BACKGROUND AND PURPOSE: There is sparsity of quality evidence for the use of drugs after first-line benzodiazepines in convulsive status epilepticus in children. The aim of the study was to compare the clinical efficacy and safety of intravenous levetiracetam versus intravenous phenytoin as second-line drugs in the management of generalized convulsive status epilepticus in children. METHODS: This open-label randomized controlled trial was conducted in the Emergency Department of The Children's Hospital and The Institute of Child Health, Multan, Pakistan over a period of 4 years and 6 months from January 2014 to June 2018...

PURPOSE OF REVIEW: Status epilepticus is a neurological emergency associated with high morbidity and mortality. There is a lack of robust data to guide the management of this neurological emergency beyond the initial treatment. This review examines recent literature on treatment considerations including the choice of continuous anesthetics or adjunctive anticonvulsant, the cause of the status epilepticus, and use of nonpharmacologic therapies. RECENT FINDINGS: Status epilepticus remains undertreated and mortality persists to be unchanged over the past 30 years...

BACKGROUND: Phenytoin is the current standard of care for second-line treatment of paediatric convulsive status epilepticus after failure of first-line benzodiazepines, but is only effective in 60% of cases and is associated with considerable adverse effects. A newer anticonvulsant, levetiracetam, can be given more quickly, is potentially more efficacious, and has a more tolerable adverse effect profile. We aimed to determine whether phenytoin or levetiracetam is the superior second-line treatment for paediatric convulsive status epilepticus...

BACKGROUND: Phenytoin is the recommended second-line intravenous anticonvulsant for treatment of paediatric convulsive status epilepticus in the UK; however, some evidence suggests that levetiracetam could be an effective and safer alternative. This trial compared the efficacy and safety of phenytoin and levetiracetam for second-line management of paediatric convulsive status epilepticus. METHODS: This open-label, randomised clinical trial was undertaken at 30 UK emergency departments at secondary and tertiary care centres...

Intravenous levetiracetam has been approved for use as an antiepileptic drug, as well as in cases of status epilepticus. There are few reports that detail the clinical data and outcomes associated with this antiepileptic drug, particularly in patients with renal impairment. This was a retrospective analytical study conducted at Khon Kaen University's Srinagarind Hospital in Thailand. The study period was between January 1, 2010 and December 31, 2014. The inclusion criteria were that patents were over 15 years old, had renal impairment, and had received intravenous levetiracetam treatment...

INTRODUCTION: Intravenous levetiracetam (LEV) is broadly used in the treatment of status epilepticus (SE). A loading dose is usually infused, aiming to reach quickly the range of plasma concentrations considered as therapeutic (12-46 mg/l). The aim of the study was to evaluate the response to LEV in SE, correlated exposure assessed by plasma concentration monitoring, as well as calculated exposure parameters. MATERIALS & METHODS: We retrospectively analyzed a SE registry, including patients since 2015 with at least one available LEV plasma level measured less than 36 h after loading...

Over last fifty years, intravenous (iv) phenytoin (PHT) loading dose has been the treatment of choice for patients with benzodiazepine-resistant convulsive status epilepticus and several guidelines recommended this treatment regimen with simultaneous iv diazepam. Clinical studies have never shown a better efficacy of PHT over other antiepileptic drugs. In addition, iv PHT loading dose is a complex and time-consuming procedure which may expose patients to several risks, such as local cutaneous reactions (purple glove syndrome), severe hypotension and cardiac arrhythmias up to ventricular fibrillation and death, and increased risk of severe allergic reactions...

Status epilepticus (SE) is one of the most frequent neurological emergencies. Despite this, understanding of its pathophysiology and evidence regarding its management is limited. Rapid, effective, and well-tolerated treatment to achieve seizure cessation is advocated to prevent brain damage or potentially lethal outcomes. The last two decades have witnessed an exponential increase in the number of available antiepileptic drugs (AEDs). These compounds, especially lacosamide and levetiracetam, in view of their intravenous formulation, have been increasingly prescribed in SE...

Patients with prolonged seizures that do not respond to intravenous benzodiazepines and a second-line anticonvulsant suffer from refractory status epilepticus and those with seizures that do not respond to continuous intravenous anesthetic anticonvulsants suffer from super-refractory status epilepticus. Both conditions are associated with significant morbidity and mortality. A strict pharmacological treatment regimen is urgently required, but the level of evidence for the available drugs is very low. Refractory complex focal status epilepticus generally does not require anesthetics, but all intravenous non-anesthetizing anticonvulsants may be used...

Levetiracetam is a broad-spectrum antiepileptic drug (AED) with a unique mechanism of action. Older AEDs can cause serious short- and long-term adverse drug reactions and complications, rendering them undesirable to use in pediatric patients. Characteristics that make levetiracetam a near-ideal AED include its broad spectrum of activity, good tolerability profile, and minimal drug-drug interactions. Clinical pharmacokinetic monitoring (CPM) is often recommended in pediatric patients for certain AEDs due to large interindividual pharmacokinetic differences and unpredictable drug disposition...

Convulsive status epilepticus (CSE) is a medical emergency associated with high mortality and morbidity. The most recent definition of CSE is a convulsive seizure lasting more than 5min or consecutive seizures without recovery of consciousness. In adults, for the treatment of the early stages of CSE, diazepam, lorazepam or midazolam are the most common treatments, although the choice of agent seems less important than rapid treatment. Midazolam, when administered intramuscularly (best evidence), buccally, or nasally, is effective and safe in the pre-hospital setting...

BACKGROUND: Seizure following traumatic brain injury (TBI) constitutes a common complication that requires effective prevention to improve the outcome of TBI. Phenytoin has been the only recommended antiepileptic drug (AED) for seizure prophylaxis; however, several shortcomings have affected its use. Intravenous levetiracetam has been available since 2006 and has been increasingly accepted as a seizure prophylaxis for brain injury, mainly due to its favorable pharmacokinetic features and minimal adverse events profile...

BACKGROUND: Generalised convulsive status epilepticus (GCSE) should be treated quickly. Benzodiazepines are the only drug treatment available so far that is effective before admission to hospital. We assessed whether addition of the antiepileptic drug levetiracetam to the benzodiazepine clonazepam would improve prehospital treatment of GCSE. METHODS: We did a prehospital, randomised, double-blind, phase 3, placebo-controlled, superiority trial to determine the efficacy of adding intravenous levetiracetam (2...

Status epilepticus (SE) represents the most severe form of epilepsy. It is one of the most common neurologic emergencies, with an incidence of up to 61 per 100,000 per year and an estimated mortality of 20 %. Clinically, tonic-clonic convulsive SE is divided into four subsequent stages: early, established, refractory, and super-refractory. Pharmacotherapy of status epilepticus, especially of its later stages, represents an "evidence-free zone," due to a lack of high-quality, controlled trials to inform clinical decisions...

Intravenous antiepileptic drugs are required in patients needing urgent treatment or unable to take oral medication. The safety of intravenous levetiracetam has been established in prospective studies of adult epilepsy and healthy participants. The authors performed a prospective, single-center study to evaluate the safety of a rapid loading dose of intravenous levetiracetam. Patients were divided into 3 equal dosing groups (N = 15 each): 20, 40, and 60 mg/kg (corresponding to maximum doses of 1, 2, and 3 g)...
