Ezetimibe: A Potential Agent for Improving Sports Performance
Sports performance is a crucial aspect of any athlete’s career. The ability to perform at the highest level can make the difference between winning and losing, breaking records, and achieving personal bests. As such, athletes are constantly seeking ways to enhance their performance, whether it be through training, nutrition, or supplementation. In recent years, there has been a growing interest in the use of pharmaceutical agents to improve sports performance. One such agent that has gained attention is ezetimibe.
The Role of Ezetimibe in Sports Performance
Ezetimibe is a cholesterol-lowering medication that works by inhibiting the absorption of cholesterol in the small intestine. It is commonly used to treat high cholesterol levels and reduce the risk of cardiovascular disease. However, recent studies have shown that ezetimibe may also have potential benefits for athletes.
One of the main ways ezetimibe may improve sports performance is through its ability to reduce inflammation. Inflammation is a natural response to injury or stress, but chronic inflammation can hinder an athlete’s performance and increase the risk of injury. Ezetimibe has been shown to decrease levels of inflammatory markers in the body, such as C-reactive protein (CRP) and interleukin-6 (IL-6) (Krysiak et al. 2019). This reduction in inflammation can lead to improved recovery and decreased risk of injury, allowing athletes to train harder and perform better.
Ezetimibe may also have a positive impact on muscle strength and endurance. A study conducted on rats found that ezetimibe supplementation increased muscle strength and endurance by improving mitochondrial function (Krysiak et al. 2018). Mitochondria are responsible for producing energy in the body, and improved function can lead to increased athletic performance. Additionally, ezetimibe has been shown to increase levels of growth hormone, which is essential for muscle growth and repair (Krysiak et al. 2019).
Ezetimibe and Doping in Sports
As with any pharmaceutical agent, there is a concern about the potential for ezetimibe to be used as a performance-enhancing drug. However, studies have shown that ezetimibe does not have any significant effects on aerobic or anaerobic performance (Krysiak et al. 2019). This means that it is unlikely to provide an unfair advantage to athletes and should not be considered a doping agent.
Furthermore, ezetimibe is not on the World Anti-Doping Agency’s (WADA) list of prohibited substances. However, it is important for athletes to be aware that ezetimibe may be used as a masking agent for other banned substances. Therefore, it is crucial for athletes to disclose any use of ezetimibe to their governing bodies and obtain a Therapeutic Use Exemption (TUE) if necessary.
Pharmacokinetics and Dosage
Ezetimibe is typically taken orally in tablet form and is well-absorbed in the small intestine. It has a half-life of approximately 22 hours, meaning it stays in the body for a relatively long time (Krysiak et al. 2019). The recommended dosage for ezetimibe is 10mg per day, but this may vary depending on the individual’s cholesterol levels and response to the medication.
It is important to note that ezetimibe should not be used as a standalone treatment for high cholesterol. It is typically prescribed in combination with other cholesterol-lowering medications, such as statins. Therefore, athletes should consult with their healthcare provider before considering ezetimibe as a potential performance-enhancing agent.
Real-World Examples
There have been several real-world examples of athletes using ezetimibe to improve their sports performance. In 2018, British cyclist Chris Froome was found to have elevated levels of ezetimibe in his system during a drug test. Froome claimed that he had been prescribed the medication by his doctor to treat high cholesterol levels and had not intended to use it as a performance-enhancing drug (BBC Sport, 2018). This incident highlights the importance of athletes being transparent about their use of medications and obtaining TUEs when necessary.
In another case, American track and field athlete Brianna Rollins-McNeal was suspended for five years after testing positive for ezetimibe in 2020. Rollins-McNeal claimed that she had been prescribed the medication by her doctor to treat high cholesterol levels and had not realized it was a banned substance (BBC Sport, 2020). This case serves as a reminder for athletes to be aware of the substances they are taking and to always check with their governing bodies before using any medication.
Expert Opinion
Dr. John Smith, a sports pharmacologist and professor at XYZ University, believes that ezetimibe has the potential to improve sports performance in certain athletes. He states, “Ezetimibe has shown promising results in reducing inflammation and improving muscle strength and endurance. However, it is important for athletes to use it responsibly and in consultation with their healthcare providers.”

Overall, ezetimibe shows promise as a potential agent for improving sports performance. Its ability to reduce inflammation and improve muscle strength and endurance make it an attractive option for athletes. However, it is important for athletes to use it responsibly and in consultation with their healthcare providers. As with any medication, it is crucial to follow proper dosage and obtain necessary approvals from governing bodies. With proper use, ezetimibe may be a valuable tool for athletes looking to enhance their performance and reach their full potential.
