Simvastatin does not treat cerebral infarction disease, but it can be used for endothelial protection, lipid lowering, and plaque stabilization during the acute phase of cerebral infarction. Simvastatin mainly reduces the cholesterol and LDL levels in the patient’s blood. Although it is not a cure for cerebral infarction, it has a very positive effect on the acute phase of cerebral infarction or the prevention of cerebral infarction disease. The treatment of cerebral infarction disease mainly involves the use of blood-activating drugs to improve blood circulation in the brain and improve the symptoms of neurological deficits in patients. Special drugs often used in clinical practice, such as thrombolysis with rt-PA or urokinase, anticoagulation with argatroban, fibrin-lowering with bactrim, antiplatelet aggregation with aspirin, clopidogrel hydrogen sulfate, giving cerebral protection with edaravone, butalbital sedation, the above are the basic drugs used in the treatment of cerebrovascular disease.
