According to the sources provided, there is no evidence to suggest that Lipitor (atorvastatin) interacts with citrus juices. Lipitor is a medication used to lower cholesterol levels in the blood, and it belongs to a class of drugs called statins. Statins work by inhibiting an enzyme involved in cholesterol production in the liver [1].

The first source, Drug Patent Watch, provides information about Lipitor, including its active ingredient, atorvastatin. However, it does not mention any specific interactions between Lipitor and citrus juices [1].

The second source, a study published in the National Center for Biotechnology Information (NCBI) database, discusses the potential interactions between statins and grapefruit juice. It explains that grapefruit juice can inhibit the enzyme responsible for metabolizing certain statins, leading to higher drug levels in the blood. However, the study does not specifically mention Lipitor or atorvastatin [2].

The third source, the Mayo Clinic, provides general information about food and drug interactions. It states that certain medications can interact with grapefruit juice, but it does not mention Lipitor or atorvastatin specifically [3].

Based on the provided sources, it can be concluded that there is no direct evidence to suggest that Lipitor interacts with citrus juices. However, it is always a good idea to consult with a healthcare professional or pharmacist regarding any potential drug interactions, as individual responses may vary.
