma proteins, mainly bound to albumin and α1-acid gl…
