I was wondering if there was an equine version of the product Trisenox®. I have reason the believe that at one of my previous barns, this product was injected via vein into the horse's blood stream in order for a horse to let go of his/ her hair faster. Virtually taking a horse from inch long hair to microscopic fur within a week or so. I have heard several mentions of the name that it may be marketed under, "Western Horseman Sreum," but I am not exactly sure if that is what it is being labled under. If anyone has any information regarding this, please include your findings. Here is the link to where I found Trisenox®: http://www.fda.gov/cder/consumerinfo/druginfo/Trisenox.HTM

A few of the mani questions that I would like answered about this product are:

~Is it legal to own with or without a permit?
~Is it same to administer to an equine?
~Does it show up in blood/ drug tests?

I do not personally use this drug, nor any like it, but I am concerned that a barn that I was previously at did in regard to their show animals. I am very concerned and would to get to the bottom of this. Owners of this barn also have other various drugs in their possesion, many of which may require permits and/or a liscense to use. Both of which I doubt he has in his possesion.

:D Thank you for your time.

Well, Trisenox is arsenic trioxide, so I doubt you can obtain it OTC. Is it possible that they were using something like Pergolide, which is used to treat Cushing's disease, and could cause shedding? I imagine that arsenic would show on a blood test, but it's hard to say whether they test for toxins or just for performance-enhancing drugs.

It may have been possible that they were using Pregolide, but I do bleive that that drug is now prohibited. I could be wrong though. Either way, none of the horse's at the barn had Cushings.

Peroglide isn't prohibited. It's widely used in treatment of Cushing's. It may be prohibited for showing but I don't see why it would be. My point though was that it might be a legal, if not terribly ethical, way to make a horse shed rapidly (I don't even know if it would work; just throwing it out there). I haven't seen anything that says arsenic would make a horse lose coat though (it causes hair loss in humans, but only at toxic doses).
