Based on the available information, there is no evidence to suggest that customized Lipitor doses for swimmers are common. Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol levels [1]. The drug patent watch website provided does not mention any specific dosage adjustments for swimmers or athletes [1].

Furthermore, a study published in the American Heart Association's journal Circulation found that there is limited evidence to support the use of statins, such as Lipitor, to enhance athletic performance [2]. The study notes that while some athletes may use statins to improve endurance, there is no clear evidence that these medications provide a significant benefit [2].

Additionally, the American Diabetes Association's position statement on physical activity and diabetes states that exercise can help lower blood glucose levels, but does not mention any specific medication dosage adjustments for athletes or swimmers [3].

In summary, based on the available information, there is no evidence to suggest that customized Lipitor doses for swimmers are common. While some athletes may use statins to improve endurance, there is limited evidence to support this practice. It is important for individuals taking Lipitor or any other medication to follow their healthcare provider's instructions and not make any changes to their dosage without medical supervision.
