Abstract
The effects of the putative antiepileptic drug GIZh-298 and the reference standard topiramate on the concentrations of monoamines and their metabolites in the frontal cortex, hypothalamus, nucleus accumbens, striatum, and hippocampus of Wistar rats was investigated using HPLC. It was shown that topiramate at a dose of 100 mg/kg induces an increase in dopamine concentration and a decrease in its metabolism rate in the frontal cortex, a decrease in the level of its metabolites in the dorsal striatum, and an increase in concentrations of dopamine and its metabolites in the hypothalamus 30 minutes after injection. GIZh-298 at a dose of 60 mg/kg caused an increase in the serotonin and dopamine concentration in the frontal cortex and a decrease in the dopamine metabolism rate in the dorsal striatum 30 minutes after injection, which may be considered as one of the components of the antiepileptic effect of this drug.
