See the DrugPatentWatch profile for lipitor

Lipitor, a medication commonly prescribed to lower cholesterol levels, contains the active ingredient atorvastatin [1]. It works by inhibiting the HMG-CoA reductase, an enzyme that plays a crucial role in the production of cholesterol in the body [1][2].

By inhibiting this enzyme, Lipitor reduces the amount of low-density lipoprotein (LDL), or "bad" cholesterol, in the blood [1][2]. High levels of LDL cholesterol can lead to the formation of plaque in the arteries, increasing the risk of heart disease and stroke [1][2].

In addition to lowering LDL cholesterol, Lipitor also increases the levels of high-density lipoprotein (HDL), or "good" cholesterol, which helps remove LDL cholesterol from the bloodstream [1][2].

Furthermore, Lipitor has been shown to reduce the risk of heart attack, stroke, and the need for procedures to open blocked arteries in people who have heart disease or risk factors for heart disease [1][2].

It is important to note that Lipitor is just one component of a comprehensive approach to managing cholesterol levels and promoting heart health [1][2]. A heart-healthy lifestyle, including a balanced diet, regular exercise, and avoiding tobacco and excessive alcohol use, is also crucial [1][2].
