How Does Aptiom Affect Seizure Activity?

Eslicarbazepine acetate is converted extensively to eslicarbazepine after dosing. The exact anticonvulsant mechanism is not known, but eslicarbazepine is thought to inhibit voltage-gated sodium channels. Reducing sodium channel activity can limit repetitive firing of neurons involved in partial-onset seizures.

Who Can Be Treated With Aptiom?

Aptiom is approved for partial-onset seizures in adults and children age 4 and older. It can be used as monotherapy or together with other antiseizure medicines. Pediatric dosing is based on body weight. Safety and efficacy have not been established for children younger than 4.

How Are Aptiom Tablets Dosed?

Adults commonly start at 400 mg once daily and increase at weekly intervals to a maintenance dose of 800 mg to 1600 mg once daily. Pediatric dosing is weight based. Moderate or severe kidney impairment requires a 50 percent dose reduction. Tablets can be swallowed whole or crushed and taken with or without food.

Which Reactions Need Medical Attention With Aptiom?

Serious risks include suicidal thoughts or behavior, severe skin reactions, DRESS, anaphylaxis, angioedema, low blood sodium, neurologic problems, liver injury, and blood disorders. Dizziness, sleepiness, nausea, headache, double vision, vomiting, fatigue, vertigo, poor coordination, blurred vision, and tremor are common. Aptiom is withdrawn gradually to reduce increased seizure frequency and status epilepticus risk.
