Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. According to the sources provided, it is unclear if a new dosage of Lipitor has been released. However, the sources do provide information on the effectiveness of different dosages of Lipitor.

The first source [1] provides information on the patent status of Lipitor, indicating that the drug has been off-patent since 2011. This means that multiple manufacturers can produce the medication, and it is possible that different dosages may be available from different manufacturers.

The second source [2] provides dosing information for Lipitor. The recommended starting dose for most adults is 10-20 mg once daily, with a maximum dose of 80 mg once daily. The appropriate dosage may vary depending on individual factors such as age, gender, and other medical conditions. It is important to follow the dosing instructions provided by a healthcare provider.

The third source [3] is a study that compares the effectiveness of different dosages of atorvastatin in reducing cholesterol levels. The study found that higher dosages of atorvastatin were more effective in reducing LDL cholesterol levels than lower dosages. However, higher dosages were also associated with a higher risk of side effects.

In conclusion, while it is unclear if a new dosage of Lipitor has been released, the sources provided suggest that different dosages of atorvastatin may be available from different manufacturers. The recommended starting dose for most adults is 10-20 mg once daily, with a maximum dose of 80 mg once daily. Higher dosages may be more effective in reducing cholesterol levels, but may also increase the risk of side effects. It is important to follow the dosing instructions provided by a healthcare provider.
