RE: To achieve a pharmacolgic effect

Cindy:

This is a good question to address to the Vet Committee rather than to the
AERC as a whole. Realize that with the difference in metabolism in animals
the non-therapeutic level for one horse is highly therapeutic for another
one.

I get light headed on one beer and I have friends (?) that have no effect on
one six-pack

Then, the list of precluded substances includes not only drugs (as
understood by laypersons) but also masking substances that have no
therapeutic effect in the slightest. Take penicillin, no effect on
performance in the slightest but the carrier and the procaine are the
culprits. The carrier for its masking ability and the procaine for its
analgesic proclivity.  As one delves into the subject it becomes very
complicated but interesting in all the side issues. I would suggest some
reading on the subject such as Drugs and the Performance Horse by Tobin.
Very enlightening. You may also desire to investigate Equine Drugs and
Vacines by Kellon. If you are really interested try Clinical Chemistry and
Pathophysiology by Coffman.

One final note, you chances of being drug tested (except in California) are
about equal to your chances of getting a traffic ticket, and I know you
exceed the speed limit on occasion.

The list of impermissable substances posted on endurance.net includes:
"nutrient substances administered in doses to achive a pharmacologic effect
(DMSO, DMG, yucca and MSM)"

So, if a rider is supplementing biotin, and the biotin mix includes some
yucca, does that constitute a 'nutrient (yucca) administered in doses to
achieve a pharmocoligic effect?'

We seem to have a disconnect here between "to achieve a pharmacologic
effect" and the trace evidence that can be detected in current drug
testing.  I realize that it is not possible to predict how long a substance
will remain in the body of a particular horse, but could we not define the
levels that constitute a "a pharmacologic effect?"

Again, the intent here is not to try to get away with anything or to
compete a horse that is still recovering from an illness or injury.  Just
don't want to end up in violation of drugs restrictions because my horse
was sedated to have his teeth floated or because I used the wrong biotin
supplement.
