Merneith Split Sample Confirms Presence of Dextrorphan

A hearing has been set for November 12 before the California Horse Racing Board’s Board of Stewards after a split sample confirmed a positive result for the presence of Dextrorphan, a cough suppressant, in the sample from the Bob Baffert-trained Merneith (American Pharoah), who was second in the fourth race at Del Mar July 25, 2020.

“Unfortunately, it’s just another case of contamination,” Craig Robertson, Baffert’s attorney, told the TDN. “One of Bob’s grooms had COVID, and he was the groom who was handling Merneith. He was taking both DayQuil and NyQuil and that’s where you find Dextrorphan. it’s a cough suppressant. You would never give a cough suppressant to a horse. It’s another case of clear contamination, along with these others, and it’s just unfortunate that all of these have occurred within a relatively short time frame.

According to Wikipedia, Dextrorphan “is a psychoactive drug of the morphinan class which acts as an antitussive or cough suppressant and dissociative hallucinogen.” It is contained in DayQuil, NyQuil, Robitussin and other popular cough suppressants.

According to the CHRB complaint, posted on their website, “the Official Blood Sample #DM15986 taken on 7/25/20, was reported by Dr. Ben Moeller of the Maddy EACL at UC Davis to contain Dextrorphan, a metabolite of Dextromethorphan. This sample was taken from the horse MERNEITH which ran in the 4th race at Del Mar that day and finished 2nd. Dextrorphan, a metabolite of Dextromethorphan, is a prohibited drug if detected in a horse’s blood or urine when tested following a race. The trainer of record is Bob Baffert. A split sample was requested by Baffert, which confirmed the original violation. Dextrorphan, a metabolite of Dextromethorphan, is a Class 4 drug with a Penalty Category B.”

“A number of my staff were sick with COVID this summer, including Merneith’s groom,” Baffert said via email to the Paulick Report, which was the first to report the story. “I learned he had been taking over-the-counter cough syrups that contained Dextrorphan. This has been an issue in other states where contamination has lead to positive tests. That’s what happened here. This is clearly another case of contamination. Ultimately, this is my responsibility. It’s really embarrassing for the barn, but that’s what happened. #2020 sucks.”

The CHRB explained that the posting of this level of complaint was indicative of a new, more transparent policy.

“The California Horse Racing Board has expanded the posting of complaints on its website for alleged medication violations to include Class 4 and Class 5 violations,” said the CHRB in a press release. “The CHRB has been posting complaints for the more serious Class 1, 2, and 3 violations, which require disqualifications and forfeiture of purses. However, with the increased emphasis on all medication violations in horse racing, the CHRB has elected to add Class 4 and Class 5 complaints as well. The complaints stem from all drug testing, including alleged violations during racing, training, and from out-of-competition testing. To view complaints filed by the CHRB, go to the website (www.chrb.ca.gov) and click on the tab for Administrative Actions, then select Complaints from the drop-down menu.”

The CHRB cautioned that the posted rulings are not yet final.

“Be aware that complaints are filed for alleged violations prior to hearing. The cases have not been adjudicated at the time they are posted. Pursuant to a new statute, potential medication violations will be posted on the CHRB website beginning January 1, 2021, with the identification of all drug positives once the split sample is confirmed or even earlier if the licensee declines to request split-sample testing. Those positives will be posted before any complaints are issued.”

‘Clearly Another Case Of Contamination’: CHRB Complaint Reveals Dextorphan Positive In Baffert Trainee

The California Horse Racing Board (CHRB) has filed a complaint against Baffert after his trainee Merneith tested positive for dextorphan this summer. Merneith, who earlier this year was third in the Grade 2 Santa Anita Oaks, received the positive test post-race after she finished second in the fourth race on Del Mar's July 25 card. Baffert trains the daughter of American Pharoah for HRH Prince Sultan Bin Mishal Al Saud.

A split sample confirmed the original violation, according to the Sept. 17 CHRB complaint.

Baffert said the finding was a result of environmental contamination.

“A number of my staff were sick with COVID this summer, including Merneith's groom,” Baffert said via email. “I learned he had been taking over-the-counter cough syrups that contained Dextrorphan. This has been an issue in other states where contamination has lead to positive tests. That's what happened here. This is clearly another case of contamination. Ultimately, this is my responsibility. It's really embarrassing for the barn, but that's what happened. #2020 sucks.”

Dextorphan is a metabolite of dextromethorphan, which is a Class 4 drug according to the Association of Racing Commissioners International's classification system. Class 4 drugs are primarily therapeutic drugs which “may influence performance but generally have a more limited ability to do so” as compared to those in other classes. Dextromethorphan is a common ingredient in human cough syrups, though it can also be a drug of abuse, given its capacity to act as an anesthetic in high doses. It has no Food and Drug Administration-approved use in the horse, but regulators have been told it has been used experimentally to quiet nervous behaviors like cribbing.

The metabolism of dextorphan and dextromethorphan were the subject of a study several years ago in Kentucky. The research found that dextromethorphan breaks down quickly in a horse's body, turning it into dextorphan. But unlike some other substances, dextorphan briefly increases in the horse's system as the dextromethorphan breaks down, and then it tapers off more gradually than testing experts had previously realized. The research in Kentucky led to three dextorphan positives being dismissed — not because the commission agreed they were the result of environmental contamination, but rather because it was unclear when the horses had been exposed to dextromethorphan, given the study results about the drug metabolism.

Dextorphan carries a penalty category of B, which has variable suspension lengths depending upon the number of previous violations within a 365-day period.

News of the dextorphan positive comes hard on the heels of an acknowledgement by Baffert that Gamine tested positive for betamethasone following her third-place effort in the G1 Kentucky Oaks this year. Split sample testing in that case has not yet been completed, but Baffert's attorney maintains the drug was administered in the recommended timeframe outlined by Kentucky's rules. Gamine and Charlatan also tested positive for lidocaine following races at Oaklawn this spring, which Baffert attributed to environmental contamination from an employee's over-the-counter pain patch. He told media he planned to appeal those rulings by Arkansas stewards.

Little Movement In NTRA 3-Year-Old, Top Thoroughbred Polls Ahead Of Breeders’ Cup

Less than two weeks out from the Breeders' Cup World Championships at Keeneland on Nov. 6-7, there was little change in both the latest National Thoroughbred Racing Association (NTRA) Top 3-Year-Old Thoroughbred Poll and NTRA Top Thoroughbred Poll.

Ahead of his expected start in the $6 million Breeders' Cup Classic, Kentucky Derby winner Authentic continues to hold down the top spot in the Three-Year-Old Poll with 15 first-place votes and 330 points. The son of Into Mischief tuned up for the Breeders' Cup with a seven-furlong breeze in 1:24.40 at Santa Anita Park on October 24, his second timed workout since finishing second in the Oct. 3 Preakness Stakes.

Belmont and Travers Stakes winner Tiz the Law is also slated to be one of the top contenders for the Breeders' Cup Classic and moved back into the No. 2 spot on the poll this week with 10 first-place votes and 323 points. The son of Constitution arrived at Keeneland last week where he worked six furlongs in 1:13.20 on Oct. 23.

Preakness Stakes heroine Swiss Skydiver, who remains under consideration for either the Breeders' Cup Distaff or Classic, dips one spot this week to third with 11 first-place votes and 318 points. Grade 2 winner Art Collector (193 points) ranks fourth, ahead of Grade 1 Jockey Club Gold Cup winner Happy Saver (178).

Grade 1 winner Honor A. P., who was retired last month to Lane's End Farm, remains sixth with 120 points followed by multiple Grade 1 winner Gamine (94 points), who is expected to contest the Breeders' Cup Filly & Mare Sprint.

Max Player takes over sole possession of the eighth spot this week with 77 points, one point ahead of Kentucky Oaks winner Shedaresthedevil (76). Mystic Guide, who was second in the Jockey Club Gold Cup, rounds out the top 10 with 67 points.

Multiple Grade 1 winner and likely Breeders' Cup Classic favorite Improbable maintains his lead in the NTRA Top Thoroughbred Poll with 31 first-place votes and 355 points. Trained by Bob Baffert, Improbable will bring a three-race win streak into the Classic and clocked a seven-furlong work in 1:25 on Oct. 25.

Champion Maximum Security remains behind his stablemate in the poll with 2 first-place votes and 262 points. Multiple Grade 1 winner Vekoma (1 first-place vote, 217 points) remains third with expected Breeders' Cup Classic contender Tom's d'Etat (2 first-place votes, 213 points) in fourth.

Monomoy Girl, the champion 3-year-old filly of 2018, holds in fifth with 197 points followed by multiple graded stakes winner By My Standards (138 points). Authentic (119 points) and Tiz the Law (116) rank seventh and eighth, respectively, with Swiss Skydiver (101) and multiple Grade 1 winner Rushing Fall (67) completing the top 10.

The NTRA Top Thoroughbred polls are the sport's most comprehensive surveys of experts. Every week eligible journalists and broadcasters cast votes for their top 10 horses, with points awarded on a 10-9-8-7-6-5-4-3-2-1 basis. All horses that have raced in the U.S., are in training in the U.S., or are known to be pointing to a major event in the U.S. are eligible for the NTRA Top Thoroughbred Poll. Voting in both the Top Three-Year-Old Thoroughbred Poll and the Top Thoroughbred Poll is scheduled to be conducted through the conclusion of the Breeders' Cup in November.
