Non-Competitive AMPA Receptor Antagonist Perampanel Inhibits Ischemia-Induced Neurodegeneration and Behavioral Deficits in Focal Cortical Pial Vessel Disruption Stroke Model.

ABSTRACT: Glutamate receptors represent a potential target for neuroprotection in neurodegenerative neurological conditions. Perampanel, a non-competitive α-amino-3-hydroxy-5-methyl-4-isoxazole propionate receptor (AMPAR) antagonist, is clinically approved for the management of epilepsy. Perampanel's neuroprotective effects have been reported in global and focal cerebral ischemia models, but the cellular mechanisms remain incompletely understood. Therefore, we studied the potential neuroprotective effects of perampanel in rats using the pial vessel disruption (PVD) stroke model, an established focal cortical non-reperfusion ischemic stroke model. Perampanel was given once intraperitoneally (3 mg/kg body weight) 1 h after PVD surgery and repeated on days 2-3 post-surgery. On the fourth day post PVD,
