“Administration of the combination of two antagonists (CP-96,345 and either APV or CNQX, or APV and CNQX) more markedly inhibited the behavioral responses to capsaicin (10 nmol/rat) than when either antagonist was co-administered with capsaicin.”
“When co-administered intrathecally with the NMDA antagonist, 2-amino-5-phosphonovaleric acid APV , 10 nmol/rat), the capsaicin (10 nmol/rat) -induced behavioral responses were significantly inhibited.”
