Neuroprotective effect of topiramate on hypoxic ischemic brain injury in neonatal rats.

Perinatal hypoxia-ischemia is one of the most common risk factors for neonatal mortality and permanent neurodevelopmental disability. Topiramate [2,3:4,5-bis-o-(1-methylethylidene) beta-D-fructo-pyranose sulfamate; TPM] is widely used as an antiepileptic agent with multiple targets. In the present study, we found that treatment with TPM reduced the neuronal damage induced by oxygen-glucose deprivation in vitro with strong inhibition of the alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA) receptor.
