Choice of Hypolipidemic Agents

Cholesterol is necessary for human body as a component in cell wall's structure. But in excess, cholesterol can be dangerous. Cholesterol could create a plaque on vascular wall, thus obstructing vessel's caliber, and increases the risk of cardiovascular diseases.

In our body, cholesterol goes through circulation with the aid of lipoprotein (transporter protein for lipids in blood circulation). There are some kinds of lipoprotein, with the main kinds are LDL (low-density lipoprotein) and HDL (high -density lipoprotein). LDL is needed to take cholesterol from liver to peripheral tissue and vessels. If LDL exists in high level, atheroma could be formed. Reversely, HDL takes cholesterol from peripheral tissue back to the liver.
