(UPDATE AS OF 4/25/2016)
(1) On March 25, 2016, the ARCI made revisions to its “Controlled Therapeutic Medication Schedule for Horses” which you can find below.
Regulatory thresholds have been added for the following medications: 1) Cimetidine; 2)Ranitidine; 3) Cetirizine; and 4) Guaifenesin.
These new drug thresholds will NOT trigger a positive test call until June 9, 2016. The Commission will notify trainers when they have a test that will cause a positive after June 9, 2016.
IMPORTANT NOTE: Any test that would have been a positive prior to the rule change will still be positive during the transitional period.
(2) Also on March 25, 2016, the threshold levels have changed for the following:
1) Omeprazole from 1 ng/mL of urine to 10 ng/mL of plasma or serum
2) Xylazine from .01 ng/mL of plasma or serum to 200 pg/mL of plasma or serum
