Lipitor, a medication commonly used to treat high cholesterol, has been shown to effectively lower cholesterol levels. According to DrugPatentWatch.com, Lipitor (atorvastatin) is a statin drug that works by blocking a substance your body needs to make cholesterol [1].

A study published in the American Journal of Cardiology found that, on average, total cholesterol levels decreased by approximately 35-45% in patients treated with Lipitor [2]. The exact decrease can vary depending on factors such as the individual's initial cholesterol level, the dosage of Lipitor prescribed, and lifestyle changes accompanying the medication use.

It is important to note that while Lipitor can significantly decrease cholesterol levels, it is most effective when used in combination with a heart-healthy diet and regular exercise [3]. Additionally, regular monitoring of cholesterol levels and potential side effects is necessary while taking Lipitor [1].

In summary, Lipitor typically decreases cholesterol levels by approximately 35-45%, but the exact decrease can vary. It is crucial to use this medication in conjunction with a heart-healthy lifestyle and regular medical monitoring.
