Piroxicam, aspirin, and gastrointestinal blood loss

Abstract
A study to compare the effects of 3 piroxicam regimens and aspirin on fecal blood loss (FBL) was conducted among 39 healthy men. Of the subjects, 14 also underwent pre- and poststudy gastroscopy. There was an increase in FBL after aspirin 972 mg 4 times/day, whereas piroxicam 20 mg/day, 5 mg 4 times/day, and 10 mg 4 times/day induced no observable increase in fecal blood loss. There was gastroscopic evidence of irritation in the aspirin group, but not in any of the piroxicam groups.
