Background: Controlled-release oxycodone/naloxone(OXN-CR) maintains the effect of opioid-induced analgesia through oxycodone while reducing the occurrence rate of opioid-induced constipation through naloxone. The present study was designed to assess the non-inferiority of OXN-CR to controlled-release oxycodone(OX-CR) for the control of cancer-related pain in Korean ***: In this randomized, open-labeled, parallel-group, phase IV study, we enrolled patients aged 20 years or older with moderate to severe cancer-related pain [numeric rating scale(NRS) pain score ≥4] from seven Korean oncology/hematology centers. Patients in the intention-to-treat(ITT) population were randomized(1:1) to OXNCR or OX-CR groups. OXN-CR was administered starting at 20 mg/10 mg per day and up-titrated to a maximum of80 mg/40 mg per day for 4 weeks, and OX-CR was administered starting at 20 mg/day and up-titrated to a maximum of 80 mg/day for 4 *** primary efficacy endpoint was the change in NRS pain score from baseline to week4, with non-inferiority margin of-1.5. Secondary endpoints included analgesic rescue medication intake, patientreported change in bowel habits, laxative intake, quality of life(QoL), and safety ***: Of the ITT population comprising 128 patients, 7 with missing primary efficacy data and 4 who violated the eligibility criteria were excluded from the efficacy analysis. At week 4, the mean change in NRS pain scores was not significantly different between the OXN-CR group(n = 58) and the OX-CR group(n = 59)(-1.586 vs.-1.559,P = 0.948). The lower limit of the one-sided 95% confidence interval(-0.776 to 0.830) for the difference exceeded the non-inferiority margin(P < 0.001). The OXN-CR and OX-CR groups did not differ significantly in terms of analgesic rescue medication intake, change in bowel habits, laxative intake, QoL, and safety ***: OXN-CR was non-inferior to OX-CR in terms of pain reduction after 4 weeks of treatmen

Progress and challenges for replacing n-methyl-2-pyrrolidone/polyvinylidene fluoride slurry formulations in lithium-ion battery cathodes

引用

Progress in Natural Science:Materials International 2024年第01期34卷 194-206页

作者： sung Cik Mun Yeong Hoon Jeon Jong Ho Won Battery Materials Research Center LG Chem Department of Energy Engineering Dankook University

With electric vehicles, energy storage systems, and portable electronic devices becoming increasingly popular, the demand for lithium-ion batteries has surged considerably. In the lithium-ion battery industry, n-methyl-2-pyrrolidone(NMP) is widely used as the solvent for cathode slurry, and polyvinylidene fluoride(PVDF) is used as the cathode binder. However, because of the harmful effect of NMP on the environment and human health, the use of NMP and PVDF for lithium-ion batteries will be highly regulated in the future. Therefore, developing eco-friendly alternatives is crucial for formulating systems using new solvents and binders. Despite numerous efforts, these alternatives have not been widely adopted across the lithium-ion battery industry. It is due to their limited ability to compete on price or performance to replace the traditional NMP/PVDF slurry formulations. This review investigates developments in the search for new solvents and binders that can be used in cathode slurry compositions. The new systems can potentially decrease energy consumption and manufacturing costs associated with NMP recovery, energy-intensive drying processes, and material expenses. We discuss key factors and technical challenges from earlier studies and compare them with the current, optimized formulations based on NMP and PVDF.

背景与目的羟考酮/纳洛酮控释片(controlled?release oxycodone/naloxone,OXN?CR)通过羟考酮发挥阿片类药物诱导的镇痛效果,同时纳洛酮可降低阿片类药物引起的便秘的发生率。本研究旨在评价与羟考酮控释片(controlled?release oxycodone,OX?CR)相比,OXN?CR在控制韩国患者癌性疼痛中的非劣效性。方法本项随机、开放标签、平行分组、IV期研究中,我们从韩国的7个肿瘤学/血液学中心招募了年龄20岁及以上、具有中重度癌性疼痛的患者[疼痛数字评价量表(numeric rating scale,NRS)疼痛评分≥4分]。意向治疗人群(intention天20 mg/10 mg,每天最大?to用?treat,ITT)随机(1:1)分为OXN?CR和OX?CR组。OXN?CR组:起始用药量为每药量80 mg/40 mg,用药4周。OX?CR组:起始用药量为20 mg/d,最大用药量为80 mg/d,用药4周。本研究的主要疗效终点为NRS疼痛评分从基线到第4周的变化,其非劣效性界值为-1.5。次要终点包括应急镇痛药摄入量、患者报告的排便习惯改变、缓泻药摄入量、生活质量(quality of life,QoL)及安全性评价。结果 128例患者组成的ITT人群中,7例因缺失主要疗效数据、4例因不符合资格标准被排除疗效分析。在第4周时,OXN?CR组(n=58)和OX?CR组(n=59)患者NRS疼痛评分的平均变化无显著性差异(-1.586 vs.-1.559,P=0.948)。组间差异的单侧95%置信区间(-0.776-0.830)的下限超过非劣效性边界(P <0.001)。OXN?CR和OX?CR两组患者在应急镇痛药摄入量、排便习惯改变、缓泻药摄入量、QoL和安全性评价方面均无显著差异。结论就治疗4周后减轻患者疼痛的效果而言,OXN?CR的疗效非劣于OX?CR,两者具有相似的安全性。对于OXN?CR在长期疼痛控制和缓解便秘方面的疗效,则需在更多韩国癌性疼痛患者人群中开展进一步的研究。
