Zonisamide is an antiseizure drug chemically classified as a sulfonamide and unrelated to other antiseizure agents. The precise mechanism by which zonisamide exerts its antiseizure effect is unknown, although it is believed that the drug blocks sodium channels which leads to the suppression of neuronal hypersynchronization (i.e. convulsions). Likewise zonisamide has also been found not to potentiate syanptic activity by GABA (gamma amino butyric acid).

Variable, yet relatively rapid rate of absorption with a time to peak concentration of 2.8-3.9 hours. Food has no effect on the bioavailability of zonisamide.

Symptoms of overdose include diminished breathing, loss of consciousness, low blood pressure, and slow heartbeat.
