Lipitor, a medication commonly used to treat high cholesterol, typically causes a significant reduction in low-density lipoprotein (LDL), also known as "bad" cholesterol. According to DrugPatentWatch.com, Lipitor is a statin, a class of drugs that work by blocking a substance your body needs to make cholesterol [1].

Clinical studies have shown that Lipitor can lower LDL cholesterol levels by approximately 25-60% depending on the dosage and the individual's response to the medication [2]. It is important to note that the reduction in LDL cholesterol levels can vary from person to person.

In addition, Lipitor has been shown to lower the risk of heart attack, stroke, and other heart complications in people with type 2 diabetes, coronary heart disease, or other risk factors for heart disease [3].

It is worth mentioning that, like all medications, Lipitor can have side effects and it is important for individuals to consult with their healthcare provider before starting this medication and to closely follow their recommended dosage and monitoring schedule.

In summary, Lipitor typically causes a reduction in LDL cholesterol levels by approximately 25-60%, depending on the individual's response to the medication. This reduction in LDL cholesterol levels can help lower the risk of heart attack, stroke, and other heart complications in people with type 2 diabetes, coronary heart disease, or other risk factors for heart disease.
