What is GMP?
Good manufacturing practice (GMP) is a system for ensuring that products are consistently produced and controlled according to quality standards. It is designed to minimize the risks involved in any pharmaceutical production that cannot be eliminated through testing the final product. The main risks are: unexpected contamination of products, causing damage to health or even death; incorrect labels on containers, which could mean that patients receive the wrong medicine; insufficient or too much active ingredient, resulting in ineffective treatment or adverse effects. GMP covers all aspects of production; from the starting materials, premises and equipment to the training and personal hygiene of staff. Detailed, written procedures are essential for each process that could affect the quality of the finished product. There must be systems to provide documented proof that correct procedures are consistently followed at each step in the manufacturing process - every time a product is made. WHO has established detailed guidelines for good manufacturing practice. Many countries have formulated their own requirements for GMP based on WHO GMP. Others have harmonized their requirements, for example in the Association of South-East Asian Nations (ASEAN), in the European Union and through the Pharmaceutical Inspection Convention.
cGMP Regulations and Practices
Process validation is
required, in both general and specific terms, by the Current Good Manufacturing
Practice Regulations for Finished Pharmaceuticals, 21 CFR Parts 210 and 211.
Examples of such requirements are listed below for informational purposes, and
are not all-inclusive.
A requirement for
process validation is set forth in general terms in Section 211.100 --
Written procedures; deviations -- which states, in part:
"There
shall be written procedures for production and process control designed to
assure that the drug products have the identity, strength, quality, and purity
they purport or are represented to possess."
Several sections of the CGMP regulations state validation requirements in more specific terms. Excerpts from some of these sections are:
Section 211.110, Sampling and testing of in-process materials and drug products.
(a) "....control procedures shall be established to monitor the output and VALIDATE the performance of those manufacturing processes that may be responsible for causing variability in the characteristics of in-process material and the drug product." (emphasis added)
Section 211.113, Control of Microbiological Contamination.
(b) "Appropriate written procedures, designed to prevent microbiological contamination of drug products purporting to be sterile, shall be established and followed. Such procedures shall include VALIDATION of any sterilization process." (emphasis added)

cGMP REGULATION FOR
MEDICAL DEVICES
Process validation is
required by the medical device GMP Regulations, 21 CFR Part 820. Section 820.5
requires every finished device manufacturer to:
"...prepare and implement a quality assurance program that is appropriate to the specific device manufactured..."
Section 820.3(n) defines quality assurance as:
"...all activities necessary to verify confidence in the quality of the process used to manufacture a finished device."
When applicable to a specific process, process validation is an essential element in establishing confidence that a process will consistently produce a product meeting the designed quality characteristics.
A generally stated requirement for process validation is contained in section 820.100:
"Written manufacturing specifications and processing procedures shall be established, implemented, and controlled to assure that the device conforms to its original design or any approved changes in that design."
Validation is an essential element in the establishment and implementation of a process procedure, as well as in determining what process controls are required in order to assure conformance to specifications.
Section 820.100(a) (1) states:
"...control measures shall be established to assure that the design basis for the device, components and packaging is correctly translated into approved specifications."
Validation is an essential control for assuring that the specifications for the device and manufacturing process are adequate to produce a device that will conform to the approved design characteristics.
