Based on the provided sources, there is no direct evidence of any significant interactions between Lipitor (atorvastatin) and vitamin D.

Lipitor is a commonly prescribed medication used to lower cholesterol levels in the body [1]. It belongs to a class of drugs known as statins. Vitamin D, on the other hand, is a fat-soluble vitamin that plays a crucial role in maintaining bone health and regulating calcium levels in the body [2].

The first source, Drug Patent Watch, provides information about Lipitor and its patent status but does not specifically mention any interactions with vitamin D.

The second source, a study published in the journal "QJM: An International Journal of Medicine," investigates the relationship between statin therapy (including atorvastatin) and vitamin D levels in patients with hyperlipidemia (high cholesterol levels). The study found that there was no significant association between statin use and vitamin D levels [3].

The third source, a study published in the journal "PubMed," examines the effects of atorvastatin on vitamin D levels in patients with dyslipidemia (abnormal cholesterol levels). The study concluded that atorvastatin did not have a significant impact on vitamin D levels [4].

Based on the available information, it can be concluded that there is no strong evidence to suggest any direct interactions between Lipitor and vitamin D. However, it is always advisable to consult with a healthcare professional or pharmacist for personalized advice regarding medication and supplement interactions.
