Cerebral infarction is ischemic necrosis or softening of limited brain tissues due to impaired blood circulation, ischemia and hypoxia in the brain. Drug therapy for cerebral infarction should choose the corresponding drugs for different periods and different etiologies. The most important medication is anti-platelet aggregation drugs, mainly including aspirin, clopidogrel, cilostazol, tigretol, etc. By inhibiting platelet aggregation and release, these drugs can stop the local thrombus from progressing and expanding, which is the basic medication for the treatment of cerebral infarction. In the case of cerebral infarction caused by atrial fibrillation artery embolism, anticoagulants are often used to prevent re-embolism. The commonly used oral anticoagulant is warfarin, but the INR needs to be monitored when taking this drug (controlled at 2.0~3.0), and there are some new oral anticoagulants such as dabigatran, which do not require INR monitoring. Since patients with cerebral infarction are often accompanied by high-risk factors such as hypertension, diabetes mellitus, hyperlipidemia and hyperhomocysteinemia, these risk factors should be controlled at the same time, and the corresponding antihypertensive drugs, hypoglycemic drugs and lipid-lowering drugs should be applied under the guidance of doctors, among which lipid-lowering drugs usually apply statins, and homocysteine-lowering drugs choose the combination of folic acid, vitamin B6 and vitamin B12. In addition, some Chinese medicine, such as improving circulation, nerve class drugs can also play an auxiliary therapeutic role. Therefore, what drugs are good for specific patients, specific individualized treatment plans should also be selected for the cause and the risk factors of cerebrovascular disease present in patients, and drug treatment is only one aspect of cerebral infarction treatment, and patients should undergo comprehensive treatment including body language rehabilitation under the guidance of doctors.
