Effects of low (butorphanol, nalbuphine)-, intermediate (buprenorphine)-, and high (morphine, levorphanol)-efficacy mu opioids were examined in F344, Sprague-Dawley (SD), Long-Evans (LE), and Lewis rats using a tail withdrawal and a drug discriminati

In pigeons (Columba livia; N = 5) trained to discriminate the mu (mu) opioid butorphanol from saline, various mu (morphine, fentanyl) but not kappa (kappa; bremazocine, U50,488, U69,593) opioids produced at least 80% drug-appropriate responding. Subs

The purpose of this investigation was to evaluate the discriminative stimulus effects of the mixed-opioid agonist/antagonist dezocine. In pigeons trained to discriminate 1.7 mg/kg dezocine from saline, a series of opioids with activity at the mu opio

The purpose of the present investigation was to examine the discriminative stimulus effects of opioids with activity at mu and kappa opioid receptors, in pigeons trained to discriminate the mu opioid fentanyl, the kappa opioid bremazocine and water i

The discriminative stimulus effects of butorphanol were examined in separate groups of pigeons trained to discriminate either a low (0.1 mg/kg), medium (1.0 mg/kg) or high (5.6 mg/kg) dose of butorphanol from saline. The mu-selective opioid antagonis

Previous investigations indicate that mixed action opioids (i.e., opioids with activity at a combination of opioid receptor sites or a combination of opioid and nonopioid sites) often possess kappa-like stimulus effects in the rat and monkey, but mu-

The stimulus effects of selective, high efficacy mu opioids and mixed action opioids with varying degrees of intrinsic efficacy at the mu receptor were examined in pigeons trained to discriminate between saline and either 0.056 (low) or 0.18 (high) m

The present study examined the effects of morphine, the intermediate efficacy mu opioids (-)-pentazocine, (-)-metazocine, proxorphan, levallorphan, (-)-NANMY (N-allylnormetazocine) and (-)-cyclazocine, and the mu antagonist naloxone 1) in rats respon

A series of mu and kappa opioid agonists with varying degrees of selectivity were evaluated for their agonist and antagonist effects in squirrel monkeys trained to discriminate either the selective mu agonist fentanyl or the selective kappa agonist U
