Background and objective. Many studies have shown associations between HLAB*15:02, HLA-A*31:01 and carbamazepine (CBZ)-induced delayed cutaneous hypersensitivity reactions. The aim of this study is to evaluate a possible association between delayed cutaneous reactions to antiepileptic drugs (AEDs) and certain HLA-A and HLA-B alleles in the Turkish population. Methods. The study consisted of 3 groups: Group I (reactive group) included the patients who had documented delayed cutaneous reactions to any antiepileptic drug...

Levetiracetam is one of the newer second-generation antiepileptic drugs with multiple mechanisms of action. Cutaneous side effects due to levetiracetam are rarely reported in the literature. In this article, we describe a patient with skin hyperpigmentation due to the treatment with levetiracetam with complete resolution after discontinuation of the medication. In addition, we review the topic and hypothesize the mechanism behind this rare complication. To the best of our knowledge, this is the first report of skin hyperpigmentation as a side effect of levetiracetam in the literature...

OBJECTIVE: Current antiepileptic drugs (AEDs) have several shortcomings. For example, they fail to control seizures in 30% of patients. Hence, there is a need to identify new AEDs. Drug repurposing is the discovery of new indications for approved drugs. This drug "recycling" offers the potential of significant savings in the time and cost of drug development. Many drugs licensed for other indications exhibit antiepileptic efficacy in animal models. Our aim was to create a database of "prescribable" drugs, approved for other conditions, with published evidence of efficacy in animal models of epilepsy, and to collate data that would assist in choosing the most promising candidates for drug repurposing...

Background: Health professionals may advise women to either stop breastfeeding or drug treatment due to restrictive advice in drug monographs. Regional medicines information and pharmacovigilance centres in Norway (RELIS) provide free and industry-independent answers to questions about drugs and breastfeeding documented in a full-text, searchable database (RELIS database). We used the RELIS database to describe which health care practitioners sought information about medication safety in lactation, most common drugs involved, advice provided and which resources were used to provide the advice...

OBJECTIVES: One-third of epileptic patients are resistant to antiepileptic drugs. Few clinical studies with small sample size indicate that polyunsaturated fatty acids could control drug-resistant epilepsy. We examined the efficacy of acute and chronic administration of docosahexaenoic acid (DHA) in two animal models of drug-resistant epilepsies, i.e. 6-Hz psychomotor seizures in mice and lamotrigine (LTG)-resistant kindled rats. METHODS: Mice received a single injection of DHA (300 µM, i...

Modulation of the immune system has recently been shown to be involved in the pharmacological effects of old antiepileptic drugs and in the pathogenesis of epilepsy. Therefore, the most recent guidelines for immunotoxicological evaluation of drugs were consulted to investigate the immunomodulatory effects of lamotrigine, a newer antiepileptic drug, in BALB/c mice. These included the in vivo effects of lamotrigine on delayed-type hypersensitivity (DTH) response to sheep red blood cell (SRBC) antigens, hemagglutination titer assays and hematological changes...

This study aimed to investigate the incidence of aggressiveness in patients with severe drug-refractory focal epilepsy (DRE) who started perampanel (PER) as add-on treatment, and to identify possible predisposing factors. Data on 49 consecutive patients with severe DRE who initiated PER were retrospectively collected. Twelve of the 49 patients experienced aggressiveness as adverse event related to PER treatment, one third of them on low (2-4 mg/day) PER dosages. PER was discontinued in 10/12 patients because of aggressive behaviors...

BACKGROUND: Nipecotic acid is considered to be one of the most potent inhibitors of neuronal and glial γ- aminobutyric acid (GABA) uptake in vitro. However nipecotic acid does not readily cross the blood-brain barrier (BBB) following peripheral administration, owing to its hydrophilic nature. OBJECTIVE: A series of substituted acetonaphthones tethered nipecotic acid derivatives were designed and synthesized with an aim to improve the lipophilicity and the blood-brain barrier (BBB) permeation...

Cardiac arrhythmia may occur in the course of epilepsy. Simultaneous therapy of the two diseases might be complicated by drug interactions since antiarrhythmic and antiepileptic agents share some molecular targets. The aim of this study was to evaluate the influence of amiodarone, an antiarrhythmic drug working as a multi-channel blocker, on the protective activity of four classical antiepileptic drugs in the maximal electroshock test in mice. Amiodarone at doses up to 75 mg/kg did not affect the electroconvulsive threshold in mice...

PURPOSE OF REVIEW: As the number of patients diagnosed with epilepsy continues to rise and the pharmacological and device-based treatment options for epilepsy increase, determining when to stop antiepileptic drug (AED) treatment continues to be an important issue for patient management and counseling. RECENT FINDINGS: This review focuses on outcomes following AED withdrawal in seizure-free adults with epilepsy. Practical considerations are also discussed because, despite the importance of this topic, relatively little progress has been made in the past year regarding the identification of patients whose risk for recurrent seizures after AED withdrawal is no higher than that of the general population...

Background Reversible splenial lesion syndrome is a distinct entity radiologically characterized by a reversible lesion in the splenium of the corpus callosum. According to previous reports, this condition may be associated with antiepileptic drug use or withdrawal. We herein report a case of reversible splenial lesion syndrome associated with oxcarbazepine withdrawal. Case Report A 39-year-old man presented with an 8-year history of epileptic seizures. During the previous 3 years, he had taken oxcarbazepine irregularly...

S(+)-ketamine, the pure dextrorotatory enantiomer of ketamine has been available for clinical use in analgesia and anesthesia for more than 25 years. The main effects are mediated by non-competitive inhibition of the N-methyl-D-aspartate (NMDA) receptor but S(+)-ketamine also interacts with opioid receptors, monoamine receptors, adenosine receptors and other purinergic receptors. Effects on α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors, metabotropic glutamate receptors (mGluR) and L‑type calcium chanels have also been described...

Bumetanide is a loop diuretic that is proposed to possess a beneficial effect on disorders of the central nervous system, including neonatal seizures. Therefore, prediction of unbound bumetanide concentrations in brain is relevant from a pharmacological prospective. A physiologically-based pharmacokinetic (PBPK) model was developed for the prediction of bumetanide disposition in plasma and brain in adult and pediatric populations. A compound file was built for bumetanide integrating physicochemical data and in vitro data...

Background: Epilepsy is a common complication in patients with severe motor and intellectual disabilities (SMID). There are no reports as yet of the effects of these medications in vivo other than their epileptic efficacy. The purpose of this study was to clarify the effects of the newer antiepileptic drugs (AEDs) on the blood biochemical parameters and oxidative stress in SMID with epilepsy by comparing the therapeutic effects between a group of patients receiving lamotrigine (LTG) and levetiracetam (LEV) in addition to the conventional AEDs (newer AED group) and a group receiving conventional AEDs alone (old AED group)...

Yating Wu, Aihua Liu
Epilepsy is a common chronic brain disorder with multiple causes, and now autoimmune factors are believed to be an independent cause for epilepsy. Accumulating data support an autoimmune basis in patients with antiepileptic drug-resistant seizures. Moreover, systemic autoimmune diseases and epilepsy co-occur frequently. Neural specific autoantibodies can also mediate the process of seizures through different pathways. The diagnosis of autoimmune epilepsy is based on frequency of antiepileptic drug-resistant seizures, the presence of neural specific autoantibodies, inflammatory changes in serum or spinal fluid or on magneticresonanceimaging, the change in electroencephalogram, a personal or family history of autoimmunity...

Histone deacetylation, together with altered acetylation of NF-κB/RelA, encompassing the K310 residue acetylation, occur during brain ischemia. By restoring the normal acetylation condition, we previously reported that sub-threshold doses of resveratrol and entinostat (MS-275), respectively, an activator of the AMP-activated kinase (AMPK)-sirtuin 1 pathway and an inhibitor of class I histone deacetylases (HDACs), synergistically elicited neuroprotection in a mouse model of ischemic stroke. To improve the translational power of this approach, we investigated the efficacy of MS-275 replacement with valproate, the antiepileptic drug also reported to be a class I HDAC blocker...
