Fycompa

Approved Uses

Fycompa is used to manage seizures in patients with epilepsy. It is specifically indicated for the following:

• Partial-onset seizures: It is used to treat partial-onset seizures, with or without secondarily generalized seizures, in adults and children 4 years of age and older.
• Primary generalized tonic-clonic seizures: It is used to treat primary generalized tonic-clonic seizures in adults and children 12 years of age and older.

Fycompa is considered an adjunctive therapy, which means it is meant to be taken in combination with other antiepileptic drugs to help control seizure activity.

Targeting Brain Receptors

Fycompa is an antiepileptic medication that targets the way nerve cells communicate in the brain. It specifically focuses on a chemical messenger called glutamate, which is the primary excitatory neurotransmitter in the central nervous system. Glutamate is responsible for sending signals that increase electrical activity between nerve cells.

The Role of AMPA Receptors

For glutamate to send its signal, it must attach to specific docking sites on the surface of nerve cells called AMPA receptors. In a brain experiencing a seizure, there is often too much excitatory activity, causing nerve cells to fire uncontrollably.

Fycompa works as a non-competitive antagonist at these AMPA receptors. This means the medication binds to the receptors and blocks glutamate from attaching to them. By preventing glutamate from activating these sites, Fycompa helps to:

• Reduce the over-stimulation of nerve cells.
• Stabilize electrical activity in the brain.
• Inhibit the abnormal electrical discharges that cause seizures.

While the interaction with AMPA receptors is well-documented, the exact mechanism by which Fycompa exerts its full antiepileptic effects in humans is not entirely understood.

Common Side Effects

Many people taking Fycompa experience mild to moderate side effects. These may include:

• Dizziness or spinning sensations
• Drowsiness or extreme tiredness
• Irritability or anxiety
• Nausea and vomiting
• Weight gain
• Headache
• Blurred or double vision
• Bruising easily
• Problems with balance, coordination, or walking

Serious Side Effects

Some side effects can be severe and require immediate medical attention. Seek help right away if you notice:

• Behavioral and mood changes: New or worsening aggressive behavior, hostility, anger, or thoughts of hurting yourself or others.
• Severe coordination issues: Significant difficulty walking or an increased risk of falling.
• Allergic reactions: Symptoms such as a skin rash, hives, or swelling of the face, lips, or tongue.
• Memory problems: Confusion or difficulty remembering things.

Serious Psychiatric and Behavioral Reactions

Fycompa has a boxed warning because it can cause serious psychiatric and behavioral changes. These reactions may occur in people with or without a history of psychiatric issues. Monitoring for the following changes is important:

• Aggression, hostility, or anger
• Irritability or anxiety
• Homicidal ideation or threats
• Confusion or hallucinations

Suicidal Thoughts and Behavior

Like other antiepileptic drugs, Fycompa may increase the risk of suicidal thoughts or actions. This risk can appear as early as one week after starting the medication. Changes in mood, behavior, or feelings should be reported to a healthcare provider immediately.

Neurologic and Physical Effects

This medication can cause significant neurologic side effects that may affect daily activities. These include:

• Dizziness and Vertigo: These are common and may increase the risk of falling.
• Somnolence and Fatigue: Extreme sleepiness or tiredness can occur.
• Gait and Coordination Issues: Difficulty walking or lack of muscle coordination is possible.

Withdrawal and Seizure Risk

Stopping Fycompa suddenly can increase the frequency of seizures or lead to status epilepticus, a life-threatening condition. The dose is typically reduced gradually under medical supervision.

Other Precautions

Fycompa may interact with other substances and medications:

• Alcohol: Drinking alcohol while taking this medication can worsen side effects like sleepiness and impaired coordination.
• Hormonal Contraceptives: Fycompa may make certain birth control pills less effective.
• Liver and Kidney Function: People with severe liver or kidney impairment may need dose adjustments or may be advised against using this medication.

Pregnancy

There is limited research regarding the use of Fycompa in pregnant individuals. In animal studies, high doses of the medication were associated with developmental issues, but it is not known if these same effects occur in humans. Healthcare providers generally only recommend this medication during pregnancy if the potential benefit to the patient outweighs the potential risk to the fetus.

If you become pregnant while taking Fycompa, you should talk to your doctor about the North American Antiepileptic Drug (NAAED) Pregnancy Registry. This registry monitors the health of individuals and their babies to collect more information on the safety of seizure medications during pregnancy.

Contraception

Fycompa can interact with certain types of hormonal birth control. Specifically, it may make contraceptives containing levonorgestrel less effective. If you use hormonal birth control, your healthcare provider may suggest using an additional non-hormonal method, such as condoms, to prevent pregnancy while taking this medication.

Breastfeeding

It is currently unknown if Fycompa passes into human breast milk. Research in animals has shown that the drug can be present in milk, which raises concerns about potential side effects in a nursing infant. Because the risks are not fully understood, you should discuss with your doctor whether to continue breastfeeding or to stop taking the medication, depending on your medical needs.

Available Forms

Fycompa is provided in two primary administration forms for oral use:

• Oral Tablets: These are film-coated tablets designed to be taken by mouth.
• Oral Suspension: This is a liquid formulation of the medication. It is usually packaged with a bottle and a specific oral syringe to ensure the correct amount is measured.

FDA Approval and Indications

Fycompa (perampanel) is approved by the U.S. Food and Drug Administration (FDA) for the treatment of epilepsy. It is indicated for the following uses:

• Partial-onset seizures, with or without secondarily generalized seizures, in patients 4 years of age and older.
• Primary generalized tonic-clonic seizures in patients 12 years of age and older.

Boxed Warning

The FDA requires a boxed warning for Fycompa because it can cause serious psychiatric and behavioral adverse reactions. These reactions may include:

• Aggression, hostility, or irritability.
• Anger and anxiety.
• Homicidal ideation or threats.

These symptoms can occur in patients with or without a prior history of psychiatric disorders or substance abuse. Patients and caregivers are advised to monitor for any changes in mood, behavior, or personality, particularly when starting the medication or during dose increases.

Regulatory Classification

Fycompa is classified by the Drug Enforcement Administration (DEA) as a Schedule III (CIII) controlled substance. This classification is due to the potential for abuse or physical and psychological dependence. Because of this status, there are specific federal and state regulations regarding how the medication is prescribed and refilled.

Factors Influencing Cost

The price of Fycompa can be influenced by several factors, including the specific dosage form (tablets or oral suspension) and the strength of the medication. Out-of-pocket costs are also determined by whether a patient has health insurance and the specific terms of their pharmacy benefit plan.

Insurance and Prior Authorization

Many insurance providers require prior authorization for Fycompa. This means the prescribing doctor must provide additional information to the insurance company to justify the medical necessity of the drug before the plan will cover the cost. Patients may also be responsible for a co-payment or co-insurance amount based on the drug's tier in their plan's formulary.

Generic Perampanel

Generic versions of perampanel may be available for certain strengths. Generic drugs are typically less expensive than brand-name medications while providing the same therapeutic effect. Patients should consult their pharmacist or healthcare provider to see if a generic version is an option for their specific prescription.

Assistance Programs

For individuals who have difficulty affording their medication, there may be patient assistance programs or manufacturer coupons available. These programs can help lower the cost for eligible patients, including those with commercial insurance or those who are uninsured.
