The Tell on Telehealth.

Objective: Telehealth in epilepsy care is not new. During the COVID-19 public health emergency, telehealth became more readily used to deliver epilepsy care. However, a summarized guidance of use in caring for people with epilepsy utilizing telehealth is needed.

The Adverse Effects of Commonly Prescribed Antiseizure Medications in Adults With Newly Diagnosed Focal Epilepsy.

Background And Objectives: Systematic screening can help identify antiseizure medication (ASM)-associated adverse events (AEs) that may preclude patients from reaching effective doses or completing adequate trial periods. The Adverse Event Profile (AEP) is a self-completed instrument to identify the frequency of common AEs associated with ASM use. This study aimed to compare the AE profile of commonly used ASMs in adults with newly diagnosed focal epilepsy.

Consensus panel recommendations for the optimization of EPIDIOLEX® treatment for seizures associated with Lennox-Gastaut syndrome, Dravet syndrome, and tuberous sclerosis complex.

Following the approval of Epidiolex® (cannabidiol; CBD) for the treatment of seizures associated with Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS), and tuberous sclerosis complex (TSC), healthcare professionals (HCPs) have had substantial experience in treating patients with Epidiolex. However, confusion still remains among HCPs, caregivers, and patients regarding dosing, drug interactions, safety monitoring, and differentiation between Epidiolex and nonapproved CBD products. To establish consensus recommendations for Epidiolex treatment optimization in LGS, DS, and TSC, a panel of seven HCPs with expertise in epilepsy was convened.

Intranasal Delivery of Medications for the Treatment of Neurologic Conditions: A Pharmacology Update.

INTRODUCTION: Nurses have a central role in educating patients and families about treatment options and how to integrate them into action plans for neurologic conditions. In recent years, a growing number of intranasal formulations have become available as rescue therapy for neurologic conditions or symptoms including migraine, opioid overdose, and seizures. Rescue therapies do not replace maintenance medications or emergency care but are designed to enable rapid treatment of urgent or disabling conditions in community settings.

Product labeling accuracy and contamination analysis of commercially available cannabidiol product samples.

Commercially available cannabidiol (CBD) products are increasingly being used for medicinal purposes, including for the treatment of various neurological conditions, but there are growing concerns around adherence to quality control measures that protect consumers. This study was conducted to assess the purity and label accuracy of commercially available CBD products. Commercially available CBD products were chosen from the open stream of commerce in the United States based on formulations as a tincture, gummy, vape, or topical product.

Lacosamide extended-release capsules are bioequivalent to lacosamide immediate-release tablets: Pharmacokinetic observations and simulations.

Objectives: Assess the bioequivalence of lacosamide extended-release (XR) capsules and immediate-release (IR) tablets and answer real-world clinical questions regarding the use of lacosamide XR.

Methods: An open-label, randomized, two-treatment, two-sequence, oral comparative bioavailability study was conducted to assess the bioequivalence of two lacosamide formulations. Participants were randomized 1:1 to receive lacosamide XR capsules (400 mg once-daily) or IR tablets (200 mg twice-daily) in 1 of 2 sequences over 7-day periods.

Zonisamide: A Comprehensive, Updated Review for the Clinician.

Purpose Of Review: Zonisamide (ZNS) was first approved in the United States in 2000 for the adjunctive treatment of patients aged 16 years or older with partial (focal) seizures. Although ZNS has been proven to treat multiple seizure types, it has been largely underutilized in US clinical practice.

Recent Findings: Published literature demonstrated that antiseizure medications (ASMs) acting on Na and Ca channels may add beneficial effects in many seizure types by reducing seizure frequency and leading to overall improvements.

Lamotrigine use and potential for adverse cardiac effects: A retrospective evaluation in a Veteran population.

Objective: To identify the impact of lamotrigine (LTG) on cardiac rhythm and conduction abnormalities for Veterans, an especially vulnerable population.

Background: In October 2020 the US Food and Drug Administration (FDA) added a new warning to the label of lamotrigine (Lamictal™) regarding its potential to cause cardiac rhythm and conduction abnormalities [1]. This warning came following in vitro data which suggested Class IB antiarrhythmic effects occurring at clinically achievable concentrations of lamotrigine [2].

Practical Questions About Rescue Medications for Acute Treatment of Seizure Clusters in Children and Adolescents with Epilepsy in the USA: Expanding Treatment Options to Address Unmet Needs.

Epilepsy is a common pediatric neurological condition, affecting approximately 470,000 children in the USA and having a prevalence of 0.9% in the global population of approximately 2.6 billion children.

Patterns of antiseizure medication utilization in the Human Epilepsy Project.

Objective: This study was undertaken to ascertain the natural history and patterns of antiseizure medication (ASM) use in newly diagnosed focal epilepsy patients who were initially started on monotherapy.

Methods: The data were derived from the Human Epilepsy Project. Differences between the durations of the most commonly first prescribed ASM monotherapies were assessed using a Cox proportional hazards model.

Patterns of psychotropic drug use in veterans with epilepsy: Do drug interactions matter?

Rationale: Patients with epilepsy are likely to suffer from psychiatric comorbidities, including depression and anxiety. They often require treatment with multiple psychotropic drugs (PDs). While it is clear that CYP-inducing ASMs (EIASMs) can increase the oral clearance of multiple medications (thus lowering systemic exposure), it is less clear that all PK interactions are clinically meaningful (e.

Real-world, long-term evaluation of the tolerability and therapy retention of Epidiolex® (cannabidiol) in patients with refractory epilepsy.

Objective: Epidiolex® (CBD) is FDA-approved for seizures associated with Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS), and tuberous sclerosis complex (TSC). Phase III studies suggest that certain adverse effects (AEs), possibly linked to pharmacokinetic/pharmacodynamic (PK/PD) interactions may be therapy-limiting. We sought to identify these factors that contribute to treatment success and retention of therapy.

Paxlovid Information From FDA and Guidance for AES Members.

This American Epilepsy Society (AES) official statement provides information and preliminary guidance to Society members related to the U.S. Food & Drug Administration (FDA) December 22, 2021 Emergency Use Authorization for Paxlovid™ for the oral treatment of mild to moderate COVID-19 in adults and children (≥12 years and weighing ≥40 kg).

Rescue Treatments for Seizure Clusters.

Treatment of seizure clusters endeavors to prevent additional seizures and avoid progression to conditions such as prolonged seizures and status epilepticus. Rescue therapies are key components of seizure action plans (SAPs) for individuals with seizure clusters. Three rescue therapies are approved in the United States for the treatment of seizure clusters: diazepam rectal gel, midazolam nasal spray, and diazepam nasal spray.

Opportunities for Community Pharmacists to Counsel Patients With Epilepsy and Seizure Clusters to Overcome Barriers and Foster Appropriate Treatment.

Some patients with epilepsy experience seizure clusters, which may be defined as 2 or more seizures occurring within 24 hours. Left untreated, seizure clusters increase the risk for physical injury and may progress to status epilepticus, irreversible neurologic injury, and death. Rescue therapy is based on benzodiazepine treatment.

Rescue therapies for seizure clusters: Pharmacology and target of treatments.

The primary goal of treatment for seizure clusters is cessation of the cluster to avoid progression to more severe conditions, such as prolonged seizures and status epilepticus. Rescue therapies are key components of treatment plans for patients with seizure clusters. Three rescue therapies are approved in the United States for the treatment of seizure clusters: diazepam rectal gel, midazolam nasal spray, and diazepam nasal spray.

Considerations for determining the efficacy of new antiseizure medications in children age 1 month to younger than 2 years.

Objectives: Drug treatment for children with epilepsy should, ideally, be governed by evidence from adequate and well-controlled clinical studies. However, these studies are difficult to conduct, and so direct evidence supporting the informed use of specific drugs is often lacking. The Research Roundtable for Epilepsy (RRE) met in 2020 to align on an approach to therapy development for focal seizures in children age 1 month <2 years of age.

Impact of Clinical Pharmacists on Access to Care in an Epilepsy Clinic.

Background: Epilepsy affects about 1% of the world population and is one of the most burdensome diseases in terms of disability-adjusted life-years. The demand for neurologists and epileptologists is expected to exceed current supply by 2025. One potential strategy to increase access to epilepsy care is to utilize clinical pharmacist practitioners (CPPs) with a broad scope of practice.

Analysis of cannabidiol (CBD) and THC in nonprescription consumer products: Implications for patients and practitioners.

Purpose: Cannabidiol products remains largely unregulated in the US. Unlike the Rx formulation of CBD [Epidiolex], little information is available regarding labeling accuracy (does the product contain what the label says it does), lot to lot variability, nor long-term product stability. Understanding these properties are fundamental if these products are to be used in patients with epilepsy, where product variability of traditional AEDs has been suspected to result in inadequate seizure control.

Extending the reach of science - Talk in plain language.

There has been increasing interest by the general public to read and share mainstream medical and scientific literature. Consequently, more and more medical journals are adopting strategies to make complex literature more accessible to the lay public. One such strategy is the creation of so called "lay summaries".

Interindividual Variability in the Bioavailability of Gabapentin Enacarbil Extended Release in Healthy Adults: An Analysis of Data From 6 Phase I Studies.

Background: The absorption and bioavailability of oral gabapentin are associated with a high degree of interindividual variability. Gabapentin enacarbil, a prodrug of gabapentin, is well absorbed and provides sustained, dose-proportional exposure to gabapentin. The aim of this analysis was to describe the interindividual variability in the bioavailability of gabapentin after gabapentin enacarbil administration in healthy subjects.

Levetiracetam-associated irritability and potential role of vitamin B6 use in veterans with epilepsy.

Objectives: Levetiracetam, a commonly prescribed antiseizure medication (ASM), may cause irritability, depression, and anger. The mechanisms underlying these behavioral effects and individual risk factors remain unknown. Mitigation strategies are limited, including discontinuation, supplementation with vitamin B6, or switching to an alternative ASM.
