Aspirin and Lipitor are commonly used medications, and it is important to know how to take them safely. According to HealthCentral [2], taking aspirin and Lipitor together is generally safe. However, it is recommended to wait at least two hours after taking Lipitor before taking aspirin. This is because Lipitor is a statin medication that works to lower cholesterol levels in the blood, while aspirin is a blood thinner that helps to prevent blood clots. Taking aspirin too soon after Lipitor can increase the risk of bleeding.

It is important to note that the timing of taking aspirin and Lipitor may vary depending on individual health conditions and other medications being taken. Therefore, it is always recommended to consult with a healthcare provider before taking any new medications or changing the timing of medication intake.

Drug Patent Watch [1] provides information on the patent status of aspirin. The patent for aspirin has expired, meaning that generic versions of the medication are available. This can make the medication more affordable and accessible for individuals who need it.

Finally, a study published in the Journal of Experimental & Clinical Cancer Research [3] suggests that aspirin may have potential as an adjuvant therapy for cancer treatment. The study found that aspirin can enhance the effectiveness of chemotherapy drugs in treating cancer cells. However, further research is needed to fully understand the potential benefits and risks of using aspirin as a cancer treatment.
