Good Manufacturing Practices (GMP) are a set of guidelines proposed by the World Health Organization (WHO) to ensure that products manufactured for human consumption are consistently produced and controlled according to quality standards. These guidelines cover all aspects of production, from the starting materials to the final product.
WHO GMP guidelines provide a system for ensuring that:
- Products are continuously manufactured and monitored by established quality standards.
- Products are safe for human consumption.
- Production and quality control operations are clearly defined and reviewed.
- All crucial procedures undergo validation to guarantee uniformity and adherence to defined specifications.
- Manufacturing sites operate within a regulated environment to maintain control over processes.
- Training in GMP is conducted and records are maintained.
- Distribution procedures minimize any risk to product quality.
- Documentation is clear, legible, and retrievable.
- Self-inspections are conducted regularly to check adherence to GMP guidelines.
The primary goal of WHO GMP is to reduce the potential hazards associated with pharmaceutical manufacturing that cannot be completely eliminated by simply testing the finished product. By following the WHO GMP guidelines, manufacturers can minimize contamination risks and errors, avoid mix-ups, and ensure product quality. This in turn assures customers and consumers that the medicines they receive are safe and fit for purpose.
WHO GMP certification demonstrates that a company’s manufacturing practices meet the requirements to produce quality medicines. It indicates that the facility has the right infrastructure, documentation, quality control procedures and trained personnel in place. WHO GMP certification builds trust and credibility for manufacturers in the global pharmaceutical market. It also facilitates trade between countries since WHO GMP-approved products are easily accepted across borders.
