Rosuvastatin, sold under the trade name Crestor among others, is a statin medication, used to prevent cardiovascular disease in those at high risk and treat abnormal lipids. It is recommended to be used together with dietary changes, exercise, and weight loss. It is taken by mouth.
Common side effects include abdominal pain, nausea, headaches, and muscle pains. Serious side effects may include rhabdomyolysis, liver problems, and diabetes. Use during pregnancy may harm the baby. Like all statins, rosuvastatin works by inhibiting HMG-CoA reductase, an enzyme found in the liver that plays a role in producing cholesterol.
Rosuvastatin was patented in 1991, and approved for medical use in the United States in 2003. It is available as a generic medication. In 2018, it was the 29th most commonly prescribed medication in the United States, with more than 34 million prescriptions.
Effects on cholesterol levels
The effects of rosuvastatin on low-density lipoprotein (LDL) cholesterol are dose-related. Higher doses were more efficacious in improving the lipid profile of patients with hypercholesterolemia than milligram-equivalent doses of atorvastatin and milligram-equivalent or higher doses of simvastatin and pravastatin.
Meta-analysis showed that rosuvastatin is able to modestly increase levels of high-density lipoprotein (HDL) cholesterol as well, as with other statins. A 2014 Cochrane review determined there was good evidence for rosuvastatin lowering non-HDL levels linearly with dose. HDL increases by 7% with no dose effect noted.[medical citation needed]
Side effects and contraindications
Side effects are uncommon. The following side effects should be reported to the prescribing doctor if they persist or get worse:
- joint pain
- memory loss or forgetfulness
The following rare side effects are more serious. Like all statins, rosuvastatin can possibly cause myopathy, rhabdomyolysis. Stop taking rosuvastatin and contact the prescribing doctor if any of these occur:
- muscle pain, tenderness, or weakness
- lack of energy
- chest pain
- jaundice: yellowing of the skin or eyes
- dark colored, or foamy urine
- pain in the upper right part of the abdomen
- extreme tiredness
- unusual bleeding or bruising
- loss of appetite
- flu-like symptoms
- sore throat, chills, or other signs of infection
If any signs of an allergic reaction develop, contact an emergency medical service immediately:
- difficulty breathing or swallowing
- swelling of the face, throat, tongue, lips, eyes, hands, feet, ankles, or lower legs
- numbness or tingling in fingers or toes
Rosuvastatin has multiple contraindications, conditions that warrant withholding treatment with rosuvastatin, including hypersensitivity to rosuvastatin or any component of the formulation, active liver disease, elevation of serum transaminases, pregnancy, or breastfeeding. Rosuvastatin must not be taken while pregnant as it can cause serious harm to the baby. In the case of breastfeeding, it is unknown whether rosuvastatin is passed through breastmilk but, due to the potential of disrupting the infant's lipid metabolism, patients should not breast feed while on rosuvastatin.
The risk of myopathy may be increased in Asian Americans: "Because Asians appear to process the drug differently, half the standard dose can have the same cholesterol-lowering benefit in those patients, though a full dose could increase the risk of side-effects, a study by the drug's manufacturer, AstraZeneca, indicated." Therefore, the lowest dose is recommended in Asians.
As with all statins, there is a concern of rhabdomyolysis, a severe undesired side effect. The U.S. Food and Drug Administration (FDA) has indicated that "it does not appear that the risk [of rhabdomyolysis] is greater with Crestor than with other marketed statins", but has mandated that a warning about this side-effect, as well as a kidney toxicity warning, be added to the product label.
- Coumarin anticoagulants ('blood thinners', e.g. warfarin) can affect the removal of rosuvastatin
- Ciclosporin, colchicine
- Drugs that may decrease the levels or activity of endogenous steroid hormones, e.g. cimetidine, ketoconazole, and spironolactone
- Additional medications for high cholesterol such as clofibrate, fenofibrate, gemfibrozil, and niacin (when taken in lipid-modifying doses of 1 g/day and above)
- Specific protease inhibitors including atazanavir (when taken with ritonavir), lopinavir/ritonavir and simeprevir
- Alcohol intake should be reduced while on rosuvastatin in order to decrease risk of developing liver damage
- Aluminum and magnesium hydroxide antacids should not be taken within two hours of taking rosuvastatin
- Coadministration of rosuvastatin with eluxadoline may increase the risk of rhabdomyolysis and myopathy
Rosuvastatin has structural similarities with most other synthetic statins, e.g., atorvastatin, cerivastatin and pitavastatin, but unlike other statins, rosuvastatin contains sulfur (in sulfonyl functional group).
Crestor is actually a calcium salt of rosuvastatin, i.e. rosuvastatin calcium, in which calcium replaces the hydrogen in the carboxylic acid group on the right of the skeletal formula at the top right of this page.
Mechanism of action
Putative beneficial effects of rosuvastatin therapy on chronic heart failure may be negated by increases in collagen turnover markers as well as a reduction in plasma coenzyme Q10 levels in patients with chronic heart failure.
In a Cochrane systematic review the dose-related magnitude of rosuvastatin on blood lipids was determined. Over the dose range of 1 to 80 mg/day strong linear dose‐related effects were found; total cholesterol was reduced by 22.1% to 44.8%, LDL cholesterol by 31.2% to 61.2%, non-HDL cholesterol by 28.9% to 56.7% and triglycerides by 14.4% to 26.6%.
Absolute bioavailability of rosuvastatin is about 20% and Cmax is reached in 3 to 5 hours; administration with food did not affect the AUC according to the original sponsor submitted clinical study and as per product label. However, a subsequent clinical study has shown a marked reduction in rosuvastatin exposure when administered with food. It is 88% protein bound, mainly to albumin. Fraction absorbed of rosuvastatin is frequently misquoted in the literature as approximately 0.5 (50%) due to a miscalculated hepatic extraction ratio in the original submission package subsequently corrected by the FDA reviewer. It is likely that closer to 0.25 (25%) of the administered dose is absorbed.
Rosuvastatin is metabolized mainly by CYP2C9 and not extensively metabolized; approximately 10% is recovered as metabolite N-desmethyl rosuvastatin. It is excreted in feces (90%) primarily and the elimination half-life is approximately 19 hours.
Society and culture
Under provisions of the Patient Protection and Affordable Care Act (PPACA) in the United States, there is no cost for adults aged 40–75 years for rosuvastatin 5 mg and 10 mg based on United States Preventive Services Task Force (USPSTF) recommendations.
Indications and regulation
Rosuvastatin is approved in the United States for the treatment of high LDL cholesterol (dyslipidemia), total cholesterol (hypercholesterolemia), and/or triglycerides (hypertriglyceridemia). In February 2010, rosuvastatin was approved by the FDA for the primary prevention of cardiovascular events.
Patent protection and generic versions
The main patent protecting rosuvastatin (RE37,314 — due to expire in 2016) was challenged as being an improper reissue of an earlier patent. This challenge was rejected in 2010, confirming protection until 2016.
The drug was billed as a "super-statin" during its clinical development; the claim was that it offers high potency and improved cholesterol reduction compared to rivals in the class. The main competitors to rosuvastatin are atorvastatin and simvastatin. However, people can also combine ezetimibe with either simvastatin or atorvastatin and other agents on their own, for somewhat similar augmented response rates. As of 2006[update] some published information for comparing rosuvastatin, atorvastatin, and ezetimibe/simvastatin results is available, but many of the relevant studies are still[when?] in progress.
First launched in 2003, sales of rosuvastatin were $129 million and $908 million in 2003, and 2004, respectively, with a total patient treatment population of over four million by the end of 2004. Annual cost to the UK National Health Service (NHS) in 2018 for 5–40 mg rosuvastatin daily was £24-40, compared to £10-20 for 20–80 mg simvastatin.
In 2013, it was the fourth-highest selling drug in the United States, accounting for approximately $5.2 billion in sales.
Debate and criticisms
In October 2003, several months after its introduction in Europe, Richard Horton, the editor of the medical journal The Lancet, criticized the way Crestor had been introduced. "AstraZeneca's tactics in marketing its cholesterol-lowering drug, rosuvastatin, raise disturbing questions about how drugs enter clinical practice and what measures exist to protect patients from inadequately investigated medicines," according to his editorial. The Lancet's editorial position is that the data for Crestor's superiority rely too much on extrapolation from the lipid profile data (surrogate end-points) and too little on hard clinical end-points, which are available for other statins that had been on the market longer. The manufacturer responded by stating that few drugs had been tested so successfully on so many patients. In correspondence published in The Lancet, AstraZeneca's CEO Sir Tom McKillop called the editorial "flawed and incorrect" and slammed the journal for making "such an outrageous critique of a serious, well-studied medicine."
In 2004, the consumer interest organization Public Citizen filed a Citizen's Petition with the FDA, asking that Crestor be withdrawn from the US market. On 11 March 2005, the FDA issued a letter to Sidney M. Wolfe, M.D. of Public Citizen both denying the petition and providing an extensive detailed analysis of findings that demonstrated no basis for concerns about rosuvastatin compared with the other statins approved for marketing in the United States.
