Anti-ictogenic and antiepileptogenic properties of brivaracetam in mature and immature rats (original) (raw)

Epilepsia, 2015

Abstract

Brivaracetam (BRV) is a new antiepileptic drug candidate rationally designed for high affinity and selectivity for the synaptic vesicle protein 2A. This study explored anti-ictogenic and antiepileptogenic effects of BRV in rats at different stages of development. Using a rapid kindling model in P14, P21, P28, and P60 rats, we studied two doses of BRV: 10 and 100 mg/kg injected intraperitoneally 30 min before afterdischarge assessment. We also assessed blood and brain concentrations of BRV 30 min after the injection. BRV 100 mg/kg significantly increased the afterdischarge threshold (ADT) at all ages, whereas BRV at 10 mg/kg increased ADT in P60, P28, and P21 rats. BRV also shortens the afterdischarge duration (ADD), achieving statistical significance with 10 and 100 mg/kg at P60 and with 100 mg/kg at P21. At P60, BRV increases the number of stimulations required to achieve a stage 4-5 seizure in a dose-dependent manner. At P28 and P21, BRV increased the number of stimulations requir...
