Aptiom

Treatment of Partial-Onset Seizures

Aptiom is primarily prescribed to manage partial-onset seizures, which are seizures that begin in a specific area of the brain. It is approved for use in both adults and children who are at least 4 years old.

How It Is Used

Depending on the patient's specific needs and medical history, healthcare providers may prescribe Aptiom in the following ways:

• Monotherapy: The medication is used alone as the sole treatment for seizure control.
• Adjunctive therapy: The medication is used in combination with other anti-epileptic drugs to help manage seizures that are not well-controlled by a single medication.

Aptiom belongs to a class of drugs known as anticonvulsants or antiepileptics. While it helps control and reduce the frequency of seizures, it is not a cure for epilepsy and must be taken consistently as directed by a healthcare professional to be effective.

How Aptiom Affects the Brain

Aptiom is an anticonvulsant medication used to manage partial-onset seizures. It works by influencing the electrical activity within the brain's nerve cells, also known as neurons.

Targeting Sodium Channels

The primary way Aptiom is thought to work is by blocking voltage-gated sodium channels. These channels act as gates that control the flow of electrical impulses between neurons. During a seizure, these channels may stay open too long or fire too frequently, leading to a burst of uncontrolled electrical activity.

By interacting with these channels, Aptiom helps to:

• Limit repetitive firing: It prevents neurons from sending rapid, excessive electrical signals.
• Stabilize nerve membranes: It makes the nerve cells less likely to become over-excited.
• Control seizure spread: It helps contain abnormal electrical activity so it does not spread as easily to other areas of the brain.

Although the precise mechanism is not completely established, these actions collectively help reduce the frequency of seizure episodes in patients with epilepsy.

Common Side Effects

The most frequently reported side effects of Aptiom include:

• Dizziness and vertigo
• Drowsiness or fatigue
• Nausea and vomiting
• Headache
• Blurred or double vision
• Tremor or loss of coordination

Serious Side Effects

Some side effects can be severe and may require urgent medical care. Contact a healthcare provider immediately if you experience:

• Low sodium levels: This condition, known as hyponatremia, can cause confusion, tiredness, nausea, or more frequent seizures.
• Serious skin rashes: Rare but life-threatening skin reactions can occur. Symptoms include a rash, hives, sores in the mouth, or peeling skin.
• Mood and behavior changes: This includes new or worsening depression, anxiety, panic attacks, or thoughts about self-harm.
• Liver injury: Symptoms may include yellowing of the skin or eyes, dark urine, or severe stomach pain.
• Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): This is a serious allergic reaction that can affect internal organs and typically presents with a fever and rash.

Suicidal Thoughts and Behavior

Antiepileptic drugs, including Aptiom, may increase the risk of suicidal thoughts or actions in a small number of people. It is important to monitor for new or worsening depression, anxiety, or any unusual changes in mood or behavior.

Serious Skin Reactions

Aptiom can cause rare but life-threatening skin reactions, such as Stevens-Johnson Syndrome (SJS) or Toxic Epidermal Necrolysis (TEN). These conditions require immediate medical attention. The medication is typically discontinued if a skin rash develops during treatment.

Low Sodium Levels

This medication may cause hyponatremia, a condition where sodium levels in the blood become too low. Symptoms can include nausea, headache, confusion, or increased seizures. Sodium levels may need to be checked periodically, especially for those taking other medications that affect sodium.

Allergic Reactions

Serious allergic reactions, including swelling of the face, lips, or throat (angioedema), can occur. Some patients may experience a condition called DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms), which can affect the liver, kidneys, or heart.

Neurological Impairment

Aptiom often causes dizziness, sleepiness, and problems with coordination or vision. These side effects are most common when starting the drug or increasing the dose. Caution is advised when driving or operating heavy machinery until the effects of the medication are known.

Liver and Blood Health

Rare cases of liver injury and low white blood cell or platelet counts have been reported. Monitoring of liver function and blood counts may be necessary for some patients.

Withdrawal Seizures

Stopping Aptiom suddenly can lead to an increase in seizure frequency or status epilepticus. The dose is usually reduced gradually under medical supervision.

Pregnancy

There is limited data regarding the use of Aptiom in pregnant women. In animal studies, the medication has shown the potential to cause developmental harm to the fetus. However, it is important to note that uncontrolled seizures during pregnancy can also pose serious risks to both the mother and the baby.

Healthcare providers typically evaluate the necessity of the medication on an individual basis. If you are pregnant or planning to become pregnant, discuss your treatment plan with your doctor. Do not stop taking seizure medication without medical supervision, as sudden discontinuation can lead to breakthrough seizures. Patients are often encouraged to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry to help monitor the safety of the drug during pregnancy.

Contraception

Aptiom can interact with hormonal contraceptives, such as birth control pills, patches, implants, or injections, making them less effective. This may increase the risk of an unintended pregnancy. It is generally recommended to use a non-hormonal form of birth control while taking this medication.

Breastfeeding

Aptiom passes into human breast milk. The effects of the drug on a nursing infant or on milk production are not currently well-understood. Because of the potential for side effects in the infant, a decision should be made whether to stop nursing or stop the medication, taking into account the mother's clinical need for the drug.

Dosage Forms

Aptiom is supplied as a tablet for oral administration. It is intended to be taken once daily.

The tablets may be swallowed whole or crushed. They can be taken with or without food.

FDA Approval Status

Aptiom (eslicarbazepine acetate) was first approved by the U.S. Food and Drug Administration (FDA) in November 2013. It is currently approved for the treatment of partial-onset seizures in patients 4 years of age and older. The medication can be used as monotherapy (on its own) or as adjunctive therapy (in combination with other medications).

Regulatory Classification

Aptiom is a prescription medication but is not classified as a controlled substance. It is available only by prescription from a licensed healthcare provider.

Safety Communications and Warnings

The FDA requires specific warnings for Aptiom, which are common to the class of antiepileptic drugs. These include:

• Suicidal Thoughts and Behavior: Monitoring is required for any new or worsening depression, suicidal thoughts, or unusual changes in mood.
• Serious Dermatologic Reactions: Rare but serious skin reactions, such as Stevens-Johnson syndrome, have been reported. Treatment should be discontinued at the first sign of a rash unless the rash is clearly not drug-related.
• Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): This is a serious hypersensitivity reaction that can affect multiple organs.
• Liver Injury: Healthcare providers may monitor liver function, as rare cases of drug-induced liver injury have occurred.

Risks of Abrupt Withdrawal

Stopping Aptiom suddenly can cause serious medical issues. Like many other seizure medications, abrupt discontinuation may lead to an increase in the frequency of seizures. In some instances, this can result in status epilepticus, a severe and potentially life-threatening condition where seizures last for a long time or occur so close together that the person does not recover between them.

Gradual Dose Reduction

To avoid withdrawal-related complications, healthcare providers usually recommend tapering the dose of Aptiom gradually. This process involves slowly reducing the amount of medication taken over a period of time, allowing the body to adjust. The length of the tapering period varies depending on the individual's medical history and the dosage they were taking.

Medical Supervision

It is important to follow a doctor's instructions exactly when stopping this medication. Do not skip doses or stop taking Aptiom even if you feel well, unless directed by a healthcare professional. If you experience any changes in seizure patterns or other concerning symptoms while reducing the dose, contact your doctor immediately.
