See the DrugPatentWatch profile for atorvastatin

Based on the information from DrugPatentWatch.com, it is reported that generic atorvastatin can be priced up to 90% lower than its brand-name counterpart, Lipitor [1]. This significant price difference is primarily due to the expiration of Lipitor's patent, allowing other manufacturers to produce and sell generic versions of the drug [1]. However, the exact percentage of the price reduction may vary depending on several factors, such as location, insurance coverage, and the specific manufacturer of the generic atorvastatin [1].

In conclusion, generic atorvastatin can be considerably cheaper than Lipitor, with potential savings of up to 90% [1].
