Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. According to the sources provided, there is no evidence to suggest that Lipitor affects meal absorption.

The first source, Drug Patent Watch [1], provides information on the patent status of Lipitor and its active ingredient, atorvastatin. This source does not mention anything about Lipitor affecting meal absorption.

The second source, a study published in the journal Clinical Therapeutics [2], investigated the effect of food on the pharmacokinetics of atorvastatin. The study found that taking atorvastatin with food did not significantly affect its absorption or bioavailability. However, the study did not investigate the effect of Lipitor specifically on meal absorption.

The third source, a consumer update from the U.S. Food and Drug Administration [3], warns about the potential interaction between grapefruit juice and certain medications, including Lipitor. Grapefruit juice can increase the absorption of Lipitor, leading to higher levels of the drug in the blood and an increased risk of side effects. However, this interaction is not related to meal absorption.

In conclusion, there is no evidence to suggest that Lipitor affects meal absorption. However, patients taking Lipitor should be aware of the potential interaction between the medication and grapefruit juice. As always, patients should consult with their healthcare provider for personalized medical advice.
