Phenylbutazone (PBZ) is a nonsteroidal antiinflammatory drug (NSAID) that is not commonly prescribed due to the high incidence of serious adverse reactions. However, it is still used extensively in equine medicine, and is readily available to those employed in the care and management of horses. Such persons may take the drug indiscriminately, without medical supervision. We present a 33-year-old male race horse track worker who took phenylbutazone horse pills for a chronic toothache and subsequently suffered a major hemorrhage from a gastric ulcer. Human use of phenylbutazone horse pills should be considered by physicians confronted with patients who have upper gastrointestinal symptoms and gastric injury and who belong to this select group.

Gastric ulcer induced by the injection of acetic acid (0.025 ml of 20%) into the gastric wall of rats was healed considerably 5 days after the injection of acetic acid. Non-steroidal anti-inflammatory drugs (NSAID) such as aspirin, indomethacin, and phenylbutazone were given consecutively for 5 days, and they exacerbated the ulcer and enlarged the ulcer area. Aspirin caused exacerbation when it was given for the initial 5 days of the ulcer healing process. Phenylbutazone caused exacerbation by the administration for 5 days at the middle stage of the ulcer healing process. In contrast, indomethacin caused exacerbation not only when it was given for the initial 5 days but also when it was given for the middle 5 days. The effect of the antiulcer agent N-acetyl-L-glutamine aluminum complex (KW-110) on the exacerbation was studied. KW-110 at an oral dose of 500 mg/kg inhibited remarkably the exacerbation induced by all of the NSAID used. The development of gastric lesions induced by these NSAID was also prevented by KW-110. Further study was carried out with regard to the influences of KW-110 on the pharmacological properties of NSAID. The results showed no influences of KW-110 on the antiedematous and antipyretic actions of the NSAID.
