The Antinociceptive Effects of Intravenous Dexmedetomidine in Colorectal Distension-Induced Visceral Pain in Rats: The Role of Opioid Receptors

Abstract

Our data indicate that IV dexmedetomidine exerts pronounced antinociception against CRD-induced visceral pain and suggest that the antinociceptive effect of dexmedotimidine is mediated in part by opioid receptors, but peripheral alpha(2)-ARs are not involved.
