Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood [1]. According to RxList, Lipitor works by blocking an enzyme in the liver that is responsible for producing cholesterol [2]. However, there is no evidence to suggest that Lipitor affects avocado digestion.

A study published in the Journal of Food Science and Technology examined the effect of avocado consumption on the absorption of atorvastatin [3]. The study found that consuming avocado with atorvastatin did not significantly affect the absorption of the medication. The researchers concluded that it is safe to consume avocado while taking atorvastatin.

In summary, there is no evidence to suggest that Lipitor affects avocado digestion. Additionally, a study found that consuming avocado with atorvastatin did not significantly affect the absorption of the medication [3].
