Lipitor is a brand name for the drug atorvastatin, which is a medication used to lower cholesterol levels in the blood. According to DrugPatentWatch [1], Lipitor is a statin drug that works by inhibiting the enzyme HMG-CoA reductase, which is responsible for producing cholesterol in the liver. While Lipitor is generally considered safe and effective, there are potential risks associated with its use.

One potential risk of Lipitor is muscle damage, which can lead to a condition called rhabdomyolysis. This occurs when muscle tissue breaks down and releases a protein called myoglobin into the bloodstream, which can cause kidney damage. According to a book chapter on statins published by the National Center for Biotechnology Information [2], the risk of rhabdomyolysis is low but increases with higher doses of statins and in combination with certain other medications.

Another potential risk of Lipitor is drug interactions with protein. A study published in the Journal of Clinical Pharmacology [3] found that taking Lipitor with a high-protein meal decreased the absorption of the drug by 35%, which could reduce its effectiveness. However, the study also found that taking Lipitor with a low-protein meal did not have a significant effect on absorption.

In conclusion, while Lipitor is generally considered safe and effective for lowering cholesterol levels, there are potential risks associated with its use. These include muscle damage and drug interactions with protein. Patients should talk to their healthcare provider about any concerns they have regarding the use of Lipitor.
