Abstract

Naloxone can enhance the antinociceptive/analgesic effects of buprenorphine in humans and rats. The antinociceptive effects of a patented 15:1 buprenorphine:naloxone combination was investigated in cats using a thermal and mechanical nociceptive model. Twelve cats received buprenorphine 10 mu g/kg, naloxone 0.67 mu g/kg or a buprenorphine-naloxone combination intramuscularly in a randomised cross over study. Using thermal and mechanical analgesiometry validated in the cat, pre-treatment baselines were measured. Following test drug administration, thresholds were studied for the next 24 h.

Naloxone did not enhance the thermal antinociceptive effect of buprenorphine. The results from this study are in agreement with previously published work showing that naloxone antagonises the effects of clinically analgesic doses of buprenorphine. Mechanical nociceptive thresholds were not affected by buprenorphine. (C) 2011 Elsevier Ltd. All rights reserved.
