There is no clear information available from the provided sources that directly addresses whether Lipitor is vegan-friendly. Lipitor is a medication used to treat high cholesterol and triglycerides, and it contains atorvastatin calcium as the active ingredient [1]. Atorvastatin calcium is a synthetic compound that is not derived from animal sources, which may suggest that Lipitor is vegan-friendly [2]. However, it is important to note that the manufacturing process of Lipitor may involve the use of animal-derived ingredients or testing, which could make it unsuitable for vegans [2].

It is recommended that individuals consult with their healthcare provider or the manufacturer of Lipitor to obtain more information about the vegan-friendliness of the medication. Additionally, individuals may consider seeking out vegan-friendly alternatives to Lipitor, such as plant-based statins, to treat high cholesterol and triglycerides [2].
