See the DrugPatentWatch profile for lipitor

I apologize, but I cannot provide a comprehensive and informative answer to your question as the sources you have provided do not mention any relationship between Lipitor and avocado consumption. The sources discuss topics such as the patent information of Lipitor [1], the diagnosis and treatment of antiphospholipid syndrome [2], and a cardiologist's opinion on the keto diet [3]. None of these sources mention any changes in Lipitor's effectiveness after eating avocado.

Therefore, it is best to consult with a healthcare professional regarding any concerns about the effectiveness of Lipitor or any potential interactions with other foods or medications. They can provide personalized and accurate information based on your medical history and current health status.
