Lipitor is a medication used to lower cholesterol levels in the blood. It belongs to a class of drugs called statins and is the brand name for the drug atorvastatin [1]. Lipitor works by blocking an enzyme that the liver uses to produce cholesterol, thus reducing the amount of cholesterol in the bloodstream [2].

Lipitor is not a blood pressure medication, and it is not used to treat high blood pressure. However, a study conducted by Pfizer found that adding Lipitor early to effective blood pressure treatment provided a significant reduction in heart attacks or deaths from heart attacks over five years [3].

When it comes to comparing Lipitor to other blood pressure medications, it is important to note that Lipitor is not a blood pressure medication and is not used to treat high blood pressure. Therefore, it cannot be directly compared to other blood pressure medications.

In summary, Lipitor is a medication used to lower cholesterol levels in the blood, and it is not a blood pressure medication. While a study conducted by Pfizer found that adding Lipitor early to effective blood pressure treatment provided a significant reduction in heart attacks or deaths from heart attacks over five years, Lipitor cannot be directly compared to other blood pressure medications [1][2][3].
