Banzel

Approved Uses

Banzel is primarily prescribed as an add-on (adjunctive) treatment for seizures associated with Lennox-Gastaut syndrome (LGS). LGS is a severe form of epilepsy that typically begins in early childhood and is characterized by multiple types of seizures, such as:

• Atonic seizures, also known as drop attacks
• Tonic seizures, which involve muscle stiffening
• Atypical absence seizures, often described as staring spells

This medication is used in combination with other anti-epileptic drugs to help reduce the frequency of these seizures. It is approved for use in both adults and pediatric patients who are at least 1 year of age.

How It Is Prescribed

Because Banzel is an adjunctive therapy, it is not intended to be used as a standalone treatment. It is typically added to a patient's existing seizure medication regimen when current treatments are not providing sufficient control of seizures related to Lennox-Gastaut syndrome.

Mechanism of Action

Banzel belongs to a class of medications known as anticonvulsants or antiepileptics. It is used to treat seizures associated with Lennox-Gastaut syndrome by influencing how nerve cells in the brain communicate.

The exact way Banzel works is not completely understood. However, evidence suggests it affects sodium channels, which are responsible for generating electrical signals in the brain. During a seizure, these signals become overactive and fire too quickly.

Banzel is thought to help by:

• Keeping sodium channels in an inactive state for a longer period.
• Preventing nerve cells from firing electrical signals too rapidly or repetitively.
• Reducing the overall excessive electrical activity that causes seizures.

By stabilizing these electrical signals, the medication helps decrease the frequency and intensity of seizure activity.

Common Side Effects

Many people taking Banzel experience mild side effects. These often include:

• Headache
• Dizziness
• Drowsiness or extreme tiredness
• Nausea and vomiting
• Loss of appetite
• Double vision
• Tremors or difficulty with coordination and walking

Serious Side Effects

While less common, some side effects can be severe. Contact a healthcare provider immediately if you experience:

• Heart rhythm changes: Banzel can shorten the QT interval, which may affect how the heart beats. This is a particular concern for people with certain pre-existing heart conditions.
• Mood or behavior changes: Like other seizure medications, Banzel may cause suicidal thoughts or actions, new or worsening depression, or anxiety.
• Severe allergic reactions: Symptoms may include a skin rash, fever, or swollen glands. These can be signs of a serious multi-organ hypersensitivity reaction known as DRESS.
• Worsening seizures: Any significant change in the frequency or severity of seizures should be reported.

Suicidal Behavior and Ideation

Antiepileptic drugs, including Banzel, increase the risk of suicidal thoughts or behavior. Monitoring for the emergence or worsening of depression, suicidal thoughts, or any unusual changes in mood or behavior is important for those taking this medication.

Heart Rhythm Concerns

Banzel should not be used by individuals with Familial Short QT Syndrome. The drug can shorten the QT interval, a measurement of the heart's electrical cycle, which may lead to heart rhythm complications.

Multi-organ Hypersensitivity

Serious and potentially life-threatening allergic reactions, such as Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), have occurred. These reactions are more common in children and typically present with fever and rash, often involving internal organs like the liver or kidneys.

Central Nervous System Effects

Banzel can cause significant central nervous system symptoms, including:

• Extreme sleepiness or fatigue
• Dizziness
• Problems with coordination or walking

These symptoms may interfere with activities that require alertness or physical stability.

Seizure Risk Upon Discontinuation

Abruptly stopping Banzel can increase the frequency of seizures or lead to status epilepticus, a condition of prolonged seizure activity. Gradual dose reduction is typically recommended when discontinuing the drug.

Blood Count Changes

Some patients may develop leukopenia, which is a decrease in the number of white blood cells. Periodic monitoring of blood counts may be necessary during treatment.

Pregnancy

There is limited information regarding the safety of Banzel during human pregnancy. In animal studies, high doses of the drug were associated with developmental issues, though it is unclear if these effects occur in humans. Healthcare providers generally weigh the risks of the medication against the risks of untreated seizures, which can be harmful to both the pregnant person and the fetus.

Individuals who are pregnant or planning to become pregnant should discuss their treatment plan with a doctor. Those who take Banzel during pregnancy may be encouraged to join the North American Antiepileptic Drug (NAAED) Pregnancy Registry to assist in monitoring the outcomes of the pregnancy.

Breastfeeding

It is not known if Banzel passes into human breast milk. Because many drugs are excreted in milk and have the potential to cause side effects in a nursing infant, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the medication to the mother.

Contraception

Banzel may reduce the effectiveness of hormonal contraceptives, including birth control pills, injections, patches, and implants. To prevent unintended pregnancy, healthcare providers often recommend using an additional or alternative method of non-hormonal birth control while taking this medication.

Available Forms

Banzel is produced in two primary formulations for oral administration:

• Film-Coated Tablets: These tablets are designed to be swallowed whole with water. Depending on the specific tablet, they may be scored, allowing them to be broken into equal halves if necessary. They can also be crushed for administration.
• Oral Suspension: This is a liquid version of the medication. It is typically used for patients who have difficulty swallowing solid tablets. The suspension must be shaken well before each use to ensure the medication is evenly distributed throughout the liquid.

FDA Approval History

The U.S. Food and Drug Administration (FDA) first approved Banzel in November 2008. It was initially indicated for use in adults and children 4 years of age and older. In 2015, the FDA expanded the approved use to include pediatric patients as young as 1 year old.

Approved Indications

Banzel is approved as an adjunctive (add-on) therapy for the treatment of seizures associated with Lennox-Gastaut syndrome (LGS). LGS is a severe form of epilepsy that typically begins in childhood and is characterized by multiple types of seizures and developmental delays.

Regulatory Status and Availability

Banzel is classified as an antiepileptic drug (AED). While it is a brand-name medication, generic versions of rufinamide have been approved by the FDA and are available on the market. There is currently no Risk Evaluation and Mitigation Strategy (REMS) program required for this medication.

Safety Communications

Like other antiepileptic medications, Banzel carries a general regulatory warning regarding the increased risk of suicidal thoughts or behavior. Patients starting this medication are typically monitored for changes in mood or behavior. It is also known to cause a shortening of the QT interval on an electrocardiogram (ECG), which is a specific regulatory safety consideration for patients with certain heart conditions.

Generic Availability

Banzel is the brand name for the drug rufinamide. Generic versions of rufinamide are available in both tablet and oral suspension forms. Generic medications typically cost significantly less than brand-name versions while providing the same active ingredients and therapeutic effects.

Factors Affecting Price

The amount you pay for Banzel or generic rufinamide can vary based on several factors:

• Insurance Coverage: Most private insurance plans, Medicare Part D, and Medicaid cover generic rufinamide. The specific tier of the drug on your plan's formulary will determine your out-of-pocket copay or coinsurance.
• Pharmacy Selection: Prices may differ between retail pharmacies, and some mail-order pharmacy services may offer lower costs for a 90-day supply.
• Dosage Form: The cost may differ between the oral tablets and the liquid suspension, depending on the required volume and concentration.

Financial Assistance Programs

For patients who have difficulty affording their medication, there may be options to help manage costs. The manufacturer of brand-name Banzel sometimes offers savings cards or patient assistance programs for eligible individuals. Additionally, some non-profit organizations provide financial support for people living with epilepsy to help cover the costs of anti-seizure medications.
