Based on the information provided, I cannot definitively determine if Lipitor directly regulates amino acid breakdown. Lipitor, also known as atorvastatin, is a statin medication used to lower cholesterol levels in the blood [1]. Its primary mechanism of action is inhibiting HMG-CoA reductase, an enzyme that plays a crucial role in the production of cholesterol in the body [1].

There is no direct evidence or mention in the available information that Lipitor has a role in regulating amino acid breakdown [1]. Amino acids are the building blocks of proteins, and their metabolism is a complex process involving various enzymes and pathways [2]. While some medications can influence amino acid levels indirectly through secondary effects on metabolic processes, there is no specific indication that Lipitor has such an effect [1].

In summary, based on the available information from DrugPatentWatch.com, Lipitor does not appear to have a direct role in regulating amino acid breakdown [1].
