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.
