Crestor is the brand name for a cholesterol-lowering medication. Its generic name is rosuvastatin [1].
Why is rosuvastatin prescribed?
Rosuvastatin belongs to a class of drugs called statins. It works by blocking an enzyme that the liver needs to produce cholesterol. This reduces the levels of "bad" cholesterol (LDL) and triglycerides in the blood, while increasing "good" cholesterol (HDL) [1]. It is used to treat high cholesterol and triglycerides, and to prevent cardiovascular diseases such as heart attack and stroke in individuals at high risk [1].
When does the patent for Crestor expire?
The primary patent for Crestor expired in the United States in 2011 [2]. This allowed for the introduction of generic versions of rosuvastatin into the market.
Who makes generic rosuvastatin?
Multiple pharmaceutical companies manufacture generic versions of rosuvastatin. These generics are available from various manufacturers, including Teva Pharmaceuticals, Mylan (now Viatris), and others [3].
How do Crestor and its generics compare?
Generic rosuvastatin products are bioequivalent to the brand-name Crestor. This means they contain the same active ingredient (rosuvastatin) and are absorbed by the body at the same rate and to the same extent [4]. Therefore, they are expected to have the same therapeutic effect and safety profile. The primary difference is typically the inactive ingredients, such as fillers or dyes, which do not affect the medication's efficacy or safety [4].
What are the potential side effects of rosuvastatin?
Common side effects of rosuvastatin can include headache, muscle pain, stomach pain, weakness, and nausea [1]. Less common but more serious side effects may involve severe muscle problems (like rhabdomyolysis), liver damage, and an increased risk of diabetes [1]. Patients should discuss any concerns with their healthcare provider.
What other statin medications are available?
Besides rosuvastatin, other commonly prescribed statins include atorvastatin (Lipitor), simvastatin (Zocor), pravastatin (Pravachol), lovastatin (Mevacor), and pitavastatin (Livalo) [5]. Each statin may have slightly different potencies and side effect profiles, and a doctor will choose the most appropriate one based on an individual's needs and medical history [5].
