Lipitor is a brand name for the drug atorvastatin, which belongs to a class of drugs called statins. Statins are commonly prescribed to lower cholesterol levels and reduce the risk of heart disease. While the sources provided do not mention stretching frequency specifically, they do provide information on the effects of Lipitor.

According to Drug Patent Watch [1], Lipitor is indicated for the treatment of high cholesterol, specifically hyperlipidemia and mixed dyslipidemia. It works by inhibiting an enzyme in the liver that is responsible for producing cholesterol, which results in a decrease in the amount of cholesterol in the blood.

The British Heart Foundation [2] notes that statins like Lipitor have been shown to reduce the risk of heart attacks and strokes in people with high cholesterol. They also mention that statins may have other benefits, such as reducing inflammation and improving the function of blood vessels.

A review of the literature on statins by the National Center for Biotechnology Information [3] found that statins can reduce the risk of cardiovascular events, including heart attacks and strokes, in people with or without a history of cardiovascular disease. They also found that statins may have other beneficial effects, such as reducing the risk of certain cancers and improving bone health.

In summary, while the sources provided do not mention stretching frequency specifically, they do suggest that Lipitor can be effective in reducing cholesterol levels and lowering the risk of cardiovascular events. It is important to note that any changes in medication should be discussed with a healthcare provider.
