Lipitor is a brand name drug that contains the active ingredient atorvastatin, which belongs to a class of drugs called statins. Statins are used to lower cholesterol levels and reduce the risk of heart attack and stroke [2]. According to DrugPatentWatch, the patent for Lipitor expired in November 2011, which allowed other drug manufacturers to produce generic versions of atorvastatin [1].

The cost difference between Lipitor and its generic versions can be significant. GoodRx provides a comparison chart of statins and their generic equivalents, including atorvastatin. According to the chart, the average retail price for a 30-day supply of Lipitor is $339.32, while the average retail price for a 30-day supply of atorvastatin is $9.00 [3].

It is important to note that the cost of prescription drugs can vary depending on several factors, such as insurance coverage, pharmacy location, and dosage strength. Patients should always consult with their healthcare provider and pharmacist to determine the most cost-effective option for their individual needs.

In conclusion, the cost difference between Lipitor and generic atorvastatin can be significant, with the generic version being significantly cheaper. However, the actual cost may vary depending on various factors, and patients should consult with their healthcare provider and pharmacist to determine the most cost-effective option for their individual needs.
