According to the sources provided, there is no known interaction between Lipitor (atorvastatin) and salt substitutes. Lipitor is a medication used to lower cholesterol levels, while salt substitutes are typically used to reduce sodium intake.

However, it is important to note that Lipitor can interact with other medications and supplements. For example, it may interact with benazepril, a medication used to treat high blood pressure, and can increase the risk of side effects such as muscle pain and weakness [2]. Additionally, Lipitor can interact with certain vitamins and minerals, such as vitamin D and calcium, which can affect the absorption and effectiveness of the medication [3].

Therefore, it is important to always consult with a healthcare provider before taking any new medications or supplements, including salt substitutes, to ensure there are no potential interactions or adverse effects.
