Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], atorvastatin is a member of the statin drug class and works by inhibiting an enzyme that the liver uses to produce cholesterol.

Hyperlipidemia is a medical condition characterized by high levels of lipids, or fats, in the blood. The Cleveland Clinic [2] states that hyperlipidemia can lead to atherosclerosis, which is the buildup of plaque in the arteries. Atherosclerosis can cause heart attacks, strokes, and other cardiovascular diseases.

A study published in the journal Circulation Research [3] investigated the effects of a high-fat diet on the efficacy of statin therapy in mice. The study found that a high-fat diet reduced the effectiveness of atorvastatin in reducing cholesterol levels in the blood. The study also found that a high-fat diet increased inflammation and oxidative stress in the arteries, which can contribute to the development of atherosclerosis.

Based on these sources, it is clear that a high-fat diet can reduce the effectiveness of atorvastatin in reducing cholesterol levels and may increase the risk of developing atherosclerosis. However, the sources do not provide specific information on whether there are any side effects when taking Lipitor with fatty meats. It is recommended to consult with a healthcare provider for personalized advice on medication and dietary interactions.
