Biological Activity for Zonisamide

Zonisamide is a antiepileptic that possesses a broad spectrum anticonvulsant and mechanistic profile. Blocks voltage-sensitive Na⁺ and T-type Ca²⁺ channels, stimulates BK_Ca channels, modulates GABA, glutamate and monoamine neurotransmission, inhibits lipid peroxidation and scavenges hydroxyl and nitric oxide free radicals. Displays neuroprotective and antiParkinsonian activity.
