Although bradykinin (BK) antagonists have antinociceptive effects, they have not been evaluated for anti-inflammatory activity. When administered with carrageenan into the rat hindpaw, NPC567 significantly blocked carrageenan-induced hyperalgesia, hyperthermia and edema. In addition, NPC567 did not alter the in vitro release of immunoreactive BK by plasma kallikrein. These results indicate that the antinociceptive activity of NPC567, a BK antagonist, may be related to its overall anti-inflammatory activity and that is mechanism of action does not include inhibition of plasma kallikrein.
