Equine Veterinary Journal, Volume 58, Issue 5, Page 1363-1371, September 2026.
Abstract Background Current treatment options for equine gastric ulcer syndrome (EGUS), such as omeprazole—a proton pump inhibitor (PPI)—have notable limitations, including the need for administration on an empty stomach. Potassium‐competitive acid blockers (P‐CABs), such as vonoprazan, are a newer class of acid suppressants that offer several ...
