Chen YS, Lai MC, Chen TS, Tseng YH, Li YJ, Huang CW. Effectiveness and Safety of Lacosamide, A Third-generation Anti-seizure Medication, for Poststroke Seizure and Epilepsy: A Literature Review. Curr Neuropharmacol 2023; 21:2126-2133. [PMID: 37340744 PMCID: PMC10556369 DOI: 10.2174/1570159x21666230616114255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 12/07/2022] [Accepted: 12/12/2022] [Indexed: 06/17/2023] Open
Abstract
Advances in stroke treatment have resulted in a dramatic reduction in stroke mortality. Nevertheless, poststroke seizures and epilepsy are issues of clinical importance affecting survivors. Additionally, stroke is the most common cause of epilepsy in older adults. Although numerous antiseizure medications exist, studies are needed to provide robust evidence of the efficacy and tolerability of these medicines for treating poststroke seizures and epilepsy. Crucially, the newer generations of antiseizure medications require testing. Lacosamide, a third-generation antiseizure medication approved for treating localization-related epilepsy, has a novel mechanism of selectively enhancing the slow inactivation of sodium channels. This literature review evaluated whether lacosamide is effective and safe for the treatment of poststroke seizures and epilepsy. This review critically analyzed studies published in major academic databases (Pubmed, Embase, and Cochrane Library) from inception through June 2022 regarding the interaction of lacosamide with poststroke seizures and epilepsy. We included clinical prospective, retrospective, and case studies on patients with poststroke seizure and epilepsy, lacosamide as a treatment for seizures, neuroprotection in animal models of seizures, and the safety of lacosamide when coadministering anticoagulants. Clinical studies revealed lacosamide to be an effective antiseizure medication with high efficacy and tolerability in patients with poststroke seizures and epilepsy. In animal models, lacosamide proved effective at seizure reduction and neuroprotection. Pharmacokinetic studies demonstrated the safety of lacosamide when coadministering conventional and new anticoagulants. The literature suggests that Lacosamide is a promising candidate antiseizure medication for patients with poststroke seizures and epilepsy.

[PMID: 35078115 DOI: 10.1016/j.yebeh.2022.108558] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 01/02/2022] [Accepted: 01/03/2022] [Indexed: 11/27/2022]
Abstract
OBJECTIVE Evaluate electroencephalographic changes in patients receiving purified pharmaceutical cannabidiol (CBD). METHODS A total of 104 EEG studies from 52 patients with pediatric-onset refractory epilepsy, who were enrolled in the FDA-approved expanded access investigational new drug program, were retrospectively analyzed for electroencephalographic changes in the background, interictal epileptiform discharges (IEDs), ictal findings, and sleep architecture after CBD treatment. RESULTS Patients were between 18 months and 52 years of age. After CBD treatment, 88.4% (46/52) of patients had EEG changes. Eighty-nine percent of these patients had changes in their background, 74% in IEDs, 46% in ictal findings, and 17% in sleep architecture. Seven out of 52 patients had modified hypsarrhythmia on their pre-treatment EEG. The pattern resolved in 2/7 patients (29%), diminished in prevalence in 4/7 (57%) subjects, and remained unchanged in 1/7 (14%) cases. Electrographic improvement was seen in 70% (32/46) of the patients, and worsening in 7% (3/46) of the cases. At the post-CBD EEG, 83% had a reduction in the frequency of the most predominant seizure type, and 25% reported subjective cognitive improvement. Of these patients, 88% (p = 0.09) and 92% (p = 0.45) had corresponding EEG changes, respectively. CONCLUSION Our results revealed electrographic changes in association with the CBD treatment. Despite these changes, a substantial association between specific electrographic findings and clinical outcomes was not established.

Abstract
INTRODUCTION Patients with severe epilepsy are at increased risk of cardiovascular disease and arrhythmias. Although antiseizure medications (ASMs) may have indirect protective effects against cardiovascular events by reducing seizure frequency and hence sudden death in epilepsy, some of them exert cardiotoxic effects. AREAS COVERED Patients with epilepsy, mainly those with severe forms, are at higher risk of cardiac disease because their heart can have structural alterations and electrical instability as a consequence of repeated seizures. Some ASMs have direct protective effects through anti-inflammatory, antioxidant, hypotensive, and lipid-reducing properties. Antiseizure medications can also have toxic cardiac effects including both long-term consequences, such as the increased risk of atherogenesis and subsequent cardiovascular disease due to the influence on lipid profile and pro-inflammatory milieu, and immediate effects as the increased risk of potentially fatal arrhythmias due to the influence on ion channels. Sodium channel blocking ASMs may also affect cardiac sodium channels and this effect is particularly observed in subjects with genetic mutations in cardiac ion channels. Fenfluramine cause valvulopathies in obese subjects and this effect need to be evaluated in epilepsy patients. EXPERT OPINION For the selection of treatment, cardiotoxic effects of ASMs should be considered; cardiac monitoring of treatment is advisable.

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.

Kim HK, Lee H, Bae EK, Kim DW. Cardiac effects of rapid intravenous loading of lacosamide in patients with epilepsy. Epilepsy Res 2021; 176:106710. [PMID: 34265537 DOI: 10.1016/j.eplepsyres.2021.106710] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 06/19/2021] [Accepted: 07/05/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Lacosamide (LCM) is a new antiseizure medication, and intravenous (IV) loading of LCM is recently used against status epilepticus. IV loading of LCM is usually well-tolerated; however, there are concerns about LCM-induced serious adverse cardiac events. This study was aimed at investigating whether rapid IV loading of LCM is associated with adverse cardiac or hemodynamic events in cases of epilepsy emergencies in real-world settings. METHODS We reviewed medical records of consecutive adult epilepsy patients who received a single loading dose (400 mg) of IV LCM between January 2019 and December 2020 and included patients who exhibited status epilepticus or acute repetitive seizures. Electrocardiography findings, blood pressure, and heart rate before and after the IV infusion of LCM were collected. RESULTS Of the 85 patients included, 32.9 % (28/85 patients) had experienced at least one cardiac adverse event. The most common adverse events were new-onset first-degree atrioventricular block (19 patients) and hypotension (seven patients). Atrial fibrillation and bradycardia developed in two patients and atrial flutter in one. There were significant increases in the mean PR interval (from 169.3 msec to 184.5 msec, P < 0.01) and decreases in the mean heart rate (from 91.7 to 86.9, P = 0.01) after IV loading of LCM. Older age was significantly associated with a higher magnitude of the PR interval difference between before and after IV loading of LCM. CONCLUSIONS In cases of epilepsy emergencies, adverse cardiac events commonly developed after IV loading of LCM, although most adverse events were mild in severity or not clinically significant. Elderly patients or patients with underlying cardiac diseases were prone to exhibiting a more prolonged PR interval after IV loading of LCM. Thus, the loading dose of IV LCM should be infused under careful ECG monitoring in these patients.

Effects of antiepileptic drugs on electroencephalography (EEG): Insights and applicability. Epilepsy Behav 2020; 110:107161. [PMID: 32512368 DOI: 10.1016/j.yebeh.2020.107161] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2020] [Revised: 05/02/2020] [Accepted: 05/04/2020] [Indexed: 11/20/2022]
Abstract
OBJECTIVE The objective of the study was to assess the effects of antiepileptic drugs (AEDs) on posterior alpha rhythm and determine whether they produce pathological slow waves in patients with epilepsy. METHODS Outpatient electroencephalographs (EEGs) in alert patients were selected. The three compared groups include 1) patients with an interested AED (monotherapy or combined with other AEDs); 2) patients with AEDs other than the interested AED; and 3) patients who did not take AEDs. Outcomes were frequency of posterior alpha rhythm and presence of generalized continuous (CSWs) and generalized intermittent slow waves (ISWs). Analysis of variance was used to assess which AED was associated with slower posterior alpha rhythm. Chi-square and logistic regression were employed to assess association and odds ratio (OR) with 95% confidence interval (CI) between pathological generalized slow waves and each AED. RESULTS Among 1050 EEG tracings, 638 EEGs met our criteria. Electroencephalographs requested because of cognitive decline and psychiatric symptoms were excluded, leaving 616 EEGs for analysis. Four hundred thirty-seven patients received at least one AED, whereas the remaining 179 patients did not take AED. Conventional AEDs [carbamazepine (CBZ), p = 0.024; phenobarbital (PB), p = 0.013; phenytoin (PHT), p = 0.001] except valproic acid (VPA) were associated with slower alpha frequency. Carbamazepine [adjusted OR: 5.74 (95% CI: 2.07, 15.94)] and PB [adjusted OR: 2.58 (95% CI: 1.15, 5.78)] were significantly associated with generalized ISWs. None were associated with generalized CSWs. CONCLUSIONS Phenytoin, CBZ, and PB are associated with slower posterior alpha frequency. The latter 2 AEDs also produced pathological generalized ISWs. Valproic acid, benzodiazepines, and new-generation AEDs are not associated with either outcome. The presence of generalized ISWs in patients taking CBZ or PB should be cautiously interpreted since there can be drug effects. Association with cognitive side effects of these slow waves should be further studied.

Abstract
People with epilepsy (PWE) are neither more likely to be infected by the coronavirus nor are they more likely to have severe COVID-19 manifestations because they suffer from epilepsy. However, management of COVID-19 in PWE may be more complicated than that in other individuals. Drug-drug interactions could pose significant challenges and cardiac, hepatic, or renal problems, which may happen in patients with severe COVID-19, may require adjustment to antiepileptic drugs (AEDs). In this review, we first summarize the potential drug-drug interactions between AEDs and drugs currently used in the management of COVID-19. We then summarize other challenging issues that may happen in PWE, who have COVID-19 and are receiving treatment.
