Dizziness and insufficient blood supply to the brain need to be based on the cause of the disease, choose the corresponding drug treatment, the common causes of the disease are mainly cervical spondylosis, diabetes, hypertension, high blood pressure, high blood fat, atherosclerosis caused by the carotid plaque, etc., and the common drugs are mainly akaposan, nifedipine, atorvastatin, methylcobalamin and so on. 1. Cervical spondylosis: usually patients with cervical spondylosis will cause blood supply vessels in the brain to be compressed, thus reducing the amount of blood flowing to the brain, making the brain ischemia, hypoxia and dizziness; you can follow the doctor’s instructions to choose methylcobalamin, glutamine and other drugs affecting the nerves to be treated, and if necessary, physiotherapy or surgery to correct the symptoms of cervical spondylosis. 2. Atherosclerosis and other diseases may lead to carotid plaque, so that the cerebral arteries are narrowed or occluded, and the brain blood flow changes and causes dizziness, generally taking aspirin and other antiplatelet aggregation drugs, atorvastatin calcium and other modulation of stabilizing plaque drugs, methylcobalamin and other nutritive nerve drugs, and if necessary, feasible cerebral vascular stenting to improve the cerebral blood supply situation. According to the cause of cerebral atherosclerosis, such as diabetes can choose acarbose, glibenclamide, metformin and other hypoglycemic drugs; hypertension can choose nifedipine, hydrochlorothiazide, amlodipine, enalapril, valsartan and other blood pressure lowering drugs; hyperlipidemia, large arterial atherosclerosis and other diseases, can choose atorvastatin, resuvastatin and other blood fat-lowering drug therapy. When the symptoms of dizziness, it is recommended to go to the hospital in a timely manner, early standardized treatment, drugs need to be used under the guidance of a physician.
