metformin

A study done by the School of Veterinary Medicine at the University of California-Davis has revealed that a racehorse is likely to show a positive test result for metformin if its groom is taking the diabetes medication and urinates in the horse's stall. After a rash of metformin positives in 2024, anecdotal information surfaced that in many of these cases their grooms handling the horses had been on the drug. Metformin is used to manage blood sugar levels in people with type 2 diabetes. With the uncertainty over the metformin...

All this week, the TDN has been trying to nail down concrete details surrounding the studies performed for the Racing Medication & Testing Consortium's (RMTC) Scientific Advisory Committee (SAC) into the way metformin behaves in Thoroughbreds. It turns out that the first of the three papers stemming from this study was published Wednesday in the online journal, Drug Testing and Analysis. In short, the study finds a "prolonged detection time" for the drug. This first study involved 12 Thoroughbreds aged between two and seven years of age. It was broken...

Back in the summer of 2024, the ubiquitous type 2 diabetes drug metformin was having an oversized impact on the sport. As a banned substance, a metformin overage came with a maximum two-year ban and $25,000 fine. Among the seven metformin cases adjudicated by June of last year, the Horseracing Integrity and Welfare Unit (HIWU) had meted out three hefty suspensions including one for the maximum two years. The crux of the controversy was this: While regulators said that they had received intelligence metformin was being abused as a potential...

A new minimum reporting level (MRL) for the banned substance metformin has been proposed by HISA's Anti-Doping and Medication Control (ADMC) Committee, according to a HISA release Monday. The proposed MRL is 4.0 nanograms per milliliter in blood and is based on recommendations received at HISA and HIWU's request from the Racing Medication & Testing Consortium's (RMTC) Scientific Advisory Committee (SAC). The modification will be circulated for public comment in the coming days. Following a series of positive test results for metformin and what Monday's HISA release called, "intelligence received...

Representatives from the Horseracing Integrity and Safety Act (HISA) and the Horseracing Integrity and Welfare Unit (HIWU) hosted a Town Hall Friday to dig down into the information issued in their recent annual reports and fatality metrics. One aim of the town hall, said HISA CEO Lisa Lazarus, was to publicly "look under the hood" of the fatality numbers to better understand how they're compiled. "How do we collect these metrics? What does the process look like? Why are we very confident that they are accurate?" said Lazarus. As much...

A judge in Louisiana has dismissed Jonathan Wong's complaint against the Federal Trade Commission (FTC) and the Horseracing Integrity and Safety Authority (HISA) in the District Court for the Western District of Louisiana, Lafayette Division, ruling that the state does not have jurisdiction over HISA, according to Brent Malmstrom, one of Wong's owners. The case, which stemmed from a June, 2023 Metformin positive, saw Wong receive a two-year suspension and spurred his move to Louisiana, where the Act is not in effect. In the complaint filed Tuesday, Wong asserted that...

The Mark Glatt runner Vanzzy (Verrazano) tested positive for Metformin and Gabapentin after finishing second in a Dec. 6, 2024 $16,000 claiming race at Los Alamitos, according to a ruling posted on the Horse Racing Integrity and Welfare Unit (HIWU) website. This is the first Metformin case HIWU has had since July 2024. Glatt has denied any wrongdoing, but his lawyer, Drew Mollica, said that an internal investigation had identified a barn employee who is taking both medications. "We have not yet been served the charges, but this is another...

Defending itself in a constitutionality lawsuit initiated by the trainer Jonathan Wong, the Horseracing Integrity and Safety Authority on Friday told a federal judge in Louisiana that the court should either toss out Wong's case entirely or hold off on letting the litigation proceed while the Supreme Court of the United States decides whether it will take on one of three active requests stemming from different cases whose parties all want the nation's highest court to weigh in on similar constitutional issues Wong raises in his lower-court lawsuit. In a...

The latest development in Jonathan Wong's ongoing case stemming from a June 2023 metformin positive saw him file a complaint against the Federal Trade Commission (FTC) and the Horseracing Integrity and Safety Act (HISA) Authority in the District Court for the Western District of Louisiana, Lafayette Division. Wong is currently serving a two-year ban under HISA. In the complaint filed Tuesday, Wong asserts the Horseracing Integrity and Welfare Unit (HIWU) had threatened the immigration status of one of his intended witnesses before a prior arbitration hearing-something the agency denies doing....

The nation's racetracks appear primed for compliance with the first set of uniform receiving barn cleanliness, maintenance and security regulations. Just how stringent these rules will be remains up in the air. Back in August, the TDN took a dive into the issues that stakeholders frequently raise about the nation's fleet of receiving barns. This included the potential for unclean stalls, or receiving barns in poor overall physical condition, to cause environmental contamination through left behind trace drug residues. Last month, the Horseracing Integrity and Safety Authority (HISA) issued for...

Every week, the TDN posts a roundup of the relevant Horseracing Integrity and Safety Act (HISA)-related rulings from around the country. Among this week's rulings, several provisional suspensions have been handed out in cases pending a formal hearing. This includes trainers Frederico Villafranco and Diana Morici, who have been issued provisional suspensions for separate alleged methamphetamine positives. Trainer Francisco Ramos remains provisionally suspended with two additional alleged clenbuterol positives to go with four prior pending clenbuterol cases. Five of these cases--including the two most recent--were from out-of-competition tests. The other...

The list of trainers that have been informed by the Horse Racing Integrity and Welfare Unit (HIWU) that a horse they train has tested positive for the controversial drug Metformin has grown by two. According to postings on the HIWU website, Greg Foley and James Lawrence II have been notified that horses under their care had Metformin in their system. Lawrence's positive came from the  horse Cherished Wish (Mshawish) in a May 23 race at Penn National in which she finished second. The Foley horse to test positive was Camaro...
