This is an open labeled non-comparative, multicentric observational post marketing surveillance study to comparing the safety and efficacy of zonisamide as adjunctive therapy or monotherapy in patients with partial, generalized or combined seizures, in a initiating dose of 100mg/day titrated to a maximum of 600mg per day based on the seizure control and tolerability over a 24 weeks treatment period. This study will include a total of 900 patients with partial, generalized or combined seizures across 30 centres in the country. The patients will be enrolled based on the inclusion and exclusion criteria and will be evaluated for safety and efficacy at every 4 weekly interval for 24 weeks. There will be total 7 study visits and the patients will be evaluated for clinically reportable adverse events, safety on Patients Global Assessment of Tolerability to Therapy (PGATT) on a 4-point scale and for efficacy by evaluation of reduction in seizure frequency as the primary objective of the study. For secondary objectives the patients data will be evaluated to determine the responder rates (> or = to 50% reduction in seizure frequency from baseline) and seizure freedom over the 24 weeks study period.
The purpose of this study is to evaluate the safety and efficacy of zonisamide in the treatment of adult patients with partial, generalized or combined seizures.
