According to the information provided, Lipitor (atorvastatin) is a medication used to treat high cholesterol levels. The exact amount of cholesterol decrease that can be expected with Lipitor can vary depending on several factors, such as the individual's initial cholesterol level, the dose of Lipitor prescribed, and other health conditions or medications.

In general, clinical studies have shown that Lipitor can lower LDL (or "bad") cholesterol levels by 30-60% [1]. However, it's important to note that these numbers are averages, and individual results may vary.

It's also worth mentioning that Lipitor is a prescription medication, and its use should be under the supervision of a healthcare professional. Regular monitoring of cholesterol levels and other health markers is important to ensure that the medication is working effectively and safely.

In addition, it's important to maintain a heart-healthy lifestyle while taking Lipitor, including a balanced diet, regular exercise, and avoiding tobacco and excessive alcohol use.
