Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the body. According to DrugPatentWatch [1], Lipitor is classified as an HMG-CoA reductase inhibitor, which works by blocking an enzyme that produces cholesterol in the liver. As for the interaction of Lipitor with cheese, StatNews [2] states that there is no direct interaction between the two. However, the article mentions that consuming grapefruit or grapefruit juice while taking Lipitor can increase the risk of side effects, as grapefruit can inhibit the breakdown of the drug in the body. Therefore, it is recommended to avoid consuming grapefruit or grapefruit juice while taking Lipitor.

The article from US Pharmacist [3] provides additional information on food-drug interactions. It states that certain foods can affect the absorption, metabolism, and excretion of drugs, which can lead to changes in their effectiveness or side effects. However, there is no mention of any specific interaction between Lipitor and cheese in this article.

In summary, there is no direct interaction between Lipitor and cheese. However, it is recommended to avoid consuming grapefruit or grapefruit juice while taking Lipitor due to the potential for increased side effects.
