Good Documentation Practice (GDP) in pharmaceuticals

Documentation is the cornerstone of any company’s Quality Management System and is an essential GMP requirement. Good Documentation Practice is critical that anyone dealing with GMP documents and documentation systems understands the regulatory requirements.

Requirement of Good Documentation Practice?

Good Documentation Practice

Good Documentation Practice is essential for Proof of invention, Company operations, Technology Transfer, Regulatory Requirements, and Liability Protections.

The Documentation System is What needs to get documented, What should get documented, Ensure comprehensive documentation, Avoiding contradiction in documents and Document control.

Directive Documents are Specifications, STPs, SOPs, Master Batch Records, and Validation Protocols.

Data Collection Documents like Production Batch Records, QC Records – COA, Validation Records, Equipment and Facility Logbooks, Calibration and Maintenance Records, Vendor History Files.

Reports likes, Validation Reports, Facility Qualification Report, Product Development Report, and Process Flow Diagrams.

Understand Good Documentation Practice GDP in pharma:

Good Documentation Practices help organizations to efficiently create and control documents across all parts of their business.

GDP provides legal Proof that work was adequately planned and performed at the claimed time. It helps in the troubleshooting of technical and managerial problems. It provides a written history of the company and products, and it provides to regulators that the company follows its commitments.

GMP documents must be clear, comprehensive, not overlapping in their content, and must cover all essential aspects in sufficient detail. Documentation failure comprises a significant percentage of non-conformances during GMP audits. Develop standards for preparing documentation and establishing the document structure. There must be an Outline guideline for reviewing and correcting documentation, improving the review and approval process. Develop strategies to revise existing documentation.

Write concise documents that are user-friendly. A document numbering method should be agreed upon to simplify and standardize tracking and minimize confusion due to frequent changes. Careful planning is required to manage links and referrals between documents to ensure that an approved document does not refer to an unapproved one. Too many referrals in documents may result in operational problems; it is helpful to review the referrals to determine if they are necessary.

Documents shall specify the Title, Purpose/ Objective, and Scope. Reproduced documents should be clear and legible. Any alteration made in the entry of a document/ record shall be signed and dated if there is an alteration of any critical result or value that must be reasoned out. Recording of data must be concurrent.
