Abstract
Lacosamide, a voltage-gated sodium channel inhibitor, is an anti-seizure medication (ASM) from the age of 4. We report on the case of a woman treated with lacosamide for pharmacoresistant epilepsy who breastfed her infant for more than 6 months after birth. The infant's blood concentrations of lacosamide were 2.4 mg/L on Day 1 and less than 1 mg/L on Day 10 (reference values are 1-10 mg/L). No adverse drug reactions (ADRs) were reported for the infant. Eight cases of breastfeeding by mothers receiving lacosamide are described in the literature. These data confirm that a significant amount of lacosamide seems to pass into breast milk, with a relative infant dose (RID) above 20% in two cases but a low RID (1.8%) in another case. Nevertheless, blood tests, performed in two breastfed infants, revealed low concentrations of lacosamide. No ADRs were reported in eight of the breastfed infants; however, one infant, whose mother was also treated with levetiracetam, presented poor feeding and sleepiness at Day 15 of life. Given the well-known benefits of breastfeeding for both mothers and their infants, as well as the above reassuring data, breastfeeding of healthy full-term infants could be possible for mothers on lacosamide monotherapy. Nonetheless, relatives should be warned that data concerning the safety of lacosamide during breastfeeding are scarce and that long-term neurodevelopment outcomes in breastfed children are unknown. Clinical monitoring of breastfed infants for drowsiness, adequate weight gain, or cutaneous rash is recommended. Additionally, the infants' serum levels should be measured in case of an unexplained adverse reaction.

Abstract
OBJECTIVE In pregnancy, it is important to balance the risks of uncontrolled epileptic seizures to the mother and fetus against the potential teratogenic effects of antiseizure medications. Data are limited on pregnancy outcomes among patients taking lacosamide (LCM), particularly when taken as monotherapy. The objective of this analysis was to evaluate the pregnancy outcomes of LCM-exposed pregnancies. METHODS This analysis included all reports in the UCB Pharma pharmacovigilance database of exposure to LCM during pregnancy from spontaneous sources (routine clinical settings) or solicited reports from interventional clinical studies and noninterventional postmarketing studies. Prospective and retrospective reports were analyzed separately. RESULTS At the data cutoff (August 31, 2021), there were 202 prospective pregnancy cases with maternal exposure to LCM and known outcomes. Among these cases, 44 (21.8%) patients received LCM monotherapy and 158 (78.2%) received LCM polytherapy. Most patients received LCM during the first trimester (LCM monotherapy: 39 [88.6%]; LCM polytherapy: 143 [90.5%]). From the prospective pregnancy cases with maternal LCM exposure, there were 204 reported outcomes (two twin pregnancies occurred in the polytherapy group). The proportion of live births was 84.1% (37/44) in patients who received LCM as monotherapy, and 76.3% (122/160) for LCM polytherapy. The overall proportion of abortions (for any reason) was 15.9% (7/44) with LCM monotherapy, and 22.5% (36/160) with LCM polytherapy. Congenital malformations were reported in 2.3% (1/44) of known pregnancy outcomes with maternal exposure to LCM monotherapy, and 6.9% (11/160) with polytherapy. SIGNIFICANCE Our preliminary data do not raise major concerns on the use of LCM during pregnancy. Most pregnancies with LCM exposure resulted in healthy live births, and no new safety issues were identified. These findings should be interpreted with caution, as additional data are needed to fully evaluate the safety profile of LCM in pregnancy.

Abstract
Background: Third generation antiseizure medications (ASMs) are currently used for seizure control as well as several other indications, including pain management and psychiatric disorders. As a result, maternal exposure to third generation ASMs during pregnancy has become increasingly prevalent. The current systematic review aimed to summarize the published evidence on third generation ASMs and their effect on preterm birth, cesarean section (c-section) and fetal loss. Methods: The following databases were searched: Medline, Embase, International Pharmaceutical Abstracts, Cochrane Library and Scopus until September 2022. Results: We screened 2987 studies, and identified 32 studies or case reports for inclusion, however only one study utilized a control group. Narrative systematic evidence synthesis was conducted for brivaracetam, eslicarbazepine, fosphenytoin, lacosamide and perampanel. Conclusion: Due to the scarcity and quality of published studies, drawing clear-cut conclusions regarding third generation ASMs and the outcomes of interest is challenging. More comparative safety studies focusing on neonatal safety of third generation ASMs in pregnancy are essential.

Abstract
BACKGROUND Status epilepticus in pregnancy (SEP) is rare and life-threatening for both mother and fetus. There are well-established guidelines for the management of women with epilepsy during pregnancy; however, there is little evidence guiding the management of SEP, leading to uncertainty among treating physicians. Therefore, this survey aims to investigate the real-world practices of physicians treating SEP to explore management approaches for improvements in care. METHODS An anonymous, electronic survey was created and distributed to neurointensivists and neurologists between September and December 2021. RESULTS One hundred physicians initiated the survey and 95 completed it in full: 87 (87%, 87/100) identified neurology as their primary specialty, 31 had subspecialty training in neurocritical care, and 48 had subspecialty training in epilepsy and/or clinical neurophysiology. Over half of the survey respondents (67%, 67/100) reported having participated in the management of SEP, with 48.9% (49/98) having done so in the past year. Most survey respondents (73%, 73/100) reported that their management approach to SEP is different than that of non-pregnant patients. Survey respondents were more likely to involve epilepsy consultants when treating SEP (58.5%, 58/99) and the vast majority involved Obstetrics/Maternal Fetal Medicine consultants (90.8%, 89/98). Survey respondents showed a clear preference for levetiracetam (89.7%, 87/97) in the treatment of benzodiazepine refractory status epilepticus followed by lacosamide (61%, 60/98) if an additional second line agent was needed. Valproate and phenobarbital were unlikely to be used. There was less agreement for the management of refractory and super-refractory SEP. CONCLUSIONS Levetiracetam is the most frequently used anti-seizure medication (ASM) for benzodiazepine-refractory SEP. Survey participants tended to manage SEP differently than in non-pregnant patients including greater involvement of interdisciplinary teams as well as avoidance of ASMs associated with known teratogenicity.

Abstract
INTRODUCTION Lacosamide is licensed for the treatment of focal seizures in both adults and children, however there is little information available on its adverse reactions. Using the FDA Adverse Event Reporting System (FAERS), we seek to assess adverse occurrences that may be related to Lacosamide. METHODS On the basis of the FAERS database from the fourth quarter of 2008 to the second quarter of 2022, disproportionality analysis was carried out using the reporting odds ratio (ROR) method, the United Kingdom Medicines and Healthcare Products Regulatory Agency omnbius standard (MHRA) method, and the bayesian confidence propagation neural network (BCPNN) method. We extracted valuable positive signals for designated medical event (DME) screening, focused on the evaluation and comparison of safety signals appearing in DME with system organ classification (SOC) analysis. RESULTS A total of 10,226 adverse reaction reports with Lacosamide as the primary suspect drug were obtained, with 30,960 reported cases, detecting 232 valuable positive signals, involving a total of 20 SOCs, of which the most frequently reported SOCs were nervous system disorders (6537 cases, 55.21%), psychiatric disorders (1530 cases, 12.92%), injury poisoning and procedural complications (1059 cases, 8.94%). According to 232 valuable positive signals with DME screening results, two signals of stevens-johnson syndrome and ventricular fibrillation were consistent with PT signals on the DME list, with the two SOCs focusing on skin and subcutaneous tissue disorders and cardiac disorders, respectively. CONCLUSIONS Our research demonstrates that the clinical use of Lacosamide should be noticed and avoided in relation to ADRs since it raises the risk of cardiac arrest, ventricular fibrillation, stevens-johnson syndrome, and rhabdomyolysis.

Increasing use of newer antiseizure medication during pregnancy: An observational study with special focus on lacosamide. Seizure 2023; 107:107-113.

Abstract
INTRODUCTION Epilepsy is a common neurological disease requiring long-term therapy also during pregnancy. Most studies on pregnancy outcomes in women with epilepsy are based on antiseizure medication (ASM) in monotherapy. However, about 20-30% of epilepsy patients require polytherapy and newer ASMs are an option, when seizure control is not achieved with first line ASMs. METHODS Observational study evaluating the use of newer ASMs with marketing authorization since 2005 reported to the Embryotox Center of Clinical Teratology and Drug Safety in Pregnancy between 2004 and 2019. In addition, course and outcome of lacosamide exposed pregnancies were analysed. RESULTS Our study confirms the increasing use of newer ASMs also in pregnant women. This is especially true for lacosamide, eslicarbazepine and brivaracetam with rising numbers of exposed pregnancies soon after marketing authorization. Analysis of 55 prospectively and 10 retrospectively ascertained lacosamide exposed pregnancies does not indicate increased risks of major birth defects or spontaneous abortion. However, bradycardia observed in 3 neonates might be related to prenatal lacosamide exposure. CONCLUSION Available data do not support the assumption of lacosamide being a major teratogen. The increasing use of newer ASMs during pregnancy underscores the need for more studies to guide preconception counselling, especially for lacosamide, eslicarbazepine and brivaracetam.

Abstract
INTRODUCTION Given the high prevalence of epilepsy in women of childbearing potential (15 million out of 50 million people worldwide), antiseizure medication (ASM) use in pregnancy is common. Identifying the safest and most effective ASM to use during pregnancy is often difficult, but also crucially important. The challenge is to balance two needs: maintaining seizure control while minimizing teratogenicity. AREAS COVERED This review looks at seizure- and treatment-related risks to mother and fetus during pregnancy, existing healthcare information programmes, strengths and pitfalls of the main pregnancy registries, known and supposed pharmacokinetic changes during gestation, the utility of therapeutic drug monitoring, and safety concerns. Articles and related content were screened on available publications after January 2000. EXPERT OPINION The use of newer ASMs during pregnancy is still limited, as shown by the paucity of data collected by different pregnancy registries. Choosing these medications can be challenging, partly due to unknown pharmacokinetic modifications in pregnancy, an aspect that serum drug monitoring might help to clarify. The safest treatment is chosen also taking into account the woman's needs, concerns and wishes, but adequate pre-pregnancy counseling is necessary to properly inform her about personal and fetal risks related both to seizures and to medications.

Abstract
Epilepsy is a common neurological disease. At present, there are about 70 million epilepsy patients in the world, half of them are women, and 30–40% of women with epilepsy are of childbearing potential. Patients with epilepsy who are of childbearing potential face more challenges, such as seizures caused by hormonal fluctuations and the risk of adverse effects on the mother and baby from taking anti-seizure medications (ASMs). Breast milk is one of the best gifts that a mother can give her baby, and breastfeeding can bring more benefits to the baby. Compared with healthy people, people with epilepsy have more concerns about breastfeeding because they are worried that ASMs in their milk will affect the growth and development of the baby, and they are always faced with the dilemma of whether to breastfeed after childbirth. Regarding, whether women with epilepsy can breastfeed while taking ASMs, and whether breastfeeding will adversely affect the baby is still an important topic of concern for patients and doctors. This article reviews the existing research on breastfeeding-related issues in women with epilepsy to guide clinical practice, and improve the breastfeeding compliance of women with epilepsy.

Abstract
Lacosamide is a novel antiepileptic drug. Although many antiepileptic drugs reportedly pose a risk to fetuses, patients with epilepsy are advised to continue their medications during pregnancy. There have been few reports on lacosamide use during pregnancy, and its effects on the fetus remain unclear. Here, we report a case of lacosamide use during pregnancy. The 33-year-old patient was treated with oral lacosamide (400 mg/d) for symptomatic partial epilepsy. She was concomitantly treated with folic acid (5 mg/d) beginning 4 days before her last menstrual cycle. She was also concomitantly treated with oral perampanel (2 mg/d) at 5-7 weeks' gestation for seizure control but discontinued perampanel after the pregnancy was discovered. She progressed through her pregnancy with only mild seizures. Fetal growth was normal and ultrasonography revealed no external malformations. The patient had an elective cesarean section at 37 weeks and 2 days owing to a previous post-cesarean pregnancy. Her baby boy weighed 3025 g; his Apgar score was 8 and 9, 1 and 5 min, respectively, and his umbilical artery blood pH was 7.348. He had no congenital anomalies and no neonatal drug withdrawal symptoms. This suggests that lacosamide may have a low risk of teratogenicity and fetal toxicity. Thus, this case is valuable for clinicians who are considering the administration of antiepileptic drugs during pregnancy. In the future, more reports on the use of lacosamide during pregnancy should be collected.

Abstract
Women with epilepsy (WWE) wishing for a child represent a highly relevant subgroup of epilepsy patients. The treating epileptologist needs to delineate the epilepsy syndrome and choose the appropriate anti-seizure medication (ASM) considering the main goal of seizure freedom, teratogenic risks, changes in drug metabolism during pregnancy and postpartum, demanding for up-titration during and down-titration after pregnancy. Folic acid or vitamin K supplements and breastfeeding are also discussed in this review. Lamotrigine and levetiracetam have the lowest teratogenic potential. Data on teratogenic risks are also favorable for oxcarbazepine, whereas topiramate tends to have an unfavorable profile. Valproate needs special emphasis. It is most effective in generalized seizures but should be avoided whenever possible due to its teratogenic effects and the negative impact on neuropsychological development of in utero-exposed children. Valproate still has its justification in patients not achieving seizure freedom with other ASMs or if a woman decides to or cannot become pregnant for any reason. When valproate is the most appropriate treatment option, the patient and caregiver must be fully informed of the risks associated with its use during pregnancies. Folate supplementation is recommended to reduce the risk of major congenital malformations. However, there is insufficient information to address the optimal dose and it is unclear whether higher doses offer greater protection. There is currently no general recommendation for a peripartum vitamin K prophylaxis. During pregnancy most ASMs (e.g. lamotrigine, oxcarbazepine, and levetiracetam) need to be increased to compensate for the decline in serum levels; exceptions are valproate and carbamazepine. Postpartum, baseline levels are reached relatively fast, and down-titration is performed empirically. Many ASMs in monotherapy are (moderately) safe for breastfeeding and women should be encouraged to do so. This review provides a practically oriented overview of the complex management of WWE before, during, and after pregnancy.

Abstract
INTRODUCTION Status epilepticus (SE) in pregnancy represents a life-threatening medical emergency for both mother and fetus. Pregnancy-related pharmacokinetic modifications and the risks for fetus associated with the use of antiseizure medications (ASMs) and anesthetic drugs complicate SE management. No standardized treatment protocol for SE in pregnancy is available to date. AREAS COVERED In this review, we provide an overview of the current literature on the management of SE in pregnancy and we propose a multidisciplinary-based protocol approach. EXPERT OPINION Literature data are scarce (mainly anecdotal case reports or small case series). Prompt treatment of SE during pregnancy is paramount and a multidisciplinary team is needed. Benzodiazepines are the drugs of choice for SE in pregnancy. Levetiracetam and phenytoin represent the most suitable second-line agents. Valproic acid should be administered only if other ASMs failed and preferably avoided in the first trimester of pregnancy. For refractory SE, anesthetic drugs are needed, with propofol and midazolam as preferred drugs. Magnesium sulfate is the first-line treatment for SE in eclampsia. Termination of pregnancy, via delivery or abortion, is recommended in case of failure of general anesthetics. Further studies are needed to identify the safest and most effective treatment protocol.

PURPOSE OF REVIEW Issues pertaining to women with epilepsy have advanced with a better understanding of multidirectional influences among hormones, seizures, and antiseizure medications, as well as pregnancy-related concerns around fertility, seizure destabilization, and antiseizure medication-associated teratogenicity. This article highlights important developments in this field and reviews best practices in the management of women with epilepsy. RECENT FINDINGS Important external hormonal influences may impact women with epilepsy particularly in the context of gender-affirming medications, hormonal replacement therapy, and fertility therapies. Fertility for women with epilepsy is influenced by multiple variables; however, in the absence of preexisting fertility issues, epilepsy per se is not associated with significantly impaired fertility. Once women with epilepsy are pregnant, the majority have a stable course. Antiseizure medication use in pregnancy is associated with major congenital malformations 2 to 5 times that of the general population and is highest with high-dose (≥1500 mg or greater total daily) valproate. Carefully considered changes in drug choice and dose may mitigate these risks. Therapeutic drug monitoring plays an important role in pregnancy care, and under expert supervision, women with epilepsy in pregnancy have similar seizure risks as women with epilepsy who are not pregnant. As women with epilepsy age, bone health and menopause may further be impacted by seizures and antiseizure medications. SUMMARY The care of women with epilepsy is a multifaceted discipline that recognizes the life-long impact of sex and gender influences on epilepsy care.

Yang C, Peng Y, Zhang L, Zhao L. Safety and Tolerability of Lacosamide in Patients With Epilepsy: A Systematic Review and Meta-Analysis. Front Pharmacol 2021; 12:694381. [PMID: 34616294 PMCID: PMC8488108 DOI: 10.3389/fphar.2021.694381] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 08/23/2021] [Indexed: 01/03/2023] Open
Abstract
Background: As a third-generation antiseizure medication (ASM), lacosamide (LCM) is recommended worldwide for patients with epilepsy. We aimed to provide more conclusive evidence for the safety and tolerability of LCM in patients with epilepsy. Methods: A systematic search was performed on MEDLINE, Embase, Cochrane Library, CBM, CNKI, IDB, VIP Database, and Wanfang Database from inception to 2021 March, and all studies assessing the safety of LCM were included. A meta-analysis was performed for safety data of LCM. Results: Eighty-three studies involving 12268 populations (11 randomized clinical trials (RCTs), 16 cohort studies, 53 case series, and 3 case reports) were included in our study. Meta-analysis of the total incidence of adverse events (AEs) of LCM was 38.7% [95% CI (35.1%, 45.8%); n=75 studies]. Incidence of withdrawal due to AEs was 10.8% [95% CI (9.1%, 12.6%); n=56 studies], and incidence of serious adverse events (SAEs) was 6.5% [95% CI (4.0%, 8.9%); n=13 studies]. Most AEs were in the nervous system and digestive system. The most common AEs were sedation (15.8%), dizziness (15.7%), fatigue (9.4%), and nausea/vomiting (9.3%). For children, the total incidence of AEs of LCM was 32.8% [95% CI (21.6%, 44.0%); n=16 studies], and the most common AEs were dizziness (8.6%), nausea/vomiting (8.6%), and somnolence (6.8%). Conclusion: Lacosamide is generally safe and well tolerated in patients with epilepsy. Common AEs were sedation, dizziness, and fatigue. It is necessary to pay more attention to the prevention and management of these AEs and conduct more large-scale and high-quality studies to update safety data.

Abstract
Still considered a new ASD, teratogenicity from lacosamide (LCM) exposure during pregnancy is unknown. LCM metabolism through several cytochrome P450 enzymes and minor glucuronidation metabolism in the liver may increase during pregnancy and theoretically lead to lower LCM levels during pregnancy and the risk of increased seizures. Our objective was to determine the impact of pregnancy on serum LCM levels in a series of women with epilepsy (WWE). We identified seven pregnancies with exposure to LCM with at least one level drawn during pregnancy. Patient ages ranged from 18 to 38 years (mean 26.4 years) and total daily doses of LCM ranged from 200 to 600 mg/day. Two patients had increased dose adjustments in response to breakthrough seizures. Dose normalized concentrations (DNC) showed an overall decrease over time through each trimester (p = 0.002) and significantly lower during trimester 2 and 3 (p = 0.001 and p = 0.004, respectively) compared to pre-pregnancy levels. There were no significant changes in seizure frequency and none of the neonates had teratogenic findings at time of birth. We are the first to report a case series on the changes in LCM levels during pregnancy with significant decreased LCM DNC levels during the second and third trimesters in comparison to pre-pregnancy values.

Abstract
Epilepsy is one of the most common brain disorders, affecting more than 50 million people worldwide. Although its treatment is currently symptomatic, the last generation of anti-seizure drugs is characterized by better pharmacokinetic profiles, efficacy, tolerability and safety. Lacosamide is a third-generation anti-seizure drug that stands out due to its good efficacy and safety profile. It is used with effectiveness in the treatment of partial-onset seizures with or without secondary generalization, primary generalized tonic-clonic seizures and off-label in status epilepticus. Despite scarcely performed until today, therapeutic drug monitoring of lacosamide is proving to be advantageous by allowing the control of inter and intra-individual variability and promoting a successful personalized therapy, particularly in special populations. Herein, the pharmacology, pharmacokinetics, and clinical data of lacosamide were reviewed, giving special emphasis to the latest molecular investigations underlying its mechanism of action and therapeutic applications in pathologies besides epilepsy. In addition, the pharmacokinetic characteristics of lacosamide were updated, as well as current literature concerning the high pharmacokinetic variability observed in special patient populations and that must be considered during treatment individualization.

Abstract
Tumors of the central nervous system (CNS) are rare entities, typically affecting the very young or the very old, but span a spectrum of disease that may present in any age group. Women of reproductive age are more likely to be affected by benign tumors, including pituitary adenomas and meningiomas, and aggressive intracranial malignancies, such as brain metastases and glioblastoma, rarely present in pregnancy. Definitive management of CNS tumors may involve multimodal therapy, including surgery, radiation, and chemotherapy, and each of these treatments carries risk to the mother and developing fetus. CNS tumors often present with challenging and morbid symptoms such as headache and seizure, which need to be managed throughout a pregnancy. Decisions about timing treatment during pregnancy or delaying until after delivery, continuing or electively terminating a pregnancy, and future family planning and fertility are complex and require a multidisciplinary care team to evaluate the implications to both mother and baby. There are no guidelines or consensus recommendations regarding brain tumor management in pregnancy, and thus, individual treatment decisions are made by the care team based on experiential evidence, extrapolation of guidelines for nonpregnant patients, and patient values and preferences.

Abstract
In the context of local culture and misconceptions regarding epilepsy, Saudi practitioners need a careful management plan for women with epilepsy that satisfies all the patients’ needs and ensures their spouses’ understanding. Such a management strategy needs to incorporate careful selection and monitoring of anti-epileptic drugs and regular counseling of patients. Female epileptic patients in the reproductive age group, no matter whether they are pregnant or not, should be managed by safest drugs from the earliest with folic acid supplementation along with adequate pre-marriage/conception counseling. All antiepileptic drugs are potentially teratogenic. However, valproic acid, phenytoin, phenobarbitone, and topiramate are least favored for use. Monotherapy is preferred over polytherapy, and the least possible dose should be used. During pregnancy, many epileptic women may need monthly drug level monitoring and dose readjustments. Normal vaginal delivery is safe in epileptic women. Post-partum follow-up with anti-epileptic drug titration may be required.

Abstract
Inhibition of histone deacetylases (HDACs) and subsequent hyperacetylation of histone proteins lead to altered gene expression associated with therapeutic drug effects, but also with teratogenicity. The only US Food and Drug Administration (FDA)-approved antiepileptic drug that has been consistently shown to induce histone hyperacetylation is valproic acid. More recently, lacosamide was reported to interfere with histone modifications, but histone hyperacetylation was not demonstrated. In the current study we evaluated the effects of lacosamide on histone acetylation in vitro. MDA-MB-231 (triple-negative breast cancer) cells and human placental BeWo cells were exposed for 16 hours to 5-20 μg/ml (20-80 μm) lacosamide. Histone acetylation was evaluated by western blot analysis. We additionally measured HDAC1 activity in the presence of lacosamide. At 5, 10, and 20 μg/ml, lacosamide enhanced histone acetylation in BeWo cells by 1.7-fold (p > 0.05), 3.4-fold (p < 0.05), and 3.0-fold (p > 0.05), respectively. Histone H3 acetylation and total histones H3 and H4 levels were not significantly modified (p > 0.05). The magnitude of change in histone acetylation in MDA-MB-231 cells was smaller (p > 0.05). In contrast to valproic acid, lacosamide did not inhibit HDAC1. Our findings suggest that the effects of lacosamide on gene expression, and the related potential antitumor activity and teratogenicity, may differ from those of valproic acid.

Abstract
INTRODUCTION Up to 30% of the patients diagnosed with epilepsy will continue suffering from seizures despite treatment with antiepileptic drugs, either in monotherapy or polytherapy. Hence, there remains the need to develop new effective and well-tolerated therapies. AIM The objective of this article was to review the evidence for the efficacy and safety of eslicarbazepine acetate (ESL) as adjunctive treatment in adult patients with focal onset seizures. EVIDENCE REVIEW ESL is the newest, third-generation, single enantiomer member of the dibenzazepine family. Following oral administration, ESL is rapidly and extensively metabolized by hepatic first-pass hydrolysis to the active metabolite eslicarbazepine, which has linear, dose-proportional pharmacokinetics and low potential for drug-drug interactions. Eslicarbazepine works as a competitive blocker of the voltage gated sodium channels; unlike carbamazepine (CBZ) and oxcarbazepine (OXC), it has a lower affinity for the resting state of the channels, and reduces their availability by selectively enhancing slow inactivation. Efficacy and safety of ESL have been assessed in four randomized, Phase III clinical trials: the median relative reduction in standardized seizure frequency was 33.4% and 37.8% in the ESL 800 and 1,200 mg daily dose groups, and the responder rates were 33.8% and 43.1%, respectively. The incidence of treatment-emergent adverse events (TEAEs) increased with raising the dosage (ESL 400 mg: 63.8%, ESL 800 mg: 67.0%, ESL 1,200 mg: 73.1%). The TEAEs were generally mild to moderate in intensity, and the most common were dizziness, somnolence, headache and nausea. Open-label studies confirmed the findings from the pivotal trials and demonstrated sustained therapeutic effect of ESL over time and improvement of tolerability profile in patients switching from OXC/CBZ. No unexpected safety signals emerged over >5 years of follow-up. CONCLUSION Once-daily adjunctive ESL at the doses of 800 and 1,200 mg was effective to reduce the seizure frequency and was fairly well tolerated in adults with focal onset epilepsy. Starting treatment at 400 mg/day, followed by 400 mg increments every 7-14 days, could provide the optimal balance of efficacy and tolerability.

Abstract
BACKGROUND In the treatment of pediatric epilepsy, there is a critical demand for effective and safe therapeutic options to address patients' unmet clinical needs. Eslicarbazepine acetate is a novel once-daily antiepileptic drug and a third-generation single enantiomer member of the dibenzazepine family. OBJECTIVE The objective of this study was to evaluate the efficacy and safety of eslicarbazepine acetate as add-on treatment for focal-onset seizures in pediatric patients using meta-analytical techniques. METHODS Randomized, placebo-controlled, single- or double-blinded add-on trials of eslicarbazepine acetate in patients < 18 years of age with focal-onset seizures uncontrolled by concomitant stable antiepileptic drug regimens were identified through a systematic literature search. The assessed outcomes included the mean relative change and ≥ 50% reduction in the baseline seizure frequency, the incidence of treatment withdrawal, serious adverse events, and treatment-emergent adverse events. Risk ratio and weighted mean difference with 95% confidence intervals were estimated for dichotomous/continuous outcomes. RESULTS Two trials were included involving 386 participants (age range 2-18 years), 217 for eslicarbazepine acetate and 169 for placebo groups, respectively. At the dosage of 30 mg/kg/day, eslicarbazepine acetate-treated patients had a significantly greater reduction in baseline seizure frequency (weighted mean difference - 21.67, 95% confidence interval - 40.87 to - 2.46; p = 0.027) and 58 patients (44.6%) were seizure responders compared with 27 controls (29.7%) [risk ratio 1.48, 95% confidence interval 0.99-2.20; p = 0.055]. There were no differences in treatment withdrawal (risk ratio 1.24, 95% confidence interval 0.65-2.37; p = 0.513), serious adverse events (risk ratio 1.40, 95% confidence interval 0.69-2.86; p = 0.350), and treatment-emergent adverse events (risk ratio 1.07, 95% confidence interval 0.94-1.22; p = 0.313). CONCLUSIONS Adjunctive eslicarbazepine acetate could be an effective well-tolerated option in children and adolescents with focal-onset seizures uncontrolled by one or more concomitant anti-epileptic drugs.

Abstract
OBJECTIVE The aim of the study was to assess the clinical response to eslicarbazepine acetate (ESL) as add-on therapy in adult patients with partial-onset epilepsy by means of the time-to-baseline seizure count method. METHODS We retrospectively identified consecutive patients with partial-onset seizures, with or without secondary generalization, prescribed to ESL add-on therapy. The primary endpoint was the time-to-baseline monthly seizure count. Subgroup analysis was performed according to carbamazepine (CBZ)/oxcarbazepine (OXC) status (prior vs never use). Secondary outcomes were the rate of treatment-related adverse events (AEs) and the AEs affecting ≥5% of patients. RESULTS One-hundred and eighteen patients were included. The median time-to-baseline monthly seizure count was 46 (35-101) days in the overall study cohort. The number of concomitant anti-epileptic drugs (AEDs) was associated with the time-to-endpoint (adjusted hazard ratio [adj HR]=2.22, 95% CI 1.18-4.14, P=.013 for two AEDs vs one; adj HR=3.65, 95% CI 1.66-8.06, P=.001 for three or more AEDs vs one). Groupwise, the median times-to-baseline seizure count were 47 (35-97) and 43 (34-103) in patients with prior and never exposure to CBZ/OXC, respectively (P for log-rank test=.807). Adverse events occurred in 53.4% (63 of 118) of patients; the most frequently reported were dizziness (13.6%), somnolence (11.9%), nausea (6.8%), and fatigue (5.1%). CONCLUSIONS Add-on ESL improved seizure control and was overall well-tolerated in adult patients with partial-onset epilepsy.
