What is rosuvastatin?

Rosuvastatin (Crestor, Ezallor Sprinkle) is a prescription medication used to treat high cholesterol and prevent heart attacks and strokes.

Rosuvastatin belongs to a class of drugs called statins. It works in two ways. Rosuvastatin works by blocking an enzyme in the liver called HMG-CoA reductase, which leads to the liver making less cholesterol. It also works by increasing the liver's uptake of cholesterol from your blood and its breakdown.

Rosuvastatin comes as a tablet and a capsule. The tablet formulation for rosuvastatin was first approved by the US Food and Drug Administration (FDA) in 2003 under the brand name Crestor. Many generic versions of rosuvastatin tablets have since been approved.

Rosuvastatin is also available as a capsule, which was approved in 2018 under the brand name Ezallor Sprinkle. Adults who can't easily swallow a tablet or capsule can open the capsules and sprinkle the granules onto soft food and eat it. A generic version of the capsules has not been approved.

What is rosuvastatin used for?

Rosuvastatin tablets are used along with diet to:

• lower the level of your “bad” cholesterol (low-density lipoprotein, LDL)
• increase the level of your “good” cholesterol (high-density lipoprotein, HDL)
• lower the level of fat in your blood (triglycerides)
• slow the buildup of fatty deposits (plaque) in the walls of blood vessels

Rosuvastatin tablets are used:

• to treat adults who cannot control their cholesterol levels by diet and exercise alone.
• to treat children 8 to 17 years of age with heterozygous familial hypercholesterolemia (an inherited condition that causes high levels of LDL). Rosuvastatin tablets are not approved for use in children with heterozygous familial hypercholesterolemia younger than 8 years of age.
• to treat children 7 to 17 years of age with homozygous familial hypercholesterolemia (an inherited condition that causes high levels of LDL). Rosuvastatin tablets are not approved for use in children with homozygous familial hypercholesterolemia younger than 7 years of age.
• to reduce the risk of heart attacks and strokes in men 50 years of age and older and women 60 years of age and older who do not have known heart disease but do have certain additional risk factors.

Only Crestor tablets are approved for use in children. Generic versions of rosuvastatin tablets and rosuvastatin capsules are not approved for use in children due to the marketer of Crestor tablets currently having exclusive marketing rights for use of rosuvastatin in this age group.

Rosuvastatin capsules are used in adults along with diet to:

• lower the level of your “bad” cholesterol (LDL).
• lower the level of fat in your blood (triglycerides).

It is not known if rosuvastatin is safe and effective in people who have Fredrickson Type I and V dyslipidemias.
