  6. Patients should be receiving at least 1 but no more than 2 other AEDs as concomitant medication, and the dosage should be stable for at least 8 weeks before the baseline visit.

Exclusion Criteria:

  1. History of status epilepticus within the last 5 years.
  2. Patients with known significantly impaired renal function and/or severe hepatic impairment to the extent that the protocol dose titration schedule cannot be followed. Note Investigators should consult included SmPC as a guide.
  3. Patients suffering from clinically significant psychiatric illness, psychological or behavioral problems which could interfere with study participation.
  4. Patients with a history (within the last 12 months) of alcohol or drug abuse or dependency.
  5. Patient suffering from any CNS progressive disease that may confound study interpretation, any active CNS infection, demyelinating disease or degenerative neurological disease.
  6. Patients with a significant drug sensitivity or significant allergic reaction to any drug including sulfonamides.
