Receptor theory predicts that fixed-proportion mixtures of a competitive, reversible agonist (e.g. fentanyl) and antagonist (e.g. naltrexone) at a common receptor (e.g. mu opioid receptors; MOR) will result in antagonist proportion-dependent decreases in apparent efficacy of the mixtures and downward shifts in mixture dose-effect functions. The present study tested this hypothesis by evaluating behavioral effects of fixed-proportion fentanyl/naltrexone mixtures in a warm-water tail-withdrawal procedure in rhesus monkeys (n=4)...

Background and Aims: Opioids have been favored as adjuvants to local anesthetics during spinal anesthesia. Nalbuphine, a μ-receptor antagonist and ĸ-receptor agonist, seems to be a suitable adjuvant to local anesthetics. The aim of this study was to compare postoperative analgesia and adverse effects of nalbuphine and fentanyl when used as an adjuvant to hyperbaric bupivacaine during spinal anesthesia. Materials and Methods: Sixty patients belonging to the American Society of Anesthesiologists Physical Status I and II were randomly allocated into two groups of thirty each...

μ-Opioid agonists are clinically effective analgesics, but also produce undesirable effects such as sedation and abuse potential that limit their clinical utility. Glutamatergic systems also modulate nociception and N-methyl D-aspartate (NMDA) receptor antagonists have been proposed as one useful adjunct to enhance the therapeutic effects and/or attenuate the undesirable effects of μ-opioid agonists. Whether NMDA antagonists enhance the antiallodynic effects of μ-agonists in preclinical models of thermal hypersensitivity (i...

Previous studies demonstrated that nalbuphine, medetomidine, and azaperone (NalMed-A) can effectively immobilize adult elk (Cervus elaphus nelsoni), and be antagonized using naltrexone and atipamezole, with or without tolazoline. To assess duration of tissue residues for this immobilization package, we immobilized 14 captive adult elk with NalMed-A, then euthanized animals and collected tissues 0, 3, 6, 14, 21, or 28 d later. Except for two animals euthanized immediately, all elk were recovered using naltrexone, atipamezole, and tolazoline...

Mice undergo a variety of procedures that necessitate the use of analgesic agents. Opioids are often essential to successful pain management plans, but most are controlled substances, and their use requires appropriate federal and state registrations. Nalbuphine is a potentially effective opioid analgesic for mice that is not currently classified as a controlled substance. This compound has received little attention as an analgesic for mice, and standard dosage regimens have not been developed. Here we compared the pharmacokinetic profiles of 10 mg/kg nalbuphine in male C57BL/6 mice subcutaneous or intraperitoneal administration...

INTRODUCTION: Intrathecal opioids when added to local anaesthetics decrease their dosage and provide haemodynamic stability. Nalbuphine is an agonist-antagonist and acts on kappa receptors providing analgesia. AIM: The study aims to compare the analgesic efficacy of fentanyl with that of two doses of nalbuphine when used with injection bupivacaine heavy in spinal anaesthesia. MATERIALS AND METHODS: A randomised, double blinded, prospective study on 90 patients of ASA I and II undergoing lower limb orthopaedic surgery under subarachnoid block was done...

Nalbuphine is a semi-synthetic opioid indicated for the relief of moderate to severe pain. Its short half-life requires frequent injections in clinical practice, resulting in a greater incidence of adverse events. A prodrug of nalbuphine has been developed, dinalbuphine sebacate (DNS), dissolved in a simple oil-based injectable formulation, which could deliver and maintain an effective blood level of nalbuphine. An open-label, prospective, two-period study was performed in healthy volunteers to verify the extended blood concentration profile of nalbuphine...

PURPOSE: Subcutaneous implantable cardioverter defibrillator (S-ICD) is an alternative to transvenous ICD to prevent sudden cardiac death. Subcutaneous ICD implantation frequently requires general anesthesia because of procedure nociceptive steps during creation of a large device pocket and lead tunneling. This study aims to determine if a strategy of operator-guided controlled sedation with midazolam and analgesia with nalbuphine is effective in alleviating pain during S-ICD implantation...

BACKGROUND: Sepsis research relies on animal models to investigate the mechanisms of the dysregulated host response to infection. Animal welfare concerns request the use of potent analgesics for the Refinement of existing sepsis models, according to the 3Rs principle. Nevertheless, adequate analgesia is often missing, partly because the effects of analgesics in this particular condition are unknown. We evaluated the use of nalbuphine, an opioid with kappa agonistic and mu antagonistic effects, in rats with and without experimental sepsis...

We evaluated a combination of nalbuphine, medetomidine, and azaperone (NalMed-A) in 12 American bison ( Bison bison ) during 13 sedation handling events. The mean (SE) dosage was 0.4 (0.02) mg/kg nalbuphine, 0.08 (0.003) mg/kg medetomidine, and 0.08 (0.003) mg/kg azaperone contained in an average delivery volume of 0.8 mL/100 kg. Two animals required a supplemental dose for safe handling (additive dose used in calculating means) and a third animal was not adequately sedated despite a supplemental dose. Bison immobilized with NalMed-A showed good sedation in 12 of 13 handling attempts...
