I'm only guessing, but from what I understand, Piroxicam is
extremely irritating to the
stomache lining, more so than other nsaids. I think the
frequency of g.i. bleeds is
higher with this drug than its counter parts. Mobic (meloxicam)
is a chemical cousin
that has similar efficasy to Piroxicam, but is safer to use.
Theres a drug called lornoxicam that I think is available in Great
Britain and is stronger than the other oxicams. When and if it hits
the states is another question
