Good Distribution Practices (GDP) establish the requirements that must be met by entities involved in the distribution of active pharmaceutical ingredients (APIs) to ensure that their quality and integrity are maintained throughout the supply chain. Within this framework, data integrity and documentation control are key elements to ensure regulatory compliance and the protection of public health.
Data integrity, in the context of GDP, ensures that all information generated during distribution activities is reliable, complete, and verifiable. This includes data related to receipt, storage, transportation, batch traceability, temperature control, deviation management, complaints, and recalls. Records must comply with the ALCOA principles, ensuring that data are attributable, legible, contemporaneous, original, and accurate. Any deficiencies in data management may compromise the distributor’s ability to demonstrate that APIs have been handled in accordance with GDP requirements.
Documentation control is a fundamental GDP requirement, as it provides the necessary documented evidence to demonstrate compliance with defined processes. Standard Operating Procedures (SOPs), records, technical agreements, certificates of analysis, and transportation documentation must be properly approved, kept up to date, and protected against unauthorized use or obsolete versions. An effective documentation control system ensures data consistency, facilitates traceability, and supports the correct execution of operations.
GDP also requires that systems used for data and document management, whether paper-based or electronic, are adequately controlled. In the case of computerized systems, these must be validated and include access controls, audit trails, and mechanisms to prevent data loss or unauthorized modification. In addition, continuous training of personnel in GDP, data integrity, and documentation management is essential to minimize errors and promote a strong culture of quality and compliance. In conclusion, data integrity and documentation control are essential pillars of GDP compliance in the distribution of APIs.
Their proper implementation not only enables compliance to be demonstrated during inspections by regulatory authorities but also ensures that active pharmaceutical ingredients maintain their quality, safety, and traceability until their use in medicinal product manufacturing.
