Exclusion Criteria:

• History of non-epileptic seizures (metabolic, structural, or pseudoseizures).
• History of status epilepticus while on any antiepileptic medication.

• The subject has a clinically significant (e.g., cancerous, unstable, progressive, functionally disabling, or infectious) medical condition that would interfere with the ability to complete the study or that might interfere with the absorption, distribution, metabolism, and/or excretion of drugs.
• Subjects with impaired hepatic function [ALT (Alanine aminotransferase), AST (Aspartate aminotransferase) =3 times the upper limit of normal] or any clinically significant laboratory abnormality that, in the opinion of the investigator, would increase the risk of participation or interfere with the interpretatio of the study results.
