Lipitor is a brand name for the drug atorvastatin, which is a medication used to lower cholesterol levels in the blood. The cost of Lipitor can vary significantly depending on several factors such as the dosage, the pharmacy, and the location. According to Drug Patent Watch [1], the patent for Lipitor expired in 2011, which led to the availability of generic versions of the drug, making it more affordable for patients. The cost difference between the brand name and generic versions of Lipitor can be significant, with the generic version being much cheaper. According to Drugs.com [2], the average retail price for a 30-day supply of Lipitor (20mg) is $406.39, while the generic version of atorvastatin (20mg) costs an average of $9.90 for the same amount. This price difference makes the generic version of atorvastatin a more cost-effective option for patients.

The chart also provides a comparison of the prices of different statins, including atorvastatin and Lipitor. According to the chart, the price of atorvastatin is significantly lower than that of Lipitor.

In conclusion, the cost difference between Lipitor and atorvastatin can be significant, with the generic version of atorvastatin being much cheaper. This price difference makes atorvastatin a more cost-effective option for patients. Both drugs are considered high-intensity statins and are effective at lowering cholesterol levels.
