Ulcergard, distributed by Merial, is a once-a-day ant-acid paste to be used in equine.

How it Works
Omeprazole, the active ingredient in Ulcergard, inhibits the gastric pump decreasing the amount of stomach acid produced by the horse.

Ulcerguard reduces the acidity within the stomach of the horse, preventing gastro-ulcerations.


A horse’s stomach continuously produced acidifying stomach bile to digest the species vast diet of greens. Grass, hay, and various other foods are highly known to contribute high acidity, resulting in ulcerations, sporting events contribute to these levels.  In fact, research has proven over 60% of horses have been reported with stomach ulcerations and 90% of horses engaging in racing activities. A horse with a gastric ulcer will display symptoms such as; poor performance, poor body condition, dull hair coat, diarrhea, colic, and a decrease in appetite. The stomach contains natural acidic bile fluids used to digest food. In some incidences the acidity can become too great causing irritation to the esophagus due to failed epiglottis closure, ulcerations, indigestion, or adverse reactions to particular medications. Medications are administered orally to pets in order to neutralize the acids, providing relief of the acidic formations. Ulcers form within the stomach due to the natural protective lining breaking down over time. Once the natural lining has been broke down, the acids begin eating away at the stomach lining, causing red opened wounds called ulcers.

A healthy pet requires attentive care and dedication from his/her handler. Pet handlers should be aware of the aliments related to stomach ulcers include; weight loss, anemia, abdominal pain, elevated heart rate, weakness, and melena.

Horses which encounter stressful situations on a regular basis are the most prone to developing ulcers. Race horses, performance horses, and sporting horses are at the highest percentage for gastric ulcers. The Thoroughbred, Quarter Horse, Arabian, Paint, and Appaloosa are just a few of the common breeds to develop this condition.
