According to the World Anti-Doping Agency (WADA), Lipitor, also known by its generic name atorvastatin, is classified as a prohibited substance in competitive sports [3]. Lipitor belongs to a class of drugs called statins, which are primarily used to lower cholesterol levels in individuals at risk of cardiovascular diseases [1]. The use of Lipitor is not allowed in sports competitions due to its potential performance-enhancing effects, such as improved endurance and muscle recovery [3].

As for alternatives to Lipitor that are allowed by WADA, it is important to note that WADA does not provide an exhaustive list of permitted medications. Instead, they maintain a list of prohibited substances and methods, which athletes are advised to consult to ensure compliance [3]. However, there are several other statins available on the market that can be used as alternatives to Lipitor, depending on an individual's specific medical condition and needs.

Some commonly prescribed statins that may be considered as alternatives to Lipitor include:

1. Crestor (rosuvastatin): Crestor is another widely used statin that helps lower cholesterol levels and reduce the risk of cardiovascular diseases. It is available in various doses and has been shown to be effective in managing cholesterol levels [2].

2. Zocor (simvastatin): Zocor is another statin medication that is commonly prescribed to lower cholesterol levels. It has been available for a longer time than Lipitor and has a proven track record of effectiveness [2].

3. Pravachol (pravastatin): Pravachol is a statin medication that is commonly prescribed to lower cholesterol levels. It is available in various doses and has been shown to be effective in managing cholesterol levels [2].

It is important to consult with a healthcare professional or a qualified medical practitioner to determine the most suitable alternative to Lipitor based on an individual's specific medical condition, medical history, and any other medications they may be taking. They will be able to provide personalized advice and guidance regarding the appropriate statin medication to use.

In conclusion, Lipitor is classified as a prohibited substance by WADA and is not allowed in sports competitions. However, there are several alternative statin medications available, such as Crestor, Zocor, and Pravachol, which can be considered depending on an individual's specific medical needs and under the guidance of a healthcare professional [2][3].
