Demonstration of the effect of brivaracetam on an experimental epilepsy model
Background/aim:
The aim of this study was to investigate the effects of valproic acid (VPA) and a new-generation antiepileptic drug
called brivaracetam (BRV) on the brain damage occurring after status epilepticus (SE) in rats.
Materials and methods:
In our study, an experimental animal model of SE, generated by stereotaxically injecting 0.4-2 μg of kainic
acid into the rat hippocampus, was used. The laboratory animals were divided into 4 groups: the first group was a sham group that
was subjected to anesthesia and SE was not induced; the second group was a SE group, in which SE was induced using kainic acid but
subjects were not treated; the third group was the VPA group, in which SE was induced using kainic acid and subjects were treated with
VPA; and the fourth group was the BRV group, in which SE was induced using kainic acid and subjects were treated with BRV.
Results:
Annexin V and p53 levels were statistically higher in the SE group than in the sham group (P < 0.001). Following the treatment
with VPA and BRV, a substantial decrease was observed in the annexin V and p53 levels compared to those of the SE group (P < 0.001).
There was a statistically significant increase in Bcl-2 levels after VPA and BRV treatment compared to the SE group (P < 0.001).
Conclusion:
Our study showed that VPA and BRV are protective against neuronal damage occurring after SE in rats due to the increase
in Bcl-2.
