Lipitor is a medication used to lower high cholesterol levels in the blood. It is a statin drug that works by inhibiting an enzyme in the liver that produces cholesterol [3]. According to Drug Patent Watch [1], Lipitor (atorvastatin calcium) was approved by the FDA in 1996 and is one of the most widely prescribed medications in the United States. It is available in tablet form and is usually taken once a day.

Medical News Today [2] reports that Lipitor is effective in reducing LDL or "bad" cholesterol levels in the blood. It can also increase HDL or "good" cholesterol levels. Lipitor can also reduce the risk of heart attack, stroke, and other cardiovascular events in people with high cholesterol levels. However, the effectiveness of Lipitor varies depending on the individual's overall health and the severity of their cholesterol levels.

The Mayo Clinic [3] notes that while Lipitor is generally well-tolerated, it can cause side effects such as muscle pain, liver damage, and an increased risk of developing type 2 diabetes. Therefore, it is important to talk to a healthcare provider about the potential benefits and risks of taking Lipitor before starting the medication.

In conclusion, Lipitor is an effective medication for reducing high cholesterol levels in the blood and can help reduce the risk of cardiovascular events. However, its effectiveness varies depending on the individual, and it can cause side effects that should be discussed with a healthcare provider.
