Generic Name: rosuvastatin
Brand Name: Crestor
Drug Class: HMG-CoA Reductase Inhibitors, Lipid-Lowering Agents, Statins
What is rosuvastatin, and what is it used for?
Rosuvastatin is an oral drug for lowering blood cholesterol levels. Rosuvastatin is used for the reduction of blood total cholesterol, HDL cholesterol, and triglyceride levels, and to increase HDL cholesterol levels.
Rosuvastatin also is used for reducing the risk of heart attacks, stroke, and arterial revascularization procedures in patients without clinically evident coronary heart disease but with multiple risk factors for heart disease.
It belongs to a class of drugs called HMG-CoA reductase inhibitors, more commonly referred to as "statins." Other drugs in this class include
- simvastatin (Zocor),
- lovastatin (Mevacor),
- pravastatin (Pravachol),
- atorvastatin (Lipitor) and
- fluvastatin (Lescol).
These drugs reduce cholesterol levels by inhibiting HMG-CoA reductase, an enzyme that produces cholesterol in the liver. Rosuvastatin and other statins lower blood total cholesterol as well as blood LDL cholesterol levels. LDL cholesterol is the "bad" type of cholesterol that increases the risk of coronary artery disease (atherosclerosis) and heart attacks. Lowering LDL cholesterol levels slows the progression of coronary artery disease and may even reverse it. Statins also increase HDL cholesterol, the "good" type of cholesterol, and reduce triglycerides.
Scientists have discovered that in addition to atherosclerosis, inflammation of the coronary arteries may also contribute to the development of heart attacks. The presence of inflammation can be determined by measuring a chemical in the blood called highly sensitive, C-reactive protein (Hs-CRP). Moreover, Hs-CRP can be used to predict the occurrence of heart attacks, strokes and death. Hs-CRP is, in fact, a better predictor of the risk for heart attacks than LDL cholesterol.
Scientists have found that statins reduce the level of Hs-CRP in the body, presumably by reducing inflammation in the coronary arteries, and this may be another mechanism through which statins prevent heart attacks, strokes, and death. More research needs to be conducted, however, to confirm the importance of inflammation and the mechanisms through which statins work.Rosuvastatin was approved by the FDA in August 2003.
What are the side effects of rosuvastatin?
The most common side effects of rosuvastatin are:
- diarrhea and
- muscle pain.
Other important side effects include:
- post-marketing reports of memory loss,
- confusion, and
- memory impairment.
Symptoms may start one day to years after starting treatment and resolve within a median of three weeks after stopping the statin.
What is the dosage for rosuvastatin?
- The starting dose for most adults is 5 mg once daily.
- The maximum dose is 40 mg daily, and this dose should be reserved for patients who do not adequately respond to a 20 mg dose.
Which drugs or supplements interact with rosuvastatin?
- When administered with cyclosporine, the blood level of rosuvastatin increases seven fold, and this could increase the side effects of rosuvastatin.
- Rosuvastatin increases the action of the blood thinner warfarin and could increase the risk of bleeding from warfarin.
- Antacids reduce the absorption of rosuvastatin and should be administered two hours after rosuvastatin.
- The use of rosuvastatin with nicotinic acid, gemfibrozil (Lopid), or other drugs that may cause liver or muscle injury may increase the incidence of the muscle injury.
Is rosuvastatin safe to take if I'm pregnant or breastfeeding?
- Statins should not be used by pregnant women because there is a high risk of harm to the fetus.
- There is no information on whether rosuvastatin is excreted in human milk.
What else should I know about rosuvastatin?

What preparations of rosuvastatin are available?
- Tablets: 5, 10, 20, and 40 mg
How should I keep rosuvastatin stored?

Cholesterol is a waxy substance found in all the cells of the body. It is a type of fat that is produced by the liver. Cholesterol also comes from animal-derived foods, such as meat and dairy products.
High cholesterol and triglyceride levels increase the risk of cardiovascular disease. Getting your cholesterol and triglyceride levels in an optimal range will help protect your heart and blood vessels. Cholesterol management may include lifestyle interventions (diet and exercise) as well as medications to get your total cholesterol, LDL, HDL, and triglycerides in an optimal range.
Lower Cholesterol Levels with Diet and Medications
High-density lipoprotein (HDL) cholesterol is considered "good" cholesterol because it actually works to keep the LDL or "bad" cholesterol from building up in your arteries. Foods like extra lean meats, skim milk, and vegetable-based "butter-like" substitutes may help decrease LDL levels in the bloodstream.
A stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic). Symptoms of a stroke may include weakness, numbness, double vision or vision loss, confusion, vertigo, difficulty speaking, or understanding speech. A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
Fatty Liver (NASH)
Nonalcoholic fatty liver disease or NASH occurs due to the accumulation of abnormal amounts of fat within the liver. Fatty liver most likely caused by obesity and diabetes. Symptoms of fatty liver disease are primarily the complications of cirrhosis of the liver; and may include mental changes, liver cancer, the accumulation of fluid in the body (ascites, edema), and gastrointestinal bleeding. Treatment for fatty liver includes avoiding certain foods and alcohol. Exercise, weight loss, bariatric surgery, and liver transplantation are treatments for fatty liver disease.

HDL vs. LDL Cholesterol (Good and Bad)
HDL (high-density lipoprotein), or the "good" cholesterol, and LDL (low-density lipoprotein), or the "bad" cholesterol, are lipoproteins that carry cholesterol through the veins and arteries of the body. HDL and LDL combined, is your "total" blood cholesterol. The difference between the two are that high levels of the "good," or HDL cholesterol, may protect against narrowing of the blood vessels in the body, which protects you against heart attack, stroke, and other cardiovascular diseases. But high levels of LDL, or the "bad" cholesterol, may worsen the narrowing of the blood vessels in the body, which puts you at a greater risk of stroke, heart attack, and cardiovascular diseases, some of which are life threatening.Triglycerides are found in body fat and from the fats you eat.
