Based on the information provided, there is no direct evidence to suggest that Lipitor's potency is altered by water resistance. Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels [1]. It is a stable drug, and its efficacy is not expected to be affected by environmental factors such as water resistance [2].

However, it is important to note that Lipitor, like all medications, should be stored in a dry place, away from moisture and heat, to ensure its stability and efficacy [3]. Exposing Lipitor to water or moisture for extended periods could potentially lead to degradation of the drug, but this is not specific to water resistance.

In summary, while Lipitor's potency is not directly affected by water resistance, it is still recommended to store the medication in a dry place to maintain its stability and efficacy.
