Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. According to drugpatentwatch.com [1], the patent for Lipitor expired in 2011, which allowed other companies to start producing generic versions of atorvastatin. This has resulted in a significant decrease in the cost of atorvastatin compared to Lipitor.

Goodrx.com [2] reports that the average retail price of Lipitor is around $450 for a 30-day supply, while the average retail price of atorvastatin is around $10 for a 30-day supply. This is a significant cost difference, with atorvastatin being much more affordable than Lipitor.

The British Heart Foundation [3] also confirms that there are several alternatives to Lipitor and other statins, such as plant sterols, which are found in certain foods and supplements, and ezetimibe, which works by reducing the amount of cholesterol absorbed by the body. These alternatives may be more suitable for some people who are unable to take statins due to side effects or other health concerns.

In conclusion, the cost difference between Lipitor and alternatives such as atorvastatin is significant, with atorvastatin being much more affordable. However, it is important to consult with a healthcare professional to determine the most appropriate cholesterol-lowering medication or alternative based on individual health needs and circumstances.
