What is Crestor?

Crestor is a statin that is used to lower LDL cholesterol and triglycerides, treat inherited high cholesterol, and reduce cardiovascular risk.

Crestor (rosuvastatin) works by blocking HMG-CoA reductase, the rate-limiting enzyme the liver uses to make cholesterol. With cholesterol synthesis reduced, the liver increases its LDL receptors and clears more LDL, or "bad" cholesterol, from the blood. LDL and total cholesterol levels fall, with the maximum reduction usually reached by four weeks.

Crestor gained FDA approval on August 12, 2003. A generic is available under the name rosuvastatin.

Crestor is a prescription medicine that contains a cholesterol-lowering medicine called rosuvastatin. Crestor is used:

  • to reduce the risk of major adverse cardiovascular (CV) events, such as death from cardiovascular disease, heart attack, stroke, or the need for procedures to improve blood flow to the heart called arterial revascularization, in adults at increased risk for these events.
  • along with diet and exercise to lower the level of low-density lipoprotein (LDL-C) cholesterol or "bad" cholesterol: in adults with primary hypercholesterolemia. and slow the buildup of fatty deposits (plaque) in the walls of blood vessels in adults. in adults and children 8 years of age and older with high blood cholesterol due to heterozygous familial hypercholesterolemia (HeFH) (an inherited condition that causes high levels of LDL-C). in adults and children 7 years of age and older with homozygous familial hypercholesterolemia (HoFH) (an inherited condition that causes high levels of LDL-C).
  • along with diet for the treatment of adults with: primary dysbetalipoproteinemia (an inherited condition that causes high levels of cholesterol and fat). hypertriglyceridemia.

It is not known if Crestor is safe and effective in children younger than 8 years of age with HeFH or children younger than 7 years of age with HoFH or in children with other types of hypercholesterolemias (other than HeFH or HoFH).
