Lipitor, a medication used to treat high cholesterol, has been subject to patent expirations which have influenced the entry of generic competitors into the market. According to DrugPatentWatch.com [1], Lipitor's patent expired in November 2011 in the United States, allowing generic manufacturers to produce and sell generic versions of the drug.

The pricing of Lipitor has played a significant role in shaping the competitive landscape of the generic market. Before the patent expiration, Lipitor was a blockbuster drug, generating billions in revenue for its manufacturer, Pfizer [2]. The high price of Lipitor created a lucrative opportunity for generic manufacturers to enter the market and capture a share of the revenue.

Once generic versions of Lipitor became available, they were priced significantly lower than the brand-name drug [3]. This price difference created an incentive for consumers and insurers to switch from Lipitor to the less expensive generic alternatives. As a result, generic manufacturers were able to rapidly gain market share, and Lipitor's sales declined sharply [4].

The entry of generic competitors and the subsequent price competition have led to significant cost savings for consumers and the healthcare system as a whole. According to the Federal Trade Commission, the availability of generic drugs saves consumers and the healthcare system an estimated $3 billion per week [5].

In summary, Lipitor's pricing has had a significant impact on generic competition. The high price of Lipitor before patent expiration created a lucrative opportunity for generic manufacturers, leading to rapid entry and price competition once generic versions became available. This competition has resulted in significant cost savings for consumers and the healthcare system.
