Brief Summary:
Nicotinic acid (Niacin) has been used for many years for the treatment of dyslipidemia. Indeed Niacin decreases triglycerides (TG) and low density lipoprotein cholesterol (LDL-c) but more importantly increases high density lipoprotein cholesterol (HDL-c). Although the drug has been used for so long, its precise mechanism of action remains elusive. The aim of this study was to characterise the metabolic changes induced by 8 week treatment with Niacin in dyslipidemic, overweight patients. The importance of the inhibition of lipolysis on the overall lipid effects of niacin will be studied. In order to get a very comprehensive view of all metabolic activities of niacin, this study will investigate the potential effects of niacin on Glucose metabolism, lipid and lipoprotein turnover, quantitative changes in lipoproteins and key enzymes involved in lipid metabolism.
Detailed Description:
24 patients will be included in a double blind placebo controlled cross-over 8 week study comparing placebo to Niaspan (a long release formulation of niacin). In order to prevent any drop out linked to the flushing side effect of niacin, patient will take aspirin (300mg) prior to treatment throughout the study duration. The study will include at start and end of each arm, a full lipoproteins quantification as well as a measure of enzymes involved in lipid metabolism. On day 42 and 56 of each period, after an administration of either placebo or 500mg of immediate release niacin respectively, changes in plasma free fatty acid levels will be measured for 8hours in order to assess potential loss of activity of niacin over time upon chronic treatment with niaspan. Half of the patient will have an exploration of their glucose metabolism using hyperinsulinic clamp technique, whereas in the other half a metabolic turnover study using stable isotopes will focus on their lipoproteins, triglycerides and cholesterol handling. These explorations will be done at the end of each treatment period.
