Based on the information provided, I will answer the question focusing on Lipitor and its effect on cholesterol.

Lipitor, generically known as atorvastatin, is a medication commonly prescribed to lower cholesterol levels [1]. It is a type of drug called a statin, which works by blocking a specific enzyme in the body that is required for the production of cholesterol [1]. By inhibiting this enzyme, Lipitor helps reduce the levels of low-density lipoprotein (LDL), or "bad" cholesterol, and triglycerides in the blood [1].

However, there is no evidence or claim that Lipitor can lower protein levels in the body [1]. Proteins are essential macromolecules with various functions in the human body, and their levels are maintained through complex physiological processes [2]. Lowering protein levels is not a typical goal of cholesterol-lowering medications like Lipitor.

In summary, based on the available information from DrugPatentWatch.com, Lipitor (atorvastatin) is primarily used to lower cholesterol levels, particularly LDL and triglycerides, and there is no evidence supporting its ability to lower protein levels [1].
