Lipitor is a brand name for the drug atorvastatin, which is a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], Lipitor was first approved by the US Food and Drug Administration (FDA) in 1996 and is now available as a generic medication.

Smoking is a well-known risk factor for cardiovascular disease, and quitting smoking has been shown to reduce the risk of heart disease. A study published in the journal Circulation Research [2] found that smoking cessation can lead to improved vascular function and reduced inflammation in the body, which can help to prevent heart disease.

While there is no direct link between Lipitor and quitting smoking, a study published in the journal Clinical Pharmacology and Therapeutics [3] found that atorvastatin can improve endothelial function in smokers. Endothelial function refers to the ability of the cells lining the blood vessels to dilate and contract in response to changes in blood flow. Improving endothelial function can help to reduce the risk of cardiovascular disease.

In conclusion, while there is no direct link between Lipitor and quitting smoking, quitting smoking can help to reduce the risk of heart disease, and atorvastatin (the active ingredient in Lipitor) has been shown to improve endothelial function in smokers. It is important to consult with a healthcare professional before making any changes to medication or lifestyle habits.
