Lipitor is a brand-name drug that is used to lower cholesterol levels in the blood. It was first approved by the FDA in 1996 and became one of the most widely prescribed drugs in the world. However, the patent for Lipitor expired in 2011, which allowed other companies to produce generic versions of the drug.

According to DrugPatentWatch [1], there are currently several generic versions of Lipitor available on the market. These generics are produced by different companies and are sold under different names, such as Atorvastatin Calcium and Atorvastatin Calcium Trihydrate. The prices of these generics can vary depending on the pharmacy and the location, but they are generally much cheaper than the brand-name drug.

In fact, according to a report by STAT News [2], the cost of generic Lipitor can be up to 80% lower than the cost of the brand-name drug. This is because generic drugs are usually much cheaper to produce than brand-name drugs, and the competition among different generic manufacturers can drive the prices down even further.

Moreover, some pharmacies and drug manufacturers offer discounts and coupons for generic Lipitor to make it even more affordable. NPR [3] reported that some pharmacies offer generic Lipitor for as low as $4 for a 30-day supply, while some drug manufacturers offer the drug for free to eligible patients.

In conclusion, the cost of generic Lipitor can vary depending on the pharmacy and the location, but it is generally much cheaper than the brand-name drug. The cost of generic Lipitor can be up to 80% lower than the cost of the brand-name drug. Additionally, some pharmacies and drug manufacturers offer discounts and coupons for generic Lipitor to make it even more affordable.
