Eye irritation testing is a salient public issue and continues to escalate on the public agenda. Issues relevant to this milieu include legislative proposals to ban animal use for cosmetic testing, adequacy of the current standard (viz., the Draize Eye Irritancy Test), availability of non-animal methodologies, validation paradigm for new testing models, international harmonization of testing standards and methods, and the regulatory role in product testing and enforcement. The Food and Drug Administration (FDA) feels that enactment of legislation proposed to ban animal use from testing products for safety would pose serious problems from a public health perspective. FDA encourages the development of alternative test methods and is aware that many such tests are in various stages of evolution. At this time, however, none of these tests has been accepted by the scientific community as total replacement to the Draize test. FDA's basic positions on the use of non-animal alternatives are as follows: 1) The use of animal tests by industry to establish the safety of regulated products is necessary to minimize the risks from such products to humans, 2) The Draize eye irritancy test is currently the most valuable and reliable method for evaluating the hazard or safety of a substance introduced into or around the human eye, and 3) No non-animal tests are presently available to completely replace the Draize. FDA is actively involved with U.S. and international groups to harmonize protocols for product development, evaluate the current status of non-whole animal methodologies, and standardize testing requirements. The Agency has recently participated in several scientific symposia evaluating the status of non-whole animal methods in toxicity testing. Moreover, FDA representatives are currently scheduled to participate in international meetings and workshops planned for the immediate future addressing several issues in product safety determination.
眼部刺激试验是一个突出的公共问题,并且在公共议程上的重要性持续升级。与这一环境相关的问题包括禁止将动物用于化妆品试验的立法提案、现行标准(即德雷兹眼部刺激试验)的充分性、非动物试验方法的可用性、新试验模型的验证范式、试验标准和方法的国际协调,以及产品试验和执法中的监管作用。美国食品药品监督管理局(FDA)认为,从公共卫生角度来看,颁布旨在禁止将动物用于产品安全性试验的立法将带来严重问题。FDA鼓励开发替代试验方法,并意识到许多此类试验正处于不同的发展阶段。然而,目前这些试验均未被科学界接受为德雷兹试验的完全替代品。FDA在使用非动物替代方法方面的基本立场如下:1)行业使用动物试验来确定受监管产品的安全性对于将此类产品对人类的风险降至最低是必要的;2)德雷兹眼部刺激试验目前是评估引入人眼或眼周物质的危害或安全性最有价值和最可靠的方法;3)目前没有非动物试验可完全替代德雷兹试验。FDA积极参与美国和国际组织的工作,以协调产品开发方案、评估非全动物试验方法的现状并规范试验要求。该机构最近参加了几次评估非全动物方法在毒性试验中地位的科学研讨会。此外,FDA代表目前计划参加近期举行的国际会议和研讨会,这些会议和研讨会将讨论产品安全判定中的若干问题。
