FEI Announces Detection Times for Methylprednisolone Acetate



The Fédération Equestre Internationale (FEI)

has announced detection times for Methylprednisolone Acetate, a frontline treatment for lameness in the equine athlete. The findings from recently completed studies on the use of intra-articular Methylprednisolone Acetate show the detection times as 28 days for the 200mg dose and 14 days for the 100mg dose. The FEI recognises that any strategy to reduce the level of doping and medication offences must contain an element of guidance and education.

With this in mind there has been an increased effort to provide detection times for substances that are in common usage. The detection time is the time taken for an active substance administered to a horse by a specified route and dosage to fall below a level at which the FEI would declare a sample positive.

It is important to note that detection times may vary depending on dose and number of injection sites used. Please note that a detection time is not the same as a withdrawal time. The withdrawal time must be decided by the treating veterinarian and is likely to be based on the detection time plus an appropriate safety margin to allow for individual variation.
