After conducting a thorough investigation, I have found no evidence to suggest that Lipitor is commonly used for addiction treatment. Lipitor, known generically as atorvastatin, is a medication used to treat high cholesterol and prevent heart disease [1]. It belongs to a class of drugs called statins, which work by reducing the amount of cholesterol produced by the body [1].

There is no mention of Lipitor being used for addiction treatment on the drug's official website, its manufacturer's website, or in any reputable medical sources [1][2]. Additionally, a search of DrugPatentWatch.com, a comprehensive database of drug patents and related information, does not yield any results indicating that Lipitor is used for addiction treatment [3].

It is important to note that while some medications used to treat addiction may have other therapeutic uses, there is no evidence to suggest that Lipitor is one of them. If you or someone you know is struggling with addiction, it is crucial to seek help from a qualified healthcare professional who can provide appropriate treatment options.

In summary, based on the available information, Lipitor is not commonly used for addiction treatment. It is a medication used to treat high cholesterol and prevent heart disease.
