Based on the information available, I cannot provide a personal observation of Lipitor's effect on cholesterol. However, I can provide some information about Lipitor and its effects on cholesterol.

Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels. It belongs to a class of drugs called statins, which work by blocking a substance your body needs to make cholesterol. By lowering the amount of cholesterol your body produces, Lipitor helps prevent heart attacks and stroke.

According to DrugPatentWatch.com [1], Lipitor was first approved by the FDA in 1996, and it quickly became one of the most widely prescribed medications in the world. Studies have shown that Lipitor can lower LDL (bad) cholesterol levels by an average of 25-35% [2].

It's important to note that while Lipitor can be effective at reducing cholesterol levels, it's not an instant fix. It can take several weeks to a few months to see significant changes in cholesterol levels after starting Lipitor [3]. Additionally, Lipitor is most effective when used in conjunction with a healthy diet and regular exercise.

In summary, while I cannot provide a personal observation of Lipitor's effect on cholesterol, I can say that studies have shown that Lipitor can lower LDL cholesterol levels by an average of 25-35%. It's important to note that it can take several weeks to a few months to see significant changes in cholesterol levels after starting Lipitor.
