zonisamide and Convulsive Generalized Seizure Disorder

zonisamide has been researched along with Convulsive Generalized Seizure Disorder in 22 studies

Zonisamide: A benzisoxazole and sulfonamide derivative that acts as a CALCIUM CHANNEL blocker. It is used primarily as an adjunctive antiepileptic agent for the treatment of PARTIAL SEIZURES, with or without secondary generalization.
zonisamide : A 1,2-benzoxazole compound having a sulfamoylmethyl substituent at the 3-position.
