Lipitor, a medication commonly used to treat high cholesterol, does not directly contribute to pain relief in any products. Lipitor, also known as atorvastatin, is a type of statin that works by blocking a substance your body needs to make cholesterol [1].

It is important to note that Lipitor is not marketed or indicated for pain relief. The drug's primary mechanism of action is to lower the levels of low-density lipoprotein (LDL) or "bad" cholesterol and triglycerides in the blood, thereby reducing the risk of heart attack and stroke [1].

The confusion might arise from the fact that cholesterol-lowering medications like Lipitor are sometimes prescribed to patients with certain conditions that can cause pain, such as peripheral artery disease (PAD) [2]. In these cases, Lipitor is used to manage the cholesterol levels of the patients, which can help alleviate symptoms of PAD and other conditions indirectly. However, the pain relief in these instances is not a direct result of taking Lipitor but rather a secondary benefit of managing the underlying condition.

In summary, Lipitor does not directly contribute to pain relief in any products. Its primary function is to lower cholesterol levels, which can have indirect effects on symptoms of certain conditions.
