What are the uses of this medicine?

FYCOMPA is a prescription medicine used:

• to treat partial-onset seizures with or without secondarily generalized seizures in people with epilepsy who are 4 years of age and older.
• with other medicines to treat primary generalized tonic-clonic seizures in people with epilepsy who are 12 years of age and older.

How does this medicine work?

• Perampanel (per am' pan el) is a glutamate receptor antagonist that is used to treat severe or refractory partial onset seizures.
• Perampanel binds to the alpha-amino-3-hydroxyl-5-methyl-4-isooxazole-propionate receptor (AMPAR) for glutamate, a major central nervous system excitatory neurotransmitter.
• The inhibition of the AMPAR leads to reduction in seizure activity in animal models as well as in patients with difficult to control seizures.
• In several large, prelicensure randomized controlled trials, addition of perampanel to conventional anticonvulsant medications led to improved control of epilepsy attributed to partial onset seizures.

Who Should Not Use this medicine ?

• This medicine have no usage limitations.

What drug interactions can this medicine cause?

• Use of FYCOMPA with contraceptives containing levonorgestrel may render them less effective. Additional non-hormonal forms of contraception are recommended.
• The starting doses for FYCOMPA should be increased in the presence of moderate or strong CYP3A4 inducers (including carbamazepine, phenytoin, or oxcarbazepine).
• The concomitant use of FYCOMPA and CNS depressants including alcohol may increase CNS depression.

Is this medicine FDA approved?

• Perampanel was approved for use in the United States in 2012 as an anticonvulsant to be used in combination with other agents as adjunctive therapy of partial onset seizures.

How should this medicine be used?

Recommended dosage: Dosage for Partial-Onset Seizures:

• The recommended starting dosage of FYCOMPA 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.
• May increase dose based on clinical response and tolerability by increments of 2 mg once daily no more frequently than at weekly intervals

Recommended maintenance dose in monotherapy or adjunctive therapy for partial-onset seizures: 8 mg to 12 mg once daily at bedtime

Dosage for Primary Generalized Tonic-Clonic Seizures:

• The recommended starting dosage of FYCOMPA 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.

Recommended maintenance dose in adjunctive therapy for primary generalized tonic-clonic seizures:

• 8 mg once daily at bedtime

Dosage Modifications with Concomitant Use of Moderate or Strong CYP3A4 Enzyme Inducers:

• 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.

Dosage Adjustment in Patients with Hepatic Impairment

• In patients with mild and moderate hepatic impairment, the starting dose of FYCOMPA is 2 mg once daily.
• Increase dosage by increments of 2 mg once daily no more frequently than every 2 weeks.
• The maximum recommended daily dose is 6 mg for patients with mild hepatic impairment and 4 mg for patients with moderate hepatic impairment.

Administration:

• Take FYCOMPA exactly as your healthcare provider tells you. Your healthcare provider will tell you how much FYCOMPA to take and when to take it. FYCOMPA is usually taken 1 time a day at bedtime.
• Your healthcare provider may change the dose. Do not change the dose without talking to your healthcare provider.

• A serious allergic reaction

What special precautions should I follow?

• Antiepileptic drugs (AEDs), including FYCOMPA, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Monitor for suicidal thoughts or behavior.
• FYCOMPA caused dose-related increases in events related to dizziness and disturbance in gait or coordination. Monitor for dizziness, gait disturbance, somnolence, and fatigue.
• Do not drive, operate heavy machinery, or do other dangerous activities until you know how FYCOMPA affects you. FYCOMPA may make you dizzy, sleepy, or tired.
• Do not drink alcohol or take other medicines that make you sleepy or dizzy while taking FYCOMPA until you talk to your healthcare provider. FYCOMPA taken with alcohol or medicines that cause sleepiness or dizziness may make your sleepiness or dizziness worse. FYCOMPA when taken with alcohol may also make your mood worse, increase anger, confusion, and depression.
• An increased risk of falls, in some cases leading to serious injuries including head injuries and bone fracture, occurred in patients being treated with FYCOMPA. Monitor for falls and injuries.
• Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), also known as Multiorgan hypersensitivity, has been reported in patients taking antiepileptic drugs, including FYCOMPA. Discontinue if no alternate etiology
• There is the potential of increased seizure frequency in patients with seizure disorders when antiepileptic drugs are withdrawn abruptly. In patients with epilepsy, there may be an increase in seizure frequency.

What to do in case of emergency/overdose?

Symptoms of overdosage may include:

• somnolence
• stupor
• coma
• psychiatric or behavioral reactions
• altered mental status

Treatment of overdosage:

• There is no available specific antidote to the overdose reactions of FYCOMPA.
• 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.
• Due to its long half-life, the reactions caused by FYCOMPA could be prolonged.
