Medication guidance for cerebral infarction is different according to the different periods of infarction. In case of acute cerebral infarction, head and neck vascular examination was done to find the stenosis of the responsible vessels, single-combination antiplatelet therapy or double-combination antiplatelet drugs were selected according to the stenosis Chengdu, commonly used drugs such as aspirin, clopidogrel, and tegretol, in addition to antiplatelet drugs with less side effects such as indobufen. Anti-atherosclerotic drugs, such as statins, are also given orally. three weeks is appropriate for the use of dual antibiotics in patients with NIHSS scores <3, and three months is recommended for patients with ≥70% stenosis of the responsible vessels. In the recovery period of cerebral infarction, the main treatment is to continue to take oral anti-mono platelet drugs and plaque stabilizing drugs. If the patient also has hypertension or diabetes, then both glucose-lowering and antihypertensive therapy should be given to keep blood pressure and blood sugar under more ideal control to reduce the occurrence of another cerebral infarction.
