For LEV 45-min intravenous administration,bioequivalence versus 1500-mg tablets was within the range for Cmax and AUC 0-t. The most frequently adverse event (AE)was somnolence.A total of eight subjects experienced nine mild AEs in study A, and 19subjects experienced 29mild AEs in study B.Intravenous infusions (15 and 45 min)of 1500-mg LEV were as well tolerated as the oral tablet.Bioequivalence was demonstrated by 45-min infusions.Therefore,direct conversion from oral to intravenous LEV 1500 mg (45-min infusion),or vice versa,was possible.展开更多

Their demographic data, clinical characteristics, etiology, seizures, electroencephalograms, response to treatment and outcome were noted. Literature review of use of LEV in neonates were also performed via Pub Med and EMBASE with keywords- "neonates", "seizures", "epilepsy" and "LEV" up to Sep 2014 and retrieved the publications. The response rate to LEV was compared.RESULTS: Twelve neonates were identified during the study period. All patients received phenobarbitone loading prior to consideration of LEV. Seven(58%) and nine(75%) achieved seizure freedom 24 h and 72 h after LEV was added, both clinically and electrographically. No serious adverse effects were associated with LEV use. From the literature, there are total 144 neonates reported to have used LEV. The overall results suggested that LEV could control up to 90% of neonatal seizures.CONCLUSION: LEV was found to be relatively safe and efficacious in treating neonatal seizures, but might not work well in the most severe hypoxic ischemic encephalopathy.展开更多

Acute kidney injury (AKI) is sometimes present in the form of an acute interstitial nephritis. We present the case of a 75-year-old man with glioblastoma who developed a DRESS two months after starting levetiracetam and a few days after stopping dexamethasone. His skin and kidneys improved after removing levetiracetam and introducing again corticosteroids. DRESS has been reported more frequently with other antiepileptics, rarely with levetiracetam. Clinicians should add this drug to the list of potential causes of AKI.展开更多

Patients in the control group were treated with routine treatment, those in observation group were treated with routine treatment plus adjuvant levetiracetam therapy, and the treatment lasted for 20 weeks. Serum contents of nerve cytokines and apoptosis molecules were compared between two groups before and after treatment.Results:Before treatment, differences in serum levels of nerve injury indexes, nerve protection indexes, monoamine neurotransmitters and apoptosis molecules were not statistically significant between two groups of patients. After treatment, serum contents of nerve injury indexes S-100β, GFAP, NSE and MBP in both groups were significantly lower than those before treatment, contents of nerve protection indexes BDNF and IGF-1 were significantly higher than those before treatment, contents of monoamine neurotransmitters DA, 5-HT and NE were significantly higher than those before treatment, contents of apoptosis molecules Bcl-2, Fas and FasL were significantly lower than those before treatment, and the changes in contents of above indexes in observation group were larger than those in control group.Conclusion:The adjunctive therapy of levetiracetam can reduce the nerve injury in patients with refractory partial epileptic seizure and exert active cerebral protective effect.展开更多

Levetiracetam is considered as one of common antiepileptic drugs used to manage epilepsy with good efficacy and tolerability profile. It is renally excreted and not depending on the cytochrome p450. It has adverse effects reported as somnolence, headaches, dizziness, depression and anxiety. Also, it was reported that levetiracetam can cause Acute kidney injury (AKI), renal profile disturbance, that may be related to its way of excretion and possible nephrotoxicity especially with high loading dose. We are reporting a young female patient with epilepsy presented to hospital with status epileptcus and started on loading dose of levetiracetam 3 grams and then maintenance dose of 1 gram twice daily seizure were controlled but she developed acute kidney injury that improved after discontinue leveriracetam and medical management without renal dialysis and discharged home in stable condition. Physician and health care providers should be aware of such rare adverse reaction and available management options for better patient care and outcome.展开更多
