Pharmacotherapy of focal epilepsy.

Abstract

INTRODUCTION:

Epilepsy is the most common neurological condition worldwide with significant psychosocial and physical morbidity. Its management requires expertise and good pharmacological knowledge of the available options.

AREAS COVERED:

This review covers the management of focal epilepsy addressing the common questions arising through the patients' journey, including timing of starting initial treatment, monotherapy options, add-on treatment for refractory cases and withdrawal of medication during remission.

EXPERT OPINION:

Initiating anti-epileptic drug (AED) treatment requires assessment of patient preferences and of evidence of benefit and harm. Evidence of benefit will come primarily from randomised controlled trials, although in epilepsy, most trials are undertaken to inform regulatory decision and have important limitations for informing clinical decisions. Evidence about harm may come not only from randomised trials but also from other sources. Most patients will start treatment following a second focal seizure. Carbamazepine and lamotrigine are good initial monotherapy options. Newer AEDs have proof of efficacy as monotherapy but evidence is insufficient to recommend them as first-line treatments. For refractory cases, there are an increasing number of AEDs available, but evidence of efficacy is primarily from placebo-controlled trials, and there is no robust evidence to inform a choice among treatments.
