According to the International League Against Epilepsy (ILAE) classification of seizure type (1981) and international classification of epilepsies and epileptic syndromes (ILAE, 1989), definite diagnosis of partial seizures (with or without secondary generalized seizures) refractory to current anti epilepsy drug (AED) therapy.
1. Adult male or female, 16 to 70 years old;
2. Classified according to the ILAE classification of seizure type (1981) and international classification of epilepsy and epileptic syndromes (ILAE, 1989) into partial seizures (with or without secondary generalized seizures);
3. Based on the retrospective subject diary, at least 4 partial seizures per month ( 4 weeks ) within 12 weeks prior to entry;
4. No more than 8 secondary generalized tonic, clonic, or tonic-clonic seizures per month within 12 weeks prior to entry;
5. Antiepileptic therapy including at least 1-2 concomitant AEDs and were on a stable dose(s) of the same AEDs for the 3 months prior to enrollment;
6. Had performed electro encephalogram (EEG) within 6 months prior to entry, and computer tomography (CT) or magnetic resonance imaging (MRI) examination to mainly exclude space-occupying disease;
7. Was able to count seizure frequencies;
8. Women with child bearing potential, were not to be pregnant or nursing, and must have agreed to practice during the study a reliable form of contraception (oral contraceptive, condom, intrauterine device or diaphragm).
9. Signed written informed consent and agreed to comply with the protocol.

2. Nonepileptic seizures and pseudoepileptic seizures;

13. History of zonisamide administration;
14. History of acetazolamide administration to treat epilepsy within 2 months prior to entry;
15. Joined the clinical trial of other AEDs within 30 days prior to entry;
16. Pregnant women or women in lactation;
17. Abnormal clinical laboratory values with clinical significance judged by investigators (for example, if abnormal hepatic function is caused by concurrent other AEDs, the abnormal value within 2 times of normal could be acceptable);
18. Inability of subject to return for scheduled visits or to comply with any other aspect of the protocol.
19. Subjects who, in the opinion of the investigator, were poor medical candidates or pose any other risk for therapy with an investigational drug.
