OBJECTIVES: To report the results of a combined case series analysis of subcutaneous levetiracetam (Keppra) for the management of seizures in palliative care patients. METHODS: A comprehensive literature review on the use of subcutaneous levetiracetam was performed, and these data were combined with a prospective observational audit of its use in terminal care undertaken in a regional palliative care network. RESULTS: 7 papers were identified from the literature review-four case reports and three observational case series-reporting on a total of 53 cases where subcutaneous levetiracetam was administered...

BACKGROUND: Switching patients from a branded antiepileptic drug (AED) to a generic is often challenging. Several studies have shown that considerable proportions of patients report deteriorated seizure control or increased adverse effects, enforcing a switchback to the original drug. Since tolerability and seizure control usually correlate with AED serum concentrations, we examined the fluctuation of levetiracetam (LEV) serum concentrations in patients with epilepsy before and after generic substitution...

Sporadic late-onset Alzheimer's disease (LOAD), the most common form of dementia in the elderly, causes progressive and severe loss of cognitive abilities. With greater numbers of people living to advanced ages, LOAD will increasingly burden both the healthcare system and society. There are currently no available disease-modifying therapies, and the failure of several recent pathology-based strategies has highlighted the urgent need for effective therapeutic targets. With aging as the greatest risk factor for LOAD, targeting mechanisms by which aging contributes to disease could prove an effective strategy to delay progression to clinical dementia by intervention in elderly individuals in an early prodromal stage of disease...

PURPOSE: The therapeutic equivalence of generic and brand antiepileptic drugs, based on studies performed on healthy volunteers, has been questioned. We compare, in a routine clinical setting, brand versus generic levetiracetam (LEV) bioequivalence in patients with epilepsy and also the clinical efficacy and tolerability of the substitution. METHODS: A prospective, open-label, non-randomized, steady-state, multiple-dose, bioequivalence study was conducted in 12 patients with epilepsy (5 females), with a mean age of 38...

A recently identified mechanism for oligomeric Aβ-induced glutamate release from astrocytes involves intracellular Ca elevation, potentially by Ca-dependent vesicular release. Evidence suggests that levetiracetam (LEV; Keppra), an antiepileptic drug, can improve cognitive performance in both humans with mild cognitive impairment and animal models of Alzheimer disease. Because LEV acts by modulating neurotransmitter release from neurons by interaction with synaptic vesicles, we tested the effect of LEV on Aβ-induced astrocytic release of glutamate...

BACKGROUND: Rapidly disintegrating or 'fast-melt' oral formulations have been developed recently to facilitate drug intake among patients. Even though these formulations have helped to improve therapy adherence, some of their limitations include: the dissolution time, their facility to be swallowed, and the dosage strengths that may be accommodated. To overcome these limitations, a novel, porous, quickly disintegrating, and easier-to-swallow fast-melt formulation based on powder-liquid, three-dimensional printing (3DP) technology has been developed...

Surveys among women with epilepsy (WWE) show that they receive their essential pregnancy-related information from many sources, including the internet. Our aim was to assess the types of websites provided by searching Google for the use of four antiepileptic drugs (AEDs) during pregnancy and lactation. The search was performed on 40 computers used by health-care professionals, on 40 computers used by nonhealth-care professionals, and on 5 computers used by WWE in Israel and on 8 computers used by nonhealth-care professionals in the U...

REVIEW
Gail D Anderson, Russell P Saneto
Modified-release or extended-release (XR) formulations are used to decrease the frequency of dosing for drugs with rapid elimination, to improve convenience and adherence. Use of a modified-release formulation can decrease the peak to trough fluctuations in serum concentrations and theoretically improve the therapeutic benefit of the drug, by decreasing adverse events associated with the higher peak concentrations. Once-daily formulations of lamotrigine (Lamictal XR(®)), levetiracetam (Keppra XR(®)), oxcarbazepine (Oxtellar XR(®), Apydan(®) extent) and topiramate (Qudexy XR™, Trokendi XR™) are approved for the treatment of focal and/or generalized onset seizures...

BACKGROUND: Seizures account for significant morbidity and mortality early in the course of traumatic brain injury (TBI). Although there is sufficient literature suggesting short-term benefits of antiepileptic drugs (AEDs) in post-TBI patients, there has been no study to suggest a time frame for continuing AEDs in patients who have undergone a decompressive craniectomy for more severe TBI. We examined trends in a level-II trauma center in southern California that may provide guidelines for AED treatment in craniectomy patients...

Levetiracetam, trade name Keppra, is a new second generation antiepileptic drug that is being increasingly used in brain tumor patients. In patients suffering with brain tumors, seizures are one of the leading neurologic complications being seen in more than 30% of patients. Unlike other antiepileptic drugs, levetiracetam is proposed to bind to a synaptic vesicle protein inhibiting calcium release. Brain tumor patients are frequently on chemotherapy or other drugs that induce cytochrome P450, causing significant drug interactions...

BACKGROUND: A simple LC-MS/MS method was developed and validated for the quantification of levetiracetam (LEV, Keppra®), a broad-spectrum antiepileptic drug (AED) in rat dried blood spots (DBS). LEV was simply extracted with methanol spiked with adenosine (ADE) as IS before LC-MS/MS analysis. The correlation between the DBS and plasma concentrations of LEV was also determined. RESULTS: Linearity was from 0.067-60 µg/ml for LEV in DBS samples. The intra- and inter-day accuracy and precision of the assay met validation acceptance criteria...

Extended release (XR) formulation of levetiracetam (LEV) is approved by the Food and Drug Administration as an add-on to other antiepileptic drugs (AEDs) for adults with partial onset seizures. This is based on class-I evidence demonstrating significant seizure reduction in once daily dosing. Keppra-XR is marketed with the brand name of Keppra XR since 2008 (UCB Pharma). Its original immediate release (IR) formulation has been in the market since 2000. LEV has a unique molecular structure which is chemically unrelated to existing AEDs...

Levetiracetam (brand name: E Keppra®) is a new antiepileptic drug marketed in Japan since 2010 1, 2). Clinical reports of its use in Japan are few. Our experience with levetiracetam in a patient with secondarily generalized seizures yielded interesting findings. The patient was a 62-year-old man receiving 4 antiepileptic drugs and 9 psychotropic drugs for treatment of secondarily generalized seizures (due to a cerebral contusion that occurred 20 years ago) and associated depressive symptoms, mainly anxiety and insomnia...

Pervasive developmental disorder is characterized by various symptoms that often include self-injurious behavior (SIB). Episodes of SIB occur in the context of high emotional arousal, anger, or fear and may be related to epilepsy. We report the case of a 20-year-old man with pervasive developmental disorder presenting with SIB non-responsive to antipsychotic medication. Positron emission tomography showed a right temporoparietal hypometabolic focal lesion suggestive of an epileptic focus. Two weeks after initiation of levetiracetam (Keppra®), SIB disappeared, without recurrence 24 months later...
