Cerebral infarction is the occlusion of cerebral arteries due to various reasons, which causes ischemia, hypoxia and necrosis of brain cells and brain tissues, and ultimately causes different degrees of neurological deficit symptoms. Conservative treatment is mainly based on drug therapy to prevent complications. Commonly used drugs: 1, anticoagulant drugs: some patients with cerebral infarction are combined with atrial fibrillation, which is prone to cerebral embolism, and need to be given drugs such as low molecular heparin, warfarin, rivaroxaban, dabigatran ester, etc. 2, antiplatelet drugs: aspirin, clopidogrel, indomethacin, tirofiban and so on, which are the most effective drugs in treating and preventing cerebral thrombosis at present. 3, statin drugs: atorvastatin, risculetin, simvastatin, fluvastatin, floravastatin, and so on. Statin drugs: atorvastatin, resuvastatin, simvastatin, fluvastatin, etc. can slow down the development of cerebral atherosclerosis.4. Drugs to remove free radicals and promote the metabolism of brain cells: edaravone, cytarabine, butylphthalide injection and so on. Most patients, due to the combination of different degrees of neurological deficit symptoms, can be given acupuncture physiotherapy, speech function rehabilitation, exercise therapy and other measures to reduce the occurrence of sequelae after stabilization.
