The FDA has officially approved Gastrobin — the first generic omeprazole paste for horses — and it could completely change how equine gastric ulcers are treated.
For decades, Gastrogard and Ulcergard have dominated the equine ulcer treatment market, making omeprazole the gold standard for treating and preventing equine gastric ulcers (EGUS). But high costs have limited access for many horse owners, riders, and trainers.
Now, with the FDA approval of Gastrobin, a generic omeprazole paste for horses, the industry may finally see a shift toward more affordable, accessible ulcer treatment.
But this isn’t just a story about a new drug.
Equine gastric ulcers in performance horses
The biology of the horse digestive system
The impact of modern horse management
And the deeper question of horse welfare in today’s equestrian industry
Because if 60–90% of performance horses develop ulcers, we have to ask:
👉 Is the problem cost… or the system itself?
🐴 WHAT YOU’LL LEARN IN THIS VIDEO
In this in-depth breakdown of Gastrobin and equine gastric ulcers, we cover:
✔️ What Gastrobin is and how it compares to Gastrogard and Ulcergard
✔️ How omeprazole works in horses to treat gastric ulcers
✔️ Why equine gastric ulcers (EGUS) are so common in dressage horses, racehorses, and show jumpers
✔️ The science behind acid production in the horse’s stomach
✔️ How feeding schedules, stress, exercise, and diet contribute to ulcers
✔️ Why modern horse management increases ulcer risk
✔️ Whether cheaper treatment like Gastrobin will actually improve horse welfare
🧬 EQUINE GASTRIC ULCERS EXPLAINED
Equine gastric ulcers (EGUS) are one of the most common health problems in horses today. Studies show:
Up to 90% of racehorses develop ulcers
A high percentage of dressage horses and sport horses are affected
Even leisure horses can suffer from subclinical gastric ulcers
Because horses are designed to:
Produce continuous stomach acid
Rely on forage and saliva to buffer acidity
But modern management often includes:
Infrequent feeding schedules
Intense training and competition stress
This creates the perfect conditions for ulcer formation in the equine stomach.
💊 GASTROBIN VS GASTROGARD
With the introduction of Gastrobin, horse owners now have a generic alternative to Gastrogard.
Omeprazole (proton pump inhibitor)
Proven effectiveness in reducing gastric acid production
FDA approval for treatment and prevention of equine gastric ulcers
And that could have a major impact on:
Veterinary treatment decisions
Long-term ulcer prevention strategies
Overall equine health and welfare
⚠️ THE BIGGER ISSUE: HORSE WELFARE
While Gastrobin makes ulcer treatment more affordable, it also raises an important question:
👉 Are we solving the problem… or just managing the symptoms?
Because no medication can replace:
Turnout and natural movement
Constant access to forage
Proper feeding management
