For the choice of lipid-lowering drugs, different drugs should be selected according to the type and degree of lipid elevation, and the focus of each drug is different, so we cannot say what drugs are good or bad. Lipid-lowering drugs can be broadly divided into the following categories: a. Hydroxymethylglutaryl coenzyme A reductase inhibitors, i.e., statins, representing drugs such as simvastatin, atorvastatin and rasulvastatin, which are mainly used to reduce cholesterol levels and also have the effect of lowering triglycerides. Bile acid chelators, mainly used to lower cholesterol and LDL-C, have no lowering effect on triglycerides or have a slight elevation effect. Phenoxyaromatic acid and its derivatives, i.e., beta drugs, are mainly used to lower triglycerides, and also have the effect of lowering cholesterol, which is weak. Fourth, niacin and its derivatives, mainly used to lower triglycerides and also has a cholesterol-lowering effect. V. Polyene-based fatty acids, mainly fish oil preparations. Sixth, antioxidants, such as probucol, can be used for anti-atherosclerosis, delay the role of diabetic nephropathy, etc.
