BACKGROUND: In comparison with cutaneous pain, the role of alpha(2)-adrenoceptor (alpha(2)-AR) agonists in visceral pain has not been extensively examined. We aimed to characterize the antinociceptive effect of IV dexmedetomidine on visceral pain in rats and to determine whether antinociception thus produced is mediated by opioid receptors.
