o-Mep-ruh-zol - Pronunciation guide
Omeprazole is used to prevent ulcers in horses and is also FDA approved to treat existing stomach ulcers. Studies have shown that more than 90% of race horses and more than 60% of performance horses experience gastric ulcers. The stress brought about through changes in routine, diet, and exercise regimens, along with traveling and competition, may contribute to their development. Omeprazole suppresses acid production in the horse's stomach by acting as a gastric acid (proton) pump inhibitor.
Omeprazole is mainly used to prevent ulcers in horses that are subjected to stress or other conditions that make them prone to stomach ulcers. It is also used to treat cases of existing ulcers. Omeprazole is sometimes prescribed as a precaution when NSAIDs, corticosteroids, and other drugs known to cause stomach ulcers are administered. Maximum suppression of acid production occurs three to five days after beginning treatment.
