最近发表的研究引发了一场骚动,研究人员所测试的各种胰岛素药瓶显示量要比应有的少得多。初步的研究表明,一些糖尿病患者可能正在注射药物,该药物已经部分崩解,即使有人对研究本身提出了严重的问题,也是也引起了人们的关注。

【胰岛素质量问题引起糖尿病专家关注】最近发表的研究引发了一场骚动,研究人员所测试的各种胰岛素药瓶显示量要比应有的少得多。初步的研究表明,一些糖尿病患者可能正在注射药物,该药物已经部分崩解,即使有人对研究本身提出了严重的问题,也是也引起了人们的关注。

研究提交人是一名药剂师,在多个药房购买了胰岛素小瓶,发现平均小瓶中有不到一半的标签,没有达到最低标准。这项研究仅对18瓶胰岛素进行了测试,但是糖尿病专家们人们这一数量太少,无法确定结果的有效性。除此之外,胰岛素生产商、患者倡导团体和糖尿病专家说,如果研究结果准确,糖尿病患者就会生病。

但是,鉴于对数百万糖尿病患者的潜在严重影响,研究人员们需要进行进一步的大规模研究来确定这一结果。所有的人都说病人应该按照规定继续使用胰岛素。小组正在讨论如何快速进行主要的研究,该研究将通过涉及多个研究实验室、不同的测试方法和更多不同胰岛素类型的样本来缓解恐惧。

美国糖尿病协会表示,大约600万美国人每天注射合成胰岛素,大多数患者使用注射器从瓶中抽取胰岛素,也就是在研究中测试的胰岛素,然后将其注射。增加的数字改为使用含有胰岛素筒的胰岛素笔,将它们压在皮肤上以注射一剂。

这项研究提出这样的警报,因为没有足够的胰岛素,糖尿病患者可能随时间而遭受失明、截肢和对肾脏和心脏的危及生命的损伤。

在《糖尿病科学和技术杂志》杂志中中,诺和诺德公司北美总部发表了初步研究,这表明一些糖尿病患者可能正在注射药物已经部分崩解,即使对研究本身提出了严重问题,也引起了人们的关注。这项小型研究测试了在多个药房购买的小瓶中的胰岛素溶液,包括诺和诺德制药公司和礼来公司和公司生产的胰岛素。他们的产品表明,他们符合严格的政府质量标准。胰岛素浓度和你给药的数量,如果发生变化,会产生巨大的后果。原始研究于12月21日发表在《糖尿病科学和技术》杂志上,测试了在堪萨斯州和密苏里州的不同批发商那里购买的药瓶中的胰岛素溶液。它们包括诺和诺德制药公司和礼来公司和公司生产的胰岛素。将液体溶液中的胰岛素单位的浓度或数量标记为100单位/毫升。美国密苏里州堪萨斯城大学医学院的一位药剂师表示,他们平均一半没有达到95%的最低标准。

美国食品药品监督管理局要求在离开工厂前对胰岛素批次进行测试。胰岛素必须保持凉爽,在狭窄的温度范围内,因为它被运到仓库,然后送到药房。FDA在此过程中进行抽查。有人认为胰岛素可能在工厂和药房之间太热了,导致一些分子破裂。

研究人员想知道,他的研究结果是否有助于解释为什么胰岛素使用者有时发现剂量不如正常水平。医生通常把这归咎于病人的错误:饭前没有注射足够的胰岛素,没有遵循饮食指南,或者不做运动。此次研究负责人表示,他的研究预算有限,他也承认研究规模太小,他的结果可能有缺陷。他将自己的研究结果通知了诺和诺德和礼来,希望有人能做一项更大的后续研究。
