[Efficacy and safety of topiramate depending on patient's age and forms of epilepsy]

Seven hundreds and twenty-two epileptic patients receiving topiramate (374 males, 348 females), aged from 3 month to 57 years, were followed with video-EEG control during the period of 2002-2012. Topiramate was effective in 465 (64.4%) patients, and among them the efficacy of monotherapy (72.2%) was higher compared to combined therapy (61.9%). The low efficacy was seen in 198 (27.4%) patients. The aggravation effect was noted in 59 (8.2%) of patients. Drug compliance (for >1 year) was 60.7%. In the group <1 year, the high efficacy was observed in 55.2%, low efficacy - in 34.5%, aggravation - in 10.3%. In the group 1-3 years, these indicators were 54.8%, 31.8% and 13.4%, respectively. In the pediatric population (>3 years), they were 67.3%, 26.2% and 6.5% as well as in the adult population (>18 years) - 82.1%, 16.6% and 1.3%, respectively. Thus, topiramate is a highly effective medication in the therapy of idiopathic generalized epilepsies without absences and in symptomatic/cryptogenic focal forms of epilepsy. The efficacy of topiramate raised with increasing of age while the aggravation risk decreased significantly.
