Current opinion in lipidology, 24(3), 239-245 (2013-04-27)
This review focuses on the current understanding of the physiological mechanisms of action of niacin on lipid metabolism and atherosclerosis. Emerging findings indicate that niacin decreases hepatic triglyceride synthesis and subsequent VLDL/LDL secretion by directly and noncompetitively inhibiting hepatocyte diacylglycerol
James B Kirkland

Through its involvement in over 400 NAD(P)-dependent reactions, niacin status has the potential to influence every area of metabolism. Niacin deficiency has been linked to genomic instability largely through impaired function of the poly ADP-ribose polymerase (PARP) family of enzymes.

Current vascular pharmacology, 9(4), 385-400 (2011-02-15)
Treatment with statins has significantly reduced cardiovascular morbidity and mortality, an effect attributed to both the low-density lipoprotein cholesterol (LDL-C) lowering capacity and the pleiotropic actions of these drugs. However, residual risk remains even after intense LDL-C lowering. Therefore, additional

Current opinion in lipidology, 20(4), 321-326 (2009-06-06)
Nicotinic acid is the most potent treatment clinically available for lowering LDL cholesterol and VLDL cholesterol and raising HDL cholesterol. The strong inverse relationship between coronary heart disease risk and HDL cholesterol at all levels of LDL cholesterol has, therefore

Nicotinic acid has been used for decades to treat dyslipidaemic states. In particular its ability to raise the plasma HDL cholesterol concentration has led to an increased interest in its pharmacological potential. The clinical use of nicotinic acid is somewhat
