Description: M-5011 is a non-steroidal anti-inflammatory drug and immunomodulator potentially for the treatment of inflammation and pain. M-5011 had an effective antinociceptive activity (ED50 value) of 0.63 mg/kg, being more potent than zaltoprofen (16.80 mg/kg) and tiaprofenic acid (4.78 mg/kg), equipotent to diclofenac sodium (0.68 mg/kg), and less potent than indomethacin (0.21 mg/kg) and ketoprofen (0.28 mg/kg). M-5011 partially inhibits the generalized bone loss accompanying the development of collagen-induced arthritis in rats. M-5011 is a useful NSAID that shows potent antinociceptive effects with low ulcerogenic activities.
