Lipitor is a brand-name medication used to lower cholesterol levels. Its generic version is Atorvastatin, which is also used to reduce cholesterol levels in the body. According to drugpatentwatch.com [1], the patent for Lipitor expired in 2011, which opened the market for generic versions of the drug. The generic version of Lipitor, Atorvastatin, is much cheaper than the brand-name version. According to goodrx.com [2], the average retail price of Atorvastatin without insurance is around $14.39 for a 30-day supply, while the average retail price of Lipitor without insurance is around $500 for a 30-day supply. This is a significant price difference, and it is due to the fact that generic drugs do not require the same level of research and development as brand-name drugs, which reduces their cost. It is worth noting that the price of Atorvastatin may vary depending on the pharmacy and location. Singlecare.com [3] states that Atorvastatin can be purchased for as low as $2.25 at some pharmacies with a SingleCare card. In conclusion, the generic version of Lipitor, Atorvastatin, is significantly cheaper than the brand-name version, and it can be purchased for as low as $2.25 at some pharmacies with a SingleCare card.
