It is possible to obtain generic versions of Lipitor, the brand-name drug used to treat high cholesterol, at many pharmacies. Lipitor's active ingredient is atorvastatin, and generic atorvastatin has been available in the U.S. market since November 2011 [1].

The availability of generic Lipitor is supported by the expiration of Pfizer's patent on the drug. According to DrugPatentWatch.com, Pfizer's patent for atorvastatin calcium, the active ingredient in Lipitor, expired in November 2011 [1]. After a patent expires, other manufacturers can produce and sell generic versions of the drug, leading to increased availability and typically lower costs for consumers.

However, it is essential to note that the availability of generic Lipitor may vary depending on the pharmacy and its suppliers. Some pharmacies might carry generic atorvastatin from specific manufacturers, while others might offer a variety of options. Additionally, the cost of generic Lipitor can differ among pharmacies due to factors such as pricing agreements and location [2].

In summary, generic Lipitor (atorvastatin) is available at many pharmacies following the expiration of Pfizer's patent in November 2011. However, the availability and cost of generic Lipitor may vary among pharmacies.
