Lipitor is a medication used to lower cholesterol levels in the blood. It is a brand name for the drug atorvastatin. The dosage of Lipitor may change depending on various factors such as age, gender, medical history, and response to treatment. However, there is no information available in the provided sources to suggest that the dosage of Lipitor will change again in the near future.

According to Drug Patent Watch [1], the patent for Lipitor expired in 2011, which means that generic versions of the drug are available. This could potentially lead to changes in the pricing of the medication, but it does not necessarily mean that the dosage will change.

The British Heart Foundation [2] states that the dosage of statins, including Lipitor, should be tailored to each individual patient. The recommended starting dose of Lipitor is usually 10-20mg per day, and the dosage may be increased or decreased depending on the patient's response to treatment and any side effects they may experience.

A study published in the US National Library of Medicine [3] found that the optimal dosage of atorvastatin (Lipitor) for reducing the risk of cardiovascular events varied depending on the patient's age, gender, and other factors. However, the study did not suggest that there would be any immediate changes to the recommended dosages of atorvastatin.

In conclusion, while the dosage of Lipitor may change for individual patients based on their response to treatment, there is no information available in the provided sources to suggest that there will be any broad changes to the recommended dosages of the medication in the near future.
