Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. It is often prescribed to people who have high blood pressure and are at risk of heart disease. 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 [3]. However, it is important to note that Lipitor can have side effects, such as muscle pain, liver damage, and digestive problems [2]. It is also important to consider potential drug interactions when taking Lipitor with other medications, including blood pressure medication. According to Drug Patent Watch, there are no known drug interactions between Lipitor and blood pressure medication [1]. However, it is always important to consult with a healthcare provider before starting any new medication or making changes to an existing medication regimen.
