GMP stands for Good Manufacturing Practice. It is the part of quality assurance that supports medicines being consistently produced and controlled to the quality standards appropriate to their intended use and applicable authorisation or specification.
Why is GMP important?
People rely on medicines having the quality they are supposed to have. GMP provides a framework for controlling the processes that make and test those medicines, including the risks of contamination, mix-ups and errors.
Quality cannot depend only on testing the finished product. It also depends on trained people, suitable facilities and equipment, controlled materials, defined processes and reliable records throughout manufacture.
What does GMP look like in practice?
A pharmaceutical quality system connects responsibilities, procedures and records. It helps teams control routine work and manage deviations, investigations, corrective and preventive actions, change control and ongoing improvement.
- People understand their responsibilities and receive training appropriate to their work.
- Facilities, utilities and equipment are suitable for their intended use and maintained under control.
- Materials, production and packaging activities are defined and traceable.
- Documents and records accurately describe what should happen and what actually happened.
- Quality Control activities support decisions about materials and products.
- Problems and proposed changes are assessed, documented and followed through.
What is the difference between GMP, QA and QC?
Quality Assurance (QA) covers the arrangements used to achieve the intended quality. GMP is a key part of that system for manufacturing medicines. Quality Control (QC) includes activities such as sampling, specifications and testing that help determine whether quality requirements are met.
These are connected responsibilities. A laboratory result does not, by itself, demonstrate that every manufacturing activity was controlled appropriately. Our QA, QC and QMS lessons introduce how the different parts fit together.
GMP and GDP are connected
GMP addresses manufacture and control. GDP addresses the distribution chain, including storage, transport and handling. Maintaining medicine quality depends on both: careful manufacture can be undermined by unsuitable distribution conditions.
Where can I get free GMP training?
Start with our introductory GMP video, then explore pharmaceutical quality systems, QA, QC, validation, change control and internal audits. The videos are free to access on this site and the Help Me GxP YouTube channel.
Use these explanations alongside current official guidance and your organisation’s training programme. Watching a video does not confer a regulatory qualification or replace demonstrated competence for your role.
