S. Boyce et al., L-745,337 - A SELECTIVE INHIBITOR OF CYCLOOXYGENASE-2 ELICITS ANTINOCICEPTION BUT NOT GASTRIC-ULCERATION IN RATS, Neuropharmacology, 33(12), 1994, pp. 1609-1611
L-745,337 ulphonamido-6-(2,4-difluorothiophenyl)-1-indanone] a selecti
ve cycleoxygenase-2 inhibitor reversed hyperalgesia induced by carrage
enan in rats without causing gastric ulceration at doses 100 times tho
se causing antinociception. In contrast, piroxicam and indomethacin pr
oduced ulcerations at antinociceptive doses. These findings demonstrat
e that L-745,337 possesses antinociceptive activity but has a reduced
liability for gastric ulceration.
