Input: We included five trials (1799 participants) rated at low risk of bias apart from a high risk of attrition bias; all studies were funded by BIAL. The overall risk ratio (RR) with 95% confidence interval (CI) for 50% or greater reduction in seizure frequency was 1.71 (95% CI 1.42 to 2.05). Dose regression analysis showed evidence that ESL reduced seizure frequency with an increase in efficacy with increasing doses of ESL. ESL was significantly associated with seizure freedom (RR 2.90, 95% CI 1.49 to 5.68). Participants were more likely to have ESL withdrawn for adverse effects (RR 2.66, 95% CI 1.42 to 4.96) but not for any reason (RR 1.19, 95% CI 0.86 to 1.64). The following adverse effects were significantly associated with ESL: dizziness (RR 2.81, 99% CI 1.86 to 4.27); nausea (RR 2.61, 99% CI 1.36 to 5.01); diplopia (RR 4.14, 99% CI 1.74 to 9.84); somnolence (RR 1.71, 99% CI 1.11 to 2.63) and vomiting (RR 3.30, 99% CI 1.34 to 8.13). Overall the quality of the evidence was rated as moderate due to a high discontinuation rate. ESL reduces seizure frequency when used as an add-on treatment for people with drug-resistant focal epilepsy. The trials included in this review were of short-term duration and focused on adults. One new trial has been included in this update, but the conclusions are unchanged.
Output:

The evidence is current to December 2016. We included five clinical trials with 1799 participants aged 16 to 77 years. The included studies had different treatment periods of 12 to 14 weeks. All five trials were randomized controlled trials, which means that people were randomly divided into groups and compared. This review found that eslicarbazepine acetate was effective when used in combination with other medicines to reduce the number of seizures in drug-resistant focal epilepsy. People who took eslicarbazepine acetate were more likely to have no seizures than people who took the placebo (a pretend tablet), but they were more likely to withdraw from eslicarbazepine acetate treatment because of side effects. Side effects associated with eslicarbazepine acetate were dizziness, nausea (feeling sick), somnolence (feeling sleepy), vomiting (being sick) and diplopia (having double vision). Altogether the five trials used good methods, but information was missing from the trials for between 10% and 45% of people taking each medicine in each trial. This missing information may have introduced uncertainty into results so the evidence in this review is of moderate quality. More research is needed to look at the long-term effects of eslicarbazepine acetate and to explore how well it works in children with epilepsy.
