Misoprostol is a drug used in horses to prevent ulcers from developing in the hindgut and stomach. It is commonly prescribed to horses that require regular use of non-steroidal anti-inflammatory drugs (NSAIDS), which can cause ulcers to form.
Misoprostol is also used to treat gastric ulcers in the stomach’s glandular region in horses that are not responding to conventional treatments, such as omeprazole or sucralfate.
