Horsemen Reminded To Avoid Using Products Containing Levamisole and Tetramisole

Levamisole and tetramisole are sold as wormers for farm livestock and are also sometimes marketed as “immune stimulants” or “immune modulating” substances over the internet and in tack shops. Levamisole is classified by the Association of Racing Commissioners International’s Uniform Classification Guidelines as a Class 2, Penalty Class B substance while tetramisole is not currently classified.

There is very strong evidence in the scientific literature, however, that the administration of levamisole, and potentially tetramisole, to horses results in production of aminorex and pemoline as metabolites. Aminorex and pemoline are both Penalty Class A substances, which carry a minimum one-year suspension if detected in a post-race sample. Levamisole was linked to a significant number of aminorex positive tests in 2007 and advisories were issued to horsemen to avoid levamisole administration at the time.

Horsemen's Recreation Program Expands

Dan Mangum is a busy guy who prides himself on all he does for the backstretch workers, primarily at Laurel Park.

A high school coach, he is responsible for recreational activities and special events at the track. Since March, he has been driving a nine-passenger van, taking backstretch workers – the life­blood of the tracks – to doctors’ appoint­ments and more, as the Maryland Thoroughbred Horsemen’s Association and track management responded to the workers’ request for transportation.

But Mangum, 68, is just one man – albeit one very busy man. So the MTHA has brought in Marty Leonard to shoulder some of the load.

Jockey agent for Sheldon Russell and Jevian Toledo, Leonard, 33, will help manage the sports activities for the backstretch workers.

Concussions- A Major Focus of Horsemen’s Health System

Agent Frankie Douglas, a former jockey, recalls he had a head injury while riding at Timonium in 1997. When he finally came back to riding, eight months later, it was with a doctor’s OK, but he adds “even then, it wasn’t a good idea.”

When Douglas, now 55, rode, there were no restrictions for concussions.

“If my head hurt or my leg hurt I had to ride,” he says. “Now, MedStar pays more attention to the riders than before. They take you off the horses until you do all the [protocols]. If you are not OK, they won’t let you ride. This is very, very good.

“Jockeys are athletes and need to be taken care of. . . Head injuries, we should take all the precautions necessary . . . It is the right thing to do.”

Last October, Maryland became the first state in the country to establish a protocol for concussions at its thoroughbred racetracks when the Maryland Thoroughbred Horsemen’s Association and Maryland Jockey Club launched the Horsemen’s Health System in conjunction with MedStar Sports Medicine.

But because there had – fortunately – been no head injury incidents until mid-April, jockeys and other horsemen were caught by surprise when a jockey, after being thrown from his mount and hitting his head, was told he would not be riding until he completed the protocol.

Any jockey who sustains a head trauma or suspected head trauma and exhibits any physical, cognitive, emotional or sleep symptoms must wait at least 72 hours and be symptom free before passing through the protocol, which consists of five phases.
