Atorvastatin belongs to the group HMG-CoA reductase inhibitor thsat inhibits cholesterol synthesis in the liver by inhibiting the rate-inhibiting enzyme HMG-CoA reductase. Consequently there is a ncrease in the number of LDL receptors onthe liver surface, that take up the excess circulating LDL-C (rich with cholesterol ) in the blood.
This leads to decreased levels of LDL-C in blood Niacin has diverse actions affecting lipid metabolism. It however does not cholesterol synthesis. Primary effects is to decrease production of VLDL by inhibiting liupolysis. This inhibits the delivery of fatty acids to liver and consequently there is a decreased triglyceride and VLDL synthesis.
The decrease in LDL levels is primarily due to decreased VLDL production and also by improving the activity of lipoprotein lipase. It also elevates HDL by promoting synthesis of apolipoprotein precursors that produce HDL particles.Of the entire lipid lowering agents, niacin is the most effective agent in elevating HDL levels.
