The production of medicines is a carefully controlled system where every stage influences the quality of the final product. The receipt of raw materials, material handling, manufacturing, packaging, quality control, and product release form a continuous chain that must operate as intended from start to finish.
This whole process follows international quality rules and practices that make sure every medicine batch meets the required standards.
– GMP is the minimum standard for production, and it is applied in all manufacturing sites, says Medimo’s Quality Expert, Qualified Person (QP), Sanna Tuhkala.
Although GMP includes many detailed requirements, its purpose is clear: ensuring patient safety. A medicine must contain the correct amount of active substances and remain consistent from one batch to the next.
Pharmaceutical quality assurance starts with people
Even though the pharmaceutical industry relies on advanced technology and automated systems, people still play a key role in production.
– Employee competence is ensured through training, hands-on experience, and continuous supervision, Sanna Tuhkala explains.
Because human error is one of the most significant risk factors in manufacturing, managing it is an important part of pharmaceutical quality assurance. Errors are prevented, for example, by restricting access to production areas to personnel whose work requires them to be there.
Quality assurance in pharma: raw material traceability
A safe final product is built on high-quality raw materials, whose quality is verified before use through inspection and testing. Upon arrival at the pharmaceutical manufacturing site, each batch of raw material is assigned a unique batch number that accompanies it throughout the entire production process, ensuring full traceability.
Cross-contamination is one of the key risk factors
One of the main goals of GMP is to prevent cross-contamination, meaning the mixing of products, materials, and batches.
Risk management begins already at the facility design stage. Ventilation systems, material flows, and equipment are designed to keep products separated. Equipment is also thoroughly cleaned, and personnel activities and processes are regularly monitored.
Pharmaceutical quality assurance requires validation and documentation
Before a production process is put into use, it must be confirmed that it works as intended. Validation demonstrates that a process, equipment, or method consistently produces results that meet quality requirements.
Alongside validation, documentation plays a central role throughout the product lifecycle. Every step is recorded so that it is possible to trace what has been done, when, on what basis, and by whom.
Even small errors in packaging can have an impact
GMP work continues after manufacturing. During packaging, it is ensured that the right product goes into the right packaging with the correct labels.
According to Sanna Tuhkala, it is especially important at this stage that packaging labels are clear, easy to read, and durable.
– For example, an incorrect label can result in a medicine appearing to be a different product than it actually is, she says.
Deviations are a core part of a quality management system in pharma
Deviations cannot be completely avoided in production. Therefore, GMP requires that all deviations are identified, investigated, and documented in a systematic way.
Deviation handling is often linked to the CAPA system, which is used to identify root causes and prevent recurrence.
– The CAPA system makes sure that lessons are learned from deviations and that they do not happen again in the future, Sanna Tuhkala says.
Risk assessment as part of pharmaceutical quality assurance
Risk assessment supports decision-making throughout the entire production process. It is used to identify critical steps and evaluate associated risks. Based on this, decisions are made on where control and more detailed oversight should be focused, whether in facility design, cross-contamination control, or change implementation.
Quality is built through collaboration
GMP requirements form a system with many instructions, checks, and documentation. Sanna Tuhkala says GMP is not achieved through processes and procedures alone.
– It requires skilled people, open communication, collaboration, and shared responsibility, she says.
