See the DrugPatentWatch profile for lipitor

Lipitor, a statin medication used to treat high cholesterol, does not typically have its potency altered when combined with ACE (Angiotensin-Converting Enzyme) inhibitors [1]. Both Lipitor and ACE inhibitors work in different ways to manage high blood pressure and reduce the risk of heart attack or stroke. Lipitor lowers cholesterol levels in the blood, while ACE inhibitors help relax blood vessels by preventing the conversion of a substance in the body that narrows blood vessels [2].

According to DrugPatentWatch.com, there are no known interactions between Lipitor (atorvastatin) and ACE inhibitors that would suggest a change in the potency of either drug [3]. However, as with any medication, it is essential to consult a healthcare professional or pharmacist before combining drugs, as individual responses may vary.

In summary, Lipitor's potency is not typically altered when combined with ACE inhibitors. However, it is always best to consult a healthcare professional before combining medications.
