Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood. Atorvastatin is available as a generic medication, which is usually less expensive than the brand-name version.

According to DrugPatentWatch [1], the first generic version of Lipitor was approved by the FDA in November 2011. Since then, several pharmaceutical companies have produced generic versions of atorvastatin. Some of the generic versions available include:

- Atorvastatin calcium, produced by Apotex Corp, Aurobindo Pharma, Dr. Reddy's Laboratories, Mylan Pharmaceuticals, and Teva Pharmaceuticals.
- Atorvastatin calcium tablets, produced by Watson Laboratories and Lupin Pharmaceuticals.
- Atorvastatin calcium tablets (film-coated), produced by Accord Healthcare, Actavis Elizabeth, and Par Pharmaceutical.

It's important to note that while generic medications are required to have the same active ingredient as the brand-name medication, they may have different inactive ingredients, which can affect how the medication is absorbed and how well it works for some people.

According to GoodRx [2], the cost of atorvastatin can vary depending on the pharmacy and the specific generic version of the medication. As of August 2021, the lowest price for a 30-day supply of atorvastatin (generic Lipitor) was $3.30 at some pharmacies. GoodRx also offers coupons and discounts for atorvastatin, which can help reduce the cost further.

In conclusion, there are several generic options available for atorvastatin, which is the generic version of Lipitor. The availability and cost of these options may vary depending on the pharmacy and the specific generic version of the medication. It's important to talk to a healthcare provider or pharmacist to determine the best option for individual needs.
