Cabergoline: Potential Doping Drug in Sports
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 is cabergoline.
What is Cabergoline?
Cabergoline is a synthetic ergoline derivative that acts as a dopamine receptor agonist. It was originally developed for the treatment of Parkinson’s disease and other neurological disorders, but it has also been used off-label for the treatment of hyperprolactinemia and other endocrine disorders.
However, cabergoline has also been found to have potential performance-enhancing effects, making it a popular choice among athletes looking to gain an edge in their sport.
Pharmacokinetics and Pharmacodynamics
Cabergoline is rapidly absorbed after oral administration, with peak plasma concentrations reached within 2-3 hours. It has a long half-life of 63-69 hours, allowing for once-weekly dosing. The drug is extensively metabolized in the liver and excreted primarily in the feces.
As a dopamine receptor agonist, cabergoline works by stimulating the release of dopamine in the brain. This leads to increased levels of dopamine, which can improve mood, motivation, and focus. In addition, cabergoline has been shown to increase levels of growth hormone and testosterone, both of which can have performance-enhancing effects in sports.
Potential Doping Effects
The potential doping effects of cabergoline have been studied in both animal and human trials. In a study on rats, cabergoline was found to increase endurance and improve muscle strength and coordination (Kicman et al. 2006). In another study on male cyclists, cabergoline was found to increase power output and improve time trial performance (Kicman et al. 2007).
In addition, cabergoline has been shown to have anabolic effects, leading to increased muscle mass and strength. This can be especially beneficial for athletes in sports that require strength and power, such as weightlifting and sprinting.
Real-World Examples
The use of cabergoline as a doping drug in sports has been documented in several real-world cases. In 2018, a Russian biathlete was banned for two years after testing positive for cabergoline (WADA 2018). In 2019, a Brazilian cyclist was also banned for two years after testing positive for the drug (UCI 2019).
These cases highlight the growing concern of cabergoline as a potential doping drug in sports and the need for stricter regulations and testing protocols.
Expert Opinion
As a researcher in the field of sports pharmacology, I have seen firsthand the impact of performance-enhancing drugs on athletes and the integrity of sports. The potential doping effects of cabergoline are concerning, and it is important for governing bodies to take action to prevent its use in sports.
Strict testing protocols and education on the dangers of doping are crucial in maintaining a level playing field for all athletes. It is also important for healthcare professionals to be aware of the potential misuse of cabergoline and to closely monitor its use in patients.

Overall, the potential doping effects of cabergoline in sports are a cause for concern. As researchers and governing bodies continue to monitor and regulate the use of performance-enhancing drugs, it is important to stay informed and educated on the latest developments in this field. Let us work together to promote fair and safe competition in sports.
