See the DrugPatentWatch profile for lipitor

Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels. It belongs to a class of drugs called statins, which work by blocking the production of cholesterol in the body. According to DrugPatentWatch.com, Lipitor is one of the most prescribed medications in the United States [1].

When it comes to the interaction between Lipitor and protein-rich meals, there is limited information available. However, it is generally recommended that Lipitor be taken at the same time each day, with or without food [2]. A study published in the Journal of Clinical Pharmacology found that the absorption of atorvastatin was not significantly affected by food, including high-fat meals [3].

However, it is important to note that certain foods can interfere with the effectiveness of Lipitor. Grapefruit and grapefruit juice, for example, can increase the amount of Lipitor in the blood, which can increase the risk of side effects [4]. Therefore, it is generally recommended to avoid consuming grapefruit or grapefruit juice while taking Lipitor.

In summary, based on the available information, Lipitor can be taken with or without food, and the absorption of the medication is not significantly affected by food. However, it is important to avoid consuming grapefruit or grapefruit juice while taking Lipitor, as it can increase the amount of the medication in the blood and increase the risk of side effects.
