FLFQPQRF-amide modulates alpha 2-adrenergic antinociception in the rat dorsal horn in vivo

Brain Res. 1991 Oct 25;562(2):327-8. doi: 10.1016/0006-8993(91)90640-h.

Abstract

The interaction between FLFQPQRFamide and alpha 2-adrenergic spinal antinociception was examined in an electrophysiological study in the intact anaesthetised rat. The inhibition of C fibre-evoked neuronal responses by the selective alpha 2-adrenergic agonist dexmedetomidine was significantly reduced by intrathecal FLFQPQRFamide pretreatment. The results suggest a modulatory role of FLFQPQRFamide in spinal alpha 2-adrenergic antinociception.
