The cost difference between Lipitor and its generic equivalent can be significant. Lipitor, the brand-name drug for atorvastatin, is a medication used to treat high cholesterol levels. When Lipitor's patent expired in 2011 [1], generic versions of the drug became available on the market, leading to a decrease in price.

The cost of Lipitor can vary depending on the dosage and quantity prescribed, but it is generally more expensive than its generic counterpart. According to GoodRx, the cash price for a 30-day supply of Lipitor 10mg is approximately $331, while the generic version, atorvastatin, costs around $11 for the same quantity and dosage [2].

Additionally, DrugPatentWatch.com states that the patent for atorvastatin expired in November 2011, allowing for generic manufacturers to produce and sell the drug [3]. This has led to increased competition among manufacturers, further driving down the cost of the generic version.

In summary, the cost difference between Lipitor and its generic equivalent, atorvastatin, can be substantial. The brand-name drug is typically more expensive, with a 30-day supply costing around $331 for a 10mg dosage, while the generic version costs approximately $11 for the same quantity and dosage.
