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. some published information for comparing rosuvastatin, atorvastatin, and ezetimibe/simvastatin results is available, but many of the relevant studies are still in progress.
