Lipitor is a brand name for the drug atorvastatin, which is a type of statin used to lower cholesterol levels in the blood [1]. Statins are a group of drugs that work by blocking the enzyme HMG-CoA reductase, which is responsible for producing cholesterol in the liver [2]. Eating pork while taking Lipitor does not pose any direct danger, but it is recommended to avoid high-fat foods, including pork, to help the drug work more effectively [3]. This is because high-fat foods can interfere with the absorption of atorvastatin, reducing its effectiveness in lowering cholesterol levels [3]. Therefore, it is advisable to follow a low-fat diet while taking Lipitor to achieve the best results [3].
