The non-peptide NK1 receptor antagonist, (+/-)-CP-96,345, produces antinociceptive and anti-oedema effects in the rat.
The non-peptide NK1 receptor antagonist, (+/-)-CP-96,345, has been evaluated for antinociceptive activity in two well-characterized inflammatory pain models in the rat. (+/-)-CP-96,345 abolished carrageenin-induced mechanical hyperalgesia, significantly reduced carrageenin-induced paw oedema and attenuated the second phase of the formalin response. The results suggest that NK1 receptor activation occurs during the induction of inflammatory pain states in the rat.
