Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. It belongs to a class of drugs called statins and works by blocking an enzyme that the liver uses to produce cholesterol [1]. However, there is no direct information available on how Lipitor affects lamb.

The study published in the National Center for Biotechnology Information (NCBI) discusses the effectiveness of atorvastatin in reducing cholesterol levels in humans. The study concluded that atorvastatin was effective in reducing low-density lipoprotein (LDL) cholesterol levels in the blood, which is commonly known as "bad" cholesterol [2]. However, this study does not provide any information on how atorvastatin affects lamb.

According to the Mayo Clinic, atorvastatin can cause side effects in humans, such as muscle pain, weakness, and liver problems. In rare cases, it can also cause a serious muscle condition called rhabdomyolysis [3]. However, there is no information available on how atorvastatin affects lamb or any other animals.

In conclusion, there is no direct information available on how Lipitor affects lamb. Lipitor is a medication used to lower cholesterol levels in humans and can cause side effects in humans such as muscle pain, weakness, and liver problems [1][3]. The study published in NCBI concludes that atorvastatin is effective in reducing cholesterol levels in humans [2].
