[Use of keppra during the radiotherapy in patients with brain tumors and epileptic seizures after surgical treatment].

Efficacy of keppra was studied in 52 patients, aged 10-55 years, after the surgical treatment of gliomas of the brain hemispheres. The medication was used (in combination with other anticonvulsant drugs and hormones) during the radiotherapy. In 30 (57,8%) of cases epileptic seizures were before the surgery. In 22 (42,2%) of patients they developed during the radiotherapy. Keppra was used in the regiment of "urgent aid" in relation to the appearance of seizures and increase of their frequency during the radiotherapy. Doses of keppra varied from 500 to 2500 mg (30-50 mg/kg/day) in a single dose. Then patients received the drug 2 times daily under the control of clinical and EEG presentations. A clinical effect, including the decrease of seizures frequency by 48,3% (p<0,001), positive changes of quality of seizures (more simple structure, reduced time of seizures), was observed for the first 24 h and in future the state of patients was stable. All patients have completed the course of radiotherapy. The choice of dose was depended on age, body mass and dynamics of clinical and EEG data.
