[Antidoping rules in equine sports and pharmacological aspects of rule-consistent medical treatment and feeding of sport horses].

Abstract: Veterinarians play an essential role in the prevention of doping in equine sports, both as attending clinicians as well as official competition veterinarians. This complex task requires comprehensive knowledge concerning the pertinent regulations. These include official laws, such as the animal protection and medicines laws as as well as rules issued by the responsible equine sports authority. Furthermore, veterinarians are required to determine adequate withdrawal times following the legitimate use of medications in sport horses. This may be performed by applying appropriate data published by the respective equestrian sports authorities. In case such data is not available, pharmacokinetic heuristics elucidated in this article may be utilized in order to define suitable withdrawal times. Furthermore, veterinarians are recommended to advise horse owners concerning the risk of feed contaminants that may cause inadvertent positive anti-doping samples. In this context, the prevention of botanical contaminations in roughage is of importance in central Europe. Official veterinarians fulfil the task of anti-doping sampling during competitions. In order to guarantee a correct procedure, precautions for the avoidance of sample contamination are warranted and correct identification of the samples must be ensured. These procedures are described by means of the rules of the German Equestrian Federation. Tierärztinnen und Tierärzte erfüllen als Therapeuten und als Turniertierärzte besonders wichtige Aufgaben bei der Verhinderung von Doping im Pferdesport. Dies setzt umfangreiche und genaue Kenntnisse der Regularien voraus. Zu beachten sind sowohl staatliche Gesetze und Verordnungen, wie z. B. das Arzneimittel- und Tierschutzgesetz, als auch die für den jeweiligen Wettkampf anzuwendenden privatrechtlichen Verbandsregularien. Auf therapeutischer Seite steht der Tierarzt darüber hinaus insbesondere vor dem Problem, korrekte und angemessene Karenzzeiten für legitim angewendete Arzneimittel festzulegen. Dabei lassen sich für einen Teil der in der Pferdemedizin angewendeten Substanzen die von den Pferdesportverbänden veröffentlichten Werte nutzen. Stehen diese nicht zur Verfügung, können ersatzweise Karenzzeiten mithilfe pharmakokinetischer Heuristiken abgeschätzt werden, deren Anwendung in diesem Artikel erläutert wird. Darüber hinaus können Tierärzte bei der Beratung zur Sportpferdefütterung auf mögliche dopingrelevante Futtermittelkontaminanten hinweisen und so zur Vermeidung von Fällen unbeabsichtigten Dopings beitragen. In Mitteleuropa ist hier die Vermeidung botanischer Kontaminationen von Raufuttermitteln durch alkaloidhaltige Pflanzen wie Schlafmohn oder Stechapfel besonders bedeutsam. Turniertierärzten obliegt die Aufgabe der korrekten Probennahme bei der Durchführung von Anti-Doping-Kontrollen. Hierbei müssen Vorsichtsmaßnahmen zur Vermeidung einer Kontamination der Proben beachtet und genaue Abläufe zur Sicherung der Probenidentität und Probenqualität eingehalten werden. Dieses Prozedere wird am Beispiel der Regeln der Deutschen Reiterlichen Vereinigung exemplarisch erläutert.

The research article discusses the pivotal role of veterinarians in preventing doping in equine sports by utilizing comprehensive understanding of the pertinent regulations and determining suitable withdrawal times for medications. The study also highlights recommendations for preventing cases of unintentional doping due to feed contaminants, and outlines the procedures for anti-doping sampling during competitions.

Role of Veterinarians in Anti-doping

  • The research asserts that veterinarians have a crucial role in preventing doping in equine sports. They fulfil this task in their capacity as attending clinicians and official competition veterinarians.
  • Their role demands a comprehensive knowledge of the regulations regarding doping, which includes official laws, such as animal protection and medicinal laws, and rules issued by the responsible equine sports authority.

Determining Adequate Withdrawal Times

  • Veterinarians are required to accurately determine adequate withdrawal times for medications in sport horses.
  • The withdrawal time is the amount of time that needs to pass after a horse has been given a medication and before it is allowed to compete. This ensures that the effects of the medication do not give the horse an unfair advantage in the competition.
  • Appropriate data published by the respective equestrian sports authorities can help in determining these withdrawal times.
  • If such data is not available, the paper suggests pharmacokinetic heuristic methods can be used to estimate suitable withdrawal times.

Advising on the Risk of Feed Contaminants

  • The paper also suggests that veterinarians should advise horse owners on the risk of feed contaminants which could lead to inadvertent positive anti-doping samples.
  • The emphasis is placed on the prevention of botanical contaminations in roughage, which is of importance in central Europe.

Conducting Anti-Doping Sampling

  • The paper discusses the procedures for conducting anti-doping samplings during competitions, a task fulfilled by official veterinarians.
  • Precautions must be taken to avoid contamination of the samples, and correct identification of these samples must be ensured.
  • These procedures are explained in the paper using the example of the rules set by the German Equestrian Federation.
