Abstract
BACKGROUND Cancer pain significantly impacts individuals' quality of life, with opioids being employed as the primary means for pain relief. Nevertheless, concerns persist regarding the adverse reactions and effectiveness of opioids such as morphine. Hydromorphone, recognized as a potent opioid, is a viable alternative for managing cancer-related pain. The goal of this systematic review and meta-analysis was to determine the effectiveness and safety characteristics of hydromorphone in comparison to other opioids, as well as different methods of administering this medication within the scope of cancer pain treatment. METHODS The PubMed, Embase, Cochrane Library, Scopus, and Web of Science databases were searched on December 25th, 2023. Following the PRISMA guidelines, a systematic investigation of databases was carried out, and suitable studies were chosen according to predetermined criteria (PICO framework). The meta-analyses were performed using a random-effects model. RESULTS This review included 18 RCTs with 2271 patients who compared hydromorphone with morphine, oxycodone, or fentanyl, as well as other types of hydromorphone. Hydromorphone demonstrated efficacy similar to that of morphine and oxycodone in reducing cancer pain intensity, decreasing additional analgesic consumption, and improving quality of life. However, morphine showed slight superiority over hydromorphone in reducing breakthrough pain. Adverse events were comparable between hydromorphone and morphine or oxycodone. Patient-controlled and clinician-controlled hydromorphone administration routes yielded similar outcomes. CONCLUSIONS The outcomes of this study substantiate the efficacy of hydromorphone in the management of cancer-related pain, demonstrating similar levels of effectiveness and safety as morphine and oxycodone. These findings are consistent with prior comprehensive analyses, suggesting that hydromorphone is a feasible choice for alleviating cancer-associated pain. Additional investigations are warranted to determine its efficacy in distinct patient cohorts and for different modes of administration. TRIAL REGISTRATION Prospero registration ID: CRD42024517513.

Abstract
Over 50 million Americans endure chronic pain where many do not receive adequate treatment and self-medicate to manage their pain by taking substances like opioids and cannabis. Research has shown high comorbidity between chronic pain and substance use disorders (SUD) and these disorders share many common neurobiological underpinnings, including hypodopaminergic transmission. Drugs commonly used for self-medication such as opioids and cannabis relieve emotional, bothersome components of pain as well as negative emotional affect that perpetuates misuse and increases the risk of progressing towards drug abuse. However, the causal effect between chronic pain and the development of SUDs has not been clearly established. In this review, we discuss evidence that affirms the proposition that chronic pain is a risk factor for the development of opioid and cannabis use disorders by outlining the clinical evidence and detailing neurobiological mechanisms that link pain and drug misuse. Central to the link between chronic pain and opioid and cannabis misuse is hypodopaminergic transmission and the modulation of dopamine signaling in the mesolimbic pathway by opioids and cannabis. Moreover, we discuss the role of kappa opioid receptor activation and neuroinflammation in the context of dopamine transmission, their contribution to opioid and cannabis withdrawal, along with potential new treatments.

Abstract
Objective To evaluate the efficacy and safety of patient-controlled analgesia (PCA) with hydromorphone as perioperative analgesia during uterine artery embolization (UAE) via the right radial artery. Patients and methods A total of 33 patients with uterine fibroids, who underwent UAE at the authors' hospital between June 2021 and March 2022, were selected. Hydromorphone (10 mg) was dispensed into a 100 ml PCA pump with normal saline. Pump administration was initiated 15 min before the start of the procedure, and the intraoperative dose was adjusted according to patient pain level. A numerical rating scale was used to evaluate pain immediately after embolization, 5 min after embolization, at the end of the procedure, and 6, 12, 24, 48, and 72 h after the procedure. Side effects were also observed. Results Thirty-three patients underwent uterine artery embolization via the right radial artery. Patient pain was well controlled at all time points surveyed, and patients reported satisfaction with analgesia. The median length of hospital stay was 5 days. There were 7 cases of adverse reactions, but no serious side effects were observed. Conclusion Patients reported positive experiences with arterial embolization of uterine fibroids via the right radial artery. Hydromorphone PCA effectively controlled pain. The PCA pump is easy to operate, has a low incidence of adverse reactions, and offers economic benefits at the patient and institutional levels.

Genome-Wide Association Study Identifies Candidate Loci Associated with Opioid Analgesic Requirements in the Treatment of Cancer Pain. Cancers (Basel) 2022; 14:cancers14194692. [PMID: 36230616 PMCID: PMC9564079 DOI: 10.3390/cancers14194692] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 09/20/2022] [Accepted: 09/21/2022] [Indexed: 11/29/2022] Open
Abstract
Considerable individual differences have been widely observed in the sensitivity to opioids. We conducted a genome-wide association study (GWAS) in patients with cancer pain to identify potential candidate single-nucleotide polymorphisms (SNPs) that contribute to individual differences in opioid analgesic requirements in pain treatment by utilizing whole-genome genotyping arrays with more than 650,000 markers. The subjects in the GWAS were 428 patients who provided written informed consent and underwent treatment for pain with opioid analgesics in a palliative care unit at Higashi-Sapporo Hospital. The GWAS showed two intronic SNPs, rs1283671 and rs1283720, in the ANGPT1 gene that encodes a secreted glycoprotein that belongs to the angiopoietin family. These two SNPs were strongly associated with average daily opioid requirements for the treatment of pain in both the additive and recessive models (p < 5.0000 × 10−8). Several other SNPs were also significantly associated with the phenotype. In the gene-based analysis, the association was significant for the SLC2A14 gene in the additive model. These results indicate that these SNPs could serve as markers that predict the efficacy of opioid analgesics in cancer pain treatment. Our findings may provide valuable information for achieving satisfactory pain control and open new avenues for personalized pain treatment.

Safety and efficacy of intravenous hydromorphone patient-controlled analgesia versus intramuscular pethidine in acute pancreatitis: An open-label, randomized controlled trial. Front Pharmacol 2022; 13:962671.

Abstract
Background: Hydromorphone patient-controlled analgesia (PCA) provides satisfactory postoperative pain therapy, but its effect has not been assessed in acute pancreatitis (AP).Aim: To assess the safety and efficacy of intravenous hydromorphone PCA for pain relief in AP.Methods: This open-label trial included AP patients admitted within 72 h of symptom onset, aged 18–70 years old, and with Visual Analog Scale (VAS) for pain intensity ≥5. They were randomized to receive intravenous hydromorphone PCA (0.05 mg/h with 0.2 mg on-demand) or intramuscular pethidine (50 mg as required) for three consecutive days. Intramuscular dezocine (5 mg on demand) was the rescue analgesia. The primary outcome was the change of VAS score recorded every 4 h for 3 days. Interim analysis was conducted by an Independent Data and Safety Monitoring Committee (IDSMC).Results: From 26 July 2019 to 15 January 2020, 77 patients were eligible for the intention-to-treat analysis in the interim analysis (39 in the hydromorphone group and 38 in the pethidine group). Baseline parameters were comparable between groups. No difference in VAS between the two groups was found. Hydromorphone PCA was associated with higher moderately severe to severe cases (82.1% vs. 55.3%, p = 0.011), acute peripancreatic fluid collections (53.9% vs. 28.9%, p = 0.027), more cumulative opioid consumption (median 46.7 vs. 5 mg, p < 0.001), higher analgesia costs (median 85.5 vs. 0.5 $, p < 0.001) and hospitalization costs (median 3,778 vs. 2,273 $, p = 0.007), and more adverse events (20.5% vs. 2.6%, p = 0.087). The per-protocol analysis did not change the results. Although a sample size of 122 patients was planned, the IDSMC halted further recruitment as disease worsening or worse clinical outcomes between the groups in the interim analysis.Conclusion: Hydromorphone PCA was not superior to pethidine in relieving pain in AP patients and might have worse clinical outcomes. Therefore, its use is not recommended.Clinical Trial Registration: Chictr.org.cn. ChiCTR1900025971

Abstract
BACKGROUND This is an update of the original Cochrane Review first published in Issue 10, 2016. For people with advanced cancer, the prevalence of pain can be as high as 90%. Cancer pain is a distressing symptom that tends to worsen as the disease progresses. Evidence suggests that opioid pharmacotherapy is the most effective of these therapies. Hydromorphone appears to be an alternative opioid analgesic which may help relieve these symptoms. OBJECTIVES To determine the analgesic efficacy of hydromorphone in relieving cancer pain, as well as the incidence and severity of any adverse events. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase and clinical trials registers in November 2020. We applied no language, document type or publication status limitations to the search. SELECTION CRITERIA We included randomised controlled trials (RCTs) that compared hydromorphone with placebo, an alternative opioid or another active control, for cancer pain in adults and children. Primary outcomes were participant-reported pain intensity and pain relief; secondary outcomes were specific adverse events, serious adverse events, quality of life, leaving the study early and death. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data. We calculated risk ratio (RR) and 95% confidence intervals (CI) for binary outcomes on an intention-to-treat (ITT) basis. We estimated mean difference (MD) between groups and 95% CI for continuous data. We used a random-effects model and assessed risk of bias for all included studies. We assessed the evidence using GRADE and created three summary of findings tables. MAIN RESULTS With four new identified studies, the review includes a total of eight studies (1283 participants, with data for 1181 participants available for analysis), which compared hydromorphone with oxycodone (four studies), morphine (three studies) or fentanyl (one study). All studies included adults with cancer pain, mean age ranged around 53 to 59 years and the proportion of men ranged from 42% to 67.4%. We judged all the studies at high risk of bias overall because they had at least one domain with high risk of bias. We found no studies including children. We did not complete a meta-analysis for the primary outcome of pain intensity due to skewed data and different comparators investigated across the studies (oxycodone, morphine and fentanyl). Comparison 1: hydromorphone compared with placebo We identified no studies comparing hydromorphone with placebo. Comparison 2: hydromorphone compared with oxycodone Participant-reported pain intensity We found no clear evidence of a difference in pain intensity (measured using a visual analogue scale (VAS)) in people treated with hydromorphone compared with those treated with oxycodone, but the evidence is very uncertain (3 RCTs, 381 participants, very low-certainty evidence). Participant-reported pain relief We found no studies reporting participant-reported pain relief. Specific adverse events We found no clear evidence of a difference in nausea (RR 1.13 95% CI 0.74 to 1.73; 3 RCTs, 622 participants), vomiting (RR 1.18, 95% CI 0.72 to 1.94; 3 RCTs, 622 participants), dizziness (RR 0.91, 95% CI 0.58 to 1.44; 2 RCTs, 441 participants) and constipation (RR 0.92, 95% CI 0.72 to 1.19; 622 participants) (all very low-certainty evidence) in people treated with hydromorphone compared with those treated with oxycodone, but the evidence is very uncertain. Quality of life We found no studies reporting quality of life. Comparison 3: hydromorphone compared with morphine Participant-reported pain intensity We found no clear evidence of a difference in pain intensity (measured using the Brief Pain Inventory (BPI) or VAS)) in people treated with hydromorphone compared with those treated with morphine, but the evidence is very uncertain (2 RCTs, 433 participants; very low-certainty evidence). Participant-reported pain relief We found no clear evidence of a difference in the number of clinically improved participants, defined by 50% or greater pain relief rate, in the hydromorphone group compared with the morphine group, but the evidence is very uncertain (RR 0.99, 95% CI 0.84 to 1.18; 1 RCT, 233 participants; very low-certainty evidence). Specific adverse events At 24 days of treatment, morphine may reduce constipation compared with hydromorphone, but the evidence is very uncertain (RR 1.56, 95% CI 1.12 to 2.17; 1 RCT, 200 participants; very low-certainty evidence). We found no clear evidence of a difference in nausea (RR 0.94, 95% CI 0.66 to 1.30; 1 RCT, 200 participants), vomiting (RR 0.87, 95% CI 0.58 to 1.31; 1 RCT, 200 participants) and dizziness (RR 1.15, 95% CI 0.71 to 1.88; 1 RCT, 200 participants) (all very low-certainty evidence) in people treated with hydromorphone compared with those treated with morphine, but the evidence is very uncertain. Quality of life We found no studies reporting quality of life. Comparison 4: hydromorphone compared with fentanyl Participant-reported pain intensity We found no clear evidence of a difference in pain intensity (measured by numerical rating scale (NRS)) at 60 minutes in people treated with hydromorphone compared with those treated with fentanyl, but the evidence is very uncertain (1 RCT, 82 participants; very low-certainty evidence). Participant-reported pain relief We found no studies reporting participant-reported pain relief. Specific adverse events We found no studies reporting specific adverse events. Quality of life We found no studies reporting quality of life. AUTHORS' CONCLUSIONS The evidence of the benefits and harms of hydromorphone compared with other analgesics is very uncertain. The studies reported some adverse events, such as nausea, vomiting, dizziness and constipation, but generally there was no clear evidence of a difference between hydromorphone and morphine, oxycodone or fentanyl for this outcome. There is insufficient evidence to support or refute the use of hydromorphone for cancer pain in comparison with other analgesics on the reported outcomes. Further research with larger sample sizes and more comprehensive outcome data collection is required.

Abstract
OBJECTIVE To evaluate the pharmacokinetics of hydromorphone hydrochloride after IM and IV administration to orange-winged Amazon parrots (Amazona amazonica). ANIMALS 8 orange-winged Amazon parrots (4 males and 4 females). PROCEDURES Hydromorphone (1 mg/kg) was administered once IM. Blood samples were collected 5 minutes and 0.5, 1.5, 2, 3, 6, and 9 hours after drug administration. Plasma hydromorphone concentrations were determined with liquid chromatography-tandem mass spectrometry, and pharmacokinetic parameters were calculated with a compartmental model. The experiment was repeated 1 month later with the same dose of hydromorphone administered IV. RESULTS Plasma hydromorphone concentrations were > 1 ng/mL for 6 hours in 8 of 8 and 6 of 7 parrots after IM and IV injection, respectively. After IM administration, mean bioavailability was 97.6%, and mean maximum plasma concentration was 179.1 ng/mL 17 minutes after injection. Mean volume of distribution and plasma drug clearance were 4.24 L/kg and 64.2 mL/min/kg, respectively, after IV administration. Mean elimination half-lives were 1.74 and 1.45 hours after IM and IV administration, respectively. CONCLUSIONS AND CLINICAL RELEVANCE Hydromorphone hydrochloride had high bioavailability and rapid elimination after IM administration, with rapid plasma clearance and a large volume of distribution after IV administration in orange-winged Amazon parrots. Drug elimination half-lives were short. Further pharmacokinetic studies of hydromorphone and its metabolites, including investigation of multiple doses, different routes of administration, and sustained-release formulations, are recommended.

Abstract
OBJECTIVE To evaluate the thermal antinociceptive effects of hydromorphone hydrochloride after IM administration to orange-winged Amazon parrots (Amazona amazonica). ANIMALS 8 healthy adult parrots (4 males and 4 females). PROCEDURES In a randomized crossover study, each bird received hydromorphone (0.1, 1, and 2 mg/kg) and saline (0.9% NaCl) solution (1 mL/kg; control) IM, with a 7-day interval between treatments. Each bird was assigned an agitation-sedation score, and the thermal foot withdrawal threshold (TFWT) was measured at predetermined times before and after treatment administration. Adverse effects were also monitored. The TFWT, agitation-sedation score, and proportion of birds that developed adverse effects were compared among treatments over time. RESULTS Compared with the mean TFWT for the control treatment, the mean TFWT was significantly increased at 0.5, 1.5, and 3 hours and 1.5, 3, and 6 hours after administration of the 1- and 2-mg/kg hydromorphone doses, respectively. Significant agitation was observed at 0.5, 1.5, and 3 hours after administration of the 1 - and 2-mg/kg hydromorphone doses. Other adverse effects observed after administration of the 1- and 2-mg/kg doses included miosis, ataxia, and nausea-like behavior (opening the beak and moving the tongue back and forth). CONCLUSIONS AND CLINICAL RELEVANCE Although the 1- and 2-mg/kg hydromorphone doses appeared to have antinociceptive effects, they also caused agitation, signs of nausea, and ataxia. Further research is necessary to evaluate administration of lower doses of hydromorphone and other types of stimulation to better elucidate the analgesic and adverse effects of the drug in psittacine species.

Pooled Dosing and Efficacy Analysis of the Sufentanil Sublingual Tablet 30 mcg Across Demographic Subgroups for the Management of Moderate-to-Severe Acute Pain. J Perianesth Nurs 2019; 35:22-28. [PMID: 31732448 DOI: 10.1016/j.jopan.2019.08.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Revised: 08/12/2019] [Accepted: 08/25/2019] [Indexed: 11/23/2022]
Abstract
PURPOSE To aid nurses in dosing sufentanil sublingual tablet (SST) 30 mcg administered via a single-dose applicator, dosing requirements and efficacy of SST 30 mcg were analyzed across age, sex, race, and body mass index subgroups. DESIGN Patient characteristics were pooled from three postoperative studies (two placebo-controlled and one open-label) and one open-label emergency department study. Drug dosing and efficacy data were pooled from the postoperative studies. METHODS Efficacy was assessed through summed pain intensity difference to baseline during 12 hours across subgroups. FINDINGS Mean (standard deviation) drug doses administered from 0 to 12 hours was 3.9 (2.0) for SST 30 mcg and was less frequent for older (≥65 years) versus younger patients. The summed pain intensity difference to baseline during 12 hours was superior with SST 30 mcg versus placebo across all subgroups. CONCLUSIONS SST 30 mcg is a sublingual opioid analgesic with efficacy across demographic subgroups.

Abstract
We know little about the safety or efficacy of pharmacological medicines for children and adolescents with chronic pain, despite their common use. Our aim was to conduct an overview review of systematic reviews of pharmacological interventions that purport to reduce pain in children with chronic noncancer pain (CNCP) or chronic cancer-related pain (CCRP). We searched the Cochrane Database of Systematic Reviews, Medline, EMBASE, and DARE for systematic reviews from inception to March 2018. We conducted reference and citation searches of included reviews. We included children (0-18 years of age) with CNCP or CCRP. We extracted the review characteristics and primary outcomes of ≥30% participant-reported pain relief and patient global impression of change. We sifted 704 abstracts and included 23 systematic reviews investigating children with CNCP or CCRP. Seven of those 23 reviews included 6 trials that involved children with CNCP. There were no randomised controlled trials in reviews relating to reducing pain in CCRP. We were unable to combine data in a meta-analysis. Overall, the quality of evidence was very low, and we have very little confidence in the effect estimates. The state of evidence of randomized controlled trials in this field is poor; we have no evidence from randomised controlled trials for pharmacological interventions in children with cancer-related pain, yet cannot deny individual children access to potential pain relief.

Abstract
OBJECTIVE To evaluate the thermal antinociceptive effects and pharmacokinetics of hydromorphone hydrochloride after IM administration to cockatiels (Nymphicus hollandicus). ANIMALS 16 healthy adult cockatiels. PROCEDURES During the first of 2 study phases, each cockatiel received each of 4 treatments (hydromorphone at doses of 0.1, 0.3, and 0.6 mg/kg and saline [0.9% NaCl] solution [0.33 mL/kg; control], IM), with a 14-day interval between treatments. For each bird, foot withdrawal to a thermal stimulus was determined following assignment of an agitation-sedation score at predetermined times before and for 6 hours after each treatment. During the second phase, a subset of 12 birds received hydromorphone (0.6 mg/kg, IM), and blood samples were collected at predetermined times for 9 hours after drug administration. Plasma hydromorphone concentration was determined by liquid chromatography-mass spectrometry. Noncompartmental analysis of sparse data was used to calculate pharmacokinetic parameters. RESULTS Thermal withdrawal response did not differ among the 4 treatment groups at any time. Agitation-sedation scores following administration of the 0.3-and 0.6-mg/kg doses of hydromorphone differed significantly from those treated with saline solution and suggested the drug had a sedative effect. Plasma hydromorphone concentrations were > 1 ng/mL for 3 to 6 hours after drug administration in all birds. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that IM administration of hydromorphone at the evaluated doses did not increase the thermal withdrawal threshold of cockatiels despite plasma drug concentrations considered therapeutic for other species. Further research is necessary to evaluate the analgesic effects of hydromorphone in cockatiels.

Abstract
CONTEXT The aim of this review is to recognizing different methods of analgesia for emergency medicine physicians (EMPs) allows them to have various pain relief methods to reduce pain and to be able to use it according to the patient's condition and to improve the quality of their services. EVIDENCE ACQUISITION In this review article, the search engines and scientific databases of Google Scholar, Science Direct, PubMed, Medline, Scopus, and Cochrane for emergency pain management methods were reviewed. Among the findings, high quality articles were eventually selected from 2000 to 2018, and after reviewing them, we have conducted a comprehensive comparison of the usual methods of pain control in the emergency department (ED). RESULTS For better understanding, the results are reported in to separate subheadings including "Parenteral agents" and "Regional blocks". Non-opioids analgesics such as nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen are commonly used in the treatment of acute pain. However, the relief of acute moderate to severe pain usually requires opioid agents. Considering the side effects of systemic drugs and the restrictions on the use of analgesics, especially opioids, regional blocks of pain as part of a multimodal analgesic strategy can be helpful. CONCLUSION This study was designed to investigate and identify the disadvantages and advantages of using each drug to be able to make the right choices in different clinical situations for patients while paying attention to the limitations of the use of these analgesic drugs.

Abstract
BACKGROUND In Japan, there are limited options for switching opioid analgesics. Hydromorphone is an opioid analgesic that is routinely used instead of morphine for cancer pain; however, it is not yet available in Japan. The aim of this study was to assess the efficacy and safety of hydromorphone (DS-7113b) extended-release tablets in opioid-naïve patients with cancer pain not relieved by non-opioid analgesics. SUBJECTS AND METHODS This was a multicenter, randomized, double-blind, parallel-group trial. A double-dummy method was used for blinding. Each randomized subject received either hydromorphone extended-release tablets plus placebo oxycodone hydrochloride extended-release tablets 4 mg/day (n=88) or placebo hydromorphone extended-release tablets plus oxycodone hydrochloride extended-release tablets 10 mg/day (n=93) orally for 7 days (once-daily dosing for hydromorphone and twice-daily dosing for oxycodone). The doses were adjusted as necessary. Efficacy was evaluated by change in visual analog scale (VAS) score from baseline to completion of treatment. RESULTS The between-group difference in least squares mean changes in VAS score from baseline to completion or discontinuation of treatment was -0.4 mm (95% CI -5.9 to 5 mm) by analysis of covariance where the baseline VAS score was used as a covariate. The upper limit of the 95% CI was below 10 mm, which was predefined as the noninferiority limit. This verified the noninferiority of hydromorphone tablets relative to oxycodone tablets. The incidence of adverse events was 80.7% (71 of 88) in the hydromorphone group and 83.7% (77 of 93) in the oxycodone group. The most common adverse events were nausea, vomiting, somnolence, diarrhea, and constipation, most of which are commonly observed with opioid analgesics. CONCLUSION The efficacy and safety of hydromorphone extended-release tablets were equivalent to those of the oxycodone extended-release formulation.

Suitability of the DRI Hydrocodone/Hydromorphone Immunoassay in the Clinical Environment at a Lower Cutoff: Validation With LC-MS/MS Analysis. Ther Drug Monit 2016; 38:787-790.

Abstract
BACKGROUND We evaluated the analytical performance of the DRI hydrocodone/hydromorphone assay by comparing semiquantitative values obtained by this assay with values obtained by a liquid chromatography combined with tandem mass spectrometry (LC-MS/MS) method. We also evaluated the possibility of lowering the cutoff of the DRI assay from 300 to 100 ng/mL. METHODS We compared semiquantitative values obtained by the DRI assay in 97 specimens with values obtained by the LC-MS/MS method including 10 specimens containing hydrocodone and/or hydromorphone concentrations between 105.0 and 145.0 ng/mL (determined by LC-MS/MS) to determine the sensitivity at 100 ng/mL. In addition, several opioids at a concentration of 5000 ng/mL were also analyzed by the DRI assay to determine its specificity. RESULTS We observed no false-negative result using the DRI immunoassay in 96 specimens that showed semiquantitative values at 100 ng/mL or higher. However, one specimen containing 110 ng/mL of hydrocodone was false negative with the DRI assay (semiquantitative value 88 ng/mL, below 100 ng/mL cutoff). The semiquantitative values produced by DRI showed poor correlation with values determined by the LC-MS/MS method. The sensitivity of the DRI assay at 100 ng/mL was 90%, and the assay was very specific showing minimal cross-reactivity only with oxycodone and oxymorphone. CONCLUSIONS DRI immunoassay for hydrocodone/hydromorphone is a cost-effective method of screening urine specimens in the clinical environment at a lower cutoff of 100 ng/mL.

Abstract
BACKGROUND Cancer pain is an important and distressing symptom that tends to increase in frequency and intensity as the cancer advances. For people with advanced cancer, the prevalence of pain can be as high as 90%. It has been estimated that 30% to 50% of people with cancer categorise their pain as moderate to severe, with between 75% and 90% of people with cancer experiencing pain that they describe as having a major impact on their daily life. Epidemiological studies suggest that approximately 15% of people with cancer pain fail to experience acceptable pain relief with conventional management. Uncontrolled pain can lead to physical and psychological distress and can, consequently, have a drastic effect on people's quality of life. OBJECTIVES To determine the analgesic efficacy of hydromorphone in relieving cancer pain, as well as the incidence and severity of any adverse events. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase and clinical trials registers up to April 2016. There were no language, document type or publication status limitations applied in the search. SELECTION CRITERIA We included randomised controlled trials (RCTs) that compared hydromorphone with placebo or other active pain medication for cancer pain in both adults and children. The four main outcomes selected have previously been identified as important to people with cancer; pain no worse than mild pain, and the impact of the treatment on consciousness, appetite and thirst. We did not consider physician-, nurse- or carer-reported measures of pain. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data. For binary outcomes, we calculated risk ratio (RR) and its 95% confidence interval (CI), on an intention-to-treat basis. For continuous data, we estimated the mean difference (MD) between groups and its 95% CI. We used a random-effects model and assessed the risk of bias for all included studies. A meta-analysis was not completed on any of the primary outcomes in this review due to the lack of data. We assessed the evidence using GRADE and created two 'Summary of findings' tables. MAIN RESULTS We included four studies (604 adult participants), which compared hydromorphone to oxycodone (two studies) or morphine (two studies). Overall, the included studies were at low or unclear risk of bias, rated unclear due to unknown status of blinding of outcome assessment; we rated three studies at high risk of bias for potential conflict of interest. Data for 504 participants were available for analysis. We collected data on endpoint participant-reported pain intensity measured with a visual analogue scale (VAS) (mean ± standard deviation (SD): hydromorphone 28.86 ± 17.08, n = 19; oxycodone 30.30 ± 25.33, n = 12; scale from 0 to 100 with higher score indicating worse pain), and Brief Pain Inventory (BPI) 24 hours worst pain subscale (mean ± SD: hydromorphone 3.5 ± 2.9, n = 99; morphine 4.3 ± 3.0, n = 101, scale from 0 to 10 with higher score indicating worse pain). The data demonstrated a similar effect between groups with both comparisons. The pain intensity data showed that participants in all four trials achieved no worse than mild pain. There were several adverse events: some were the expected opioid adverse effects such as nausea, constipation and vomiting; others were not typical opioid adverse effects (for example, decreased appetite, dizziness and pyrexia, as shown in Table 1 in the main review), but generally showed no difference between groups. There were three deaths in the morphine group during the trial period, considered to be due to disease progression and unrelated to the drug. Three trials had over 10% dropout, but the reason and proportion of dropout was balanced between groups. The overall quality of evidence was very low mainly due to high risk of bias, imprecision of effect estimates and publication bias. There were no data available for children or for several participant-important outcomes, including participant-reported pain relief and treatment impact on consciousness, appetite or thirst. AUTHORS' CONCLUSIONS This review indicated little difference between hydromorphone and other opioids in terms of analgesic efficacy. Data gathered in this review showed that hydromorphone had a similar effect on participant-reported pain intensity as reported for oxycodone and morphine. Participants generally achieved no worse than mild pain after taking hydromorphone, which is comparable with the other drugs. It produced a consistent analgesic effect through the night and could be considered for use in people with cancer pain experiencing sleep disturbance. However, the overall quality of evidence was very low mainly due to risk of bias, imprecision of effect estimates and publication bias. This review only included four studies with limited sample size and a range of study designs. Data for some important outcomes, such as impact of the treatment on consciousness, appetite or thirst, were not available. Therefore, we were unable to demonstrate superiority or inferiority of hydromorphone in comparison with other analgesics for these outcomes. We recommend that further research with larger sample sizes and more comprehensive outcome data collection is required.

Abstract
PURPOSE This investigation evaluated the efficacy of nalbuphine in treating postoperative opioid-induced pruritus (Pr) in pediatric patients. METHODS After Ethics Board approval, the dual site, tertiary care teaching centre study recruited 212 subjects, age ≥ seven years, who received opioid analgesia postoperatively. A modified, self-report colour analogue scale (CAS) scored pruritus intensity (PrI). Subjects who reported PrI score ≥ 5/10 were randomized to treatment with nalbuphine 50 µg·kg(-1) iv (max 5 mg) or saline placebo. A pruritus intensity difference (PrID) ≥ 50% was considered a positive outcome. RESULTS Of 260 subjects approached, 212 consented and 184 received opioids. Median age was 13 yr (range 7-19) and median weight was 51 kg (range 19.6-134.8 kg). Pruritus intensity ≥ 5/10 occurred in 37 (20.1%) subjects. Intravenous morphine [patient-controlled analgesia (PCA)/continuous infusion] was associated with Pr in 68% of subjects over a wide dose range (9.4-63.2 µg·kg(-1)·hr(-1)). Pruritis occurred in 36% of patients in the PCA group compared to continuous opioid infusion (27%) and epidural administration (27%). Pruritus intensity difference ≥ 50% was achieved in 55.6% of nalbuphine and 57.9% of saline-treated subjects. CONCLUSION This preliminary report suggests that nalbuphine 50 µg·kg(-1) iv is not effective in treating postoperative opioidinduced pruritus in pediatric patients. The modified CAS score and PrID warrant further investigation. OBJECTIF Évaluer l'efficacité de la nalbuphine contre le prurit (Pr) postopératoire induit par les opioïdes chez des patients pédiatriques. MéTHODE: Nous avons recruté 212 sujets de ≥ sept ans qui ont reçu une analgésie opioïde postopératoire. Une échelle analogique de couleur (EAC) modifiée pour l'auto-évaluation a mesuré les scores d'intensité du prurit (IPr). Répartis au hasard, les sujets dont les scores d'IPr étaient ≥ 5/10 ont reçu de la nalbuphine à 50 µg·kg(-1) iv (5 mg maximal) ou un placebo salin. Une différence d'intensité de prurit (DIPr) ≥50% était considérée positive. RéSULTATS: Des 260 sujets rencontrés, 212 ont participé à l'étude et 184 ont reçu des opioïdes. L'âge moyen a été de 13 ans (7-19) et le poids moyen de 51 kg (19,6-134,8 kg). Un prurit ≥ 5/10 a été noté chez 37 (20,1 %) des sujets. De la morphine intraveineuse [en analgésie auto-contrôlée (AAC) ou en perfusion continue] a été associée à du Pr chez 68 % des sujets pour un grand éventail de doses (9,4-63,2 µg·kg(-1)·h(-1)). Le prurit s'est manifesté chez 36 % des patients avec l'AAC comparée à la perfusion d'opioïde continue (27 %) et à l'administration péridurale (27 %). Une différence d'intensité du prurit ≥ 50 % a été atteinte chez 55,6 % des sujets qui recevaient la nalbuphine et 57,9 % de ceux qui avaient le placebo. CONCLUSION La nalbuphine iv à 50 µg·kg(-1) n'est pas efficace pour traiter le prurit postopératoire induit par les opioïdes chez des patients pédiatriques. Le score modifié à l'EAC et la DIPr devront être étudiés plus à fond.

Abstract
Acute pain management is improving steadily over the past few years, but training and professional education are still lacking in many professions. Untreated or undertreated acute pain could have detrimental effects on the patient in terms of comfort and recovery from trauma or surgery. Acute undertreated pain can decrease a patient's vascular perfusion, increase oxygen demand, suppress the immune system, and possibly risk increased incidence of venous thrombosis. Although acute postoperative pain needs to be managed aggressively, patients are most vulnerable during this period for developing adverse effects, and therefore, patient assessment and careful drug therapy evaluation are necessary processes in therapeutic planning. Acute pain management requires careful and thorough initial assessment and follow-up reassessment in addition to frequent dosage adjustments, and managing analgesic induced side effects. Analgesic selection and dosing must be based on the patient's past and recent analgesic exposure. There is no single acute pain management regimen that is suitable for all patients. Analgesics must be tailored to the individual patient.

Abstract
Introduction:Despite the growing recognition for analgesic needs in post-craniotomy patients, this remains a poorly studied area in neurological surgery. The class and regimen of analgesia that is most suitable for these patients remains controversial. The objective of this study is to examine the current beliefs and practices of Canadian neurosurgeons when managing post-craniotomy pain.Methods:A survey was sent to all practicing Canadian neurosurgeons to examine the following aspects of analgesia in craniotomy patients: type of analgesics used, common side effects encountered, satisfaction with current regimen and the rationale for their practice.Results:Of 156 potential respondents, 103 neurosurgeons (66%) completed the survey. Codeine (59%) was the most prescribed firstline analgesic followed by morphine (38%). The use of a second-line opioid was significantly higher among codeine prescribers compared to morphine, 53% compared to 28% (p < 0.001). Nausea, constipation and neurologic depression were reported as common side effects by 76%, 66% and 27% of respondents respectively. Of the respondents, 90% reported a high level of satisfaction with their current choice of analgesia; nonetheless, they predominantly described their practice as personal preference or protocol driven rather than evidence-based.Conclusions:Codeine - a weak opioid - is the most common first-line analgesic prescribed to craniotomy patients. This practice is associated with substantially increased reliance on potent opioids for rescue analgesia. Whether novel regimens can provide optimal pain control while minimizing neurologic and gastrointestinal side effects remains to be addressed by future trials.

Abstract
Objective Patient controlled analgesia (PCA) is commonly used to provide analgesia following surgical procedures in the pediatric population. Morphine and hydromorphone remain the most commonly used opioids for PCA. Although both are effective, adverse effects may occur. When these adverse effects are unremitting or severe, opioid rotation may be required. In this study, we retrospectively evaluated PCA use, the adverse effect profile, and the frequency of opioid rotation. Methods This retrospective study was performed at Nationwide Children’s Hospital (Columbus, OH). The hospital’s electronic registry was queried for PCA use delivering either morphine or hydromorphone from January 1, 2008 to December 31, 2010. Results A total of 514 patients were identified, that met study entry criteria. Of the 514 cases, 298 (56.2%) were initially started on morphine and 225 (43.8%) were initially started on hydromorphone. There were a total of 26 (5.1%) opioid changes in the cohort of 514 patients. Of the 26 switches, 23 of 298 (7.7%) were from morphine to hydromorphone, and 3 of 225 (1.3%) were from hydromorphone to morphine (P=0.0008). Of the 17 morphine-to-hydromorphone switches with adverse effects, pruritus (64.7%), and inadequate pain control (47.1%) were the most common side effects. The most common side effect resulting in a hydromorphone-to-morphine switch was nausea (66.7%). Conclusion PCA switches from morphine-to-hydromorphone (88.5%) were more common than vice-versa (11.5%). The most common reasons for morphine-to-hydromorphone switch were pruritus and inadequate pain control. These data suggest that a prospective study is necessary to determine the side effect differences between morphine and hydromorphone in pediatric PCA.

Abstract
Conventional measures such as maximum plasma concentration (Cmax) and area under the concentration versus time curve (AUC) may be insufficient to fully describe the pharmacokinetic (PK) profile of extended-release (ER) formulations. A complementary measure, the half-value duration (HVD), corresponds to the period of time during a dosing cycle that plasma concentration is at or above half the value of the maximal concentration (i.e. ≥50% Cmax). The current post-hoc analysis uses data from 2 previously published studies comparing the PK profiles and HVD of OROS hydromorphone ER (16 mg administered once daily) and immediate-release (IR) hydromorphone (4 mg administered every 6 hours), calculating single-dose and steady-state condition values. Bioequivalence was demonstrated between the 2 formulations. Mean steady-state once-daily OROS hydromorphone ER concentrations were elevated for most of the 24-hour dosing period and for significantly longer than with the dose-equivalent IR hydromorphone regimen. The duration of time spent ≥50% Cmax was, on average, 2.7 times longer at steady state for the ER formulation, which also maintained steady-state hydromorphone plasma concentrations, with 65% lower mean degree of fluctuation versus IR hydromorphone. Both formulations appeared to be well tolerated.

Abstract
Purpose To describe the efficacy and safety of hydromorphone extended-release tablets (OROS hydromorphone ER) during dose conversion and titration. Patients and methods A total of 459 opioid-tolerant adults with chronic moderate to severe low back pain participated in an open-label, 2- to 4-week conversion/titration phase of a double-blind, placebo-controlled, randomized withdrawal trial, conducted at 70 centers in the United States. Patients were converted to once-daily OROS hydromorphone ER at 75% of the equianalgesic dose of their prior total daily opioid dose (5:1 conversion ratio), and titrated as frequently as every 3 days to a maximum dose of 64 mg/day. The primary outcome measure was change in pain intensity numeric rating scale; additional assessments included the Patient Global Assessment and the Roland–Morris Disability Questionnaire scores. Safety assessments were performed at each visit and consisted of recording and monitoring all adverse events (AEs) and serious AEs. Results Mean (standard deviation) final daily dose of OROS hydromorphone ER was 37.5 (17.8) mg. Mean (standard error of the mean [SEM]) numeric rating scale scores decreased from 6.6 (0.1) at screening to 4.3 (0.1) at the final titration visit (mean [SEM] change, −2.3 [0.1], representing a 34.8% reduction). Mean (SEM) change in Patient Global Assessment was −0.6 (0.1), and mean change (SEM) in the Roland–Morris Disability Questionnaire was −2.8 (0.3). Patients achieving a stable dose showed greater improvement than patients who discontinued during titration for each of these measures (P < 0.001). Almost 80% of patients achieving a stable dose (213/268) had a ≥30% reduction in pain. Commonly reported AEs were constipation (15.4%), nausea (11.9%), somnolence (8.7%), headache (7.8%), and vomiting (6.5%); 13.0% discontinued from the study due to AEs. Conclusion The majority of opioid-tolerant patients with chronic low back pain were successfully converted to effective doses of OROS hydromorphone ER within 2 to 4 weeks.

Abstract
CONTEXT The efficacy and tolerability of once-daily hydromorphone extended release (ER) (OROS(®) hydromorphone ER, Exalgo(®), Mallinckrodt Brand Pharmaceuticals, Inc., Hazelwood, MO) in patients with chronic cancer and noncancer pain have been reported in previous studies. OBJECTIVES The objective of this analysis was to assess the pooled safety data of OROS hydromorphone ER in opioid-tolerant patients with chronic cancer and noncancer pain. METHODS Safety results were pooled from 11 clinical studies in opioid-tolerant patients: one 12-week, double-blind, placebo-controlled study; three active-controlled studies; and seven uncontrolled studies (durations of three to 52 weeks). Patients were included in this analysis if they took ≥1 dose of study medication. Descriptive statistics were used to analyze baseline and demographic characteristics, supplemental analgesic use, and incidence of adverse events (AEs). RESULTS In total, 1251 opioid-tolerant patients received ≥1 dose of OROS hydromorphone ER. Mean (SD) duration of exposure was 43.1 (67.8) days (range 1-396 days), and mean (SD) daily dose was 43.4 (47.1) mg. Overall, 1081 patients (86.4%) used supplemental rescue analgesics. The overall incidence of AEs was 76.9%. The most frequently reported AEs were nausea (23.2%), constipation (22.4%), vomiting (14.4%), somnolence (12.9%), and headache (12.8%). Treatment-related constipation occurred in 20.5% of patients, nausea in 16.8%, somnolence in 11.8%, vomiting in 8.2%, and headache in 7.0%. Serious adverse events occurred in 13.5% of patients, with the most frequently reported serious adverse events being dehydration, nausea, and vomiting. No treatment-related deaths occurred. CONCLUSION Once-daily OROS hydromorphone ER demonstrated a safety and tolerability profile in opioid-tolerant patients that is consistent with the known safety profiles of opioids.

Abstract
Objective To characterize the steady-state pharmacokinetic profile of hydromorphone extended-release (ER) in patients with chronic pain taking concomitant medications. Methods This open-label repeat-dose study enrolled 22 patients (mean age, 51.4 years; 81.8% female). All patients were receiving at least one concomitant medication; 86.4% were receiving at least two concomitant medications and 81.8% were receiving at least three. Patients receiving a stable dose of an opioid were converted to hydromorphone ER at a 5:1 ratio (morphine equivalent:hydromorphone). The dose was titrated to adequate analgesia over 3–14 days and stabilized between 8–48 mg. Oral morphine immediate-release was permitted for breakthrough pain. Area under the concentration–time curve from 0–24 hours (AUC0–24), maximum plasma concentration (Cmax), trough plasma concentration (Cmin), average plasma concentration (Cavg), and degree of fluctuation (100 × [(Cmax − Cmin) ÷ Cavg]) were calculated based on data from 14 patients. Results Dose-normalized to 16 mg, mean pharmacokinetic parameter values were: AUC0–24, 41.1 ng · h/mL; Cmax, 2.6 ng/mL; Cmin, 1.1 ng/mL; Cavg, 1.7 ng/mL; and the degree of fluctuation was 99.6%. The pharmacokinetic profile of hydromorphone ER was linear and consistent with dose proportionality. Mean pain intensity difference scores showed statistically significant improvement from 2–21 hours after dosing. Sixteen (72.7%) patients reported at least one adverse event (AE). The most common were constipation (31.8%), headache (22.7%), and vomiting (13.6%). One patient discontinued treatment due to vomiting. No deaths, serious AEs, or unexpected AEs occurred. Conclusion These findings replicate and extend the steady-state pharmacokinetic profile of hydromorphone ER, previously characterized in healthy volunteers, to a population of chronic pain patients taking numerous concomitant medications.

Abstract
OBJECTIVE Opioids are recommended for patients with moderate to severe pain due to osteoarthritis (OA), who do not receive adequate analgesia from nonopioid treatment. The objective of this study was to evaluate the efficacy and safety of OROS hydromorphone extended-release (ER) compared with placebo in patients with moderate to severe pain associated with OA. METHODS This was a randomized, placebo-controlled, double-blind, fixed-dose study. Patients received placebo or fixed-dose OROS hydromorphone ER (8 or 16 mg). The primary efficacy measure was pain intensity score (11-point Numeric Rating Scale) at Maintenance Week 12, analyzed with baseline observation carried forward (BOCF) imputation for missing data. RESULTS This study did not meet the primary efficacy measure using the BOCF imputation. Study discontinuation was high (52%). When analyzed using last observation carried forward (LOCF) imputation, the prespecified alternate method, OROS hydromorphone ER 16 mg provided significantly better analgesia than placebo (P = 0.0009). Treatment was associated with significant improvements in patient global assessment (P = 0.01), the overall Western Ontario and McMaster Osteoarthritis Index (WOMAC) (P = 0.0003), and its subscales: pain (P = 0.0001), stiffness (P = 0.0023), and physical function (P = 0.0006). Gastrointestinal adverse events, such as constipation and nausea, were common among patients receiving OROS hydromorphone ER. CONCLUSIONS OROS hydromorphone ER failed to achieve statistical significance for the primary endpoint using the prespecified imputation method (BOCF), likely due to the high discontinuation rate associated with the fixed-dose design. When data were analyzed according to an alternate method of imputation (LOCF), OROS hydromorphone ER demonstrated statistically significant improvements in pain, stiffness, and physical function.

Abstract
Background Nuss surgery is preferred in pectus excavatum repair because this procedure produces excellent cosmetic results and prevents postoperative distressed pulmonary function. However, the procedure causes severe pain due to thoracic expansion. This study was designed to investigate the analgesic effect of small doses of ketamine on an intravenous patient-controlled analgesia (IV-PCA) using hydromorphone and ketorolac for pain control after Nuss surgery. Methods Forty-four patients undergoing elective Nuss surgery were randomly assigned to receive hydromorphone 3 µg/kg/hr, ketorolac 0.05 mg/kg/hr and ondansetron 0.1 mg/kg/day (Group HO, n = 22) or hydromorphone 3 µg/kg/hr, ketorolac 0.05 mg/kg/hr, ondansetron 0.1 mg/kg/day and ketamine 0.15 mg/kg/hr (Group HK, n = 22) via an IV-PCA pump after surgery. A blind observer evaluated each patient using the Modified Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) for the assessment of pain control. The total administered PCA volume, side effects and parents satisfaction with pain control were assessed at postoperative 1, 4, 8, 12, 24, and 48 hours. Results There were no significant differences in Modified CHEOPS between the groups during postoperative 48 hours. The total PCA volume in group HK was significantly lower than that in group HO (P < 0.05). The side effects in both groups did not significantly differ except for pruritus. The levels of satisfaction from the parents were not significantly different between the groups. Conclusions A small dose of ketamine on IV-PCA reduced the total administered dose of IV-PCA with hydromorphone and ketorolac and reduced the incidence of pruritus after the Nuss procedure in pediatric patients.

Abstract
Purpose The effectiveness of an opioid rotation to parenteral hydromorphone in advanced cancer patients has never been investigated. Therefore, the purpose of this study was to investigate the analgesic efficacy and side effects of parenteral hydromorphone on serious cancer-related pain. Methods We included 104 consecutive advanced cancer patients who were extensively pretreated with opioids. They were rotated to parenteral hydromorphone because they failed to achieve adequate pain relief on other opioids. Pain intensity and side effects were daily assessed. The moment of adequate pain control was defined as the first of at least 2 consecutive days when the mean pain intensity at rest was ≤4 (on a 0–10 numeric rating scale) and side effects were tolerable. Results The reasons for rotation to parenteral hydromorphone were inadequate pain control with/without expected delivery problems due to high opioid dosages (n = 61) and intolerable side effects with persistent pain (n = 43). Adequate pain control was achieved in 86 patients (83%) within a mean of 5 days. Eight of 86 patients still had side effects, but these were scored as acceptable. The mean pain intensity at rest decreased from 5.4 [standard deviation (sd) = 2.1] to 2.4 (sd = 1.5; p < 0.001). The median failure-free treatment period was 57 days and covered a substantial part of the median survival of 78 days in the responding patients. Conclusions In advanced cancer patients with serious unstable cancer-related pain refractory to other opioids, continuous parenteral administration of hydromorphone often results in long-lasting adequate pain control and should be considered even after extensive pretreatment with opioids.

Abstract
INTRODUCTION Acute pain in children may be undertreated. Improved understanding of developmental neurobiology and paediatric pharmacokinetics should facilitate better management of pharmacotherapy. The objective of this review is to discuss current paediatric practice and recent advances with these analgesic agents by using an evidence-based approach. AREAS COVERED Using PubMed an extensive literature review was conducted on the commonly used analgesic agents in children from 2000 to April 2010. EXPERT OPINION A multimodal analgesic regimen provides better pain control and functional outcome in children. The choice of pharmacological treatment is determined by the severity and type of pain. However, more research and evidence is required to determine the optimal drug combinations.

Abstract
OBJECTIVE This multicenter, double-blind, placebo-controlled study using a randomized withdrawal design evaluated the efficacy and safety of once-daily OROS hydromorphone ER in the treatment of opioid-tolerant patients with chronic moderate-to-severe low back pain (LBP). MAIN OUTCOME MEASURES The primary efficacy assessment was mean change in pain intensity based on patient diary Numeric Rating Scale (NRS) scores from baseline to final visit of the 12-week double-blind phase. Secondary endpoints included mean change from baseline to each visit in patient diary NRS scores; and office NRS scores; time to treatment failure; Patient Global Assessment; rescue medication use; and Roland Morris Disability Questionnaire total scores. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov NCT00549042. RESULTS For the primary outcome measure, hydromorphone ER significantly reduced pain intensity compared to placebo (p < 0.001). Median diary NRS score change from baseline to endpoint was significantly lower for OROS [corrected] hydromorphone ER (0.2 units) compared to placebo (1.6 units). [corrected] A significantly higher proportion of hydromorphone ER (60.6%) vs. placebo (42.9%) patients had at least a 30% reduction in diary NRS pain score from screening to endpoint (p < 0.01). Hydromorphone ER was well-tolerated, although 60 (13%) discontinued during the enrichment phase for adverse events and more active (9, 6.7%) than placebo (4, 3.0%) patients discontinued treatment for adverse events during the randomized phase. CONCLUSIONS These results provide evidence for the efficacy and safety of hydromorphone ER in opioid-tolerant patients with chronic moderate-to-severe LBP. Potential limitations include the shortened dose-conversion/titration phase, limiting the daily allowable dose of hydromorphone ER to 64 mg, and the allowance of limited rescue medication throughout the entire double-blind phase. Other trial design elements such as the use of an enrichment phase and the inclusion of only opioid tolerant patients may limit the generalizability of these results.

Abstract
Background Opioid analgesics have proven efficacy in the short-term management of chronic cancer pain, but data on their long-term use is more limited. OROS® hydromorphone is a controlled-release formulation of oral hydromorphone that may be particularly well suited to long-term management of chronic cancer pain because it provides stable plasma concentrations and consistent analgesia with convenient once-daily dosing. The objective of this study (DO-118X) was to characterise the pain control achieved with long-term repeated dosing of OROS® hydromorphone in patients with chronic cancer pain. Methods In this multicentre, phase III, open-label, single treatment, 1-year extension study, OROS® hydromorphone was administered to 68 patients with moderate-to-severe chronic cancer pain, who had successfully completed a short-term equivalence study, and whose pain was controlled with a stable dose of medication (≥ 8 mg OROS® hydromorphone or equivalent controlled-release morphine). Patients were started on the dose of OROS® hydromorphone equivalent to the opioid dose on which they achieved dose-stable pain control in the equivalence study; dose adjustments were made as necessary and breakthrough pain medication was permitted. Efficacy was assessed with the Brief Pain Inventory (BPI) and patient and investigator global evaluations of treatment effectiveness. No formal statistical analysis was done. Results The mean (standard deviation) duration of exposure to study medication was 139 (129.9) days and the mean (standard deviation) average daily consumption of OROS® hydromorphone was 43.7 (28.14) mg/day. All scores were maintained at a mild to moderate severity throughout the study; however, BPI scores for pain at its worst, pain at its least, pain on average, pain right now, and pain relief were slightly worsened at end point compared with baseline. Mean BPI pain interference with daily activities and patient and investigator global evaluation scores also remained generally stable. Treatment effectiveness was rated as fair to good throughout the study. The most frequently reported adverse events were nausea (n = 24, 35.3%), constipation (n = 22, 32.4%), and vomiting (n = 15, 22.1%). Conclusion The results of this extension study suggest that long-term repeated dosing with once-daily OROS® hydromorphone can be beneficial in the continuing management of persistent, moderate-to-severe cancer pain.

Abstract
UNLABELLED We conducted a prospective multicenter, open-label, escalating dose-range trial to compare, across patients, single intranasal doses (2, 4, 6, 8, and 10 mg) of hydromorphone HCl in the treatment of acute trauma pain The main outcome measure of pain-intensity reduction was derived from serial Numerical Pain-Rating Scores and calculated as the summed pain-intensity difference over 3 hours (SPID 3). Nasal examinations, vital signs, and adverse events were reported as safety outcomes. The mean decrease in pain intensity from baseline to 30 minutes was 39 to 44% for the 4-, 6-, 8- and 10-mg doses (n = 19, 33, 28, and 19 per group) and only 24% reduction for the 2-mg dose (n = 14). SPID 3 for the 2-mg dose was 40 to 50% below all other doses. There were no clinically meaningful changes in vital signs or nasal examinations. Adverse events (nausea, vomiting, pruritus, oxygen desaturation, bad taste, dizziness) were of mild to moderate intensity, increased with dose, and expected, based on route of administration and opioid pharmacology. Intranasal hydromorphone provides a component of rapid pain relief in the care of emergency department patients suffering from acute trauma pain. PERSPECTIVE This article presents a pilot dose-ranging study of intranasally administered hydromorphone, administered in the emergency department to patients suffering from acute trauma pain. This study demonstrates research success in this setting and noninjection-based delivery and certain doses of intranasal hydromorphone may be effective in treating acute trauma pain.

Abstract
The accurate assessment and effective treatment of acute pain in children in the hospital setting is a high priority. During the past 2 to 3 decades, pediatric pain management has gained tremendous knowledge with respect to the understanding of developmental neurobiology, developmental pharmacology the use of analgesics in children, the use of regional techniques in children, and of the psychological needs of children in pain. A wide range of medications is available to treat a variety of pain types. This article provides an overview of the most common analgesic medications and techniques used to treat acute pain in children.

Abstract
Opioid analgesics are essential in the treatment of moderate to severe cancer-related pain. Opioids are also recognized as important in the management of other severe, persistent refractory painful conditions, such as sickle cell disease and arthritis. In the clinical practice of pain management, stable opioid dosing generally depends on achieving maximal analgesia with tolerable side effects typical of opioid analgesics. There is a wide interindividual variability of responsiveness to exogenous opioids both in terms of analgesic efficacy and side effects. Optimizing pain management for the individual patient may require sequential trials of opioid medications until the regimen with the most favorable therapeutic ratio of efficacy to side effects is determined.

Abstract
BACKGROUND These recommendations have been developed to improve the care of intensive care unit (ICU) patients during the dying process. The recommendations build on those published in 2003 and highlight recent developments in the field from a U.S. perspective. They do not use an evidence grading system because most of the recommendations are based on ethical and legal principles that are not derived from empirically based evidence. PRINCIPAL FINDINGS Family-centered care, which emphasizes the importance of the social structure within which patients are embedded, has emerged as a comprehensive ideal for managing end-of-life care in the ICU. ICU clinicians should be competent in all aspects of this care, including the practical and ethical aspects of withdrawing different modalities of life-sustaining treatment and the use of sedatives, analgesics, and nonpharmacologic approaches to easing the suffering of the dying process. Several key ethical concepts play a foundational role in guiding end-of-life care, including the distinctions between withholding and withdrawing treatments, between actions of killing and allowing to die, and between consequences that are intended vs. those that are merely foreseen (the doctrine of double effect). Improved communication with the family has been shown to improve patient care and family outcomes. Other knowledge unique to end-of-life care includes principles for notifying families of a patient's death and compassionate approaches to discussing options for organ donation. End-of-life care continues even after the death of the patient, and ICUs should consider developing comprehensive bereavement programs to support both families and the needs of the clinical staff. Finally, a comprehensive agenda for improving end-of-life care in the ICU has been developed to guide research, quality improvement efforts, and educational curricula. CONCLUSIONS End-of-life care is emerging as a comprehensive area of expertise in the ICU and demands the same high level of knowledge and competence as all other areas of ICU practice.

Abstract
OBJECTIVE The purpose of this study was to investigate the pharmacokinetic properties of a novel, once-daily, controlled-release formulation of hydromorphone (OROS hydromorphone) in the presence of alcohol. RESEARCH DESIGN AND METHODS In a single-centre, open-label, four-treatment, four-period, four-sequence, crossover study, two groups of 24 healthy subjects (fasted or fed) were randomised to receive four single doses of OROS hydromorphone 16 mg with solutions of either 0%, 4%, 20% or 40% alcohol, and with a naltrexone block. MAIN OUTCOME MEASURES Plasma samples taken predose and at regular intervals up to 48 h after dosing were assayed for hydromorphone concentrations; a mixed-effect analysis of variance was done on log-transformed data. Bioequivalence was concluded if 90% confidence intervals of treatment mean ratios were between 80% and 125%. RESULTS Plasma hydromorphone concentrations were slightly higher after dosing with all alcohol treatments in both the fasted and fed subject groups. Median T(max) values were between 12 and 16 h and ranges were similar for all treatments. C(max) values increased after alcohol compared with no alcohol, with the increase slightly lower in the fed state. The greatest mean increase in C(max) observed was 1.3-fold in the fasted state and 1.1-fold in the fed state. Confidence intervals were within 80-125% for AUC but were slightly higher for C(max). CONCLUSIONS The pharmacokinetics of once-daily OROS hydromorphone were only minimally affected by alcohol, with no dose dumping of hydromorphone. The results indicate that the controlled-release properties of this formulation are maintained in the presence of alcohol.

Abstract
OBJECTIVE This study compared the efficacy and tolerability of a once-daily controlled-release formulation of hydromorphone (OROS) hydromorphone, Janssen-Cilag, Beerse, Belgium) and twice-daily extended-release (ER) oxycodone in patients with chronic, moderate to severe osteoarthritis (OA) pain. OROS hydromorphone is currently available only in Europe. METHODS Adults who met American College of Rheumatology clinical criteria for OA of the knee or hip with moderate to severe mean daily pain intensity despite chronic use of stable doses of NSAIDs or other nonsteroidal, nonopioid therapies were eligible for participation in this randomized, open-label study. The study consisted of a 14-day dose-titration and stabilization phase and a 28-day maintenance phase. OROS hydromorphone and ER oxycodone were initiated at dosages of 8 mg QD and 10 mg BID, respectively. Patients maintained diaries in which they rated their pain (from 0 = none to 3 = severe) and pain relief (from 0 = no relief to 4 = complete relief). Other assessments completed every 14 days included patient and investigator global evaluations of treatment effectiveness (scale from 1 = poor to 5 = excellent), the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index, and the Medical Outcomes Study (MOS) Sleep Scale. Adverse events (whether observed by study personnel, identified in response to questioning, or spontaneously reported) and vital signs were monitored throughout the study. The primary efficacy measures were the mean pain relief score at end point and the time from initiation of treatment to the third day of moderate to complete pain relief, as reported in the patient diary. Noninferiority analyses were conducted on all primary and secondary efficacy variables. RESULTS One hundred thirty-eight patients (71 OROS hydromorphone, 67 ER oxycodone) received treatment (safety population), and 83 (60.1%) completed the study. Data from 124 patients were included in the efficacy analyses; the majority of these patients were white (85.5%) and female (69.4%), with a mean age of 63.6 years. The most commonly affected joint was the knee (79.8 %). At end point, the OROS hydromorphone group had a mean pain relief score of 2.3 (median, 2.0) and the ER oxycodone group had a mean pain relief score of 2.3 (median, 2.3) (95% CI, -0.30 to infinity). The mean time to the third day of moderate to complete pain relief was 6.2 days (median, 4.0) in the OROS hydromorphone group and 5.5 days (median, 5.0) in the ER oxycodone group (95% CI, -0.31 to infinity). Mean pain intensity decreased from baseline to end point by 0.6 point in the OROS hydromorphone group and by 0.4 point in the ER oxycodone group. Mean scores on the patient global evaluation improved by a respective 1.2 and 1.0 points (median, 1 in both groups). Approximately two thirds of patients in each group (67.2% and 66.7%) rated the overall effectiveness of treatment as good to excellent at end point. There were no statistically significant differences between groups in total WOMAC scores at end point, and similar improvements from baseline in the WOMAC physical function, stiffness, and pain scales were observed in both groups. Whereas MOS sleep outcomes scores improved from baseline in both groups, OROS hydromorphone was associated with a significantly greater improvement on the MOS Sleep Problems Index I compared with ER oxycodone (P < 0.045). Adverse events were comparable in both groups; the most frequently reported adverse events were nausea (35.2% and 29.9%), constipation (29.6% and 25.4%), somnolence (25.4% and 17.9%), vomiting (16.9% and 11.9%), and dizziness (14.1% and 22.4%). Adverse events led to study discontinuation in 35.2% (25/71) of patients in the OROS hydromorphone group and 32.8% (22/67) in the ER oxycodone group. Discontinuations due to adverse events during the titration phase were numerically greater in the OROS hydromorphone group (29.6% [21/71]) than in the ER oxycodone group (19.4% [13/67]). Only 1 serious adverse event (diarrhea in a patient receiving OROS hydromorphone) was considered possibly related to study drug. CONCLUSIONS Once-daily OROS hydromorphone and twice-daily ER oxycodone provided similar pain relief in these patients with OA of the knee or hip. The tolerability profiles of the 2 agents were similar.
