    2. Abnormal and clinically relevant ECG tracing.
  6. Donation or loss of a significant volume of blood or plasma (> 450 mL) within 28 days prior to the initial dose of study medication.
  7. Subjects who have received an investigational drug within 30 days prior to the initial dose of study medication.
  8. Allergy or hypersensitivity to valproic acid or any other related products.
