Why are withdrawal symptoms related to Lipitor?

When will Lipitor's patent expire, and what does this mean for patients?

Lipitor's patent expired in 2011, making generic versions of the medication available. However, the patent for atorvastatin calcium, a specific formulation of Lipitor, won't expire until 2036 [5]. This may limit the availability of generic versions of this formulation, but it's unlikely to have a significant impact on patients taking Lipitor.
