Lipitor, also known as atorvastatin, is a commonly prescribed medication used to lower cholesterol levels in the body. One study [2] found that Lipitor was effective in reducing low-density lipoprotein (LDL) cholesterol levels in patients with hypercholesterolemia. However, patient compliance with medication is crucial for the success of any treatment.

According to Drug Patent Watch [1], Lipitor was one of the most prescribed medications in the United States from 2002 to 2012. Despite its effectiveness, some studies suggest that patient compliance with Lipitor may be an issue.

A study published in the Journal of Managed Care Pharmacy [3] found that adherence to Lipitor decreased over time, with only 53.4% of patients continuing to take the medication after six months. The study also found that patients who were older, had a higher income, and had a history of cardiovascular disease were more likely to adhere to the medication.

Another study published in the Journal of Clinical Lipidology [2] found that patient education and counseling improved adherence to Lipitor. The study recommended that healthcare providers should educate patients about the importance of taking Lipitor as prescribed and the potential benefits of the medication.

In conclusion, while Lipitor has been shown to be effective in reducing cholesterol levels, patient compliance with the medication may be an issue. Healthcare providers should educate patients about the importance of taking Lipitor as prescribed and the potential benefits of the medication.
