Effect of Niacin on Transport of HDL and Relationship to Atherogenic Lipoproteins and Lipolysis

Completed · Not applicable · Has a placebo group

Conditions studied: Dyslipidemias

In brief

This study looks at whether niacin improves reverse cholesterol transport (RCT) in healthy volunteers. 3H-Cholesterol will be used to measure RCT by analyzing changes in the tracer activity in total plasma, lipoproteins, red blood cells (RBCs) and stool. The hypothesis is that niacin augments reverse cholesterol transport.
