New Educational Videos Provide Important Equine Stomach Ulcer Information

With two out of three competitive horses suffering from equine stomach ulcers,1 horse owners need access to important information about:

  • Understanding how ulcers occur
  • Recognizing the clinical signs of ulcers
  • Preventing and treating ulcers
  • Knowing which products are effective

Now, this information is available in a new series of three easy-to-understand videos:

1. Why Equine Stomach Ulcers Happen
A horse’s stomach can produce up to 16 gallons of acid each day.2 A high-roughage diet, found in natural grazing environments, results in a decreased level of acid due to a buffering effect of the grass and the horse’s own saliva. However, many horses are stalled with limited turnout and fed fewer, larger meals, including grain. These situations can cause acid levels to rise in a horse’s stomach. This video also addresses other causes and risk factors that horse owners should know.

2. Preventing and Treating Equine Stomach Ulcers
Stomach ulcers have been identified in horses of all breeds, disciplines and ages.3 They can be prevented with the use of ULCERGARD (omeprazole), the only proven and FDA-approved product for the prevention of equine stomach ulcers.4 ULCERGARD works by blocking the production of excess acid. For the treatment of equine stomach ulcers, the only proven and FDA-approved product is GASTROGARD (omeprazole)5. Horse owners can learn more about prevention and treatment in this video.

3. Why Most Equine “Ulcer” Products Aren’t Worth the Gamble
There are dozens of products claiming to prevent and/or treat equine stomach ulcers. These products are often falsely advertised as “generic” or “just as good as” ULCERGARD or GASTROGARD. However, there are no generic versions of either drug. In one study, five such products were tested and found to have formulations as low as just 63% of the labeled active ingredient (omeprazole).4 This segment will help horse owners learn about the types of products available and about the importance of choosing those that are FDA-approved.

“Owners have a tremendous emotional and financial investment in their horses, and want what’s best for them,” said Megan Green, DVM, manager, equine and large animal veterinary services, Merial. “Being educated and understanding equine stomach ulcers is important for the animal’s overall health.”
