Lipitor is a brand-name drug that contains the active ingredient atorvastatin, which is used to lower cholesterol levels in the blood. The patent for Lipitor expired in 2011, allowing other companies to produce generic versions of the drug [1]. Generic drugs are typically more affordable than brand-name drugs because they do not have to go through the same development and marketing costs as brand-name drugs [2].

According to GoodRx, a website that compares drug prices, there are several generic versions of atorvastatin available that are significantly cheaper than Lipitor. For example, the generic version of atorvastatin can cost as little as $4 for a 30-day supply, while Lipitor can cost over $300 for the same amount [2].

The New York Times reported in 2011 that Pfizer, the manufacturer of Lipitor, had negotiated deals with several large pharmacy benefit managers to delay the introduction of generic versions of the drug. However, these agreements eventually expired, and generic versions of atorvastatin are now widely available [3].

In conclusion, generic versions of atorvastatin are generally more affordable than Lipitor. Patients who are prescribed atorvastatin should talk to their doctor or pharmacist about the most cost-effective options available to them.
