1. Types of commonly used lipid-regulating drugs 1. Statins: They are the most important and widely used lipid-lowering drugs in clinical practice. Including: lovastatin, simvastatin, pravastatin, fluvastatin, atorvastatin, risulfastatin. 2.Fibrates: fenofibrate, benzofibrate, gemfibrozil, clobetine. The latter two are rarely used clinically due to the large side effects. 3.Niacin: niacin, acipimox, etc. 4.Bile acid chelating agent (resin type): abbreviated bile amine, descending bile nin. 5.Ezetimibe: intestinal cholesterol absorption inhibitor. Commonly used dose is 10mg once a day. 6.Probacol: the common dose is 0.5g, taken orally twice a day. 7.n-3 fatty acid preparation: EPA, DHA, the main component of sea fish oil. It can lower TG and raise HDL-C, and has no effect on TC and LDL-C. The commonly used dose is 0.5-1g, taken orally 3 times a day. Second, the selection of lipid-regulating drugs should be based on the patient’s dyslipidemia typology, the mechanism of lipid-regulating action of drugs and other characteristics of drug action. 1, hypercholesterolemia: statins are preferred, if statin alone cannot achieve the therapeutic goal, ezetimibe can be added. 2.Hypertriglyceridemia: Bets and niacin are preferred, and n-fatty acid preparations can also be used. 3.Mixed hyperlipidemia: if TC and LDL-C are mainly increased, statins are preferred; if TG is mainly increased, betablockers are preferred; if TC, LDL-C and TG are significantly increased, combined medication can be considered. The combination of statins and ezetimibe can enhance the lipid-lowering effect without increasing the side effects. The combination of statins with fibrates or nicotinic acid can significantly improve the lipid profile, but the possibility of increased myopathy and hepatotoxicity should be given high priority. Mild mixed hyperlipidemia can be treated with a combination of statins and n-3 fatty acid preparations. Note: TG: triglycerides TC: cholesterol LDL-C: low-density lipoprotein HDL-C: high-density lipoprotein
