Lipitor is not a blood pressure medication, but rather a medication used to lower cholesterol levels in the blood [3]. However, according to a study conducted by Pfizer, adding Lipitor to effective blood pressure treatment provided a significant reduction in heart attacks or deaths from heart attacks over five years [2]. It is important to note that Lipitor is not the only medication used to lower cholesterol levels, and there are other options available [1]. It is recommended to consult with a healthcare professional to determine the best medication for an individual's specific health needs and concerns.
