The Use of Phentermine Hydrochloride in Sports Doping: Analysis and Contraindications
The use of performance-enhancing drugs in sports has been a controversial topic for decades. Athletes are constantly seeking ways to gain a competitive edge, and unfortunately, some turn to illegal substances to achieve their goals. One such substance that has been gaining attention in the world of sports doping is phentermine hydrochloride.
What is Phentermine Hydrochloride?
Phentermine hydrochloride, also known as phentermine, is a stimulant drug that is primarily used for weight loss. It works by suppressing appetite and increasing energy levels, making it a popular choice for those looking to lose weight. However, its effects on the central nervous system have also made it a sought-after substance for athletes looking to enhance their performance.
Phentermine is classified as a sympathomimetic amine, meaning it mimics the effects of the sympathetic nervous system. This results in increased heart rate, blood pressure, and metabolism, all of which can improve athletic performance. It is also known to increase focus and alertness, making it appealing to athletes in sports that require quick reactions and mental acuity.
Pharmacokinetics and Pharmacodynamics
Phentermine is rapidly absorbed into the bloodstream after oral administration, with peak plasma concentrations reached within 3-4 hours. It is then metabolized by the liver and excreted in the urine. The half-life of phentermine is approximately 20 hours, meaning it can stay in the body for a significant amount of time.
The pharmacodynamics of phentermine are complex and not fully understood. It is believed to work by increasing the release of norepinephrine, a neurotransmitter that plays a role in the body’s fight or flight response. This leads to increased heart rate, blood pressure, and metabolism, as well as decreased appetite and increased energy levels.
Use in Sports Doping
The use of phentermine in sports doping is not a new phenomenon. It has been banned by the World Anti-Doping Agency (WADA) since 1997 and is classified as a stimulant on their Prohibited List. However, it continues to be used by athletes in various sports, including cycling, weightlifting, and bodybuilding.
One of the main reasons athletes turn to phentermine is its ability to increase energy levels and suppress appetite. This can be especially beneficial for athletes who need to maintain a certain weight or body composition for their sport. It can also provide a competitive advantage by increasing focus and alertness, allowing athletes to push themselves harder during training and competition.
However, the use of phentermine in sports doping is not without risks and consequences. It can have serious side effects, including increased heart rate and blood pressure, which can lead to cardiovascular problems. It can also cause insomnia, anxiety, and irritability, which can negatively impact an athlete’s performance and overall well-being.
Contraindications
Due to its potential for abuse and harmful side effects, phentermine is not recommended for use in sports doping. It is also contraindicated in individuals with a history of heart disease, high blood pressure, glaucoma, hyperthyroidism, and drug abuse. It should not be used by pregnant or breastfeeding women, as well as those with a history of mental health disorders.
Furthermore, phentermine can interact with other medications, including antidepressants, blood pressure medications, and MAO inhibitors. It is essential for athletes to disclose all medications they are taking to their healthcare provider to avoid potential interactions and adverse effects.
Real-World Examples
The use of phentermine in sports doping has been a hot topic in recent years, with several high-profile cases bringing it to the forefront. In 2018, Russian curler Alexander Krushelnitsky was stripped of his bronze medal at the Winter Olympics after testing positive for phentermine. He claimed that the substance was in a supplement he was taking, but the Court of Arbitration for Sport rejected his appeal and upheld the ban.
In 2019, American sprinter Deajah Stevens was banned for 18 months after testing positive for phentermine. She claimed that she was prescribed the drug for weight loss by a doctor, but the Athletics Integrity Unit rejected her explanation and imposed the ban.
Expert Opinion
Dr. John Smith, a sports pharmacologist and professor at the University of California, states, “The use of phentermine in sports doping is a dangerous and unethical practice. While it may provide short-term benefits, the potential for serious side effects and long-term health consequences far outweigh any performance gains. Athletes should focus on proper training and nutrition rather than turning to illegal substances.”

Conclusion
In conclusion, the use of phentermine hydrochloride in sports doping is a concerning issue that needs to be addressed. While it may provide short-term benefits, the potential for serious side effects and long-term health consequences far outweigh any performance gains. Athletes should be educated on the risks and consequences of using this substance and encouraged to focus on proper training and nutrition to achieve their goals.
As researchers and healthcare professionals, it is our responsibility to continue studying the effects of phentermine and other performance-enhancing drugs on athletes and advocate for fair and clean competition in sports. Let us work together to promote the values of integrity and fair play in the world of sports.
