- ICH Q7, titled Good Manufacturing Practice Guide for Active Pharmaceutical Ingredients, is a globally harmonized guideline developed by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH).
- Published in 2000, ICH Q7 provides comprehensive Good Manufacturing Practice (GMP) principles specifically tailored for the manufacturing of Active Pharmaceutical Ingredients (APIs)—both chemical and biological. It sets out the expectations for quality systems, documentation, and operational controls to ensure that APIs used in drug products are consistently produced and controlled to meet appropriate quality standards.
- The guideline is structured into 20 sections that collectively cover all aspects of API manufacturing, from development through commercial production. It begins with Section 1 (Introduction) and Section 2 (Quality Management), which establish the scope and emphasize the importance of a robust quality system. These sections stress that quality must be built into every stage of the manufacturing process, supported by documented procedures, trained personnel, and independent quality units. ICH Q7 advocates a risk-based approach, allowing flexibility based on the type of API and the stage of production, especially for early intermediates versus final APIs.
- Section 3 (Personnel) and Section 4 (Buildings and Facilities) detail the expectations for qualified staff and appropriate facility design. Personnel must be adequately trained, with roles and responsibilities clearly defined, while facilities must be designed to minimize contamination and cross-contamination. Cleanliness and hygiene are critical, and the guideline requires separate areas for different materials where necessary.
- Equipment, covered in Section 5, must be appropriately designed, maintained, cleaned, and calibrated to prevent product contamination or mix-ups. Documentation and records, described in Section 6, are essential for traceability and accountability. All procedures, deviations, and changes must be clearly documented, reviewed, and retained for specified periods to support regulatory inspections and audits.
- Production and in-process controls (Section 7), laboratory controls (Section 11), and packaging and labeling (Section 9) form the operational core of the guideline. These sections require validated processes, specifications for raw materials and intermediates, and testing protocols for final APIs. Proper labeling and packaging must ensure correct identification and prevent mislabeling or contamination. ICH Q7 emphasizes the need for change control, investigation of deviations, and corrective and preventive actions (CAPA) throughout the lifecycle of the API.
- Special attention is given to materials management in Section 8, which includes requirements for sampling, testing, and storage of raw materials and intermediates. Validation (Section 12) is required for key manufacturing processes, analytical methods, and cleaning procedures to confirm that they consistently yield acceptable results. ICH Q7 also requires adequate control of impurities, microbiological quality (where relevant), and stability data to ensure API quality over its shelf life.
- The guideline further covers agents, brokers, traders, and distributors (Section 17), recognizing the importance of supply chain integrity. It mandates appropriate oversight of these third parties to ensure that all materials meet GMP standards and are not counterfeited or mishandled. Sections on contract manufacturers (Section 16) and product complaints and recalls (Section 15) emphasize the manufacturer’s ultimate responsibility for the quality and safety of the APIs, regardless of outsourcing.
- In summary, ICH Q7 is a globally accepted GMP framework for the production of APIs, aimed at ensuring quality, safety, and regulatory compliance across international markets. It bridges the gap between regulators and industry by harmonizing expectations, facilitating international trade, and supporting mutual recognition agreements between regulatory authorities. Compliance with ICH Q7 is not only a regulatory requirement in many jurisdictions (such as the EU, U.S., and Japan), but also a critical element in building trust with customers and partners throughout the pharmaceutical supply chain.
