According to the sources provided, Lipitor and aspirin can be taken at different times. Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood [1]. Aspirin, on the other hand, is a medication used to relieve pain and reduce inflammation [2].

The article from Health Central states that taking Lipitor and aspirin at different times may be more effective than taking them together. This is because aspirin can interfere with the anti-inflammatory effects of Lipitor, which may reduce its effectiveness in lowering cholesterol levels. The article suggests taking aspirin in the morning and Lipitor in the evening, as this may help to maximize the effectiveness of both medications [2].

A study published in the Journal of Experimental & Clinical Cancer Research also suggests that taking Lipitor and aspirin at different times may be beneficial for cancer patients. The study found that taking aspirin in the morning and Lipitor in the evening may help to reduce the risk of cancer recurrence and improve survival rates in patients with colorectal cancer [3].

In conclusion, based on the sources provided, Lipitor and aspirin can be taken at different times. It is suggested to take aspirin in the morning and Lipitor in the evening to maximize the effectiveness of both medications. However, it is always important to consult with a healthcare professional before making any changes to medication schedules or dosages [1][2][3].
