Extracellular single unit recordings were made from dorsal horn nociceptive neurons of intact, urethane-anesthetized rats during controlled electrical stimulation of the hind paw. Neither local superfusion of cholecystokinin octapeptide (CCK; 6.4 pmol to 20 nmol) nor the CCK antagonist lorglumide (LGM; 145 fmol to 145 pmol) significantly altered A- or C-fiber evoked firing or spontaneous activity. Pretreatment with CCK, however, significantly attenuated, whereas LGM enhanced, morphine-induced inhibition of C-evoked firing. These findings provide further evidence that CCK functions as a selective antagonist of opioid-induced analgesia.
