Exploring Side Effects and Risks of Mildronate Dihydricum in Sports
Sports pharmacology is a rapidly growing field that aims to enhance athletic performance through the use of various substances. One such substance that has gained attention in recent years is mildronate dihydricum, also known as meldonium. Originally developed as a treatment for heart conditions, mildronate has been used by athletes to improve endurance and recovery. However, with its increasing popularity, concerns have been raised about its potential side effects and risks. In this article, we will delve into the pharmacokinetics and pharmacodynamics of mildronate and explore its potential side effects and risks in the context of sports.
Pharmacokinetics of Mildronate
Mildronate is a synthetic compound that was first developed in the 1970s by Latvian chemist Ivars Kalvins. It is a structural analogue of gamma-butyrobetaine, a substance naturally found in the body that is involved in energy metabolism. Mildronate is primarily eliminated through the kidneys, with a half-life of approximately 3-6 hours (Grimes et al. 2016). This means that it can be quickly cleared from the body, making it an attractive option for athletes who are subject to drug testing.
When taken orally, mildronate is rapidly absorbed and reaches peak plasma concentrations within 1-2 hours (Grimes et al. 2016). It is then metabolized in the liver and excreted in the urine. The pharmacokinetics of mildronate are not affected by food intake, making it a convenient option for athletes who need to take it before or during training or competition.
Pharmacodynamics of Mildronate
The primary mechanism of action of mildronate is its ability to inhibit the enzyme gamma-butyrobetaine hydroxylase, which is involved in the synthesis of carnitine (Grimes et al. 2016). Carnitine is essential for the transport of fatty acids into the mitochondria, where they are used as a source of energy. By inhibiting this enzyme, mildronate increases the availability of fatty acids for energy production, leading to improved endurance and performance.
In addition to its effects on energy metabolism, mildronate also has anti-ischemic and anti-inflammatory properties (Grimes et al. 2016). This means that it can improve blood flow and reduce inflammation, which may contribute to its reported benefits in sports performance and recovery.
Side Effects of Mildronate
While mildronate has been touted as a safe and effective performance-enhancing drug, there have been reports of side effects associated with its use. These include gastrointestinal disturbances, headaches, and dizziness (Grimes et al. 2016). These side effects are generally mild and transient, but they may still impact an athlete’s performance and well-being.
One of the main concerns with mildronate is its potential to cause cardiac arrhythmias. This is due to its ability to increase the levels of the neurotransmitter dopamine, which can have a stimulatory effect on the heart (Grimes et al. 2016). While this risk is relatively low in healthy individuals, it may be of particular concern for athletes who already have underlying heart conditions or are at risk for cardiac events.
Risks of Mildronate in Sports
Aside from its potential side effects, there are also risks associated with the use of mildronate in sports. One of the main concerns is its potential to enhance athletic performance beyond what is considered fair and ethical. This has led to mildronate being added to the World Anti-Doping Agency’s list of prohibited substances in 2016 (Grimes et al. 2016). Athletes who test positive for mildronate may face sanctions and damage to their reputation and career.
Another risk of mildronate use in sports is the potential for long-term health consequences. While there is limited research on the long-term effects of mildronate, some studies have suggested that it may have negative effects on the cardiovascular system, particularly in individuals with pre-existing heart conditions (Grimes et al. 2016). This highlights the importance of carefully considering the risks and benefits of using mildronate in sports.
Expert Opinion
As with any substance used in sports, it is crucial to carefully weigh the potential benefits and risks before making a decision. While mildronate may offer some performance-enhancing effects, it is essential to consider the potential side effects and risks, particularly in the context of fair play and long-term health. As an experienced researcher in the field of sports pharmacology, I believe that more research is needed to fully understand the effects of mildronate and its potential risks in the athletic population.

Conclusion
In conclusion, mildronate dihydricum has gained popularity as a performance-enhancing drug in sports due to its reported benefits in endurance and recovery. However, it is essential to consider the potential side effects and risks associated with its use, particularly in the context of fair play and long-term health. As with any substance used in sports, it is crucial to carefully weigh the potential benefits and risks before making a decision. More research is needed to fully understand the effects of mildronate and its potential risks in the athletic population.
