Lipitor, also known as atorvastatin, is a medication that is used to treat high cholesterol levels. According to Drug Patent Watch [1], Lipitor works by blocking the enzyme that produces cholesterol in the liver. This medication is not known to have a direct impact on blood pressure.

However, Medical News Today [2] notes that Lipitor may interact with certain blood pressure medications, such as amlodipine and diltiazem. These interactions may cause an increased risk of side effects, such as muscle pain and weakness.

Despite this potential interaction, Pfizer [3] conducted a study that found adding Lipitor to an effective blood pressure treatment plan may provide a significant reduction in heart attacks or deaths from heart attacks over five years. This study suggests that Lipitor may have a positive impact on overall cardiovascular health when used in conjunction with blood pressure medication.

In summary, Lipitor is not known to have a direct impact on blood pressure, but it may interact with certain blood pressure medications. However, adding Lipitor to an effective blood pressure treatment plan may provide benefits for overall cardiovascular health. Patients should always consult with their healthcare provider before starting or changing any medications.
