Equine Pharmacology Laboratory
our mission
The Equine Pharmacology Laboratory at New Bolton Center provides accurate information to policy makers and enforcers, veterinarians, and horsemen on therapeutic and non-therapeutic drug use in race horses to help ensure the integrity of the sport, and more importantly the welfare of the horse during those intense and exciting two minutes of competition.
Overview
The Penn Vet Equine Pharmacology Laboratory works closely with the Pennsylvania Equine Toxicology and Research Laboratory (PETRL), which performs equine drug testing for racetracks in the Commonwealth. Mary Robinson is its acting director.
The PETRL group has developed methods to identify and quantify a large number of drugs in horse blood or urine. PETRL continues to develop novel methods for screening, confirming, and quantifying the presence of illegal drugs in race horse plasma or urine samples.
Because of the strong longstanding support from the PA Racing Commission(s) the Penn Vet/PETRL group has been able to provide leadership in drug testing research.


Our Research
Studies are performed to optimize clinical therapy for diseases commonly affecting race horses, and to determine the length of time needed following treatment before the horse can safely and ethically return to racing. The identification of biomarkers to monitor disease progression, and the effects of drug treatment on biomarkers, are also being pursued.

Biomarkers Help Crack the Code on Saving More Equine Lives
In both animals and humans, biomarkers can signal that something has gone awry. For clinicians, they are valuable tools – once they are identified.
