What do statin drugs like atorvastatin and rosuvastatin do?

• A. Increase LDL and decrease HDL
• B. Cut LDL drastically and reduce total cholesterol and triglycerides, and increase HDL
• C. Have no effect on cholesterol
• D. Only lower triglycerides

Answer: (B)

Statins lower LDL by inhibiting the liver’s HMG-CoA reductase, which reduces cholesterol synthesis. With less cholesterol produced, the liver increases LDL receptor activity and pulls more LDL out of the bloodstream. The result is a substantial drop in LDL cholesterol, a reduction in total cholesterol, and often a decrease in triglycerides with a small rise in HDL. This pattern matches how atorvastatin and rosuvastatin typically affect lipid profiles. They do not increase LDL, they do have an effect on cholesterol, and their main impact isn’t limited to lowering triglycerides.
