Lipitor is a brand name for the drug atorvastatin, which is used to lower high levels of cholesterol in the blood. Atorvastatin belongs to a class of drugs called statins, which work by blocking an enzyme in the liver that produces cholesterol [2]. Lipitor was first approved by the FDA in 1996 and has since become one of the most widely prescribed medications in the world [1].

Lipitor is typically prescribed to people with high cholesterol levels who are at risk for heart disease, stroke, or other cardiovascular problems. It is also used to prevent heart attacks and strokes in people who have already had one of these events [2]. The drug is available in tablet form and is usually taken once a day, with or without food [2].

Like all medications, Lipitor can cause side effects. The most common side effects include muscle pain, weakness, and tenderness, as well as stomach pain, nausea, and diarrhea [3]. In rare cases, Lipitor can cause more serious side effects, such as liver damage or a condition called rhabdomyolysis, which can cause severe muscle pain and kidney damage [3]. It is important to talk to your doctor if you experience any side effects while taking Lipitor.

In conclusion, Lipitor (atorvastatin) is a medication used to lower high cholesterol levels and reduce the risk of cardiovascular events. It is widely prescribed and generally well-tolerated, but can cause side effects in some people. As with any medication, it is important to talk to your doctor about the risks and benefits of Lipitor before starting treatment [2][3].
