Cholesterol Drugs Overview
Drugs used to treat cholesterol are divided into different groups: those that lower LDL cholesterol and those that raise HDL cholesterol or lower triglycerides. It helps to know how the body processes cholesterol in order to understand how cholesterol drugs work.Cholesterol comes from two sources: diet and the liver. When cholesterol and triglycerides from fat are consumed in the diet, they go to the liver, where they are processed, repackaged, and sent back into the bloodstream for distribution by LDLs to cells that need them.
 The many different types of cholesterol drugs might be used to lower bad cholesterol, raise good cholesterol or lower triglycerides. |
Certain cells in the body have what are called receptors on them. These receptors pull cholesterol out of LDLs circulating in the blood and into the cell. When the receptors have taken up all the cholesterol they can manage, the number of receptors shrinks to decrease the amount of cholesterol entering the cell. Any unused LDL cholesterol then remains in the blood, which the LDLs subsequently deposit in the walls of your arteries as plaque.
Drugs that lower LDL cholesterol do so by influencing the balance between production and removal of cholesterol in the body. These drugs work in a fairly predictable fashion. Drugs that raise HDL cholesterol, unfortunately, don't work in a similar predictable fashion. Various other drugs lower triglycerides or other lipoproteins.
One common form of cholesterol medication is statins. Find out what they are and how they work on the next page.
