Lipitor is a medication used to lower cholesterol levels in the blood. The drug is produced by Pfizer and has been available in the United States since 1996. According to the Drug Patent Watch website [1], the patent for Lipitor expired in 2011, which means that generic versions of the drug are now available.

One way to obtain discounts on Lipitor is through the use of coupons or discount cards. GoodRx [2] provides information on Medicare coverage for Lipitor and offers discounts for those who are uninsured or underinsured. However, it is important to note that there may be restrictions on the use of these discounts.

In 2010, Senators Baucus, Grassley, and Kohl conducted an investigation into pharmaceutical deals that limit access to generic drugs [3]. The investigation found that some drug companies were using anti-competitive tactics to delay the entry of generic drugs into the market. This could potentially limit the availability of discounts on Lipitor and other medications.

In conclusion, while there are discounts available for Lipitor through coupons and discount cards, there may be restrictions on their use. It is important to be aware of any potential limitations and to consult with a healthcare provider or pharmacist before using these discounts.
