Safinamide (intraperitoneal injection; 90 mg/kg; once daily; 14 days) treatment prior to MCAO significantly ameliorates MCAO-caused cerebral infarction volume, neurological deficit, disruption of the brain-blood barrier (BBB), and impairs expression of tight junction protein occludin and ZO-1 in mice.
Safinamide (intraperitoneal injection; 5 mg/kg, 15 mg/kg and 30 mg/kg) dose dependently inhibits the veratridine-induced GABA release and Glu release in vivo. At the dose 30 mg/kg, Safinamide prevents the effect of veratridine both on Glu (treatment F1,8=1.31; time×treatment interaction F8,64=2.4) and GABA (treatment F1,8=4.04; time F8,64=3.76, time×treatment interaction F8,64 = 2.83) release.
Safinamide causes a slight, albeit not significant, reduction of veratridine-stimulated Glu release at 0.5 mg/kg and full inhibition at 5 and 15 mg/kg in rat.
