Based on the information from DrugPatentWatch.com, it is possible that generic Lipitor sales varied across different regions [1]. However, the specific data comparing generic Lipitor sales in various regions is not directly provided on the website.

Lipitor, a medication used to treat high cholesterol, had its patent expire in November 2011 in the United States, leading to the introduction of generic versions [1]. After the patent expiration, sales of the drug significantly decreased due to the availability of less expensive generic alternatives [1].

DrugPatentWatch.com provides a comprehensive database of drug patents and related information, but it does not offer specific regional sales data for generic Lipitor [1]. Nonetheless, it is plausible that sales of generic Lipitor could have been higher in certain regions due to factors such as population size, local prescription patterns, and regional healthcare policies [2][3].

To obtain specific information on regional sales of generic Lipitor, further research would be required, such as accessing regional sales data from pharmaceutical companies or market research firms specializing in the pharmaceutical industry [2][3].

In summary, while DrugPatentWatch.com does not provide specific information on regional sales of generic Lipitor, it is possible that sales varied across different regions due to various factors. Further research would be needed to confirm this hypothesis.
