Summary
Adding a second antiepileptic drug for intractable epilepsy with complex-partial seizures showed limited benefit. Most patients did not experience seizure reduction, and some even saw increased seizure frequency.
Area of Science:
- Neurology
- Clinical Pharmacology
Background:
- Intractable epilepsy with complex-partial seizures poses treatment challenges.
- Optimal one-drug therapy is often insufficient for managing difficult-to-treat epilepsy cases.
Purpose of the Study:
- To evaluate the efficacy of adding a second antiepileptic drug (AED) in adult patients with intractable epilepsy and complex-partial seizures.
- To assess the impact of dual AED therapy on seizure frequency following monotherapy failure.
Main Methods:
- A long-term prospective trial involving 30 adult patients with refractory epilepsy.
- Patients received a second AED chosen based on individual history, titrated to clinical toxicity if necessary.
Main Results:
- Only 13% of patients (4/30) achieved >75% seizure reduction with a second AED.
- 87% of patients (26/30) did not benefit, with three experiencing >100% increase in seizure frequency.
- Adverse effects and lack of efficacy limited the utility of add-on therapy.
Conclusions:
- The addition of a second antiepileptic drug in cases of intractable epilepsy with complex-partial seizures demonstrates limited efficacy.
- Current clinical practice of adding a second AED may require re-evaluation pending further evidence supporting its benefit over monotherapy.
