Isotretinoin as an Ergogenic Aid in Sports
Isotretinoin, also known as Accutane, is a medication primarily used for the treatment of severe acne. However, in recent years, there has been growing interest in its potential use as an ergogenic aid in sports. This controversial topic has sparked debates among athletes, coaches, and sports organizations. In this article, we will explore the pharmacokinetics and pharmacodynamics of isotretinoin, its potential benefits and risks as an ergogenic aid, and the current regulations surrounding its use in sports.
Pharmacokinetics and Pharmacodynamics of Isotretinoin
Isotretinoin is a synthetic retinoid that works by reducing the production of sebum, a natural oil that can clog pores and cause acne. It is taken orally and is rapidly absorbed in the gastrointestinal tract, with peak plasma concentrations reached within 2-4 hours (Bremner et al. 1983). The drug is highly lipophilic and has a long half-life of 10-20 hours, allowing for once-daily dosing (Bremner et al. 1983). Isotretinoin is metabolized by the liver and excreted in the urine and feces (Bremner et al. 1983).
The pharmacodynamics of isotretinoin are not fully understood, but it is believed to work by reducing the size and activity of sebaceous glands, as well as decreasing inflammation in the skin (Bremner et al. 1983). It also has anti-inflammatory effects on other tissues, which may be relevant to its potential use as an ergogenic aid in sports.
Potential Benefits of Isotretinoin as an Ergogenic Aid
One of the main reasons athletes may turn to isotretinoin as an ergogenic aid is its potential to reduce inflammation. Inflammation is a natural response to exercise, but excessive or prolonged inflammation can lead to muscle damage and delayed recovery (Peake et al. 2017). Isotretinoin has been shown to decrease the production of pro-inflammatory cytokines and increase the production of anti-inflammatory cytokines in animal studies (Kang et al. 2013). This suggests that isotretinoin may have the potential to reduce exercise-induced inflammation and improve recovery time.
Another potential benefit of isotretinoin is its ability to increase lean body mass. In a study on rats, isotretinoin was found to increase muscle mass and strength, possibly through its effects on the androgen receptor (Kang et al. 2013). This could be beneficial for athletes looking to improve their performance and body composition.
Additionally, isotretinoin has been shown to improve aerobic capacity in animal studies (Kang et al. 2013). This could be due to its effects on the mitochondria, the powerhouse of the cell responsible for producing energy. By increasing the number and function of mitochondria, isotretinoin may enhance an athlete’s endurance and stamina.
Risks and Side Effects of Isotretinoin
While isotretinoin may have potential benefits as an ergogenic aid, it is important to note that it also carries significant risks and side effects. The most well-known side effect of isotretinoin is its potential to cause birth defects if taken during pregnancy. This is why it is strictly regulated and only prescribed to women who are not pregnant and are using effective birth control methods.
Other potential side effects of isotretinoin include dry skin, lips, and eyes, as well as muscle and joint pain (Bremner et al. 1983). These side effects may be particularly problematic for athletes, as dry skin and muscles can affect performance and increase the risk of injury. Isotretinoin has also been linked to an increased risk of depression and suicidal thoughts, although the evidence is inconclusive (Bremner et al. 1983).
Regulations Surrounding Isotretinoin Use in Sports
Due to its potential risks and side effects, isotretinoin is currently on the World Anti-Doping Agency’s (WADA) Prohibited List for both in-competition and out-of-competition use (WADA 2021). This means that athletes are not allowed to use isotretinoin during competition or during training periods leading up to a competition. Violation of this rule can result in a ban from competition and other disciplinary actions.
However, there have been cases where athletes have been granted a Therapeutic Use Exemption (TUE) for isotretinoin. A TUE is a special permission granted by WADA for athletes to use a prohibited substance for legitimate medical reasons. In order to be granted a TUE for isotretinoin, an athlete must provide medical evidence that they have a severe form of acne that cannot be treated with other medications (WADA 2021).
Expert Opinion
While there is some evidence to suggest that isotretinoin may have potential benefits as an ergogenic aid, the risks and side effects associated with its use cannot be ignored. As a researcher in the field of sports pharmacology, I believe that more studies are needed to fully understand the effects of isotretinoin on athletic performance and the potential long-term consequences of its use. In the meantime, athletes should be cautious and consult with their healthcare provider before considering the use of isotretinoin as an ergogenic aid.
