Ozagrel sodium (ozagrel), a thromboxane A2 synthesis inhibitor, is used for patients with noncardioembolic stroke in China, Korea, and Japan. In the Japanese guideline for managing patients with acute ischemic stroke, it is recommended to start administering ozagrel for patients with noncardioembolic ischemic stroke, including atherothrombotic stroke and lacunar infarction, within 5 days after onset, using a dose of 80mg twice a day for 14 days[1-2].
