From the Guidelines
The treatment for symptoms of partial seizures when the diagnosis is confirmed primarily involves antiepileptic drugs (AEDs), with carbamazepine or oxcarbazepine being the preferred initial treatment options, at doses of 50-200 mg/day and 75-300 mg/day, respectively. When considering treatment for partial seizures, it's crucial to prioritize medications that have shown efficacy in reducing seizure frequency and improving quality of life.
- The choice of AED should be individualized, taking into account the patient's specific needs, potential side effects, and the likelihood of achieving complete or partial remission of symptoms.
- According to the study by 1, more than 85% of patients can achieve complete remission with low-dose carbamazepine or oxcarbazepine, and approximately 10% of patients can achieve partial control.
- It's essential to start with a low dose and gradually titrate upwards to minimize adverse effects, such as dizziness, which can be mitigated by taking the medication at bedtime.
- For patients who cannot tolerate carbamazepine or have a high risk of adverse cutaneous reactions, such as those with HLA-B*15:02, alternative AEDs like lamotrigine, topiramate, or phenytoin sodium may be considered as second-line treatment options, as recommended by 1.
- Regular follow-up appointments and open communication with the patient about the prognosis, potential side effects, and expected treatment outcomes are vital for ensuring optimal management of partial seizures.
From the FDA Drug Label
The effectiveness of monotherapy with lamotrigine was established in a multicenter, double-blind clinical trial enrolling 156 adult outpatients with partial-onset seizures The primary efficacy variable was the proportion of patients in each treatment group who met escape criteria. The percentages of patients who met escape criteria were 42% (32/76) in the group receiving lamotrigine and 69% (55/80) in the valproate group.
The treatment for symptoms of partial seizures when the diagnosis is confirmed is lamotrigine (PO), which has been shown to be effective in reducing seizure frequency in adults with partial-onset seizures 2.
- Monotherapy: Lamotrigine can be used as monotherapy for the treatment of partial-onset seizures.
- Adjunctive therapy: Lamotrigine can also be used as adjunctive therapy in combination with other antiepileptic drugs (AEDs) for the treatment of partial-onset seizures.
From the Research
Treatment for Symptoms of Partial Seizures
The treatment for symptoms of partial seizures typically involves the use of antiepileptic drugs, with the goal of controlling seizures and minimizing adverse effects.
- The choice of antiepileptic drug depends on various factors, including the type and severity of seizures, as well as the individual patient's response to treatment 3, 4, 5.
- Carbamazepine and valproic acid are commonly used as first-line treatments for partial seizures in adults and children 3, 6.
- Other antiepileptic drugs, such as levetiracetam, oxcarbazepine, topiramate, gabapentin, and lamotrigine, may also be effective as adjunctive or monotherapy treatments 5, 6.
- In some cases, surgical treatment may be considered for patients with intractable partial epilepsy 7.
- Nonpharmacological treatments, such as the ketogenic diet and vagus nerve stimulation, may also be useful as adjunctive alternative treatments for refractory partial seizures 6.
Considerations for Treatment
When treating partial seizures, it is essential to:
- Individualize treatment based on the patient's specific needs and response to treatment 4.
- Monitor serum levels of antiepileptic drugs to optimize dosing and minimize adverse effects 4.
- Consider the potential for adverse effects, such as weight gain, hair loss, and tremor, associated with certain antiepileptic drugs 3.
- Address psychosocial problems associated with epilepsy, as these can impact seizure control and overall quality of life 4, 7.
