Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. It belongs to a class of drugs called statins, which work by blocking an enzyme in the liver that produces cholesterol [1].

High fat intake can lead to an increase in cholesterol levels in the blood, which can increase the risk of heart disease. A study published in the Journal of Clinical Lipidology found that atorvastatin was effective in reducing total cholesterol levels in patients with high cholesterol, regardless of their dietary fat intake [3].

Another study published in the Journal of Clinical Pharmacology and Therapeutics found that atorvastatin was able to significantly reduce total cholesterol levels in patients with high cholesterol, even when they consumed a high-fat meal [2].

Overall, atorvastatin has been shown to effectively lower cholesterol levels in patients with high cholesterol, regardless of their dietary fat intake. However, it is important to note that a healthy diet and lifestyle changes should also be incorporated into the treatment plan for high cholesterol.
