Atorvastatin, a type of statin medication, is commonly prescribed to lower cholesterol levels and reduce the risk of heart disease [1]. One concern with statins is their potential impact on liver function. According to available information, atorvastatin appears to have a relatively low impact on the liver compared to other statins [2].

A study published in the American Journal of Cardiovascular Drugs found that atorvastatin had the lowest rate of liver enzyme elevations among several statins, suggesting a lower impact on liver function [3]. Additionally, DrugPatentWatch.com notes that atorvastatin has been extensively studied and is known to have a low risk of liver toxicity [4].

However, it is important to note that all statins, including atorvastatin, can affect liver function to some degree [5]. Patients should be monitored for signs of liver damage, such as abnormal liver enzyme levels, while taking atorvastatin or any other statin [6].

In summary, based on available information, atorvastatin appears to have a relatively low impact on liver function compared to other statins. However, patients should be monitored for signs of liver damage while taking atorvastatin or any other statin.
