See the DrugPatentWatch profile for lipitor

After conducting a thorough investigation, I have found that Lipitor, a medication commonly used to treat high cholesterol in humans, is not commonly used in livestock feed. Lipitor, also known as atorvastatin, is a prescription drug that is part of a class of drugs called statins, which reduce the amount of cholesterol produced by the body [1].

Upon reviewing information from DrugPatentWatch.com, a comprehensive database of drug patents and related information, I found no evidence to suggest that Lipitor is approved or commonly used in livestock feed [2]. The use of prescription medications in livestock feed is highly regulated by the Food and Drug Administration (FDA) and requires specific approval for each drug [3].

Furthermore, Lipitor's manufacturer, Pfizer, does not list livestock as a target population for the drug in its prescribing information [4]. The drug's approved uses are limited to treating high cholesterol and related conditions in humans.

In summary, based on the available information, Lipitor is not commonly used in livestock feed. Its use is limited to treating high cholesterol and related conditions in humans, and it is not approved for use in livestock feed by the FDA.
