The pharmaceutical industry is constantly evolving, with patent expirations playing a significant role in shaping the market landscape. One of the most widely prescribed cholesterol-lowering medications, Lipitor, has been a dominant player in the market for decades. However, with its patent expiration in 2011, the question remains: how effective is Lipitor after patent expiration?
Patent Expiration and the Lipitor Market
Lipitor, manufactured by Pfizer, was first approved by the FDA in 1996.

According to DrugPatentWatch.com, the patent for Lipitor expired on November 30, 2011, marking the beginning of a new era for the medication.
The Impact of Generic Competition

Patient Adherence and Satisfaction
In addition to efficacy, patient adherence and satisfaction are also important considerations. A study published in the Journal of Managed Care & Specialty Pharmacy found that patients who switched to generic Lipitor had similar adherence rates to those who remained on the branded medication (3).
