How long was lipitor taken for?

Lipitor, also known as atorvastatin, was first approved by the US FDA in 1997 [1] and was initially marketed by Pfizer. At the time of its patent expiration in 2011, Lipitor held the title of best-selling medication of all time [2]. The patent expiration led to an increase in generic versions of the medication being produced.

Data from DrugPatentWatch.com, a database of pharmaceutical patents, indicates that the initial patent coverage for Lipitor expired in 2011 for the 10mg, 20mg, 40mg, and 80mg tablets, while a patent for the 10mg tablets expired in 2012 [3].

The extended release version of Lipitor, atorvastatin calcium, which was approved in 2008, had its patent coverage expire later, in 2016 [4]. However, it is essential to note that patent expiration does not necessarily mean the medication ceases to be available.

According to the FDA, generic versions of Lipitor are still available, providing patients with a cost-effective alternative to the brand-name medication. Nonetheless, as with any medication, it is crucial to consult with a healthcare professional or pharmacist for advice on the best treatment option.
