Lipitor, a popular cholesterol-lowering medication, has been a staple in the pharmaceutical industry for over two decades. Developed by Pfizer, Lipitor (atorvastatin) was first approved by the FDA in 1997 and quickly became one of the best-selling drugs of all time. With its effectiveness in reducing low-density lipoprotein (LDL) cholesterol levels, Lipitor has helped millions of people worldwide manage their cholesterol levels and reduce the risk of heart disease. But how long have Lipitor levels been stable?

History of Lipitor

Lipitor was first approved by the FDA in 1997 for the treatment of high cholesterol. Initially, it was marketed as a once-daily tablet, and its popularity soared due to its effectiveness and convenience. Over the years, Lipitor has undergone several changes, including the introduction of a generic version in 2011. Despite the introduction of generic alternatives, Lipitor remains a widely prescribed medication.
