Crestor (Rosuvastatin)

What is Crestor (Rosuvastatin)?

Crestor is a brand name of the medicine Rosuvastatin. It belongs to a family of medications known as statins. Statins work to lower the levels of cholesterol in the body. If there is too much cholesterol, it can accumulate in the arteries, thereby narrowing them. This reduces blood flow and increases the chances that a clot may get stuck, stopping blood flow and therefore oxygen supply, altogether. This can lead to heart disease, heart attacks and strokes.

How does it work?

Blood tests measure several types of lipids in the blood, low-density lipoproteins (LDL), commonly referred to as bad cholesterol; high-density lipoproteins (HDL) commonly called good cholesterol; and triglycerides, amongst others.

LDLs carry cholesterol out of the liver and into cells. There is more cholesterol than the cells can use and so the leftover cholesterol is deposited in arteries, increasing the risk of heart disease. HDLs carry cholesterol from cells to the liver where it may be metabolized or excreted as waste.

Crestor works to reduce the levels LDLs, increase the levels of HDLs, and so reduce the risk of cardiovascular disease including coronary artery disease. Crestor also reduces the levels of triglycerides.

Statins, including Crestor, work on the enzymes that produce LDLs and are also referred to as HMG-CoA reductase inhibitors because of this action.

In situations where energy is required and there is no sugar or carbohydrate available, the body releases hormones that release triglycerides from fat cells to be used as an energy source. If the level of triglycerides in the body is high, more then necessary, it can cause hardening of the arteries called atherosclerosis. In order to pump blood around the body, arteries rely on their elasticity.

How to use

Crestor comes in tablet form and is taken orally once a day. It comes in 5mg, 10mg and 20mg doses.

It is approved for use in adults and also in children between the ages of 8 and 17 if they have an inherited condition that causes high level of LDLs.
