Study Notes

What is GMP

GMP is a quality assurance system for pharmaceutical production ensure that drug products meet rigorous quality and regulatory standards
GMP primarily aims to diminish the risks of:
- Cross-contamination
- Mix-ups caused by incorrect labeling
GMP is a set of principles and procedures that manufacturers follow to ensure the required quality of therapeutic products.
cGMP emphasizes promoting continual advancement to keep up with industry developments

GMP Evolution

The first GMP text was published by WHO during 1967-69
The FDA adopted the term cGMP in 1978 to emphasize that guidelines are constantly evolving
GMP guidelines were revised and expanded during 1989-90
WHO published GMP guidelines in 1996 for the validation of manufacturing processes.

Importance of GMP

Poor quality medicine can contain harmful substances that have been added unintentionally
Medicines with insufficient active ingredients will not have the intended therapeutic effect
GMP boosts pharmaceutical export opportunities:
- Most countries only accept medicine manufactured according to internationally recognized GMP standards
- Countries that require GMP for pharmaceutical production and train inspectors on GMP requirements increase their export potential

Specific GMP Requirements

All manufacturing processes must be clear defined, systematically reviewed and consistently manufacture products that meet quality specifications
Qualification and validation must be performed
Necessary resources must be provided, including:
- Qualified and trained personnel
- Adequate premises and space
- Suitable equipment and services
- Appropriate materials, containers, and labels
- Approved procedures and instructions
- Suitable storage and transport
- Adequate personnel, laboratories, and equipment for in-process controls
Operators are trained to follow correct procedures

Specific GMP Requirements continued

Instructions and procedures must be clear and specifically applicable to the facilities
Records are made manually or electronically during manufacturing to show that the required procedures are followed. When significant deviations are reported they must be fully recorded and investigated
Records for manufacturing and distribution that provide a history of each batch must be retained in an accessible and understandable form
Proper storage and distribution must minimize risk to product quality
A system must be in place to recall batches of product from sale
Complaints about marketed products must be examined, causes investigated, and appropriate measures taken to prevent recurrence

Glossary of Terms continued

Reconciliation: A comparison between theoretical and actual quantities
Standard operating procedure (SOP): Written instructions for performing operations not specific to a given product or material.
Validation: The process of proving that a procedure, process, equipment, material, activity, or system has produced the expected results.
Calibration: Establishing a relationship between values indicated by an instrument, and the corresponding known values of a reference standard.
Reprocessing: Subjecting all or part of a batch or lot of a drug to a previous validated step in the manufacturing process if specifications are not met.
Reworking: Subjecting an in-process or bulk product to an alternate manufacturing process if specifications are not met.
Packaging: All operations (including filling and labeling) that a bulk product undergoes to become a finished product.
Packaging material: Any material (including printed material) employed in the packaging of a pharmaceutical.
Large-volume parenterals: Sterile solutions intended for parenteral administration with a volume of 100 ml or more.

Quality Assurance (QA)

Quality assurance: A wide-ranging concept covering all matters that influence the quality of a product.
QA system: Ensures that:
- Pharmaceutical products are designed and developed in a way that complies with GMP requirements and other associated codes (GLP, GCP)
- Production and control operations are specified in writing and GMP requirements are adopted.
- Managerial responsibilities are specified in job descriptions
- Correct starting and packaging materials are used
- All necessary controls are performed on starting materials, intermediates, bulk products, and finished products
- The finished product is processed and checked correctly according to defined procedures
- Pharmaceutical products are not sold or supplied before authorized personnel confirm that each production batch has been produced and controlled according to the marketing authorization and relevant regulations.
- Deviations are reported, investigated, and recorded
- There is a procedure for self-inspection and/or quality audit that regularly appraises the quality assurance system.
