Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], Lipitor's patent expired in 2011, which means that other companies can now produce and sell generic versions of atorvastatin.

A study published in the Journal of the American Heart Association [3] found that plant-based protein sources, such as beans, lentils, and peas, can lower cholesterol levels and reduce the risk of heart disease. The study compared the effects of plant-based proteins to animal-based proteins, such as meat and dairy, and found that plant-based proteins were more effective in reducing LDL cholesterol levels.

Another study published in the National Center for Biotechnology Information [2] found that consuming soy protein, which is a plant-based protein source, can also lower cholesterol levels in the blood. The study concluded that consuming soy protein can be an effective dietary strategy for managing cholesterol levels in individuals with high cholesterol.

In conclusion, while Lipitor is a commonly prescribed medication for managing high cholesterol levels, consuming plant-based protein sources such as beans, lentils, peas, and soy protein can also be an effective dietary strategy for managing cholesterol levels and reducing the risk of heart disease.
