Lipitor is a brand-name medication that contains the active ingredient atorvastatin, which is a type of statin used to lower cholesterol levels. According to the drug patent watch [1], Lipitor was first approved by the FDA in 1996 and its patent expired in 2011. As of 2019, Pfizer's sales of Lipitor had decreased significantly, but it remained one of the most widely prescribed medications in the United States.

When compared to other statins, Lipitor is generally more expensive. According to GoodRx [2], the average retail price for a 30-day supply of Lipitor 20mg is around $300, while the average retail price for a 30-day supply of simvastatin (a generic statin) is around $10. However, it is important to note that the cost of medication can vary depending on factors such as insurance coverage and pharmacy location.

In conclusion, Lipitor is generally more expensive than other statins, but its effectiveness and tolerability may vary from person to person. Patients should consult with their healthcare provider to determine the best medication for their individual needs and budget.
