Final answer:
Lipitor is not an antihypertensive medication but a statin used to lower cholesterol levels.
Step-by-step explanation:
The statement that Lipitor is a powerful antihypertensive medication is False.
Lipitor, also known as atorvastatin, is actually a statin medication used to lower cholesterol levels, not to treat hypertension (high blood pressure). Statins work by inhibiting the enzyme HMG-CoA reductase, which is responsible for synthesizing cholesterol in the body. By reducing cholesterol levels, statins help prevent cardiovascular diseases, such as heart attacks and strokes.
