Ages Eligible for Study:   20 Years to 74 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with an episode of cerebral infarction (excluding cardiogenic cerebral thromboembolism) occurring at least 8 days prior to randomization and for whom the clinical course up to randomization is well-documented
  • Patients with a cerebral infarct confirmed by Computed Tomography or Magnetic Resonance Image
  • Body weight : > 50 kg

Exclusion Criteria:

  • Patients with Transient Ischemic Attack occuring after the last episode of cerebral infarction
  • Patients with serious impairment that would hinder detection of new ischemic event
  • Patients with bleeding diathesis, coagulopathy, or hemorrhagic disease
  • Patients with history of intracranial hemorrhage
  • Patients with diabetic retinopathy
  • Hypertensive patients with a persistent increase of blood pressure.
