Lipitor is a brand name for the medication atorvastatin, which is a type of statin used to lower cholesterol levels in the body. Statins work by blocking the enzyme in the liver that produces cholesterol, which can lead to a reduction in the amount of LDL or "bad" cholesterol in the blood [3].

According to DrugPatentWatch [1], Lipitor was first approved by the FDA in 1996 and has been widely prescribed since then. The medication has been shown to be effective in reducing LDL cholesterol levels by up to 60% in some patients [2]. However, the actual amount of cholesterol reduction can vary depending on factors such as the individual's starting cholesterol levels, their overall health, and other medications they may be taking [3].

It is important to note that while Lipitor can be effective in reducing cholesterol levels, it is not a cure for high cholesterol. Patients taking Lipitor or any other statin medication should also make lifestyle changes such as eating a healthy diet, exercising regularly, and quitting smoking in order to achieve the best results [2]. Additionally, patients taking Lipitor should be monitored regularly by their healthcare provider to ensure that the medication is working effectively and to watch for any potential side effects [3].

In conclusion, Lipitor (atorvastatin) can be effective in lowering cholesterol levels in the body, but the amount of reduction can vary depending on individual factors. Patients taking Lipitor should also make lifestyle changes and be monitored by their healthcare provider to achieve the best results.
