L-745,337: a selective inhibitor of cyclooxygenase-2 elicits antinociception but not gastric ulceration in rats.
L-745,337 [5-methanesulphonamido-6-(2,4-difluorothiophenyl)-1-indan one] a selective cyclooxygenase-2 inhibitor reversed hyperalgesia induced by carrageenan in rats without causing gastric ulceration at doses 100 times those causing antinociception. In contrast, piroxicam and indomethacin produced ulcerations at antinociceptive doses. These findings demonstrate that L-745,337 possesses antinociceptive activity but has a reduced liability for gastric ulceration.
