Lipitor is a brand name for the medication atorvastatin, which is a type of medication called a statin that is used to lower cholesterol levels in the blood. According to the drug patent watch website [1], the patent for Lipitor expired in 2011, meaning that generic versions of atorvastatin are now available. This could potentially make it more affordable for patients who need this medication.

However, if a patient is unable to take atorvastatin or Lipitor due to side effects or other reasons, there are other statins available that may be able to replace it. According to MedlinePlus [2], some other commonly used statins include simvastatin, pravastatin, and rosuvastatin. These medications work in a similar way to atorvastatin to lower cholesterol levels.

In addition to statins, there are other medications and lifestyle changes that can also help to lower cholesterol levels. According to a WebMD article [3], some of these options include bile acid sequestrants, niacin, and fibrates. However, it is important to discuss any potential changes to medication or lifestyle with a healthcare provider to determine the best course of action.
