Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. According to DrugPatentWatch [1], the patent for Lipitor expired in 2011, which means that generic versions of atorvastatin are available. GoodRx [2] lists several alternatives to Lipitor, including other statins such as simvastatin, rosuvastatin, and pravastatin. Additionally, GoodRx notes that there are non-statin options available, such as ezetimibe and bile acid sequestrants. Drugs.com [3] offers a comparison tool for Lipitor and its generic alternatives, which can help patients and healthcare providers make informed decisions about which medication is best for their needs. It is important to note that while generic versions of atorvastatin are available, patients should always consult with their healthcare provider before making any changes to their medication regimen.
