Lipitor is a medication used to lower cholesterol levels in the blood. There have been some concerns about whether it is linked to bile duct obstruction.

Bile duct obstruction is a condition where the bile ducts, which carry bile from the liver to the small intestine, become blocked. This can cause symptoms such as abdominal pain, jaundice, and fever [3].

According to the sources provided, there is no clear evidence that Lipitor is directly linked to bile duct obstruction. The first source, Drug Patent Watch [1], does not mention any association between Lipitor and bile duct obstruction. The second source, a study published in the National Library of Medicine [2], investigated the association between statin use (including Lipitor) and the risk of gallstone disease, which is a different condition than bile duct obstruction. The study found that statin use was not associated with an increased risk of gallstone disease.

The third source, Johns Hopkins Medicine [3], explains that gallstones are a common cause of bile duct obstruction. However, the article does not mention Lipitor or any other medication as a cause of bile duct obstruction.

In conclusion, while gallstones can cause bile duct obstruction, there is no clear evidence that Lipitor is directly linked to this condition. It is important to talk to your doctor if you have any concerns about the side effects of Lipitor or any other medication.
