The effects of levetiracetam on urinary 15f-2t-isoprostane levels in epileptic patients

AbstractPurposeWe aimed to investigate the effects of levetiracetam on oxidative stress which is one of the new antiepileptic drugs in epileptic patients.MethodsThe study consisted of 21 patients with cryptogenic partial epilepsy. We determined the urinary 15F-2t-isoprostane levels of the 30 patients which is a marker of oxidative stress. Morning urine samples were collected from the patients before beginning LEV and after 3 months treatment. Of these patients 9 were excluded from the study that had seizure history in the last 1 month. Urinary levels of 15-F2t-isoprostane determined by ELISA initially and after 3 months treatment for each patient.ResultsMean age of the 21 patients was 29.6, of these 11 were females and 10 males. Mean urinary 15F-2t-isoprostane level of the patients was 876±447ng/mg Cr before the treatment of LEV. After 3 months treatment the mean 15F-2t-isoprostane level of the patients was 1560±630. The patients had significantly higher levels of urinary 15F-2t-isoprostane when compared with initial levels (p=0.025).ConclusionOur results showed the increase of urinary 15F-2t-isoprostane levels in epileptic patients whom were treated with LEV which may indicate that LEV induces the oxidative stress in epileptic patients
