[Doping problems in horse sports--pharmacokinetics of selected antiphlogistics/analgesics relevant to doping]

Drug treatment of horses which are used in horse-racing is restricted by the regulations of the anti-doping control. Veterinarians and anti-doping control commissions are faced with the problems resulting from the discrepancy between the demand "no drugs in blood/urine of horses at the time of competition" and the need for treatment. The pharmacokinetic data of important antiphlogistics/analgetics (NSAID) for horses given in this article shall facilitate the decision of the veterinarians and commissions whether a horse having been treated with NSAID may participate in a competition or not. Further a new concept of anti-doping regulation of therapeutic substances is presented for discussion.
