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...

BACKGROUND: Acute postoperative pain control in children is an essential component of postoperative care, particularly in daycare procedures. Giving patients continuous narcotic analgesics can be risky; however, a single dose may be sufficient. METHODS: This study used a prospective, randomized controlled design and was conducted at the Pediatric Surgery Unit, Services Hospital, Lahore. In total, 150 patients who underwent inguinal herniotomy (age range: 1-12 years) were randomly assigned to two groups: group A (nalbuphine) and group B (tramadol)...

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...

Species-specific acid-base and partition equilibrium constants were experimentally determined for the therapeutically important semisynthetic opioid receptor agonist hydromorphone, dihydromorphine, and mixed agonist-antagonist nalorphine and nalbuphine. The acid-base microequilibria were characterized by combining pH-potentiometry and deductive methods using synthesized auxiliary compounds. Independent of the pH, there are approximately 4.8 times as many zwitterionic microspecies than non-charged ones in nalbuphine solutions, while for nalorphine it is the non-charged form that predominates by the same ratio...

Buprenorphine and the mixed agonists/antagonists nalbuphine and pentazocine, formerly classified as µ-opioid (MOP) receptor antagonists, have more recently been shown to be partial to full agonists of the human MOP receptor. These receptors do not necessarily have to be maximally activated for a full physiological response. Partial agonists can also sufficiently stimulate signaling processes leading to a full analgesic response, as shown by the effectiveness of buprenorphine, nalbuphine and pentazocine in animal pain models and in clinical settings where these drugs induce analgesia with full efficacy without a ceiling effect...

BACKGROUND: Opioids are crucial in cancer pain management. We examined the nationwide prescription patterns of opioids in Taiwan cancer patients to find the potential concerns. METHODS: We reviewed the claims database of the National Health Insurance of Taiwan for patients diagnosed with cancer from 2003 to 2011. The use and cost of analgesics were analyzed. Opioids were classified into recommended strong opioids (morphine and transdermal fentanyl), recommended weak opioids (tramadol, buprenorphine, and codeine), and unrecommended opioids (propoxyphene, nalbuphine, and meperidine)...

BACKGROUND: Topical lidocaine has been found to result in overestimation of the severity of laryngomalacia in infants undergoing flexible bronchoscopy under conscious sedation with midazolam and nalbuphine. This effect has never been confirmed and may depend on the level of sedation and the drugs used. We assessed the effect of topical lidocaine on laryngomalacia in infants undergoing flexible bronchoscopy under general anesthesia with propofol. METHODS: Thirteen infants with congenital stridor referred to diagnostic flexible video-bronchoscopy were studied under propofol anesthesia before and 3 minutes after topical lidocaine administration to the larynx at a dose of 3 mg/kg body weight...

Cannabinoid receptor agonists such as delta-9-tetrahydrocannabinol (Δ(9)-THC) enhance some (antinociceptive) but not other (positive reinforcing) effects of mu opioid receptor agonists, suggesting that cannabinoids might be combined with opioids to treat pain without increasing, and possibly decreasing, abuse. The degree to which cannabinoids enhance antinociceptive effects of opioids varies across drugs insofar as Δ(9)-THC and the synthetic cannabinoid receptor agonist CP55940 increase the potency of some mu opioid receptor agonists (e...

OBJECTIVE: Previous studies have suggested that lowering heart rate (HR) by selective β1-blockers improves sepsis-induced cardiac and vascular dysfunction primarily by decreasing proinflammatory pathways. However, the impact of isolated heart rate reduction (HRR) on hemodynamics and inflammatory pathways remains unknown. The present study was designed to assess the effects of HRR by ivabradine, an If channel inhibitor, on cardiovascular function and inflammatory pathways in peritonitis-induced septic shock in rats...
