Based on the information available, Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the body. It belongs to a class of drugs called statins, which work by blocking the production of cholesterol in the body. While Lipitor is not primarily marketed for its liver-protecting features, it has been observed to have a liver-protecting effect as a side benefit [1].

In terms of drugs with similar liver-protecting features as Lipitor, there are a few options. However, it is essential to note that the primary purpose of these medications is not to protect the liver. Instead, they have other primary uses, and their liver-protecting effects are secondary.

One such drug is N-acetylcysteine (NAC), which is an antioxidant that helps to reduce liver damage caused by toxins and free radicals. NAC is primarily used to treat acetaminophen (Tylenol) overdose, but it has also been shown to have liver-protecting effects [2].

Another drug with liver-protecting features is ursodeoxycholic acid (UDCA), which is primarily used to treat gallstones and liver diseases such as primary biliary cholangitis. UDCA works by decreasing the concentration of harmful bile acids in the liver, which can help protect the liver from damage [3].

It is essential to consult with a healthcare provider before starting any new medication, including those with liver-protecting features. While these drugs may have liver-protecting effects, they also have potential side effects and interactions with other medications.

In summary, while Lipitor has liver-protecting features, it is not primarily marketed for this purpose. Other drugs with liver-protecting features include N-acetylcysteine and ursodeoxycholic acid. However, it is crucial to consult with a healthcare provider before starting any new medication.
