Lipitor (atorvastatin) and ACE inhibitors (angiotensin-converting enzyme inhibitors) are commonly prescribed medications for the treatment of high cholesterol and high blood pressure, respectively. While both drugs are generally well-tolerated, they can affect liver function in some patients.

According to DrugPatentWatch [1], Lipitor can cause liver damage in rare cases, although this side effect is uncommon. Patients taking Lipitor should have their liver function monitored regularly by a healthcare provider.

ACE inhibitors, on the other hand, are not typically associated with liver damage [2]. However, they can cause an increase in liver enzymes, which can be a sign of liver inflammation. This is usually a mild and reversible effect, but patients taking ACE inhibitors should also have their liver function monitored regularly [3].

It is important to note that the risk of liver damage or other side effects from these medications can vary depending on a patient's individual health status and other medications they may be taking. Patients should always consult with their healthcare provider before starting or stopping any medication, and should report any unusual symptoms or side effects.
