According to DrugPatentWatch.com, Lipitor (atorvastatin) is a medication used to treat high cholesterol levels, specifically lowering low-density lipoprotein (LDL), or "bad" cholesterol [1]. While the exact percentage of LDL reduction can vary depending on the individual's initial cholesterol levels, dosage, and other factors, clinical studies have shown that Lipitor can lower LDL cholesterol by approximately 25% to 60% [2][3]. However, it is essential to consult with a healthcare professional for personalized information regarding the potential efficacy of Lipitor.
