Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. However, there is some evidence that suggests that it may also have an effect on blood pressure.

According to a study published in the American Journal of Hypertension [3], adding Lipitor to existing blood pressure treatment resulted in a significant reduction in heart attacks or deaths from heart attacks over five years. The study found that adding Lipitor to the treatment regimen of patients with high blood pressure and normal cholesterol levels resulted in a 36% reduction in the risk of heart attacks or deaths from heart attacks.

While the study suggests that Lipitor may have a positive effect on blood pressure, it is important to note that this was not the primary focus of the study. Additionally, the study only looked at patients with high blood pressure and normal cholesterol levels, so it is unclear whether Lipitor would have the same effect on patients with high blood pressure and high cholesterol levels.

Overall, while there is some evidence to suggest that Lipitor may have a positive effect on blood pressure, more research is needed to fully understand the relationship between the medication and blood pressure.
