After reviewing the sources provided, there is no information to suggest that Lipitor (atorvastatin) affects avocado digestion. Lipitor is a medication used to lower cholesterol levels in the blood, and it works by inhibiting an enzyme involved in the production of cholesterol in the liver [2]. It is not known to have any direct effect on digestion, including the digestion of avocados.

The sources do not mention any interactions between Lipitor and avocados. However, it is important to note that grapefruit and grapefruit juice can interact with Lipitor and increase the risk of side effects [2]. This is because grapefruit contains compounds that can interfere with the metabolism of Lipitor in the body, leading to higher levels of the drug in the blood [3]. Therefore, it is recommended to avoid grapefruit and grapefruit juice while taking Lipitor.

In conclusion, there is no evidence to suggest that Lipitor affects avocado digestion. However, if you are taking Lipitor, it is important to be aware of potential interactions with grapefruit and grapefruit juice. As always, it is recommended to consult with a healthcare provider before making any changes to your medication or diet.
