Abstract
Hypercholesterolemia is commonly associated with diabetes. In combination with diabetes, it puts patients at an increased risk for premature coronary heart disease and atherosclerosis (1). Lipoproteins are developed in one of two ways, via the exogenous or endogenous pathways. LDL cholesterol is a product of VLDL metabolism via the endogenous pathway. Levels of LDL in the plasma are determined by the rate of LDL production and clearance. The LDL production rate from VLDL depends on LDL receptor activity. High receptor activity leads to a decrease in LDL production. Alternatively, low LDL receptor activity leads to an increase in LDL production. These levels of receptors in the liver are regulated by the cholesterol content of the hepatocytes. If the content is low, LDL receptor activity increases to allow for the increased uptake of cholesterol. If the content is higher, LDL receptor activity is decreased, and the LDL uptake is diminished (2). Many medications are available today to manage hypercholesterolemia. The most commonly used are statins, fibrates, bile acid sequestrants, niacin, and dietary cholesterol uptake inhibitors. Less commonly used therapies for cholesterol management include PCSK9 (proprotein convertase subtilisin/kexin type 9) inhibitors, MTP (microsomal triglyceride transfer protein) inhibitors, CETP (cholesteryl ester transfer protein) inhibitors, and apolipoprotein B-100 antisense oligonucleotides. None of these therapies have the same mechanism of action as the novel therapy bempedoic acid (Esperion Therapeutics). Bempedoic acid has been shown to significantly lower LDL cholesterol levels when added to maximally tolerated statin therapies compared with ???
