How do HMG-CoA reductase inhibitors, such as atorvastatin and simvastatin, work to lower blood lipids?
Explanation
HMG-CoA reductase inhibitors, commonly known as statins, are a cornerstone of lipid-lowering therapy. They function by blocking HMG-CoA reductase, a key enzyme in the body's pathway for producing cholesterol.
