STATE HORSE RACING COMMISSION
Schedule of Controlled Therapeutic Medications for Standardbred Horse Racing
[54 Pa.B. 2050]
[Saturday, April 13, 2024]The State Horse Racing Commission (Commission), in accordance with its general authority and jurisdiction over pari-mutuel horse racing activities within this Commonwealth and under 3 Pa.C.S. § 9312(6)(i) (relating to additional powers of Commission), updates the Schedule of Controlled Therapeutic Medications for Standardbred Horse Racing (Therapeutic List) as established by the Nationally-recognized Association of Racing Commissioners International and the Racing Medication and Testing Consortium set forth as follows.
The general purpose of the notice is: (1) to provide up-to-date scientific information to this Commonwealth's standardbred racing industry related to the use of therapeutic medications and the respective threshold levels of those medications, (2) to bring uniformity to this Commonwealth's standardbred industry and its horsemen as it relates to the permitted use of therapeutic medications under the threshold levels in the Therapeutic List and (3) to create uniformity and consistency within the regulatory bodies of the Mid-Atlantic racing states regarding the use and detection of allowable therapeutic medications.
The Therapeutic List was previously adopted and published by the Commission at 48 Pa.B. 1662 (March 17, 2018). The approved list of 30 therapeutic medications and threshold levels will take effect upon publication in the Pennsylvania Bulletin.
This notice and Therapeutic List have been posted and published on the Commission's web site and a copy may be accessed at https://www.agriculture.pa.gov/Animals/RacingCommission/PA%20State%20Harness%20Racing/Pages/default.aspx. The Commission will also provide copies of the notice upon request directed to (717) 787-5539.

[Pa.B. Doc. No. 24-533. Filed for public inspection April 12, 2024, 9:00 a.m.] _______
1Note: Administration of albuterol other than by intra-nasal routes is not recommended.
2 Note: Clenbuterol should not be administered within 96 hours of racing.
3An oral dose may be utilized but a longer withdrawal time may be required to fall below the threshold. Trainers using methocarbamol orally for multiple days are encouraged to have the horse tested prior to entry.
4At the 100 mg experimental dose, the safe time for administration to fall below the 100 pg/mL threshold was 21 days—a smaller dose may be utilized which may allow plasma concentrations to fall below the threshold in fewer than 21 days.
5Requires: 1. Mandatory notification of procaine penicillin administration and 2. Mandatory surveillance at the horse owner's expense for 6 hours before racing. Contact an individual's local racing jurisdiction for specific procedures.
