    背景:丁丙诺啡是阿片类药物使用障碍的有效且安全的治疗方法,但在开始治疗前需要出现中度阿片类药物戒断症状是一个重要的治疗障碍.
    方法:我们报告2例重症住院患者,活跃的阿片类药物使用障碍,其中我们开始使用经皮丁丙诺啡治疗超过48小时,然后给予单剂量舌下丁丙诺啡/纳洛酮,然后皮下缓释丁丙诺啡。患者没有经历沉淀戒断,只有轻度戒断症状。
    结论:这为可以提高耐受性的快速诱导策略提供了初步证据。照顾者的负担,与以前的诱导策略相比,治疗保留率。
    Buprenorphine is an effective and safe treatment for opioid use disorder, but the requirement for moderate opioid withdrawal symptoms to emerge prior to initiation is a significant treatment barrier.
    We report on two cases of hospitalized patients with severe, active opioid use disorder, in which we initiated treatment with transdermal buprenorphine over 48 h, followed by the administration of a single dose of sublingual buprenorphine/naloxone and then extended-release subcutaneous buprenorphine. The patients did not experience precipitated withdrawal and only had mild withdrawal symptoms.
    This provides preliminary evidence for a rapid induction strategy that may improve tolerability, caregiver burden, and treatment retention as compared to previous induction strategies.

    BACKGROUND: The buprenorphine transdermal system (BTDS) is approved in the US for the management of chronic pain. Due to its high affinity for μ-opioid receptors with a slow dissociation profile, buprenorphine may potentially displace or prevent the binding of competing μ-opioid-receptor agonists, including immediate-release (IR) opioids, in a dose-dependent manner. Health care professionals may assume that the use of IR opioids for supplemental analgesia during BTDS therapy is not acceptable.
    METHODS: This post hoc analysis evaluated the use of IR opioids as supplemental analgesia during the management of moderate-severe chronic pain with BTDS at 52 US sites (BUP3015S, NCT01125917). Patients were categorized into IR-opioid and no-IR-opioid groups. At each visit of the extension phase, adverse events, concomitant medications, and information from the Brief Pain Inventory (BPI) were recorded.
    RESULTS: The most common supplemental IR opioids prescribed during BTDS treatment (n=354) were hydrocodone-acetaminophen and oxycodone-acetaminophen. The mean daily dose of IR opioids (morphine equivalents) for supplemental analgesia was 22 mg. At baseline, BPI - pain intensity and BPI - interference scores were higher for patients in the IR-opioid group. In both treatment groups, scores improved by week 4, and then were maintained throughout 6 months of the open-label extension trial. The incidence of treatment-emergent adverse events was similar in both groups.
    CONCLUSIONS: Patients who were prescribed IR opioids reported lower scores for BPI pain intensity and pain interference to levels similar to patients receiving BTDS without IR opioids, without increasing the rate or severity of treatment-emergent adverse events. Patients prescribed concomitant use of IR opioids with BTDS had greater treatment persistence. The results of this post hoc analysis provide support for the concomitant use of IR opioids for supplemental analgesia during the management of moderate-severe chronic pain with BTDS.

    Management of complex regional pain syndrome (CRPS) can be challenging. Various pharmacological approaches have produced mixed results. Buprenorphine activates mu-opioid receptors and antagonizes kappa and delta receptors, acts at N-methyl-d-aspartate (NMDA) receptor, and is an orphan-related ligand-1 receptor agonist. It is available in transdermal patches that last for up to 7 days. This report describes two patients with refractory CRPS who were treated with transdermal buprenorphine. The patients experienced approximately 50% reduction in pain intensity scores. Application site rash that occurred was managed with topical steroid spray used before applying the patch.

    Prescription opioid abuse and diversion are major causes of morbidity and mortality in the United States. The buprenorphine transdermal delivery system (BTDS) is indicated for the treatment of moderate to severe chronic pain and provides a continuous dose of 5, 7.5, 10, 15, or 20 μg/h buprenorphine for 7 days. Quarterly rates of abuse and diversion of BTDS were compared with 4 comparator groups: 1) other buprenorphine products, 2) fentanyl patches, 3) extended-release (ER) opioid tablets/capsules, and 4) ER tramadol. Data were obtained from the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS) System Poison Center, Drug Diversion, Treatment Programs Combined (Opioid Treatment and Survey of Key Informants\' Patients Programs), and College Survey Programs. Rates were calculated using case counts per population and mentions per prescriptions filled. Poisson regression analysis was used to compare mean rates over time across drug groups after allowing for drug group-specific dispersion parameters. Population adjusted abuse rates were low for BTDS in all of the RADARS System programs compared with the other comparator groups. Findings were similar for the prescription adjusted rates, with BTDS reported at the lowest rates in all programs. Route of abuse differed slightly for BTDS and the comparator groups depending on the program. BTDS was abused and diverted at low rates compared with the other opioid groups in 5 programs of the RADARS System using either population-based rates or prescription dispensed rates.
    Data from the RADARS System show the BTDS is abused and diverted at low rates compared with other opioid groups including other forms of buprenorphine, fentanyl patches, ER opioid formulations, and ER tramadol.

    OBJECTIVE: This study examines the efficacy of the buprenorphine transdermal system (BTDS) for reducing the interference of pain on physical and emotional functioning associated with chronic low back pain (CLBP).
    METHODS: A post-hoc analysis used data from a randomized, placebo-controlled, double-blind trial of patients with moderate-to-severe CLBP. The Brief Pain Inventory (BPI) measured pain interference at screening, following a run-in period, and during the 12-week double-blind treatment phase. Statistical analyses examined treatment arm differences (BTDS vs placebo) for the following: BPI Interference subscale items and subscale scores at the trial end point (week 12); patterns of change in the Interference subscale scores over time; proportions of patients indicating mild or no interference following treatment; and proportions of patients showing improvement (30%, 50%, 2-point, or 4-point change in score from screening to week 12) for each item and subscale.
    RESULTS: Mean scores for BPI Interference items and Interference subscale were significantly lower (ie, indicated less interference) for BTDS than for placebo (all P < 0.001). Treatment arm differences in Interference subscale scores emerged within 4 weeks of treatment. The BTDS patients were significantly more likely to indicate mild/no interference on 5 of 7 Interference subscale items following treatment (P < 0.05). For most comparisons, BTDS patients were significantly more likely to show criterion-level improvements in Interference item and subscale scores (P < 0.05 for differences).
    CONCLUSIONS: Results indicate the efficacy of BTDS treatment, compared with placebo, for reducing the interference of pain on physical and emotional functioning in patients with moderate-to-severe CLBP. The advantage of BTDS was observed within 4 weeks of treatment, and was maintained throughout the 12-week treatment phase.
