Lipid-lowering agents, or hypolipidemic agents, are a group of drugs that are used in the treatment of high levels of fats, such as triglycerides and cholesterol, in the blood. Hyperlipidemia (also known as high cholesterol) is the key contributing factors to the development of atherosclerosis (hardening of the arteries), which can lead to stroke and heart attack. This pharmacology lecture covers topics such as pathophysiology of hyperlipidemia; lipids, cholesterol, triglycerides, phospholipids, bile acids, fatty acids, lipoproteins, apolipoproteins, chylomicrons, VLDL, LDL, HDL, lipoprotein lipase, atherosclerosis, and vascular inflammation; mechanism of action of lipid-lowering drugs and their side effects; HMG-CoA reductase inhibitors (statins), nicotinic acid, fibrates, bile acid sequestrants, cholesterol absorption inhibitors, pcsk9 inhibitors, omega 3 fatty acids. Drugs mentioned include; Atorvastatin, Fluvastatin, Lovastatin, Pravastatin, Rosuvastatin, Simvastatin, Niacin, Fenofibrate, Gemfibrozil, Colesevelam, Colestipol, Cholestyramine, Ezetimibe, Evolocumab, Alirocumab, Docosahexaenoic acid (DHA), Eicosapentaenoic acid (EPA), Icosapent ethyl, and Fish oil.
