Both Rosuvastatin calcium tablets and Atorvastatin calcium tablets belong to the statin class and have the same therapeutic effect, with the class effect being an anti-atherosclerotic effect. The regular dose of 10 mg of Rosuvastatin calcium tablets and the regular treatment of 20 mg of Atorvastatin calcium tablets are both moderate-intensity statins with a lipid-lowering margin of <50%. For high-intensity statins, it means that their lipid-lowering magnitude can be greater than 50% at certain doses, and both Rosuvastatin Calcium Tablets and Atorvastatin Calcium Tablets have anti-atherosclerosis-related effects, which can stabilize or even reverse atherosclerotic plaques, so their therapeutic effects are the same, and there is a little difference between them in terms of side effects and adverse reactions.
