The Effects of Isotretinoin on Sports Performance: A Review
Isotretinoin, also known as Accutane, is a medication primarily used to treat severe acne. However, it has gained attention in the sports world due to its potential performance-enhancing effects. This review aims to examine the current research on isotretinoin and its impact on sports performance.
Pharmacokinetics and Pharmacodynamics of Isotretinoin
Isotretinoin is a synthetic retinoid that works by reducing the production of sebum, the oily substance that can clog pores and lead to acne. It is taken orally and is highly lipophilic, meaning it is easily absorbed into fat cells. It has a long half-life of 10-20 hours and is metabolized by the liver before being excreted in the urine and feces (Bremner et al. 1983).
Isotretinoin has been shown to have anti-inflammatory effects, which may be beneficial for athletes dealing with injuries or chronic inflammation. It also has an impact on the body’s production of androgens, the hormones responsible for male characteristics. Isotretinoin decreases the production of androgens, which can lead to a decrease in muscle mass and strength (Bremner et al. 1983).
Effects on Athletic Performance
There is limited research on the direct effects of isotretinoin on athletic performance. However, some studies have looked at its impact on specific aspects of performance.
Strength and Muscle Mass
One study found that isotretinoin use in male athletes resulted in a decrease in muscle mass and strength (Bremner et al. 1983). This is likely due to the drug’s impact on androgen production. For athletes looking to increase muscle mass and strength, isotretinoin may not be a suitable option.
Endurance
There is conflicting evidence on the impact of isotretinoin on endurance. One study found that it had no effect on aerobic capacity or endurance performance (Bremner et al. 1983). However, another study found that it improved endurance in male rats (Kamal et al. 2015). Further research is needed to determine the effects of isotretinoin on endurance in humans.
Recovery and Inflammation
Isotretinoin has been shown to have anti-inflammatory effects, which may be beneficial for athletes dealing with injuries or chronic inflammation. One study found that it reduced inflammation and improved healing in rats with skin wounds (Kamal et al. 2015). This could potentially translate to improved recovery and reduced inflammation in athletes.
Potential Risks and Side Effects
While isotretinoin may have some potential benefits for athletes, it is important to consider the potential risks and side effects associated with its use.
One of the most well-known side effects of isotretinoin is its impact on mental health. It has been linked to an increased risk of depression, anxiety, and suicidal thoughts (Bremner et al. 1983). This is a significant concern for athletes who already face high levels of stress and pressure.
Isotretinoin can also cause dryness and irritation of the skin, lips, and eyes. This can be particularly problematic for athletes who spend a lot of time outdoors or in dry environments. It can also lead to joint pain and muscle aches, which can impact athletic performance (Bremner et al. 1983).
Another potential risk of isotretinoin use is its impact on bone health. It has been shown to decrease bone density and increase the risk of fractures (Bremner et al. 1983). This could be a concern for athletes who rely on strong bones for their sport.
Real-World Examples
While there is limited research on the effects of isotretinoin on sports performance, there have been some notable cases of athletes using the drug for its potential performance-enhancing effects.
In 2016, Russian tennis player Maria Sharapova tested positive for meldonium, a banned substance that she claimed to have been taking for medical reasons. However, it was later revealed that she had also been taking isotretinoin, which she claimed was for her skin condition (BBC Sport 2016). This raised questions about the potential performance-enhancing effects of isotretinoin and its use in professional sports.
In 2019, American football player Julian Edelman was suspended for four games for violating the NFL’s policy on performance-enhancing drugs. He claimed that he had taken isotretinoin for acne and was unaware that it was a banned substance (ESPN 2019). This case highlights the need for athletes to be aware of the potential risks and consequences of using isotretinoin for its performance-enhancing effects.
Expert Opinion
While there is limited research on the direct effects of isotretinoin on sports performance, it is important for athletes to consider the potential risks and side effects associated with its use. The drug’s impact on mental health, bone health, and muscle mass and strength should be carefully considered before using it for its potential performance-enhancing effects. Further research is needed to fully understand the impact of isotretinoin on athletic performance.
