It interferes with how cholesterol is made
Its action is not understood.
It binds to cholesterol and inhibits its production.
It makes the body excrete cholesterol quicker.
The Correct Answer is A
A. Atorvastatin (Lipitor) is a statin medication that works by inhibiting the enzyme HMG-CoA reductase, which plays a key role in cholesterol synthesis in the liver, thereby lowering cholesterol levels.
B. Atorvastatin's mechanism of action is well understood; it is not accurate to say its action is not understood.
C. Atorvastatin does not bind to cholesterol; instead, it inhibits its production in the liver.
