Unique Ingredient Identifier

**Overview**
This data package contains the details of substances in drugs, biologics, foods and devices registered with a Unique Ingredient Identifier (UNII) through the joint FDA/USP Substance Registration System (SRS). It also contains a list of the names used for each UNII and the changes made to Unique Ingredient Identifiers' (UNIIs) descriptions to the latest update.

**Description**
The Unique Ingredient Identifier (UNII) is a non-proprietary, free, unique, unambiguous, non-semantic, alphanumeric identifier based on a substance's molecular structure and/or descriptive information. The UNII is:
- One of the core components of the United States Federal Medication Terminology.
- Used in the FDA's Structured Product Labeling
- Used to assist in the generation of the National Library of Medicine's (NLM's) RxNorm.
- A US government standard for drug ingredient and food allergen identifiers
- A component of the Environmental Protection Agency's Substance Registry System (future) The overall purpose of the joint FDA/USP Substance Registration System (SRS) is to support health information technology initiatives by generating unique ingredient identifiers (UNIIs) for substances in drugs, biologics, foods, and devices.

The UNII is a non- proprietary, free, unique, unambiguous, non-semantic, alphanumeric identifier based on a substance’s molecular structure and/or descriptive information. The procedures and management of the SRS is provided by the SRS Board. The SRS Board includes experts from both FDA and USP. The SRS operating procedures defined by the SRS Board are detailed in the SRS Manual. The UNII is a core component of the US Federal Medication Terminology, it is used for product labeling, to assist in the generation of RxNorm, as an identifier for drug ingredients and allergens and in the future will be a component of the Environmental Protection Agency's Substance Registry System. The UII is useful for understanding data contained in NLM's Unified Medical Language System, National Cancer Institute Enterprise Vocabulary Service, FDA Data Standards Council website, VA National Drug File Reference Terminology, FDA Inactive Ingredient Query Application and, proximately, USP Dictionary of USAN and International Drug Names.

**Benefits**
- The overall purpose of the joint fda/usp substance registration system (srs) is to support health information technology initiatives by generating unique ingredient identifiers (uniis) for substances in drugs, biologics, foods, and devices.

**Data Engineering Overview**
**We deliver high-quality data**
- Each dataset goes through 3 levels of quality review
- 2 Manual reviews are done by domain experts
- Then, an automated set of 60+ validations enforces every datum matches metadata & defined constraints
- Data is normalized into one unified type system
- All dates, unites, codes, currencies look the same
- All null values are normalized to the same value
- All dataset and field names are SQL and Hive compliant
- Data and Metadata
- Data is available in both CSV and Apache Parquet format, optimized for high read performance on distributed Hadoop, Spark & MPP clusters
- Metadata is provided in the open Frictionless Data standard, and its every field is normalized & validated
- Data Updates
- Data updates support replace-on-update: outdated foreign keys are deprecated, not deleted

**Our data is curated and enriched by domain experts**

Each dataset is manually curated by our team of doctors, pharmacists, public health & medical billing experts:
- Field names, descriptions, and normalized values are chosen by people who actually understand their meaning
- Healthcare & life science experts add categories, search keywords, descriptions and more to each dataset
- Both manual and automated data enrichment supported for clinical codes, providers, drugs, and geo-locations
- The data is always kept up to date – even when the source requires manual effort to get updates
- Support for data subscribers is provided directly by the domain experts who curated the data sets
- Every data source’s license is manually verified to allow for royalty-free commercial use and redistribution.

**概览**
本数据包涵盖了通过美国食品药品监督管理局（FDA）与美国药典委员会（USP）联合建立的物质注册系统（Substance Registration System, SRS），获得唯一成分标识符（Unique Ingredient Identifier, UNII）的药品、生物制品、食品及医疗器械中的物质详情。同时包含各UNII所使用的名称列表，以及截至最新版本的UNII描述变更记录。

**数据集详情**
唯一成分标识符（Unique Ingredient Identifier, UNII）是基于物质分子结构及/或描述性信息生成的非专有、免费、唯一、无歧义、非语义化的字母数字标识符。UNII具备以下属性：
- 美国联邦药物术语体系的核心组成部分之一
- 应用于美国食品药品监督管理局（FDA）的结构化产品标签（Structured Product Labeling）
- 辅助生成美国国家医学图书馆（National Library of Medicine, NLM）的RxNorm标准
- 美国政府用于药品成分及食品过敏原标识符的官方标准
- 未来将纳入美国环境保护署（Environmental Protection Agency, EPA）物质注册系统

FDA与USP联合建立的物质注册系统（Substance Registration System, SRS）的核心目标，是通过为药品、生物制品、食品及医疗器械中的物质生成UNII，为健康信息技术项目提供支撑。

UNII是基于物质分子结构及/或描述性信息生成的非专有、免费、唯一、无歧义、非语义化的字母数字标识符。物质注册系统（SRS）的流程与管理由SRS委员会负责，该委员会由FDA与USP的专家组成。SRS委员会制定的SRS操作细则详见《SRS手册》。UNII作为美国联邦药物术语体系的核心组成部分，可用于产品标签、辅助生成RxNorm标准、作为药品成分与过敏原的标识符，未来还将成为EPA物质注册系统的组成部分。UNII可用于解析美国国家医学图书馆统一医学语言系统、美国国家癌症研究所企业词汇服务、FDA数据标准委员会官网、退伍军人事务部国家药品文件参考术语、FDA非活性成分查询应用程序，以及近期的USP美国采用名称（USAN）与国际药品名称词典中的数据。

**优势**
- FDA与USP联合物质注册系统（SRS）的核心目标，是通过为药品、生物制品、食品及医疗器械中的物质生成唯一成分标识符（UNII），为健康信息技术项目提供支撑。
