Lipitor is a medication used to lower cholesterol levels in the body [3]. According to Drug Patent Watch [1], the active ingredient in Lipitor is atorvastatin calcium. The medication works by blocking an enzyme that the body uses to make cholesterol, which can help reduce the risk of heart disease and stroke [3].

While there is no direct evidence to suggest that Lipitor can affect the taste of red wine, it is important to note that consuming alcohol while taking Lipitor can have negative effects on the liver and increase the risk of liver damage [2]. Health Harvard explains that when the liver processes alcohol and statins like Lipitor at the same time, it can lead to liver damage [2]. Therefore, it is recommended to avoid consuming large amounts of alcohol while taking Lipitor.

In summary, Lipitor is a medication used to lower cholesterol levels in the body, and the active ingredient in Lipitor is atorvastatin calcium [1][3]. While there is no direct evidence to suggest that Lipitor can affect the taste of red wine, it is important to note that consuming alcohol while taking Lipitor can have negative effects on the liver and increase the risk of liver damage [2].
