Question 4

Which of the following mechanisms best describes the action of statin drugs in lowering cholesterol levels?

Accepted Answer

B. Inhibiting HMG-CoA reductase enzyme — Statins, such as atorvastatin and simvastatin, are competitive inhibitors of HMG-CoA reductase, the rate-limiting enzyme in cholesterol biosynthesis in the liver. This inhibition leads to a decrease in endogenous cholesterol production, which in turn upregulates LDL receptors on hepatocytes, increasing LDL clearance from the blood. Increasing bile acid excretion is the mechanism of bile acid sequestrants, activating lipoprotein lipase is primarily for fibrates, and blocking cholesterol absorption is for ezetimibe.

A. Increasing bile acid excretion in the feces
