FHIR-Based Electronic Product Information (ePI): A Practical Guide for Structuring Pharma Labeling

Details

The European Medicines Regulatory Network (EMRN) provides an implementation guide detailing how HL7 FHIR is used to generate electronic product information (ePI) according to the EU ePI Common Standard. This serves as a practical technical reference for pharmaceutical companies and technology providers preparing for future submissions to EU regulators. FHIR, originally developed for clinical data exchange, uses its standardized, machine-readable format to enable capabilities impossible with traditional document formats like PDFs: structured data that can be computationally processed, explicitly defined relationships between components, and granular version control. This allows complex queries, such as identifying contraindications based on dosage form. In ePI, content is exchanged as a structured package using FHIR resource types like Bundle, List, and Composition. Specific resources define key elements: MedicinalProductDefinition (drug name, ingredients) and PackagedProductDefinition (physical packaging). These resources form the operational layer for structuring pharma labeling data. The guide defines not just concepts but concrete technical specifications and constraints required to generate ePI XML files that can be validated against the EU ePI Common Standard. This provides critical guidance for companies building structured content management systems, moving beyond free-form prose.
