Chinese medicines do not prevent cerebral infarction, but some of them have the effect of activating blood circulation and removing blood stasis. Patients with high risk factors for cerebral infarction can be given statins, such as atorvastatin; anti-platelet aggregation drugs, such as clopidogrel; and adjustment of blood glucose and blood pressure, such as amlodipine and acarbose. 1. Statin drugs: including atorvastatin, resuvastatin, etc., which have the effect of adjusting blood lipids, stabilizing plaque, and resisting atherosclerosis. 2. Antiplatelet aggregation drugs: representative drugs include aspirin, clopidogrel and so on. If the patient has had a cerebral infarction, the drug can prevent the recurrence of cerebral infarction. 3. Adjustment of blood pressure and blood sugar: For patients with previous diabetes or hypertension, it is recommended to orally take amlodipine benzenesulfonate, timosartan, enalapril and other antihypertensive drugs to adjust blood pressure; use metformin, glimepiride, and various types of insulin to adjust blood sugar, and so on. In addition to the medication prescribed by the doctor, the prevention of cerebral infarction should also include a low-salt, low-fat diet and appropriate daily exercise.
