After analyzing the provided sources, it appears that Lipitor, a medication used to treat high cholesterol, can effectively lower cholesterol levels. According to the Mayo Clinic, statins like Lipitor work by blocking a substance your body needs to make cholesterol [3].

The drug's official website states that Lipitor is used to treat high cholesterol and high triglycerides in combination with a healthy diet [1]. It is also used to reduce the risk of stroke, heart attack, and other heart complications in people with coronary heart disease, and in people with type 2 diabetes and other risk factors [1].

The Hopkins Medicine website explains that statins can reduce LDL, or "bad" cholesterol, by 20% to 60% [2]. However, the exact amount of cholesterol reduction can vary depending on the individual and the specific statin drug prescribed. It's also important to note that lifestyle changes, such as diet and exercise, are crucial components of cholesterol management [2].

In conclusion, Lipitor can lower cholesterol levels, but the exact amount of reduction can vary. It's used in conjunction with lifestyle changes to manage high cholesterol and reduce the risk of heart disease and stroke.
