Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], Lipitor is a statin drug that works by blocking an enzyme responsible for producing cholesterol in the liver. This medication has been used for many years to reduce the risk of heart attack, stroke, and other cardiovascular diseases.

While Lipitor does not directly affect blood pressure, it has been shown to have a positive effect when combined with blood pressure medication. According to a press release by Pfizer [3], adding Lipitor early to effective blood pressure treatment provided a significant reduction in heart attacks or deaths from heart attacks over five years. The study 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, it is important to note that Lipitor can have side effects. Medical News Today [2] reports that common side effects of Lipitor include muscle pain, weakness, and tenderness, and that in rare cases, it can cause serious side effects such as liver damage, kidney problems, and diabetes.

In conclusion, Lipitor is a medication used to lower cholesterol levels and reduce the risk of cardiovascular diseases. While it does not directly affect blood pressure, it has been shown to have a positive effect when combined with blood pressure medication. However, Lipitor can have side effects, and patients should discuss the risks and benefits of taking this medication with their healthcare provider.
