Levetiracetam is a new anti-epileptic drug that is currently not licensed for use in children. Studies in adults suggest that it may be a useful adjunctive treatment both in partial onset and generalised epilepsy. A retrospective case notes review of 26 children age 10 years and under with refractory epilepsy was undertaken to evaluate the efficacy and safety of the drug. The drug appeared to b...

The combination of transcranial magnetic stimulation and electroencephalography (TMS-EEG) has uncovered underlying mechanisms of two anti-epileptic medications: levetiracetam and lamotrigine. Despite their different mechanism of action, both drugs modulated TMS-evoked EEG potentials (TEPs) in a similar way. Since both medications increase resting motor threshold (RMT), the current aim was to ex...

To the Editor, unmeasured confounding further undermines the validity of comparison between these trials. 6. Some of the studies in the meta-analysis included doses that were found to be non-therapeutic in the pivotal studies and have not been approved for clinical use (brivaracetam 5, 20 and 25 mg/day; levetiracetam 500 mg/day). As such, a brivaracetam dose of 5 mg/day should not be compared t...

RP-HPLC ultraviolet detection simultaneous quantification of piracetam and levetiracetam has been developed and validated. The chromatography was obtained on a Nucleosil C18 column of 25 cm×0.46 cm, 10 μm, dimension. The mobile phase was a (70:30 v/v) mixture of 0.1 g/L of triethylamine and acetonitrile. Smooth flow of mobile phase at 1 mL/min was set and 205 nm wavelength was selected. Results...

INTRODUCTION Prediction of brivaracetam effects in children was obtained by scaling an existing adult pharmacokinetic/pharmacodynamic (PK/PD) model for brivaracetam to children, using an existing population PK model for brivaracetam in children. The scaling was supported by estimating the change from adults to children in the concentration-effect relationship parameters for levetiracetam, a com...

OBJECTIVE To investigate the clinical efficacy and safety of Levetiracetam (LEV) add-on therapy for child refractory epilepsy. PATIENTS AND METHODS Levetiracetam add-on therapy was tested on 65 children who suffered refractory epilepsy, and clinical seizures. Electroencephalogram (EGG) changes and adverse reactions were observed in these children respectively in three, six and twelve months a...

With the advent of new antiepileptic drugs comes the potential for significant advances in the emergent management of status epilepticus. Traditional antiepileptic drugs possess side effect profiles that may limit their clinical utility or lead to increased patient morbidity or mortality. The relatively recent development of levetiracetam shows promise for effective control of acute status epil...

The aim of this audit was to ascertain outcomes for people who had taken or who were still taking three "new generation" broad-spectrum antiepileptic drugs (AEDs), namely lamotrigine, levetiracetam and topiramate. Thirteen percent of people became seizure free and approximately, one-third had a reduction of greater than 50% in their seizures. Two-thirds of people were still taking their audit A...

PURPOSE Systematic evaluation of published evidence-base of the efficacy of five antiepileptic drugs - lacosamide, levetiracetam, valproate, phenytoin and phenobarbital - in convulsive benzodiazepine-resistant status epilepticus. METHODS Data sources included electronic databases, personal communication, and back tracing of references in pertinent studies. These were prospective and retrospec...
