ISO/TS 20451:2026

Overview

ISO/TS 20451:2026 provides a comprehensive framework for the implementation of ISO 11616 data elements and structures, facilitating the unique identification and exchange of regulated pharmaceutical product information. Developed by the International Organization for Standardization (ISO), this technical specification guides stakeholders in the health informatics and identification of medicinal products domains to associate pharmaceutical products or product groups with appropriate pharmaceutical product identifiers (PhPIDs).

The specification is part of the ISO IDMP (Identification of Medicinal Products) suite, which standardizes the structure and exchange of medicinal product information globally. ISO/TS 20451:2026 is primarily intended for regulatory authorities, pharmaceutical companies, software developers, and other stakeholders involved in the registration, regulation, and lifecycle management of medicinal products.

Key Topics

• Pharmaceutical Product Identification (PhPID): Defines how unique PhPIDs are generated and associated with medicinal products, focusing on elements such as substance, specified substance, strength, dose form, and device integration.
• Data Elements and Structures: Adheres to the data requirements set in ISO 11616, ensuring all relevant product aspects, including substance roles, strength, reference strength, and units of presentation are captured systematically.
• Cardinality and Strata: Establishes strict relationships between product elements (e.g., one dose form per PhPID, multiple active substances allowed), and introduces substance and specified substance strata for effective identification at various detail levels.
• Specifying Substances: Details the representation of specified substances using four groups of characteristics, facilitating detailed material descriptions, manufacturing information, grade/source association, and critical manufacturing processes.
• Strength Representation: Provides rules for documenting strength and concentration, particularly for liquid preparations, ensuring consistency in regulatory submissions and pharmacopoeial alignment.
• Integration with Other Standards: Encourages the use of related standards (ISO 11238, ISO 11239, ISO 11240, ISO 11615) and HL7 messaging formats (e.g., HL7 RIM, SPL, FHIR) for comprehensive data interoperability.

Applications

• Regulatory Submissions: Regulatory agencies can leverage this standard for the unambiguous identification and assessment of pharmaceutical products, enhancing the efficiency and transparency of medicinal product registration processes.
• Pharmaceutical Industry: Enables manufacturers and marketing authorization holders to manage product data in compliance with regulatory and international requirements, supporting global product lifecycle management and pharmacovigilance.
• Health Informatics Solutions: Provides software and system developers with technical guidance to implement robust data models for medicinal product information management, promoting interoperability and data exchange across jurisdictions.
• Data Exchange & Messaging: Facilitates the reliable transmission of structured product data by aligning with established messaging standards including HL7 V3 and FHIR, essential for regional and global electronic health information exchange initiatives.

Related Standards

• ISO 11616: Data elements and structures for unique identification and exchange of regulated pharmaceutical product information (core reference for ISO/TS 20451:2026).
• ISO 11238: Unique identification and exchange of regulated information on substances.
• ISO 11239: Data elements and structures for pharmaceutical dose forms, units of presentation, routes of administration, and packaging.
• ISO 11240: Units of measurement for health informatics and medicinal products.
• ISO 11615: Unique identification and exchange of regulated medicinal product information.
• ISO/TS 19844, ISO/TS 20440, ISO/TS 20443: Technical specifications for the implementation of specific data structures and elements defined in the IDMP standards.
• HL7 Messaging Standards: Including HL7 Reference Information Model (RIM), Common Product Model (CPM), Structured Product Labelling (SPL), and HL7 FHIR, all facilitate the electronic exchange of pharmaceutical product information.

By adhering to ISO/TS 20451:2026, organizations ensure regulatory compliance, enhance the traceability of pharmaceutical products, and contribute to improved patient safety and international public health outcomes through standardized product identification and information exchange.
