Clinical experience with brivaracetam in a series of 46 children

Abstract

Objectives: The primary objective of the study was to analyze the efficacy of brivaracetam (BRV) in pediatric patients 12 months after starting treatment. The secondary objective was to establish safety 3, 6, and 12 months after starting treatment.

Materials and method: This was an observational and retrospective study. Data were collected from the electronic medical record. Inclusion criteria were as follows: patients under 18 years of age, diagnosis of focal or generalized epilepsy, treatment as an added therapy, initiation of treatment with BRV between June and September 2017, and at least one unprovoked seizure in the year prior to the start of treatment.

Results: Forty-six patients were included. The response rate was 65%, including 30% seizure-free patients. The rate of adverse effects was 43.5%, resulting in withdrawal in 16 patients (34.7%). The most common adverse effects were drowsiness (17.3%) and irritability (17.3%).

Conclusions: Brivaracetam is effective in very diverse childhood epilepsies, including some that present with primarily generalized seizures. Given the characteristics of the population studied, we have not been able to confirm a better tolerability of BRV compared with levetiracetam (LEV).
