If simvastatin tablets are used for the treatment of patients with coronary heart disease and cerebrovascular disease, it is recommended that they be taken for life; if they are used only for patients with elevated lipids, the duration of use should be determined on a patient-by-patient basis. Simvastatin tablets belong to the statin class of lipid-lowering drugs, which mainly lower total cholesterol and LDL cholesterol and have the effect of stabilizing plaque, and can be used for patients with coronary heart disease, transient ischemic attack and cerebral infarction to prevent the next attack of cardiovascular disease. If simvastatin tablets are used in patients with simple hyperlipidemia, they can be discontinued after the blood lipids have returned to normal. Also, if a patient develops serious complications such as rhabdomyolysis while taking the drug, the drug should be discontinued immediately. In addition, patients taking simvastatin tablets should eat a light diet and avoid eating too oily and spicy foods.
