Zonisamide is used as an active component with an anticonvulsant property. The exact mechanism of action is not completely known. This active component blocks sodium and calcium channels to stabilize neuronal membranes and suppress neuronal hyper-synchronization. It shows an affinity for gamma-aminobutyric acid but does not potentiate the synaptic activity of GABA. This active agent also facilitates both dopaminergic and serotonergic neurotransmission. It is an anticonvulsant used in combination with other antiepileptic medicines for partial-onset seizures.
