The purpose of the present study was to examine sensitivity to the antinociceptive effects of kappa opioids during chronic treatment with the nonselective opioid antagonist naltrexone. In a warm-water tail-withdrawal procedure, rats were restrained and the latencies to remove their

Kappa opioid agonists were at one time proposed as candidate pharmacotherapies for cocaine addiction, mainly because of their ability to decrease dopamine neurotransmission and attenuate the behavioral effects of cocaine in laboratory animals. Recent studies, however, suggest that kappa agonists

Interactions of opioid agonists, fentanyl and oxymorphone (micro-selective) and spiradoline and enadoline(kappa-selective), were examined for additive, sub-additive, or supra-additive antinociception in the colorectal distension (CRD) assay. Single-dose values (mg/kg, 0.006-0.016 for fentanyl, 0.25-1.26 forspiradoline, etc.) were summed to formulate theoretical

The results of a previous study in rats indicated that spiradoline has pharmacologically selective discriminative effects that are mediated by kappa-opioid receptors. However, the training dose, 3.0 mg/kg, increased response latencies, suggesting that it was relatively high. The current study
