Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. According to Drug Patent Watch [1], Lipitor works by blocking an enzyme that is responsible for producing cholesterol in the liver. It is not specifically designed to lower blood pressure, but studies have shown that it may have some effect on blood pressure.

According to Medical News Today [2], Lipitor can cause a number of side effects, including headaches, muscle pain, and weakness. It can also cause liver damage in some cases. However, the article does not mention anything about Lipitor lowering blood pressure.

A press release from Pfizer [3] states that adding Lipitor to effective blood pressure treatment can provide a significant reduction in heart attacks or deaths from heart attacks over five years. The study mentioned in the press release found that patients who took Lipitor in addition to their blood pressure medication had a 36% reduction in the risk of heart attack or death from heart attack compared to those who only took blood pressure medication. However, the press release does not provide any information about how Lipitor may affect blood pressure specifically.

In conclusion, while Lipitor is not specifically designed to lower blood pressure, it may have some effect on blood pressure and can be used in conjunction with blood pressure medication to reduce the risk of heart attack or death from heart attack. However, Lipitor can also cause a number of side effects, and patients should consult with their doctor before taking any new medication.
