Zonisamide is a sulfonamide that exhibits antiepileptic/anticonvulsant and neuroprotective activity and is clinically used to prevent seizures and epilepsy. Zonisamide inhibits carbonic anhydrase, voltage-gated Na+ channels, and T-type Ca2+ channels, and modulates release of GABA and glutamate. In animal models of Parkinson’s disease, zonisamide delays neurodegeneration.
