Rosuvastatin belongs to the class of medications called Statins (also known as HMG-CoA reductase inhibitors). Statins lower the amount of ‘bad cholesterol’ (low density lipoprotein or LDL-cholesterol) and ‘fat’ (triglyceride) in the blood as well as increase the amount of ‘good cholesterol’ (high density lipoprotein or HDL-cholesterol).
High ‘bad cholesterol’ levels can cause your blood vessels to clog up and lead to chest pain (angina), heart attack or stroke. Hence, statins may reduce your risk for heart attack and stroke.
