Strong epidemiological evidence linked elevated levels of low-density lipoprotein cholesterol (LDL-C) to risk of atherosclerotic heart disease. As a consequence, LDL-C lowering has been the main goal of therapy to reduce cardiovascular risk for the past few decades and hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) have become some of the most commonly prescribed drugs. In spite of the proven efficacy of these drugs, statins reduce cardiovascular events by only 30-40%. Epidemiological analyses clearly indicate that a significant portion of risk is linked to other particles such as low high-density lipoprotein cholesterol (HDL-C), high triglycerides and others. Furthermore, several quantitative coronary angiography studies showing regression of atherosclerosis and reduction in subsequent events utilized a combination of drugs effective on LDL-C as well as other lipoproteins. Hence, several new drugs are being investigated that affect more than the traditional LDL-C pathways. In this article, we review lipoprotein-modifying agents that have either been recently released, or are still in various phases of development. They include agents that reduce LDL-C levels by mechanisms other than HMG-CoA inhibition (such as cholesterol absorption inhibitors, Acyl-CoA cholesterol acyl transferase inhibitors, sterol-regulating binding protein cleavage activating protein ligands, microsomal triglyceride transfer protein inhibitors, LDL-C receptor activators and farnesoid X receptor antagonists) and agents that raise HDL-C cholesterol or improve cholesterol efflux (such as cholesterol ester transfer protein inhibitors, retinoid X receptor selective agonists, specific peroxisome proliferator-activated receptor (PPAR) agonists and estrogen like compounds).
