A recently published study showed that administration of one type of compounded omeprazole suspension was ineffective in healing ulcers in racehorses, while treatment with the FDA-approved form of omeprazole (GastroGard) was effective in attenuating ulcers. The study was completed at the University of California, Davis, and appeared in the latest issue of the Journal of the American Veterinary Association (https://www.avma.org).  Findings show that horse owners trying to save money by using the particular compound used in the study aren’t helping their horses, and should spur horse owners to find out what’s in compounded medications they purchase.
