Niacin (nicotinic acid) is the broad-spectrum lipid drug, which lowers the concentration of all atherogenic plasma lipids/lipoproteins and at the same time raises the levels of the protective HDL (high-density lipoprotein). Niaspan™ is a prolonged release (PR) formulation of niacin, which has considerable advantages over both immediate release (IR) and slow release (SR) formulations of this drug. The major early side effect of IR niacin, the flush, is reduced with Niaspan™. The hepatotoxic effects with SR niacin are not present with Niaspan™. It is suitable for once daily prescription at bedtime. Niaspan™ is effective as monotherapy and in combination with other lipid-lowering drugs such as statins and fibrates. It is particularly useful for treatment of the dyslipidaemia of type 2 diabetes, where IR but not PR niacin may deteriorate the diabetic condition. Overall, niacin, now available as the well-tolerable drug formulation Niaspan™, is the unique broad-spectrum lipid drug for the prevention and treatment of clinical atherosclerosis.
