Question

Atorvastatin (Lipitor) is a statin that can be used to lower blood cholesterol levels by

1. binding exogenous cholesterol and excreting it in the feces.
2. increasing excretion by activating enzymes within the hepatic system.
3. preventing dietary absorption within the GI tract.
4. inhibiting an enzyme that is essential for cholesterol synthesis

Answer 1

Atorvastatin (Lipitor) is a statin that lowers blood cholesterol levels by inhibiting an enzyme that is essential for cholesterol synthesis.

Step-by-step explanation:

Atorvastatin (Lipitor) is a statin that lowers blood cholesterol levels by inhibiting an enzyme that is essential for cholesterol synthesis. Statins are a class of drugs that reduce cholesterol levels in the body by targeting the enzyme HMG-CoA reductase, which is responsible for synthesizing cholesterol from lipids. By inhibiting this enzyme, statins effectively decrease the levels of cholesterol synthesized in the body.
