Lipitor is a popular brand name for the drug atorvastatin, which is used to lower cholesterol levels in the body. According to Drug Patent Watch [1], Lipitor's patent expired in 2011, which means that other companies can now manufacture and sell generic versions of atorvastatin. GoodRx [2] suggests that generic atorvastatin is cheaper than Lipitor and is just as effective. Additionally, there are other types of cholesterol-lowering medications that can be used as alternatives to statins, such as bile acid sequestrants, niacin, and fibric acid derivatives, as noted by WebMD [3]. However, it is important to consult with a healthcare provider before switching to an alternative medication, as they can provide personalized recommendations based on individual health needs and medical history.
